COMPUTER VISION NAVIGATION
A system for computer-aided visual recognition of products may help a customer navigate to a selected product in a retail store. A customer can direct a mobile computing device camera at one or more targeted products displayed on store shelves. Image recognition operations can be carried out to compare the targeted product image(s) against images from a prepopulated product image store of known products. Upon a positive match, shelf location information of the identified targeted product(s) may be used to determine the current location of the customer. An in-store destination location is defined by the shelf location for the selected product. A route may be calculated to navigate the customer from the current location to the destination location.
In recent years, mobile computing devices have become ubiquitous around the world in many societies. Worldwide, hundreds of millions of mobile computing devices are sold every year. Such devices may be used frequently throughout each day, and thus may be carried by users at nearly all times. Such mobile computing devices include, but are not limited to: smartphones, tablets, e-readers, wearable computing devices such as smart glasses and smartwatches, and other types of mobile electronic computing devices.
One common use of mobile computing devices is navigation. Mobile devices can determine the current location of the user through the satellite-based Global Positioning System (GPS), cellular tower networks, other active or passive networks, and combinations thereof, and then guide the user to a desired destination using by recalling relevant maps, calculating the most efficient routes, and providing turn-by-turn directions to the destination.
Indoor navigation can be provided in several ways. One current implementation is carried out by installing beacons in and around buildings, where the location of each beacon is known and each beacon emits a unique identifier. Some indoor navigation systems work on principles similar to GPS, while others operate by detecting the respective signal strengths of multiple beacons with the presumption that greater distance from the beacon equates to a weaker beacon signal. Another implementation of indoor navigation uses dead reckoning and relies on the internal sensors of the mobile computing device, such as the accelerometers and compass.
However, current navigation systems exhibit some drawbacks. For example, GPS signals may become significantly weaker and essentially useless as a user enters into a building or other covered space. Indoor navigation can be costly and expensive to set up and maintain, and may be error prone and/or lack accuracy to a degree that is unacceptable to many users.

After obtaining the information, navigation server 100 can query store map database 130 with the product identifier to determine the in-store location where the image was captured.
In one embodiment, processor 310 is operable to receive images captured by camera 350, as directed by the customer. Processor 310 can also be operable to control the other components 320, 330, 340, 350 of mobile computing device 300. Processor 310 can also be operable to process signals received by the mobile computing device 300. While a single processor 310 is illustrated, it should be appreciated that the term “processor” can include two or more processors that operate in an individual or distributed manner.
Display 320 may be positioned to project an image within the customer's field of view. While the customer directs camera 350 at the targeted product 220, video or still images captured by camera 350 can be shown to the consumer on display 320. Display 320 can be configured to display text, graphics, images, illustrations, user interface objects, and/or any other video signals to the customer.
In an embodiment, transmitter 330 is configured to transmit signals generated by components 310, 320, 350, or 360 of mobile computing device 300. Processor 310 can direct signals from mobile computing device 300 to navigation server 100 via transmitter 330. In an embodiment, transmitter 330 comprises an electrical communication element within processor 310. In one embodiment, processor 310 is operable to direct signals to transmitter 330 and transmitter 330 is operable to transmit the signals from mobile computing device 300 to, for example, navigation server 100 via network 230.
In an embodiment, receiver 340 is configured to receive signals and to direct signals that have been received to processor 310 for further processing and/or recording. Receiver 340 may be operable to receive transmissions via network 230 and subsequently communicate the transmissions to processor 310. In various embodiments, receiver 340 comprises an electrical communication element within processor 310. In some embodiments of the present disclosure, receiver 340 and transmitter 330 comprises an integral component.
Transmitter 330 and receiver 340 are adapted to communicate over a Wi-Fi network, allowing mobile computing device 300 to exchange data wirelessly (using radio waves or the like) over a computer network, including high-speed Internet connections. Transmitter 330 and receiver 340 may also apply Bluetooth® standards for exchanging data by using short-wavelength radio transmissions, thereby creating a personal area network (PAN). In an embodiment, transmitter 330 and receiver 340 also apply 3G and/or 4G as defined by the International Mobile Telecommunications-2000 (IMT-2000) specifications promulgated by the International Telecommunication Union.

Speaker can be positioned within the consumer's range of hearing while using mobile computing device 300. Audio content transmitted from navigation server 100 can be played for the consumer through the speaker. Receiver 340 can receive an audio signal from navigation server 100 and direct the audio signal to processor 310. Processor 310 may then control the speaker to emit the audio content.
In operation, navigation system 200 may facilitate navigation from a customer's current location to a location of a selected product within a retail store. Embodiments of the present disclosure can determine the current location within a retail store by identifying products on store shelves with a camera of a mobile computing device and then by utilizing computer image recognition techniques. According to one embodiment, the known shelf location of identified products can be presumed to be the in-store current location of the customer. Referring now to
Method 400 begins at operation 410, where the customer selects one or more products of interest and requests navigation to the product in a particular store. In one embodiment, the customer selects the product of interest by making an input on an object in a graphical user interface displayed on the mobile computing device. In one embodiment, the customer conducts a text search for the product on an app, web interface, or the like. In other embodiments, the customer selects the product of interest by other means already known in the art or not yet known in the art.
In an embodiment of operation 410, the customer requests to receive navigation to the selected product at a selected retail store location. In one embodiment, the selected retail store is the closet retail store to the customer's current location. Thus, if the customer is already at or in a retail store location, that store location may be selected. In another embodiment, the customer has a preferred retail store location, which may be selected. In an embodiment, if the selected product is not in stock at the closest and/or preferred store location, but the selected product is available at other nearby store locations, a retail store location may be selected based, in part, on the availability of the selected product. In one embodiment, the selected product is a product that the customer wishes to purchase.
At operation 415, the customer's current location is determined or approximated. If the mobile computing device can receive GPS signals, cellular network signals, or other signals operational to ascertain the current location, the mobile computing device may do so to determine the current location. If the current location is determined to be at a retail store location, the mobile computing device may transition into an “in-store” mode and skip to operation 430. In one embodiment, if the mobile computing device can receive a wireless network signal known to be produced at the retail location, for example a Wi-Fi network provided by the retailer, it may be presumed that the customer's current location is at the retail store location.
At operation 420, navigation is provided to the selected retail store location using GPS, cellular network signals, combinations thereof, and other methods of providing location information to a mobile computing device. Maps of streets, public transportation, walking paths, and other possible routes may be downloaded from the Internet via Network 230 or may be stored on the mobile computing device. Such maps may be utilized to provide directions to the customer, on a turn-by-turn basis or otherwise, to travel to the selected retail store.
In one embodiment, upon arriving at the selected retail store location, the customer may be instructed to enter the premises and advance to the aisle where the selected product may be found. Upon entering the store, the mobile computing device may transition into an “in-store” mode and navigation may then be provided to the location of the selected product within the store.
At operation 430, the in-store location of the selected product is determined. In an embodiment, the location of the selected product may be determined by querying store map database 130 for the location of the particular selected product. The in-store location may comprise an aisle number, a bay number, a display number, a shelf number, combinations of the foregoing, or other indicia of in-store locations. In one embodiment, the in-store location comprises coordinates.
At operation 440, the mobile computing device 300 may capture images within the store via camera 350 as the customer walks. In embodiments where the mobile computing device comprises smart glasses 300, camera 350 may capture essentially all images as seen by the customer while the mobile computing device 300 is in navigation and in-store modes. In other words, as the customer faces one or more products 220 on the shelves while wearing the smart glasses 300, the camera 350 may capture images of the products 220. In other embodiments, the customer may manually aim the camera 350 of a mobile computing device at various products 220 on the shelves. Images captured by camera 350 may include various products 220. Such products may be referred to herein as “targeted products.”
According to an embodiment, while the mobile computing device remains in the in-store mode, it can repeatedly receive and analyze images captured by the camera to determine the identity of targeted products. In one embodiment, the captured images are transmitted to the processor of the mobile computing device for analysis and product recognition. In other embodiments, the captured images are transmitted to navigation server 100. In alternative embodiments, preliminary processing on captured images is carried out by the processor of the mobile computing device, after which selected one or more images and the results of said preliminary processing are transmitted to navigation server 100 for product recognition.
In one embodiment of operation 440, the mobile computing device is set to in-store mode. According to this embodiment, while the device remains in in-store mode, multiple image frames are captured. In one embodiment, the mobile computing device may remain in in-store mode and therefore continually capture images until the selected product has been reached. In one embodiment, each captured frame is analyzed. In another embodiment, selected frames are analyzed.
According to an embodiment, at operation 440, preliminary processing that is carried out by the processor of the mobile computing device comprises detection of features in each of the one or more selected captured images. In one embodiment, a feature detection algorithm known as SURF (Speeded-Up Robust Features) is carried out by the processor of the mobile computing device to detect features in the one or more images. In other embodiments, other feature detection algorithms are carried out to detect features in the one or more images using a feature detection algorithm that is known in the art or yet to be known. In an embodiment, feature detection operations are performed on multiple images captured sequentially from the camera on the mobile computing device.
Upon completing the preliminary analysis, a selection of one or more images exhibiting a threshold number of detected features may be made from the multiple captured images to transmit to navigation server 100 for further analysis and product matching. In another embodiment, additional analysis is carried out to make a selection of one or more images to transmit to navigation server 100.
At operation 450, one or more selected images of targeted products are transferred to navigation server 100. As described herein, the transmission may take place over any one of a variety of network types or combinations thereof.
At operation 460, the transmitted images are received at navigation server 100 and compared to images at product image store 120 for matches. According to embodiments of the present disclosure, navigation server 100 is adapted to compensate for image rotation and scaling differences between captured images and images at product image store 120. In one embodiment of operation 460, a match score is determined between an image captured by the camera and an image at product image store 120. After carrying out image comparison operations between the received image and the images at product image store 120, the highest match score may determine the closest match.
In one embodiment, a minimum score threshold is instituted so that if no match score exceeds the threshold, it may be presumed that the customer image does not depict a product that the retailer offers. In one embodiment, machine learning techniques are carried out with respect to the minimum score threshold by inputting multiple known matching image pairs and thus building a model to determine if image pairs are similar enough to constitute a match.
In one embodiment of operation 460, navigation server 100 is adapted to identify multiple targeted products for each image captured by the mobile computing device. Each image may be split into multiple constituent images, with each constituent image depicting a targeted product captured by the camera.
It is an objective of some embodiments of the present disclosure to prevent false positive identifications of products that are presumably at their proper location on the store shelves, but have actually been moved. For example, if a customer directs camera 350 at a shopping cart that contains one or more products, images of those products may be transmitted to navigation server 100 for matching. Assuming that the cart has been moved a significant distance from the original shelf location of the products, a positive match between the products in the cart and images at product image store 120 may lead to an incorrect conclusion regarding the current location since the targeted product was not actually at its proper location on the shelf. Thus, it may be preferable to ignore products that are in a shopping cart or otherwise not on the shelves. Accordingly, embodiments of the present disclosure may employee several qualification techniques to ensure the integrity of navigation system 100 and prevent false identification of products not on the store shelves.
In one embodiment of the present disclosure, a qualification technique incorporates the assumption that if multiples of the same product are in an image, then those products are together on a shelf. This technique operates on the assumption that shoppers are less likely to purchase multiples of the same product at the same time and it further operates on the fact that the same products are found next to each other on the store shelf. Thus, if a captured image has been split into multiple constituent images, each of which depicts the same product, it may be presumed that those products are on the shelf and the known shelf location, as stored at store map database 130, may be used as the current location.
Likewise, in one embodiment of the present disclosure, if a captured image depicts multiple products, each one comprising products in a shared category (for example interchangeable products from different brands), which have a low probability of being purchased together but may be found next to each other on the store shelf, it may be presumed that those products are at their proper shelf location.
Conversely, in one embodiment of the present disclosure, if a captured image depicts multiple different products in close proximity to each other, it may be presumed that those products are not at their proper shelf location and may be disregarded.
In another embodiment of the present disclosure, the customer may be requested by the mobile computing device to direct camera 350 at a store shelf so that an image of the targeted products placed there may be captured and transmitted to navigation server 100 for comparison.
As would be understood by a person of ordinary skill in the art having the benefit of the present disclosure, images captured by cameras on a mobile computing device may comprise relatively low resolution in comparison to images generated by a dedicated camera. Thus, lower thresholds may be instituted in the matching algorithm in order to compensate for anticipated low resolution images received from customers.
In one embodiment of operation 460, recognition and analysis of text, product codes (such as UPC/bar codes), and other information on targeted products or packaging may be used to assist product matching. For example, the name of a product may appear as text on the product packaging. An image of the packaging may depict the product name. By recognizing and extracting such text from the image, the result of the matching operation 460 may be validated.
In one embodiment, a result of operation 460 is that a product has been matched to an image captured by the camera. In some embodiments, multiple products are identified from the received images. If so desired, navigation server 100 may be enabled to identify any number of products depicted. In some embodiments, multiple products are potentially selected from each image frame captured by the customer's camera.
In one embodiment, navigation server 100 may receive multiple images or image frames (i.e., from a video feed), each image or image frame depicting a product. In one embodiment, navigation server 100 may be configured to only confirm a product selection after identifying the product in a minimum quantity of consecutive images or frames, as captured by the customer's mobile computing device. In this manner, navigation server 100 may minimize false positive identifications of products.
At operation 470, navigation server 100 queries product image store 120 for location information related to the one or more identified targeted products. In one embodiment, such information may include an aisle number, a bay number, a display number, a shelf number, location coordinates, combinations of the foregoing, or other indicia of in-store locations. According to embodiments, the location of identified targeted products may be presumed to be the current location.
At operation 480, the mobile computing device calculates a route and provides directions for the customer to navigate from the current location to the in-store location of the selected product. According to embodiments, the route may be optimized for shortest path, least obstacles, easiest maneuvering with a shopping cart, or other selected considerations. In one embodiment, a navigation user interface is displayed to the customer, depicting a map of the store and the calculated route.
In one embodiment of the present disclosure, a form of dead reckoning may be additionally employed to determine the customer's current location. In particular, navigation system 200 may continually track the customer's movement beginning upon entrance into the store. In embodiments, certain assumptions may be utilized, such as a maximum walking velocity, to validate a current location determination. Additionally, embodiments of the mobile computing device comprise a compass, accelerometers, and other sensors that may register movement and/or orientation of the mobile computing device. Data generated by such sensors may also be used to validate a current location determination.
At operation 485, as the customer walks along the route, but before arriving at the selected product destination, the customer's location is checked to determine if the customer has arrived at the selected product destination. If not, operations 440, 450, 460, 470, 480, and 485 may be repeated in a cycle to update the current location and display a map of the route reflecting the updated current location. Upon arrival at the selected product destination, method 400 completes at operation 490.
