  • Patent number: 7321679
    Abstract: A glass container inspection machine is disclosed for inspecting glass stippled bottles for defects. Stippled bottles are supported at an inspection station and are illuminated with a light source. The stippled bottle is imaged a pixel matrix with the pixels of the image varying in intensity from bright to gray at the points of stippling. A computer evaluates the pixels of the image including a look up table for values to be assigned to specific light intensities from light to black, the plot of the look up table having a high gain portion from black to gray and a continuous low gain portion from gray to white.

  • Patent number: 7245757
    Abstract: A method and a device for detecting containers, e.g. bottles of glass or plastics, or cans made of metal, wood, glass or plastics, which for recycling of materials thereof or reuse thereof are moved in a lying posture and with their axis parallel to direction of transport into or past a detection zone associated with a detector station containing a video camera, a video image analysis of the container being carried out by a video image analyser, and said detector station having an entrance and an exit. There is analysed a sequence of video images of the container whilst it is moved into or past the detection zone of the video camera, and it is determined position and movement of the container in a viewing region of the video camera on the basis of continuous detection of position and movement of the container in the video image.

  • Patent number: 7116814
    Abstract: The image-based container defects detector consists of a plurality of camera units, a sensor unit, a frame grabber, and an image recognizer unit. The sensor unit serves to detect the vehicles entering the inspection station, and transmit a signal to the frame grabber for capturing the vehicle image by triggering the CCD camera thereby obtaining the information about the container's defect position and size. By dexterously utilizing image processing technique, the HIS (hue, saturation and intensity) color is employed to distinguish a normal area from a defected area in the container. Then quad-tree and merge is used to segregate image roughly. As for the non-defected area becoming obscured due to noise is removed using a filter. Finally the defected area is displayed on the screen. The present invention is well-suited for after detection as well as for on-line immediate detection for defect containers.

  • Patent number: 7110590
    Abstract: The method of handling an empty beverage container having a bottom end and a mouth region and includes moving the container, from a return vending machine inlet, in a direction towards an outlet thereof. Through use of the method there is detected by means of a video camera the container when moved in a lying posture into or past a detection zone of the video camera and the manner by which the container is inserted at said inlet. Further, there is determined whether the container is moved into the detection zone bottom end first or mouth region end first. If the container is delivered into the detection zone with its bottom end first, the container is transported to said outlet. If, however, the container is delivered into the detection zone with its mouth region end first, then the container is caused to be returned to the inlet.

  • Patent number: 6993176
    Abstract: The present invention is a method and an apparatus for imaging a liquid-filling container in which a light emitting unit is provided for emitting and irradiating light onto the container and a light receiving unit is provided for receiving the light transmitted through the container. The object of the present invention is to provide such a method and an apparatus for imaging a liquid-filling container. This method and apparatus assures reliable detection of the surface of liquid filled in a container or of foreign substance mixed in the liquid or present in the container or the container material not only when the container is transparent, but also when the container is a colored container of a dark color such as black, dark green or dark brown or the container has a frosted surface of when the liquid filled in the container has a dark color.

  • Patent number: 6973207
    Abstract: An embodiment of the invention provides a method for training a system to inspect a spatially distorted pattern. A digitized image of an object, including a region of interest, is received. The region of interest is further divided in to a plurality of sub-regions. A size of each of the sub-regions is small enough such that a conventional inspecting method can reliably inspect each of the sub-regions. A search tool and an inspecting tool are trained for a respective model for each of the sub-regions. A search tree is built for determining an order for inspecting the sub-regions. A coarse alignment tool is trained for the region of interest. Another embodiment of the invention provides a method for inspecting a spatially distorted pattern. A coarse alignment tool is run to approximately locate a pattern. Search tree information and an approximate location of a root image, found by the coarse alignment tool, is used to locate sub-regions sequentially in an order according to the search tree information.

  • Patent number: 6912303
    Abstract: To test the reliability of a testing apparatus which tests a large number of objects of the same type for one feature, generates a feature signal for each object and checks the feature signal for fulfilment of a first condition, a test object is conducted to the testing apparatus after a number of objects and the feature signal of the test object is checked for the fulfilment of a second condition. The second condition is that the feature signal of the test object corresponds to a previously entered reference value. The reference value can be entered by storing the feature signal of a test object as a reference value.

  • Patent number: 6801649
    Abstract: An efficient and reliable method and apparatus is disclosed that finds a reference point of an object profile within an image when the object is of an unknown size. The object profile is modeled using a synthetic labeled-projection model, which in conjunction with the image, is projected over a portion of the image of the object profile to derive a histogram. The histogram is normalized and a maximum of a first derivative of the histogram is defined for that position. The position of the labeled-projection model is moved relative to the image, and the process is repeated until a selected portion of the image has been examined. The first derivative of the normalized labeled projection is greatest when a feature of the image and the feature denoted by a specific synthetic label of the labeled-projection model are aligned. The method and apparatus can locate the center of the object with reliability, because use of the labeled-projection model and the histogram minimizes the * effects of image artifacts.
