  • Patent number: 9548014
    Abstract: A plurality of types of arrangement pattern candidates are generated. Each arrangement pattern candidate is an arrangement pattern candidate of a plurality of indices in a physical space used to calculate the position and orientation of the viewpoint. The arrangement pattern candidate enables observation of a predetermined number or more of indices from a position in an area where mixed reality can be experienced in the physical space. Information representing the arrangement pattern of a plurality of indices in the physical space is generated by using the generated types of arrangement pattern candidates.

  • Patent number: 9542729
    Abstract: There is provided an image processing device including a depth acquisition unit and a smoothing processing unit. The depth acquisition unit acquires a depth to a subject in correlation with a pixel in a captured image of the subject, and the smoothing processing unit designates a pixel in a region excluding a predetermined region in the image as a target pixel, and performs a smoothing process of the degree according to the depth corresponding to the target pixel for a pixel value of the target pixel in a predetermined direction. This causes a pixel in a region excluding the predetermined region in the image to be blurred, thereby generating a panning image.

  • Patent number: 9519286
    Abstract: The proposed system, Delayed Telop Aid (DTA), improves the teleoperator's ability to control the vehicle in a three step process. First, DTA predicts robot motion given the operators commands. Second, DTA creates synthetic images to produce a video feed that looks as if the robot communication link had no delay and no reduced bandwidth. Finally, DTA performs closed loop control on the robot platform to ensure that the robot follows the operator's commands. A closed loop control of the platform makes sure that the predicted pose after the delay (and therefore the image presented to the operator) is achieved by the platform. This abstracts away the latency-sensitive parts of the robot control, making the robot's behavior stable in the presence of poorly characterized latency between the operator and the vehicle.

  • Patent number: 9395180
    Abstract: A plurality of distance sensors are used to measure the surface shape map of objects in the presence of relative motions between the object and sensor in the measurement directions of the sensors. The method involves making multiple sequential measurements from a group of sensors while the object moves longitudinally relative to the sensors. The central idea of the invention is the observation that surface shape features appear in delayed sequence as the observed surface moves longitudinally relative to the sensor array, while any relative motions in the measurement directions appear simultaneously at all sensors. Mathematical procedures are used to identify the relative motions from within the measurements. These motions are then subtracted from the sensor reading to determine the surface shape map of the measured object.

In some examples, structured light patterns may be projected onto the AR scene from a light source in the same plane as the AR camera in order to preserve a consistent reference point for detecting the structured light pattern. The AR camera may detect the structured light patterns and determine the location of the AR camera based on a distance analysis of the detected structured light patterns. Based on the changing locations of the AR camera, the system may track the movement of the AR camera as its location relative to the AR scene changes.

  • Patent number: 9176221
    Abstract: When estimating distance to an object in an image using a single camera, data acquired by an onboard accelerometer is analyzed to determine camera speed as the user takes a video of the object of interest. The compression that results during video processing is used to derive motion vectors for the object of interest in the scene. The motion vectors have an opposite direction to the camera motion and a magnitude that is a function of the unknown object distance and a known magnification level. The object distance is calculated from the estimated velocity and motion vector magnitude.

  • Patent number: 9171362
    Abstract: The method of the invention comprises: obtaining a sequence of at least two images, with different levels of illumination; extracting the region containing the sign in the image; calculating the luminance values of the signs; and obtaining the difference in luminance of the sign corresponding to the two levels of illumination. The value obtained is the luminance of the sign (11) corresponding to an illumination equal to the difference between the illuminations, or additional illumination. This result is based on the additive property of luminance, according to which the luminance of a sign is the sum of the luminance produced by each source of illumination. A basic illumination device (5), an additional illumination device (7), at least one camera for taking images, and image recording, positioning and synchronism systems are required to implement the method.

  • Patent number: 9153029
    Abstract: A two-dimensional pattern comprises a plurality of R-planes each comprising a tiling of a corresponding R-ary block, being a block of radix R integer values, where for each dimension of the pattern, the least common multiple of the sizes of the tiled blocks in that dimension is greater than the size of the tiling that dimension, and any sub-block of a size less than the tiled blocks occurs on a regular grid with the same periodicity as the tiled block for that R-plane. The pattern may be used in determining a position of a location captured in an image by projecting the pattern onto a scene. An image is captured. The method determines from the captured image a sub-block associated with the location and constructs, a unique integer value for each R-plane. The unique integer values from each R-plane are used to determine the location in the image.
