  • Patent number: 11494922
    Abstract: An object tracking device includes an image buffer configured to store a plurality of images included in a video, a detection part configured to detect an object position by executing a detection process with respect to an object reflected in the plurality of images, a tracking part configured to execute a tracking process with respect to a tracking-image string representing a scope of images ranging from an image producing an object-detection result and an image producing a next object-detection process, and an integration part configured to calculate an integrative object position by integrating a detection result and a tracking result. Herein, the scope of images is determined based on an execution timing or a termination timing of the detection process, thus executing the detection process and the tracking process in parallel.

  • Patent number: 10867394
    Abstract: An object tracking means tracks objects in a video image. An object consolidation determination means generates a “container” which includes a plurality of objects located in proximity.

  • Patent number: 9830336
    Abstract: An image comparison unit (81) compares a query image with a registered image to detect, in the registered image, a region corresponding to the query image. An action information determining unit (82), on the basis of intermediate information in which sub-region information identifying sub-regions in the registered image and action information representing information processing to be executed by a target device are associated with each other, identifies sub-regions on the basis of the sub-region information, chooses a sub-region having the highest degree of matching with the detected region among the identified sub-regions, and identifies action information corresponding to the chosen sub-region. An action information execution unit (83) causes the target device to execute information processing corresponding to the action information.

  • Patent number: 8520981
    Abstract: The arrangements of feature points are computed based on feature points acquired from checking target images. The feature amount having invariants as elements regarding a geometrical transformation is generated for each of the checking target images based on a computed result. And when checking whether or not the feature point arrangements of the checking target images are the same feature point arrangements by using the feature point amounts of the checking target images, at least each of the feature point arrangements that are bases for generating the feature amounts is stored, and a parameter regarding the geometrical transformation is computed based on the feature point arrangements of the checking target images. By utilizing the computed parameter regarding the geometrical transformation, whether or not the feature point arrangements of the checking target images are the same feature point arrangements is checked.

  • Patent number: 8199970
    Abstract: An arithmetic device (400) calculates a moving amount based on an image sensed before movement and an image sensed after movement. The arithmetic device (400) generates a difference image with minimum noise using the calculated moving amount. The arithmetic device (400) removes noise from the difference image by performing image processing of the difference image. The arithmetic device (400) determines based on the size of a binarized region in a binarized difference image whether an obstacle exists. This makes it possible to accurately calculate the moving amount and accurately determine whether an obstacle exists.
