    摘要: A method for recognizing at least one object in images by a camera and a processor is provided. The at least one object includes content information and operation direction information. The operation direction information includes inspection direction, re-inspection direction, and a combination thereof. The method includes a first re-inspection step, the first re-inspection step includes using the processor to inspect whether the re-inspection direction of one of the at least one object matches a paring relationship. If so, the processor processes the content information of the at least one object and another one object to generate computational result.

    摘要: An object of the invention is to configure an object search device capable of expressing information on shapes and irregularities as features only by images, in a search for an object that is characteristic in shape or irregularity, and performing an accurate search.
    The object search device includes: an image feature extraction unit that is configured with a first neural network, and is configured to input an image to extract an image feature; a three-dimensional data feature extraction unit that is configured with a second neural network, and is configured to input three-dimensional data to extract a three-dimensional data feature; a learning unit that is configured to extract an image feature and a three-dimensional data feature from an image and three-dimensional data of an object obtained from a same individual, respectively, and update an image feature extraction parameter so as to reduce a difference between the image feature and the three-dimensional data feature; and a search unit that is configured to extract image features of a query image and a gallery image of the object by the image feature extraction unit using the updated image feature extraction parameter, and calculate a similarity between the image features of both images to search for the object.

    摘要: Provided is an object recognition device capable of accurately estimating a distance from an own vehicle to an object such as a pedestrian. There are provided: a part specification unit 104 that determines a specific part region in an object by analyzing an image of a region corresponding to the object detected by an overlapping region object detection unit 103; an image information storage unit 105 that stores image information on the part region determined by the part specification unit 104; a three-dimensional information acquisition unit 106 that acquires three-dimensional information of the part region specified by the part specification unit 104 on the basis of the distance information acquired by a distance information acquisition unit 102; a non-overlapping region object detection unit 107 that detects the part region specified by the part specification unit 104 with reference to the image information stored in the image information storage unit 105 for the non-overlapping region; and a distance calculation unit 108 that calculates a distance to an object including the part region on the basis of the detection region information on an image of the part region detected by the non-overlapping region object detection unit 107 and the three-dimensional information acquired by the three-dimensional information acquisition unit 106.
