  • Patent number: 11468682
    Abstract: A target object identification system includes a first camera, a second camera, and a processor. The first camera acquires an image of a first target region. The second camera synchronously acquires an image of a second target region. The second target region includes part or all of the first target region. Resolution of the first camera is higher than that of the second camera, and field of view of the second camera is greater than that of the first camera. The processor identifies first target objects according to the image of the first target region, and second target objects according to the image of the second target region, and determines association relationships between the first target objects in the image of the first target region and the second target object in the synchronously acquired image of the second target region.

  • Patent number: 10197421
    Abstract: A device for detecting posture change of a operation part in a camera and a method for restoring posture are disclosed. The device may include a photo interrupter and a photoelectric baffle structure including a plurality of baffle pieces fixed on a base. The baffle pieces may include a first baffle piece and remaining second baffle pieces of a length specification different from that of the first baffle piece, and there is a gap between two adjacent baffle pieces. An output signal from the photo interrupter changes according to the aligning relationship between the photo interrupter and the baffle pieces. One of the photoelectric baffle structure and the photo interrupter may follow the motion of an operation part of the camera while the other one remains unmoved, so that a posture change of the operation part may be detected based on the output signal from the photo interrupter.
