  • Patent number: 9811738
    Abstract: An appearance presentation system is provided. The appearance presentation system can present the appearance of an object to be monitored at a position that the user designates in an image such that the user can previously grasp the extent to which the image to be captured with a camera is suitable for an image recognition process. A display control unit 10 displays, on a display device, an image obtained by superimposing an object indicator indicating the object to be monitored on an image to be captured when the camera of which position and posture are determined shoots a predetermined region to be monitored. A position designation reception unit 4 receives the designation of the position of the object indicator in the image. An image generation unit 3 generates an image to be captured when the camera shoots a state in which the object to be monitored is placed at a position that is in the region to be monitored and that corresponds to the position designated in the image.
