  • Publication number: 20220038677
    Abstract: An image display method used by an image surveillance system is provided. The image surveillance system includes a plurality of cameras. The camera is configured to shoot a part of a physical environment to form a real-time image. The image display method has the following steps: First, a three-dimensional space model corresponding to the physical environment is established. Next, based on the height, the shooting angle and the focal length of the camera, a corresponding viewing frustum is established for each of the camera. According to the viewing frustum, a shooting coverage area of the camera in the physical environment is obtained. Next, a virtual coverage area corresponding to the shooting coverage area is searched out in the three-dimensional space model. Next, the real-time image is imported to a three-dimensional space model and projected to the virtual coverage area.
