Visual field display system, visual field display method, and visual field display program

摘要

Provided is a visual field display system capable of presenting a range in which a camera can capture an entire monitoring object or a part of the monitoring object to a certain extent in an easy-to-understand manner. The projection unit 5 is a plane obtained by translating a monitoring target area that defines a range that is a target for confirming the shooting status of the camera, and is a plane determined based on the height of the monitoring target shot by the camera. A position in an image obtained from the camera is projected on a plurality of monitoring surface portions that are minutes, and a field of view that can be captured by the camera without being obstructed by an obstacle is specified. The integration unit 6 integrates the field of view within each monitoring surface segment. The display control unit 7 causes the display device to display the integration result of the field of view.
