Personnel target positioning and tracking method and system based on multi-view information fusion

The invention discloses a personnel target positioning and tracking method and system based on multi-view information fusion, and belongs to the field of multi-view pedestrian detection. An existing multi-camera monitoring system is not accurate enough in personnel target positioning and tracking, large in error, tedious in scheme and not beneficial to application and popularization. According to the personnel target positioning and tracking method based on multi-view angle information fusion, a multi-camera system with an overlapped view angle range is utilized, and video data of views of a plurality of cameras are fused, so that the problem that an operator in a scene is often shielded by an environment or other people and cannot be positioned is effectively solved; and by constructing the multi-view personnel positioning network model, the personnel tracking model and the personnel position and trajectory visualization model, the ground position and the position trajectory of the operator in the establishe
