Method and system for estimating network topological relations of cameras in monitoring scenes

The invention relates to the technical field of security and protection, and provides a method and system for establishing network topological relations of cameras in monitoring scenes. The method comprises the steps of resolving the monitoring scenes in video streams shot in a monitoring network into grids, obtaining color histogram information of light streams of all grids in the monitoring scenes, conducting clustering on the grids in the monitoring scenes according to the color histogram information of the light streams of the grids in the monitoring scenes to obtain semantic region segmentation results of the monitoring scenes, and determining the network topological relations among all the cameras according to the semantic region segmentation results in the monitoring scenes. The method and system for establishing the network topological relations among the cameras in the monitoring scenes solves the problem that in the prior art, due to the fact that the topological relations among the cameras are all
