Multi-camera collaboration-based image processing method and video surveillance system

A multi-camera collaboration-based image processing method, applied to a video surveillance system, wherein the video surveillance system comprises at least two cameras and an analysis unit, the at least two cameras comprise a first camera and a second camera, and the method comprises:

• separately obtaining, respectively by the first camera and the second camera, a photographed first image and a photographed second image;
• receiving, by the first camera and the second camera, indication information of a target task, wherein the target task is image recognition and the indication information of the target task indicates characteristic information of a to-be-recognized image, a similarity condition and a process to be performed on a target object in the first and second photographed images;
• separately generating, respectively by the first camera and the second camera, first execution result information and second execution result information of the target task based on the indication information of the target task, wherein the first execution result information comprises first processing result information related to characteristic information of the target object in the first image, and the second execution result information comprises second processing result information related to characteristic information of the target object in the second image;
• sending, by the first camera and the second camera, the first execution result information and the second execution result information to the analysis unit;
• and
• determining, by the analysis unit, third execution result information of the target task based on the first execution result information and the second execution result information;
• wherein the step of generating, by the first camera, first execution result information of the target task comprises:
• extracting, by the first camera, first characteristic information of the target object from the first image;
• and
• generating, by the first camera, based on the first characteristic information and the characteristic information of the to-be-recognized image, first similarity information between a to-be-recognized object and the target object in the first image;
• and
• wherein the step of sending, by the first camera, the first execution result information to the analysis unit, the method further comprises:
• determining, by the first camera, the first similarity information meets the similarity condition.
