Abstract

A video image processing method and system, the method comprising: extracting the shadow of a moving target in a current video image, taking the upper side of the shadow as the bottom edge to take a square upward to obtain a virtual frame of the moving target; The position relationship of the moving target imaginary frame is filtered to obtain the real moving target imaginary frame; the local contour of the moving target is segmented from the current video image, and the local contour center point of the moving target is obtained; from the real existing Determine the imaginary frame of the moving target belonging to the center point of the local contour of the moving target in the imaginary frame of the moving target, as the imaginary frame of the moving target to be adjusted; use the optical flow based on the corner point to track the motion direction of the imaginary frame of the moving target to be adjusted, and The imaginary frame of the moving target to be adjusted is adjusted according to the moving direction, so as to realize the complete segmentation of the moving target. The invention can segment every complete moving object under complex video monitoring environment.

Description

Technical field [0001] This application relates to the field of video image processing, in particular to a video image processing method and system. Background technique [0002] In the traffic management platform, video images are usually processed to achieve vehicle detection. Taking the traditional video image processing method as an example, it is usually to manually set a virtual coil in the video surveillance area (that is, select the video analysis area), and then detect the vehicle characteristics in the virtual coil (such as the darkest shadow in front of the car, license plate, vehicle Color, vehicle type, lights, etc.), vehicle detection is achieved by analyzing vehicle characteristics. [0003] However, practice shows that the above-mentioned video image processing methods can only detect the existence of vehicles, and cannot segment each complete vehicle target in a complex video surveillance environment (such as surveillance video screen jitter, vehicle congestion, e...
