Abstract

The invention provides a method and a system for processing a background image collected in a moving target detection, comprising the following steps: obtaining video images of successive frames, extracting successive frame data of multiple points in a fixed region in the video images of the successive frames, sorting the successive frame data of each point, extracting a median of the sorted sequence of each point, and obtaining the background image of a current frame. The technology further comprises the steps of obtaining a video image of a new frame, extracting data of the new frame of a plurality of points in the fixed region in the video image of the new frame, deleting the data of an oldest frame in the successive frames, carrying out insertion sorting for the data of the new frame, extracting a new median of the sorted sequence, and obtaining the background image of a current frame. The technology can be adapted to different background conditions, can also simply and fast calculate and efficiently prevent the incidence of vehicle motion trace residue in the background image, thereby enhancing the efficiency of the detection.

Description

Technical field [0001] The present invention relates to a moving target detection method and system, and in particular to a background image processing method and system collected in moving target detection. Background technique [0002] In today’s society, urban development is very rapid. Urban population and vehicles are growing rapidly, traffic flow is increasing day by day, traffic congestion is becoming more and more serious, and the transportation system is facing tremendous pressure. Traffic problems have become a major problem in urban management. Hindering the development of the city, especially the occurrence of various vehicle violations anytime and anywhere, making the monitoring of urban traffic very difficult, and moving target video detection technology has emerged to monitor the traffic conditions of vehicles. [0003] Facing the rapid development of highway traffic and the increase of vehicle speed, it is inevitable to study advanced vehicle detection algorithms....
