Abstract

The invention provides a people number counting method based on image grey level matching. The method comprises the following steps of: S1, obtaining the video streaming image of a monitoring area as an input image; S2, obtaining a difference image via an inter-frame difference method according to the input image, and performing binaryzation processing on the difference image to obtain a moving target area; S3, scanning the moving target area via a rectangular window, and extracting a pedestrian area; S4, taking the grey level information of the pedestrian area as a template, and performing searching and matching in the central point neighbourhood of the pedestrian area in the next image; and S5, storing the central point position information of the pedestrian area to a target chain, so as to obtain the number of people. According to the invention, the grey level information of the pedestrian area is used as the template, and searching and matching are performed in the central point neighbourhood of the pedestrian area in the next image without a need to search in the whole image, thus reducing the operation processing capacity and the processing time, and realizing rapid tracking for pedestrians.

Description

technical field [0001] The invention belongs to the technical field of video image processing and recognition, and in particular relates to a people counting method based on image grayscale matching. Background technique [0002] Intelligent video surveillance is an important application field of computer vision and has broad application prospects. For most intelligent video surveillance systems, moving objects such as people or cars appearing in the scene are obviously important objects of concern. Pedestrian objects are the most important and active elements in the monitoring scene, making pedestrian object detection, recognition and tracking Technology has received the attention of many researchers. [0003] In addition to being widely used in intelligent monitoring of sensitive locations such as museums, airports, parking lots, stations, shopping malls, and banks, pedestrian detection technology also has extremely important research value in intelligent vehicl...
