Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] Such as figure 1 As shown, the monitoring video pedestrian detection and matching method provided by the embodiment of the present invention specifically includes the following steps:

[0036] S1: Frame the target image to be matched in a single frame image and obtain the square area coordinates of the pedestrian target by extracting the global transformation histogram (Census Transform Histogram, CENTRIST) feature of the image in the video image sequence;

[0037] S2: According to the number b of pedestrian targets in frame a of each video image sequence a build b a target sequence, star...

Abstract

The invention belongs to the field of video image data processing and discloses a surveillance video pedestrian detection matching method which comprises a video pedestrian target detection step, an inter-frame common target relevance step, target sequence and to-be-matched target characteristic extraction step, a characteristic similarity calculation step and a target matching distinguishing step. Due to the fact that no big displacement exists between adjacent inter-frame pedestrian targets, a target sequence is obtained by utilizing detected location information of a pedestrian to conduct associating on the common target. One method for extracting target sequence features is to extract multi-frame grey level histogram features of the target sequence, and the other method is to extract a physical configuration audit (PCA) template. Due to the adoption of the multi-frame information, the surveillance video pedestrian detection matching method possesses better stability and matching accuracy compared with single frame target matching. A matching determination method utilizes iteration features to integrate the similarity of the two features to make judgment and obtain a matching result.

Description

technical field [0001] The invention belongs to the field of video image data processing, and more specifically relates to a monitoring video pedestrian detection and matching method. Background technique [0002] Most of the camera fields of view in the monitoring system are non-overlapping and target pedestrians. The purpose of studying the tracking and matching of pedestrian targets in a multi-view surveillance system is to solve the computer problems of targets in different surveillance videos in a certain area surveillance system. Automatically search for issues. The basic framework to solve the target matching problem generally includes the steps of target feature extraction, establishment of target feature database, and feature similarity measurement. [0003] At present, the main types of single-frame target feature extraction in surveillance videos at home and abroad are: (1) Appearance model matching methods based on color features, such as color histogram appeara...
