Abstract

The present invention provides a motion information and trajectory association-based video pedestrian detection and tracking method. Pedestrian detection comprises: detecting motion by using a frame difference method; first detecting a motion area in a video in combination with a morphological method of digital image processing; then extracting a feature from the motion area in a manner of sliding window searching; and performing classification by using a previously trained pedestrian detection classifier, to finally obtain a classification result. The tracking method comprises: using the pedestrian detection result obtained in the previous step as input of this step; in the beginning, initializing a tracker for each detected pedestrian, wherein each tracker comprises history motion information and appearance information of an object; and when a current frame is being processed, extracting location information and appearance information for each input detection result, and establishing a correlation matrix based on this to associate with a tracking object of a previous frame, and finally obtaining a tracking trajectory of a pedestrian. The present invention has good real-time performance, and also has good robustness in a relatively complex situation.

Description

technical field [0001] The invention belongs to the technical field of digital image processing and relates to video pedestrian detection and tracking technology. technical background [0002] With the development of modern computer technology and the wide application of computer vision principles, the research on pedestrian detection and tracking in video using artificial intelligence and computer image processing technology is becoming more and more popular. Video pedestrian detection and tracking is to find out the position and trajectory of pedestrians in a video sequence. As the basic technology of modern intelligent monitoring, it can be applied to various monitoring scenarios, such as roads, stations and airports. Pedestrian detection and tracking can be divided into two parts, namely pedestrian detection and pedestrian tracking. [0003] Commonly used pedestrian detection techniques are as follows: [0004] 1) Pedestrian detection method based on background modeli...
