Pedestrian flow monitoring method based on pedestrian detection and tracking

Abstract

The invention discloses a pedestrian flow monitoring method based on pedestrian detection and tracking. The method includes: acquiring and decoding a camera video stream to obtain single-frame RGB images, performing pedestrian detection on each image frame to obtain a group of pedestrian positions, calculating similarity, matching the pedestrians of every two adjacent image frames so as to track the pedestrians and obtain motion trajectory of each pedestrian, setting detection lines in the monitoring video, and judging pedestrian flow in different directions through the obtained pedestrian trajectories. The method is based the latest developments of pedestrian detection in computer vision, high in detection accuracy, fast in detection and promising in development prospect. By combining the method with a fast tracking method based on similarity and using a multi-scale detection method from sparsity to density, detection speed is further increased, fast pedestrian tracking is realized, detection and tracking speed can reach 10FPS on a current common computer, and practical level is reached.

Description

technical field [0001] The invention belongs to the technical field of video image processing and pattern recognition, and in particular relates to a pedestrian flow monitoring method based on pedestrian detection and tracking. Background technique [0002] Human body or pedestrian detection and tracking technology has a wide range of application values ​​in the fields of car assisted driving and video surveillance. In the process of driving, serious pedestrian injury accidents may be caused due to bad weather or driver fatigue and negligence. Therefore, there is an urgent need for assisted driving technology that can automatically detect pedestrians and remind the driver, and this assisted driving is required. The technology is able to detect pedestrians as quickly and accurately as possible. [0003] In the field of video surveillance, traditional video surveillance methods require specific personnel to review the content captured by video surveillance cameras to complete...
