Vehicle detection and tracking method and device, apparatus, and storage medium

Abstract

The invention discloses a vehicle detection and tracking method and device, an apparatus and a medium. The method comprises the following steps: extracting a feature descriptor of an image of a vehicle to be tracked; detecting A target vehicle tracking object in an image of a region to be detected by using a trained vehicle detection model including features of a vehicle normally visible region component and feature of a vehicle easily occluded region component; Extracting feature descriptors of target vehicle tracking object images; performing Local sensitive hash matching and purification of feature descriptors; Determining the number of feature descriptors after purification and judging whether the number is larger than a preset threshold value; If so, the target vehicle tracking object is tracked when the area hue value of the target vehicle tracking object is within a preset hue value range. That is, the present invention utilizes a model including a common visible area and a easily occluded area to perform image detection, detects a vehicle to be tracked through a local sensitive hash matching, realizes vehicle tracking, effectively avoids the problem of vehicle leakage detection due to occlusion, and improves tracking accuracy.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a vehicle detection and tracking method, device, equipment and storage medium. Background technique [0002] Vehicle detection and tracking are key components of intelligent transportation systems. They have broad application prospects in areas such as traffic guidance, assisted driving systems, and road monitoring, and can provide important clues and evidence for public security cases and traffic accident investigations. However, due to the complex imaging conditions in real scenes, vehicle detection and tracking face many difficulties, especially the occlusion problem. The existence of multiple targets in a complex road environment is the main reason for the mutual occlusion between vehicles. The occlusion makes the target information missing, which is easy to cause the target to be missed and lost. Contents of the invention [0003] In view of this, the obj...
