Problems solved by technology

[0004] And the method in these prior art all has its limitation
First, only spatial calibration is performed, and only the spatial and visual information of the target in a static environment has limited applications; second, only target tracking is performed, and only the position and size of the target in the image can be obtained without spatial information, so the practicability is not strong

Abstract

The embodiment of the invention relates to a vehicle tracking method. The method comprises the following steps: acquiring a transfer matrix between radar data and a camera image by utilizing a calibration plate; taking a space corresponding relation and a time space corresponding relation based on the transfer matrix of the radar data and the camera image as an initial condition, learning by utilizing a supervision machine in a tracking process to acquire detection parameters; and correcting detector parameters of a detector based on the credibility of a tracking result. The embodiment of the invention further relates to a vehicle tracking device.

Description

technical field [0001] The disclosure belongs to the technical field of computer vision and graphics processing, and in particular relates to a vehicle tracking method and device based on computer vision and graphics processing technology. Background technique [0002] Vehicle tracking and detection is an important application direction in the field of computer vision and graphics processing. In this field, there have been researches on vehicle tracking and detection using laser, radar, cameras such as monocular or stereo cameras, and multi-sensor fusion. [0003] Vehicle tracking based on multi-sensors can detect the position, speed, trajectory and other information of a specific vehicle in space. This has important practical significance for detecting abnormal vehicles and avoiding potential risks. The robustness of the detection cannot be guaranteed due to differences in the representation of the vehicle in different states when using multiple sensors including vision s...
