Abstract

The invention relates to a video and radar based vehicle detection method and system. The method comprises the following steps: acquiring radar data of a vehicle on a to-be-detected road; acquiring a video image of the to-be-detected road; based on the radar data and the video image, matching a vehicle figure in the video image with the radar data corresponding to the vehicle on the to-be-detected road, and calculating a vehicle detection index; and superposing a calculation result of the vehicle detection index on the video image for display. According to the invention, video detection and radar detection are integrated, visualization of the radar data can be realized through superposing the data on the video image, the problem of great influences exerted by environment on the video detection can also be solved by use of the radar data, the detection data is enabled to be more comprehensive, and the detection accuracy is also greatly improved.

Description

technical field [0001] The invention relates to the technical field of vehicle detection, in particular to a vehicle detection method and system based on video and radar. Background technique [0002] As urban populations become denser and there are more and more vehicles, alleviating urban traffic congestion has become an urgent problem to be solved for the development of every city. Optimizing urban traffic control signals in real time and reducing people's travel time is an effective means to achieve this goal, and an all-weather, real-time, comprehensive and accurate vehicle information detection device is an inevitable way of this means. [0003] Vehicle detectors currently on the market mainly include contact coil detectors, geomagnetic detectors, and non-contact video detectors and radar detectors. For the contact detector, the biggest defect is that it needs to destroy the road surface for installation, and the detection data is relatively simple. Therefore, non-co...
