Abstract

The invention discloses a traffic detection system based on millimeter wave radar and video, and belongs to the technical field of data acquisition and processing in intelligent transportation. According to the traffic detection system based on the millimeter wave radar and the video, target information is collected through a millimeter wave radar sensor and a video sensor, world coordinates are converted into image plane coordinates, the position of a target projection collected and detected by the millimeter wave radar sensor on a image plane is determined, the target type is learned and recognized by an image machine, the data collected by the video sensor and the millimeter wave radar are fused, and the speed, coordinates and type of a target are output. According to the traffic detection system based on the millimeter wave radar and the video, the data calculation difficulty of the system is reduced and the system flow is simplified. The data detected by the video sensor and the millimeter wave radar are subjected to data fusion in real time, and the fused target information is sent to a system platform, the calculation amount of the system is reduced, the response time of thesystem is accelerated, and the detection precision is improved.

Description

technical field [0001] The invention belongs to the technical field of data collection and processing in intelligent transportation, and in particular relates to a traffic detection system based on millimeter wave radar and video. Background technique [0002] Most of the existing traffic detection systems use video sensors. The detection accuracy of a single video sensor is not high, the delay of image processing is large, and its accuracy is easily affected by rain, fog and other environments. Later, other types of sensors were gradually added to the traffic detection system, such as millimeter-wave radar, geomagnetic, laser radar and other sensors, and the advantages of different sensors were used to perform multi-sensor data fusion, which greatly improved the detection performance of the system. The radar sensor can detect the position and speed information of the target in real time, and the data processing can reach 20 times per second. It has strong environmental adap...
