Vehicle continuous tracking method based on radar detection

Abstract

The invention discloses a vehicle continuous tracking method based on radar detection, and relates to the technical field of radars. The method is realized based on periodic radar detection data, and comprises the following steps: determining a tracker in an on state corresponding to a moving vehicle according to an obtained vehicle position coordinate and a vehicle running speed of the moving vehicle; and meanwhile, determining a tracker corresponding to the static vehicle based on a keeping mechanism of the tracker, then based on the data of the moving vehicle, updating tracker position coordinates and pre-judgment information of the tracker corresponding to the moving vehicle, and keeping the tracker position coordinates and the pre-judgment information of the tracker corresponding to the static vehicle to be unchanged. According to the method, the defect that the radar can only detect the moving vehicle is overcome through the updating and maintaining mechanism of the trackers so that the trackers of the same vehicle cannot be turned on and off repeatedly due to the states of the trackers, the continuity of the trackers is ensured, the missing detection is reduced, and the detection accuracy of the vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to a continuous tracking method for vehicles based on radar detection. Background technique [0002] In order to obtain information such as traffic flow, vehicle speed, and queue length at the intersection, it is necessary to detect and track the vehicles at the intersection. The conventional means of intersection detection are generally to set up video traffic detectors, geomagnetic devices, etc., but these devices have certain limitations in detection. It is not possible to obtain all the information accurately. Millimeter-wave traffic radar has the advantages of all-weather operation, no detection blind spot, installation and maintenance costs, etc., which makes it gradually widely used in intelligent transportation systems to collect the above-mentioned traffic information. The radar radiates electromagnetic waves and receives the corresponding radar echo signals. The detection a...

Problems solved by technology

The radar radiates electromagnetic waves and receives the corresponding radar echo signals. Through the detection and identification of the radar echo signals, the detection and positioning of the target can be realized. Continuous tracking, but radar detection has its limitations. For example, radar can only perform periodic detection, and it can only detect moving objects and cannot detect stationary objects, so it is prone to missed detection, and the accuracy is relatively low.
