Holographic intersection sensing method based on multi-source sensor

Abstract

The invention discloses a holographic intersection sensing method based on a multi-source sensor, and the method comprises the following steps: 1, obtaining target data detected by a radar and a video at the same time, wherein the target information detected by the radar comprises the target intensity, the position information and the speed information, the position information comprises the slant distance and the azimuth angle, the target information detected by the video comprises a target type, position information and the height and width of pixels occupied by the target, and the position information comprises the center position of the pixel where the target is located; 2, converting coordinates of position information in the radar target and the video target; and 3, generating and updating a target track by using the target position information which is subjected to coordinate conversion and detected by the radar and the video respectively. Compared with the prior art, the method has the advantages that the problem that a single video sensor is insufficient in sensing capacity due to target shielding, capacity limitation and the like is solved.

Description

technical field [0001] The invention relates to the technical field of Internet of Vehicles, in particular to a multi-source sensor-based holographic intersection perception method. Background technique [0002] In modern urban construction, with the popularization of automobiles, incidents such as traffic jams, illegal parking, and running red lights often occur, and intersections have become high-incidence areas. At present, the technology often used for intersection monitoring is camera detection. The camera has the characteristics of high resolution, flexible station layout, and intuitive target information acquisition. However, it cannot work normally at night and is easily affected by weather such as rain and fog. Radar equipment has the advantages of wide detection range, flexible target tracking, good weather adaptability, and high positioning accuracy. [0003] With the diversified development of detection technology, making full use of various existing detection m...
