Abstract

The invention relates to the technical field of sensor data processing, in particular to an environmental perception method based on machine vision and millimeter wave radar data fusion. The method comprises a data acquisition step of acquiring the data of a radar system and a vision system; a data association matching step of obtaining the target object data lists detected by the two sensing systems, and performing matching association on the target object data detected by the two sensing systems; a target object tracking step of performing matching tracking on the target object, and updatingthe life cycle state of the target object; and a target object data fusion step of fusing the data signals of the target object outputted by the radar system and the visual system. According to the environment sensing method based on machine vision and millimeter wave radar data fusion, the advantages and disadvantages of two sensing systems of a vision system and a radar system can be fused to achieve the purpose of accurately sensing environment information, and the problem that a single-characteristic sensor is difficult to meet the precision and reliability requirements of a sensing system is solved.
