Abstract

The present invention provides a millimeter wave radar-based assisted driving system, method, terminal and storage medium, including: at least one millimeter wave (mmW) transceiver (Tx / Rx), a raw data processing unit, a dynamic and static separation unit, a fusion unit, The analysis unit and the decision-making unit can be invented without relying on the visual sensor, and the point cloud data obtained by the millimeter-wave radar can be used for preprocessing, fusion, dynamic and static separation, individual semantic acquisition, tracking, and analysis, which can achieve the same goal as the visual sensor processing image. effect, the present invention can also use the fusion of visual perception data and radar perception data, and then process or analyze; the present invention is more accurate in relative distance, speed, and angle data when tracking target objects, and is more suitable for complex scenes such as human traffic It is used in larger parking lots, parks, basements and other environments.

Description

technical field [0001] The present invention relates to the technical field of automotive electronics, in particular to a millimeter-wave radar-based assisted driving system, method, terminal and medium. Background technique [0002] Assisted driving technology is now becoming more and more mature. Judging from the current technology, the commonly used sensing devices in Advanced Driver Assistance System (ADAS) and unmanned driving systems are visual sensing devices, ultrasonic radar, and lidar. [0003] The reason why the camera is used as a perception device is that the resolution of the camera is higher than that of other sensors, and it can obtain enough environmental details to help the vehicle recognize the environment. The on-board camera can describe the appearance and shape of objects, read signs, etc. The limitations of visual perception equipment are: it is impossible to accurately detect the distance of objects, it is greatly affected by light, and poor light is ...
