Abstract

The invention provides a driver assistance system and method based on a millimetre-wave radar, a terminal and a storage medium. The driver assistance system based on the millimetre-wave radar comprises at least one millimetre-wave (mmW) transceiver (Tx / Rx), an original data processing unit, a dynamic and static separation unit, a fusion unit, an analysis unit and a decision-making unit. The driverassistance system based on the millimetre-wave radar in the invention does not depend on a visual sensor; point cloud data singly obtained by the millimetre-wave radar is subjected to pre-processing,fusion, dynamic and static separation, individual semantic acquisition, tracking and analysis; therefore, the effect having the same target obtained by image processing through the visual sensor canbe achieved; furthermore, fusion between visual perception data and radar perception data can be utilized in the invention; then, processing or analysis is carried out; for target object tracking, therelative distance, speed and angle data are relatively precise in the invention; and thus, the driver assistance system disclosed by the invention is more suitable for being used in complex scenes having relatively high people flow, such as a parking lot, a garden and a basement.

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 ...
