Abstract

The embodiment of the invention discloses a performance analysis method and device for a vehicle-mounted millimeter wave radar, a terminal and a storage medium. The method comprises the following steps of receiving obstacle data determined by a millimeter wave radar and real video data of an obstacle acquired by an image acquisition device, generating obstacle detection video data according to theobstacle data based on the receiving time sequence of the obstacle data and the visualization mode corresponding to the classification of the obstacle data, and performing comparative analysis on thedetection video data and the real video data, and determining the detection performance of the millimeter wave radar according to an analysis result. Obstacle data sensed by the millimeter wave radarcan be analyzed, expandability is good, and development and use are convenient.

Description

technical field [0001] Embodiments of the present invention relate to the field of driving assistance, and in particular to a performance analysis method, device, terminal and storage medium of a vehicle-mounted millimeter-wave radar. Background technique [0002] With the popularity of automobiles, the problem of traffic pressure is increasing day by day, and the safety accidents caused by driver negligence are also on the rise. The safety of automobiles has become a topic of concern to people. [0003] Cars equipped with advanced driver assistant systems (Advanced Driver Assistant System, ADAS) are becoming more and more popular, and the key to developing advanced driver assistant systems lies in the perception ability of sensors, which directly determines the quality of the car. The quality of ADAS features is good or bad. As the most common and low-cost sensor for automotive ADAS functions, millimeter-wave radar is increasingly favored by various automobile manufacturer...
