Abstract

The invention discloses an automatic driving system performance evaluation method and device, equipment and a storage medium. The method comprises the following steps of acquiring scene information, wherein the scene information comprises source data used for performing performance evaluation on all functional modules of an automatic driving system; for each functional module, performing performance evaluation on the current functional module according to the source data corresponding to the current functional module and output data of the previous functional module in an evaluation process toobtain a sub-functional performance evaluation result corresponding to the current functional module; obtaining an overall performance evaluation result of the automatic driving system according to each obtained sub-functional performance evaluation result, wherein realization of the function of the current functional module depends on the output data of the previous functional module in the evaluation process. Through the technical scheme, the overall performance evaluation of the automatic driving system is realized, and the overall capability of the automatic driving system can be known according to the evaluation result.

Description

technical field [0001] Embodiments of the present invention relate to automatic driving technology, and in particular to a method, device, device, and storage medium for performance evaluation of an automatic driving system. Background technique [0002] Self-driving cars, also known as self-driving cars, rely on technologies such as artificial intelligence, computer vision, radar, global positioning systems and high-precision maps to automatically obtain environmental information around the vehicle and make decisions and path planning, so as to achieve complete independence from humans. operating autonomous driving. Testing the performance of autonomous driving systems is a key part of ensuring the safety of autonomous vehicles. [0003] At present, the evaluation of the performance of the automatic driving system is mainly to evaluate each functional module in the automatic driving system separately. The major international automatic driving public data sets also evaluate...
