Scene classification method and device for automatic driving vehicle road testing

Abstract

The invention provides a scene classification method and device for automatic driving vehicle road testing. The method comprises the following steps: determining one or more pre-created road scenes and scene composition elements of the road scenes, and dividing the scene composition elements into a first composition element and a second composition element; calculating to obtain a first score according to the information amount contained in the first component element and a preset score corresponding to each scene component element; in a real scene test or a simulated scene test of the vehicle, obtaining test information generated by each scene component element and each scene component element in the second component elements, and inputting the test information into a predetermined modelstructure to obtain a second score; and calculating to obtain a third score according to the first score and the second score so as to realize classification of the road scene based on the third score. According to the invention, the complexity of dividing different types of road scenes is realized, and the test efficiency and the evaluation effect of the automatic driving vehicle are improved.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle testing, and in particular to a scene classification method and device for road testing of autonomous vehicles. Background technique [0002] With the development of society, the means of transportation are gradually developing in the direction of diversification and intelligence. In the process of vehicle design and production, vehicle testing is one of the very important links. Taking self-driving vehicles (such as smart cars, driverless cars, intelligent networked vehicles, etc.) important. Road testing of self-driving vehicles can not only test and verify new technologies, promote the development of technology, but also verify the safety of self-driving vehicles through testing. [0003] The vehicle testing method based on the road scene is the current mainstream vehicle testing method. For example, the pre-crash scenarios of the U.S. Highway Traffic Safety Administration (NHTSA),...
