Abstract

The embodiment of the invention provides a high-speed automatic driving scene obstacle perception evaluation method and device. The method comprises the steps of processing a road test image according to a visual perception algorithm to obtain the algorithm output data, wherein the algorithm output data comprises the position and the type of a first obstacle, and the road test image is acquired when an autonomous vehicle runs on a road; carrying out marking processing on the obstacle in the drive test image to obtain true value marking data, the true value marking data comprising the position and the type of a second obstacle; and performing obstacle matching according to the algorithm output data and the true value annotation data to obtain an evaluation result of the visual perception algorithm. According to the high-speed automatic driving scene obstacle perception evaluation method and device provided by the embodiment of the invention, the problems that an existing obstacle perception evaluation method is high in road test cost and a certain danger exists in the actual road test, can be solved.

Description

technical field [0001] Embodiments of the present invention relate to the field of automatic driving, in particular to a method and device for evaluating obstacle perception in a high-speed automatic driving scene. Background technique [0002] Self-driving cars, also known as unmanned cars, are unmanned intelligent vehicles driven by a comprehensive perception system and controlled by computer software. It is an important part of the future intelligent transportation, has a very bright prospect, and is one of the hot research topics in the field of vehicle engineering. [0003] In the field of autonomous driving, visual perception of obstacles has an important impact on the driving decisions of unmanned vehicles. In the specific implementation process, the image information is collected through the camera, and then the image information is processed by an algorithm to output the visual perception obstacles of the autonomous driving scene, and then the information fusion of...
