Abstract

The invention discloses a method and a device for object recognition and distance measurement of an automatic driving vehicle, and relates to the technical field of automatic driving. The problem thata conventional automatic driving vehicle is difficult to achieve the accurate recognition of an obstacle and the distance measurement at the same time is solved. Object appearance data is identifiedby using a video, mixed detection of a high-precision imaging radar is used as secondary supplement of object appearance data detection, accurate distance measurement of the high-precision imaging radar is utilized to form projection of multiple data types in one space, object target classification of a 3D view in automatic driving is truly realized, and distance measurement is achieved; and the radar data is projected to a 3D model reconstructed by video acquisition data through radar or laser radar data without depending on the assumption of 'ground flatness', so that object target classification in the 3D view is truly realized, and the accurate distance between the automatic driving vehicle and each type of target is distinguished.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to an object recognition and distance measurement method and device for an automatic driving vehicle. Background technique [0002] In the L3~L5 autonomous driving technology, accurately judging the distance between the autonomous vehicle and each target is crucial to the driving process of the autonomous vehicle. In humans, we possess two high-resolution and highly synchronized visual sensors, our eyes. Through the brain's stereopsis processing, our eyes are able to measure distance. However, in self-driving vehicles, it is very difficult to use binocular cameras to simulate human eyes for visual distance measurement, because the high-precision synchronization of binocular cameras is difficult to solve, which will lead to distance estimation errors. [0003] Therefore, in the current autonomous driving technology, the data of the monocular camera is mostly used to ident...
