Abstract

The invention discloses an object recognition method and device for an automatic driving vehicle. The invention relates to the technical field of automatic driving and solves the problem that it is difficult for existing automatic driving vehicles to accurately identify obstacles. The present invention uses video to identify object appearance data, uses high-precision imaging radar hybrid detection as a secondary supplement for object appearance data detection, and uses high-precision imaging radar to accurately measure distances to form projections of multiple data types in one space, which is truly realized The classification of objects and targets in the 3D view in autonomous driving, and the realization of the distance, do not rely on the assumption of "flat ground", but through radar or lidar data, and only need to use the data of a camera to project the radar data to the reconstructed by video acquisition data In the 3D model of the 3D model, the classification of objects and targets in the 3D view is actually realized, and the precise distance between the self-driving vehicle and each type of target is distinguished.

Description

technical field [0001] The present invention relates to the technical field of automatic driving, in particular to an object recognition method and device for automatic driving vehicles. 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 identify objects and mea...
