Abstract

The embodiment of the invention discloses a method and a device for controlling a vehicle. A specific embodiment of the method comprises the steps of obtaining first point cloud data collected by a vehicle in a driving process; identifying an obstacle in the first point cloud data; determining second point cloud data according to the first point cloud data and the identified point cloud data corresponding to the obstacle; clustering the second point cloud data, and determining at least one obstacle corresponding to the second point cloud data according to a clustering result; and according to the determined at least one obstacle, sending a control signal to the vehicle to control the vehicle. According to the method, the point cloud data corresponding to the unknown type of obstacle can be further processed so as to guide the vehicle to run more reasonably.

Description

technical field [0001] The embodiments of the present application relate to the technical field of vehicle control, and in particular to a method and device for controlling a vehicle. Background technique [0002] The use of depth sensors and position and attitude sensors to collect 3D information of the surrounding environment based on fixed stations or mobile platforms is widely used due to its high efficiency, real-time, and high-precision characteristics. Since the scanned scene contains different types of objects, such as ground, buildings, trees, vehicles, etc. The point cloud data corresponding to different types of objects needs to be separated from each other through point cloud segmentation, so that point cloud modeling can be performed on each object separately. If these obstacles are close or overlapped, existing point cloud segmentation schemes can easily identify multiple obstacles as one large obstacle. Such recognition results can affect the driving of auto...
