Problems solved by technology

[0003] Since there are large environmental targets (such as large trucks) in the road environment, its length and width are very large, so it cannot be represented by a center point attribute of the target, which will result in poor lateral and longitudinal control effects of the vehicle, and serious cause traffic accident

Abstract

Embodiments of the present invention provide a method and device for extracting feature points of environmental objects, which belong to the field of vehicles. The method includes: obtaining the position of each corner point of the environmental object; and determining the feature point of the environmental object according to the position of each corner point of the environmental object. It can solve the problem of imprecise target recognition, and is especially suitable for the recognition of larger targets (for example, trucks, etc.).

Description

technical field [0001] The present invention relates to the field of vehicles, in particular to a method and device for extracting feature points of environmental objects. Background technique [0002] During the driving process, the self-driving vehicle needs to use the sensors installed on the vehicle body to obtain the information of the surrounding environment targets, and combine the surrounding environment lane line information to divide the target area, so as to further obtain the area attributes of the target. Targets in different areas can be used for longitudinal control and lane change decisions, while lane line information can provide vehicles with driving path information for lateral control for lane change and lane keeping. [0003] Since there are large environmental targets (such as large trucks) in the road environment, their length and width are very large, so they cannot be represented by a center point attribute of the target, which will result in poor la...
