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

Embodiment Construction

[0031] The specific implementation manners of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific implementations described here are only used to illustrate and explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention.

[0032] figure 1 A schematic flowchart of a method for extracting feature points of an environmental target according to an embodiment of the present invention is shown. Such as figure 1 As shown, the embodiment of the present invention provides a method for extracting feature points of an environmental target. The method can be applied to any vehicle, for example, it can be applied to an automatic driving vehicle. The method may include: step S110, acquiring the position of each corner point of the environmental target; and step S120, determining the characteristic point of the environmental targ...

Abstract

The embodiment of the invention provides a method and device for extracting feature points of an environment target, and belongs to the field of vehicles. The method comprises: acquiring the positionof each corner point of the environment target; and determining a feature point of the environmental target according to the position of each corner point of the environmental target. The method and device can solve the problem of inaccurate target recognition, and are particularly suitable for recognition of large targets (such as trucks and the like).

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 targets. Background technique [0002] Autonomous vehicles need to use sensors installed on the vehicle body to obtain information about targets in the surrounding environment during driving, and combine the information of lane lines in the surrounding environment to divide the target area to further obtain the regional attributes of the target. Targets in different areas can be used for longitudinal control and lane changing decisions. At the same time, lane line information can provide driving path information for vehicles for lateral control for lane changing and lane keeping. [0003] Because there are large environmental targets (such as large trucks, etc.) in the road environment, its length and width are very large, so it cannot be represented by a central point attribute of the target, which will cause poor vehicl...
