Method and device for determining local planning path

Abstract

The invention discloses a method and a device for determining a local planning path. The method and the device are used for solving a problem that the local planning path of automatic driving is not smooth in the prior art. The method comprises the following steps: firstly, taking the current position of a target vehicle as a start point, and according to coordinates information of a plurality ofpreset position points in preset distance on a preset planning path, determining the coordinates information of at least one other position point, except for the preset position points, on the presetplanning path; further determining planning point coordinates information corresponding to the preset position point according to the coordinates information of the preset position point and positionoffset corresponding to the preset position point; according to the coordinates information of the other position points and the position offset corresponding to the other position points, determiningthe planning point coordinates information corresponding to the other position points; and finally, fitting the planning point coordinates information to form the local planning path. Since the planning point coordinates corresponding to the plurality of preset position points ant at least one other position point are fitted to form the local planning path, the local planning path is more smooth.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to a method and equipment for determining a local planning path. Background technique [0002] With the continuous development of artificial intelligence, self-driving cars have gradually entered people's lives, bringing great convenience to people's lives. [0003] Self-driving cars are a type of smart cars, also known as wheeled mobile robots, which mainly rely on the computer system-based smart driver in the car to achieve the purpose of automatic driving. [0004] Self-driving cars can perceive the road environment through the on-board sensing system, automatically plan driving routes and control the smart cars to reach the predetermined target. It can use on-board sensors to perceive the surrounding environment of the vehicle, and control the steering and speed of the vehicle according to the road, vehicle position and obstacle information obtained by the perce...
