Abstract

The invention discloses a path planning information acquisition method, a path planning method and electronic equipment. The method comprises the following steps: acquiring a reference path; according to the environment information of the reference path, obtaining multiple longitudinal sampling points on the reference path, wherein the multiple longitudinal sampling points are adapted to environment information distribution; and collecting a plurality of transverse sampling points on the left side and / or the right side of the plurality of longitudinal sampling points for path planning. According to the method, the sampling points are acquired in combination with the environment information, so that the acquired sampling points are more suitable for the actually detected external environment, and a path conforming to the actual external environment can be planned.

Description

technical field [0001] The present invention relates to the technical field of automatic driving, in particular to a path planning information collection method, a path planning method and electronic equipment. Background technique [0002] With the development of artificial intelligence technology, autonomous driving technology is becoming more and more mature. Autonomous driving technology can be briefly divided into perception, prediction, positioning, decision-making, planning and control. Planning usually refers to the path planning method. The main task is to reasonably explore the environment space according to the current vehicle information, and finally plan a path that is easy for the controller to execute and has no collision. [0003] Dynamic programming algorithm is one of the most common path planning methods in the field of autonomous driving. The input required by the dynamic programming algorithm includes reference paths and environmental information. The...
