Embodiment Construction

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0051] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication also changes accordingly.

[0052] In addition, the desc...

Abstract

The invention provides a road planning method and device and a computer readable storage medium. The road planning method comprises the following steps of acquiring a left lane line and a right lane line, calculating and generating a road center line according to the left lane line and the right lane line, obtaining a vehicle driving trajectory, and calculating a planned path according to the trajectory and the road center line. According to the technical scheme, the single camera is used for collecting and transmitting the information of the left lane line and the right lane line on the two sides of the vehicle, then the left lane line and the right lane line are combined with the automatic driving or auxiliary driving trajectory of the vehicle for path planning, and the planned path is generated and provided for a driving system of the vehicle to control the vehicle. Therefore, the method does not depend on additional hardware equipment, only depends on the camera to plan the future driving trajectory of the vehicle, reduces the research and development cost of a product, and improves the competitiveness of the product.

Description

technical field [0001] The present invention relates to the technical field of intelligent driving, in particular to a road planning method, device and computer-readable storage medium. Background technique [0002] At present, on vehicles equipped with intelligent assisted driving systems at home and abroad, it is usually necessary to control the vehicle to move from the current position deviating from the target trajectory to the target trajectory. The commonly used technical solutions include using a variety of sensors to model the surrounding environment, and then using a local path planning algorithm for path planning, so as to control the vehicle to drive to the target trajectory. However, in the existing technology, in order to realize the automatic planning of the path, it is necessary to carry a variety of sensors on the vehicle, such as ultrasonic radar, millimeter wave radar, laser radar, surround view camera, etc.; and the requirements for chip computing power ar...
