Abstract

The present application relates to a method, a device, a computer device and a storage medium for marking guide points for visual navigation. The method includes: determining the first target point in the first image according to preset rules by acquiring sequential image information obtained from the environment when the unmanned vehicle is driving, and calculating the obtained by image feature matching and affine coordinate transformation The target point in the first image is projected to the second target point in the second image as the guide point of the second image. According to the guide point, the control strategy when no one is autonomously navigating in this scene can be obtained. The method can automatically generate a series of guide points corresponding to images, avoid manual marking, and has the advantages of high efficiency and good consistency.

Description

technical field [0001] The present application relates to the technical field of unmanned driving, and in particular to a method, device, computer equipment and storage medium for marking guide points for visual navigation. Background technique [0002] As an emerging technology combining artificial intelligence and automation technology, unmanned driving technology has gradually become an important driving force to promote the upgrading of the automobile industry and the penetration of robot technology into ordinary people's homes. At the same time, unmanned driving technology has many important applications in important fields such as aerospace and navigation. [0003] The guide point is the position that the unmanned vehicle is expected to reach at some point in the future when controlling the unmanned vehicle. The preview control method based on the guide point is to calculate the control strategy of the next behavior of the unmanned vehicle according to the position of...
