Abstract

The invention discloses a navigation method and device, electronic equipment and a computer readable storage medium. The method comprises the steps of: determining a world coordinate system based on an ArUco code in a target environment, and building a three-dimensional point cloud picture corresponding to the target environment according to the three-dimensional coordinate of each ORB feature point in the world coordinate system, wherein the plurality of ArUco codes are distributed at any position of a target environment; acquiring a current image acquired by image acquisition equipment, and determining an absolute pose of the image acquisition equipment in the world coordinate system according to the ORB feature points in the current image; and acquiring a navigation path, determining a target ORB feature point belonging to the navigation path in the current image, and performing navigation based on the current three-dimensional coordinate of the image acquisition equipment in the world coordinate system, the absolute pose and the three-dimensional coordinate of the target ORB feature point. According to the navigation method provided by the invention, stable and reliable autonomous positioning and navigation can be realized, and the environmental dependence of navigation can be reduced.

Description

technical field [0001] The present application relates to the technical field of navigation, and more specifically, to a navigation method, device, electronic equipment, and computer-readable storage medium. Background technique [0002] The visual positioning and navigation method using image acquisition equipment as the main sensor is an important method for mobile platform equipment such as mobile robots and drones to achieve autonomous positioning and navigation. The image data captured by the image acquisition device contains rich scene information. Through image processing and computer vision technology, the real-time pose estimation of the image acquisition device in three-dimensional space can be realized, thereby providing accurate position and orientation information for the mobile platform. [0003] In related technologies, guide lines of different colors are laid on the ground, ground beacons such as barcodes or QR codes are laid out, and positioning and navigati...
