Abstract

The invention provides a mobile robot navigation method based on a two-dimensional code. The method is implemented by a mobile robot equipped with a wheel encoder, a laser rangefinder, a Kinect sensor, an airborne server and an intelligent terminal capable of generating a two-dimensional code. The method comprises the following steps: the airborne server obtains position and posture information data of the laser rangefinder, and constructs and stores a two-dimensional map of the environment; the airborne server transmits the two-dimensional map information to the intelligent terminal to generate a two-dimensional code image; a two-dimensional code image generated by the intelligent terminal is scanned by the kinect sensor to obtain position information in the two-dimensional code image; the mobile robot plans a navigation route according to the position information in the two-dimensional code image and performs autonomous navigation. The invention can simplify and visualize the input mode of the autonomous navigation system, reduce the operation difficulty of the user, be more suitable for the user, and realize the two-dimensional code navigation quickly.

Description

technical field [0001] The invention relates to a mobile robot navigation method, in particular to a mobile robot navigation method based on a two-dimensional code. Background technique [0002] With the rapid development of computer technology, satellite positioning system and Internet technology, composition and positioning technology based on indoor and outdoor environments have been widely used in real life. At present, the problem of map construction and navigation in indoor and outdoor environments has become a hot field. Although the method of building two-dimensional map navigation based on lidar is relatively mature and complete, the method is cumbersome and requires multiple inputs and operations. The position of the target point, and more sensors may be needed for fusion, so the method based on the two-dimensional code navigation under the two-dimensional map has also become popular. [0003] At present, two-dimensional code navigation is popular in indoor and ou...
