Abstract

The invention discloses a method for obtaining a navigation map of a working environment of a mobile robot, and the method comprises the steps: obtaining a two-dimensional topological environment mapof the working environment for the working environment where the mobile robot is located, wherein the two-dimensional topological environment map comprises the barrier-free region information under the working environment; acquiring a navigation map of the working environment of the mobile robot according to the two-dimensional topological environment map; and acquiring a navigation map of the working environment on the basis of the two-dimensional topological map containing the barrier-free area information of the mobile robot in the working environment. A more accurate navigation map containing three-dimensional obstacle avoidance information can be provided for the mobile robot.

Description

technical field [0001] The present application relates to the field of navigation, in particular to a method for acquiring a navigation map of a mobile robot working environment. The present application also relates to a navigation method and system for a mobile robot. Background technique [0002] In daily life, the common mobile robot navigation algorithm is mainly to plan the path point set from the current position to the target position on the two-dimensional grid map, and then calculate the real-time speed of the mobile robot through the dynamic window method (Dynamic Window Approach), to ensure The robot reaches the target position safely and accurately. [0003] In the process of mobile robot navigation and driving, the sensors used for ranging mainly include laser radar and depth camera, etc. Generally speaking, the ranging accuracy of laser radar is relatively higher than that of depth camera, and laser radar is divided into multi-line laser Radar and single-line...
