Abstract

The invention discloses a positioning accuracy testing scheme of a mobile robot navigation system, comprising the following steps: selecting a test environment, building a SLAM positioning map, selecting a reference point for positioning a mobile robot, measuring a real displacement by a laser range finder, collecting and calculating the measured displacement by a sensor positioning data , Gaussian distribution fitting, positioning accuracy calculation. Compared with the prior art, the present invention has the advantages of low cost, high efficiency, convenient measurement, high precision, multiple applicable scenarios, high reliability, wide coverage area, and low degree of privacy intrusion.

Description

technical field [0001] The invention relates to the technical field of mobile robots, in particular to a positioning accuracy testing method of a navigation system of a mobile robot. Background technique [0002] With the development of science and technology, robots have been widely used all over the world. The research on the key technologies of robots has become a hot topic in science and technology and industry in various countries, and the development of robots has also become an important indicator to measure the level of national science and technology and the advanced level of industrialization. [0003] The repeated positioning accuracy of a mobile robot is the most important and basic performance index. Only by realizing accurate position positioning can other functions of the robot be expanded. For different scenarios, the positioning accuracy requirements of the robot are different. Indoor is the scene where mobile robots are most used. Nowadays, indoor service...
