The application provides an information processing method and device and electronic equipment with an SLAM (Simultaneous Localization And Mapping) function. The information processing method comprises the following steps: building a closed-loop map according to a preset model and storing path information in the map building process; after building of the closed-loop map, according to preset map optimization rules and the stored path information, optimizing the map. By the adoption of the method, as the path information in the map building process, correct information in the building process cannot be filtered; after completion of the closed-loop map, the map is optimized according to the map optimization rules and the path information, in the map optimizing process, and the map can be optimized according to the correct information in the information stored in the map building process, so that the error rate of the map is reduced, and the finally built map is low in error and relatively high in accuracy. The application further provides the electronic equipment applying the information processing device.
Description
technical field [0001] The present invention relates to the field of electronic equipment, and more specifically, relates to an information processing method, device and electronic equipment. Background technique [0002] Robot simultaneous localization and map construction (simultaneous localization and mapping, SLAM) technology is a key issue in robot navigation technology. [0003] In the prior art, the SLAM of the robot is generally realized by using GMapping. [0004] GMapping is a robot positioning technology with particle filter as the core, and uses the method of sprinkling particles to construct maps. During the construction process, the particles that do not meet the weight conditions are deleted as wrong pose particles, and the particles that meet the weight conditions are retained as correct pose particles. If there is a deviation in the weight estimation of the particles, the real correct pose particles will be deleted, and the map will be constructed based on...
