Door region identification method, door region identification system and cleaning robot

Abstract

The invention provides a door region identification method, a door region identification system and a cleaning robot. Through obtaining a raster map in the home environment, an irrelevant region and aregion to be treated are obtained by segmenting the raster map, then the characteristic value of the region to be treated is obtained to obtain a first region and a second region, region separated signs are conducted, preset parameters of a door region are obtained, matching modules are generated according to the preset parameters, and finally, a whole scan is conducted by using the matching modules and the signs to identify the door region. According to the door region identification method, the door region identification system and the cleaning robot, through optimizing internal arithmetic,without the help of virtual wall equipment, the mobile robot can use the characteristic value of the door region to match data, finally, the position of the door region is identified through the matching modules, region separated cleaning can be conducted by the mobile robot through taking the position of the door region as a boundary, the region separated cleaning autonomously is achieved, the manufacture cost is saved, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of mapping, in particular to a door area identification method, a door area identification system and a cleaning robot. Background technique [0002] In the existing technology, the first thing for a robot to realize autonomous movement indoors is to establish a map of the indoor environment and determine the current position of the robot. Slam technology is synchronous positioning and mapping, which is currently a relatively popular mapping technology in the field of robotics at home and abroad. In the Slam technology, the robot uses its own laser radar sensor to perceive the surrounding environment, obtains the feature marks in the environment, and uses the relative position relationship between the feature marks and the robot to establish the global coordinates, and then the robot realizes autonomous movement and cleaning. However, the user's demand for the sweeping robot is getting higher and higher. The...

Problems solved by technology

However, the user's demand for the sweeping robot is getting higher and higher. The user hopes that the sweeping robot can clean in different areas, and the next area will be cleaned after completing the cleaning task in the designated area. The virtual wall device enables the sweeping robot to perform partition cleaning with the virtual wall as the boundary. Although this solution directly achieves the effect expected by the user, it needs to add an additional virtual wall device, which undoubtedly requires more investment in costs and materials. Therefore, the existing laser mapping technology has defects and needs to be further improved
