Abstract

The invention discloses a system and method for establishing a map by taking photos to recognize the floor through a mobile phone, and relates to the field sweeping map systems. The system comprises amobile phone processing unit, a connecting end of the mobile phone processing unit is provided with a mobile phone camera, a gyroscope and a gradienter, an output end of the mobile phone processing unit is provided with an image processing module and a verification calculation module, an output end of the image processing module is provided with an image assembling module, an output end of the image assembling module is provided with a dimension calculation planning module, and the dimension calculation planning module is connected with the mobile phone processing unit. According to the system, indoor scenes are photographed through a mobile phone camera through a mobile phone APP, 3D conversion is conducted on a planar image by the image processing module using the gradienter and the gyroscope to establish a planar map, map data is transmitted to a floor sweeping robot and saved by the robot after the map is received, and efficient navigation is conducted by the floor sweeping robotthrough the map to clean the floor.

Description

technical field [0001] The present invention relates to the technical field of cleaning map system, and more specifically, the present invention relates to a system and method for establishing a map by taking pictures of mobile phones to identify floors. Background technique [0002] At present, sweeping robots generally use infrared sensors or other distance measuring sensors to perform obstacle avoidance cleaning, which leads to the blindness of the robot when it is used, many positions cannot be cleaned, and the cleaning efficiency is poor. [0003] Existing indoor map generation generally uses laser scanning equipment to generate maps, but the cost is high and it is inconvenient to use. Contents of the invention [0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide a system and method for establishing a map by taking pictures of the mobile phone to identify the floor. The indoor scene is shot throug...
