MAP CREATION METHOD FOR MOBILE ROBOT AND PATH PLANNING METHOD BASED ON THE MAP

摘要

The present disclosure discloses a map creation method of a mobile robot, including establishing a rectangular coordinate system in a working area of the mobile robot; causing the mobile robot moving in a character shape in the working area; obtaining a key frame picture of the mobile robot at a point Pi and saving the picture and coordinates of the point Pi; obtaining a picture of the mobile robot at a point P′i, wherein an abscissa or ordinate of the point P′i is the same as that of the point Pi; extracting and matching features of the pictures acquired at the point Pi and the point P′i; calibrating coordinates of the mobile robot at the point P′i and data of the odometer and/or the gyroscope according to the matching result and saving them; and repeating the obtaining to the calibrating until the map creation in the working area is complete.
