FLOOR SWEEPING ROBOT AND POSITIONING METHOD FOR FLOOR SWEEPING ROBOT

摘要

Provided are a floor sweeping robot, and a positioning method for the floor sweeping robot, the floor sweeping robot being provided with a visual positioning system, and the positioning method comprising: positioning the floor sweeping robot by means of the visual positioning system to obtain first position information (S1); acquiring a magnetic field fingerprint at a position where the floor sweeping robot is currently located (S2); searching for second position information corresponding to the magnetic field fingerprint in a magnetic field map (S3); if the first position information is the same as the second position information, determining that the first position information is correct position information (S5); and if the first position information is different from the second position information, or no second position information corresponding to the magnetic field fingerprint is found, carrying out repositioning by means of the visual positioning system to obtain third position information, and setting the third position information to be current position information (S4). The positioning method can improve the positioning accuracy of the floor sweeping robot, and can reduce the probability of mismatching during visual repositioning in a similar environment; and the magnetic field map is autonomously created, and can be updated in real time.
