Positioning Method for Ceiling Vision Robot

Abstract

A positioning method for a ceiling vision robot are provided. The method includes: during a moving process, a ceiling vision robot acquiring a ceiling image in real time; acquiring existing road sign distribution information according to the ceiling image; determining whether to establish a new road sign, according to the existing road sign distribution information, and if so, establishing a new road sign at a acquisition position of the ceiling image, and if not, not establishing the new road sign at the acquisition position of the ceiling image; and monitoring the positioning effectiveness of an existing road sign according to the existing road sign distribution information, and if the positioning of the existing road sign is effective, performing positioning by using pose information corresponding to the existing road sign, and if the positioning of the existing road sign is ineffective, not performing positioning by using the pose information corresponding to the existing road sign. In the method, a ceiling vision robot is used to avoid a situation in which the environment is complex and road signs are thus easily confused; a new road sign is established according to existing road sign distribution information, thereby realizing the uniformly establishment of road signs; and effectiveness detection is performed on an existing-road sign, thereby improving the precision of positioning based on road signs.
