Abstract

The embodiment of the invention discloses a positioning method and device, electronic equipment and a storage medium. The method comprises the following steps: for two omnidirectional wheels, acquiring the driving distance of the omnidirectional wheels through an encoder, and acquiring the correction distance of the omnidirectional wheels through a distance measurement gyroscope; the rotation angle of the to-be-positioned object is obtained through the angle measurement gyroscope; for the driving distance and the correction distance of each omnidirectional wheel, processing the driving distance and the correction distance of each omnidirectional wheel to obtain a processing result; obtaining target position information of the to-be-positioned object based on the rotation angle and the two processing results; wherein the two omnidirectional wheels are orthogonally arranged and serve as driven wheels of the object to be positioned, a main rotating shaft of each omnidirectional wheel is coaxially connected with a rotating shaft of the encoder, a rotating shaft of the distance measurement gyroscope is coaxially connected with the main rotating shafts of the omnidirectional wheels, and the angle measurement gyroscope is located at the intersection position of the two omnidirectional wheels and is vertically arranged. According to the scheme, the positioning accuracy is improved.

Description

technical field [0001] The present invention relates to the technical field of positioning systems, and in particular, to a positioning method, device, electronic device and storage medium.
