Problems solved by technology

[0003] When the legged robot performs real-time positioning, it adopts the method of using the legged odometer for real-time positioning, but the real-time positioning obtained by the legged odometer is relatively difficult due to the influence of air resistance, ground friction and other factors when the robot is applied. Large error, insufficient positioning accuracy

Abstract

The invention discloses a robot positioning method and a device thereof, a storage medium and a robot, the robot comprises a foot type speedometer and a single-line laser radar, the method comprises the following steps: obtaining pose information collected by a foot type speedometer at a previous timestamp, and obtaining point cloud data collected by the single-line laser radar at a current timestamp, calculating an expected position of the current timestamp in a world coordinate system based on the pose information collected at the previous timestamp, and mapping the point cloud data collected at the current timestamp and the expected position of the current timestamp to the world coordinate system to obtain a transformation matrix; and calculating an actual position of the current timestamp under the world coordinates based on the transformation matrix and the expected position. By adopting the embodiment of the invention, the accuracy of real-time positioning of the robot can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a robot positioning method, device, storage medium and robot. Background technique [0002] With the development of artificial intelligence technology, the research and development of mobile robots is very rapid. When the robot is performing tasks, in order to ensure the position of the robot or prevent the loss of the robot, it is necessary to locate the robot in real time. [0003] When the legged robot performs real-time positioning, it adopts the method of using the legged odometer for real-time positioning, but the real-time positioning obtained by the legged odometer is relatively difficult due to the influence of air resistance, ground friction and other factors when the robot is applied. Large error, insufficient positioning accuracy. Contents of the invention [0004] Embodiments of the present application provide a robot positioning method, device, storag...
