Abstract

The application relates to a robot positioning method and device and electronic equipment. The method comprises the steps: determining a first residual item through matching of a laser point cloud anda grid map through the obtaining of the laser point cloud and the grid map of a robot; determining a detection position of a reflective column according to the laser point cloud, and matching the detection position with the calibration position of the reflective column to determine a second residual term; determining the maximum and minimum values of the first residual term and the maximum and minimum values of the second residual term by using nonlinear optimization; determining a frame pose of laser equipment according to the maximum and minimum values; and determining the pose of the robotaccording to the frame pose. Therefore, a problem that the pose precision of the robot obtained after fusion is low when the deviation of observation information or prediction information is large due to the fact that filtering fusion is conducted on the pose matched with the contour and the pose matched with the light reflection column based on a filtering mode is solved, and the positioning precision of the robot is improved.

Description

technical field [0001] The present application relates to the technical field of positioning and navigation, in particular to a positioning method, device and electronic equipment for a robot. Background technique [0002] At present, automatic guided transport vehicles are booming, and various guided transport vehicles such as logistics robots, guide robots and home robots have emerged on the market. In the entire robot system, navigation technology is one of its most important core technologies. Navigation technology mainly determines the current pose information of the robot through sensor technology, and clarifies the guidance angle, speed and running route of the car according to the destination information. [0003] In the related technology, the odometer measurement value is used to estimate the pose of the mobile robot in real time during the mapping process. The pose of the robot is calculated by matching the contour with the map during the navigation process, and t...
