Embodiment approach

[0130] In some of the above embodiments, the operation of using the depth camera of the robot to collect the depth image data of at least one object around the robot is included. An optional implementation of this operation includes:

[0131] First, use the depth camera to capture the scene around the robot to obtain color images and depth images; color images are mainly used for object detection and tracking, and each pixel in the depth image has distance information in the three axes of X, Y, and Z, namely pixel coordinates. Among them, the X axis, Y axis and Z axis are the coordinate axes in the three-dimensional coordinate system where the robot is located, the directions of the X axis and the Y axis are two directions on the horizontal plane where the robot is located, and the direction of the Z axis is along the longitudinal direction of the robot. Wherein, the range of surrounding scenes may be determined by the visual range of the depth camera.

[0132]Secondly, base...

Abstract

The embodiment of the invention provides a positioning method, device and system based on a robot and a storage medium. According to the invention, the invention provides a robot including a distancecommunication module; the robot also comprises a depth camera and / or a laser radar; when the robot positions a target object, a near-distance communication module of the robot can be combined with thedepth camera and / or the laser radar of the robot; advantages of the near-distance communication module, and the depth camera and / or the laser radar are fully used; and by fusing various information,the target object is positioned, so reduction of positioning errors is facilitated and positioning precision is improved.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, and in particular to a robot-based positioning method, device, system and storage medium. Background technique [0002] With the development of artificial intelligence technology, the research and development of mobile robots is very rapid, and some service robots have gradually entered people's daily life. Based on the robot following technology, service robots can perform some following tasks, such as escorting customers, welcoming guests, etc. Robot following technology means that the robot keeps a certain distance and speed to follow the target object, and assists the target object to complete related social production activities. [0003] In the robot following technology, the relative positioning between the robot and the target object is the primary problem to be solved. In the existing robot following technology, a triangulation algorithm based on WiFi and Blue...
