Problems solved by technology

[0003] However, since there are many objects in the real world that cannot reflect light, robots based on laser sensor navigation can only be used in specific scenarios
For example, when the laser emitted by the robot encounters an escalator made of glass, the laser will directly penetrate the glass without returning, causing the robot's navigation and positioning function to fail

Abstract

The invention is applicable to the technical field of robot navigation, and provides a positioning method and positioning device of a mobile robot, the mobile robot and a computer readable storage medium. The method comprises the steps that an image collected by the mobile robot is input into a trained convolutional neural network for target detection; if it is determined that the image contains atarget object based on a result of the target detection, a target frame of a target object is obtained in the image; the height of the target frame is calculated according to the pixel coordinates ofthe target frame; and a target distance is calculated according to the height of the target frame, a preset focal length and a preset height of the target object. By means of the method, the mobile robot can accurately navigate and position in various scenes.

Description

technical field [0001] The present application belongs to the technical field of robot navigation, and in particular relates to a mobile robot positioning method, a positioning device, a mobile robot and a computer-readable storage medium. Background technique [0002] Robot navigation technology has always been a research hotspot in the field of robotics. Through navigation technology, the robot can locate its own position. Existing robots based on laser sensor navigation rely on laser radar to emit a beam of light in a specific direction during autonomous movement. This beam of light will bounce back after encountering an object and be received by a receiving device on the robot. Since the speed of light is known, the distance between the robot and the object can be deduced by calculating the time interval between the light emitted by the lidar and the light received by the receiving device. [0003] However, since there are many objects in the real world that cannot ref...
