Embodiment Construction

[0064] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0065] Before explaining the embodiments of the present invention in detail, the application scenarios involved in the embodiments of the present invention are explained first.

[0066] With the development of autonomous robots, more and more attention has been paid to the technology of autonomous positioning and map construction of robots. At present, autonomous positioning and map building of robots are usually performed through SLAM algorithms. Among them, when the robot autonomously locates and constructs the map through the SLAM algorithm, the laser data and visual data can be obtained through the laser sensor and the vision sensor carried on the robot respectively, and the closed-loop detection of the robot can be carried out through th...

Abstract

The invention discloses a method, a device and a storage medium for determining a laser data search range, belonging to the technical field of robotics. The method includes: acquiring the current visual image and current laser data collected at the current position; performing visual closed-loop detection based on the current visual image and the visual database to determine key closed-loop data, and the visual database is used to store the data collected by the robot. visual data, the closed-loop key data is the data describing the current position of the robot as the position it has been before the current time; when the closed-loop key data is determined, it is based on the data collected when the closed-loop key data is collected. The laser data and the current laser data are used to determine the laser data search range for laser closed-loop detection. The invention can determine the laser data search range for laser detection, reduces the calculation amount and time consuming of laser closed-loop detection, and improves the efficiency of laser closed-loop detection.

Description

technical field [0001] The invention relates to the technical field of robotics, in particular to a method, device and storage medium for determining a laser data search range. Background technique [0002] An autonomous robot refers to a robot that carries various necessary sensors and controllers, and can complete certain tasks independently without the input and control of external human information during operation. For example, common autonomous robots include sweeping robots. Among them, the autonomy of the robot is mainly reflected in the autonomous navigation of the robot. In an unknown environment, to realize the autonomous navigation of the robot, it is necessary to draw a map of the environment where the robot is located. [0003] Currently, maps can be drawn through the SLAM (Simultaneous Localization and Mapping) algorithm. Among them, when drawing a map through the SLAM algorithm, laser data and visual data are obtained through the laser sensor and visual sen...
