Map correction method, device and electronic equipment

Abstract

Disclosed are a map correction method, device and electronic equipment. Determine a first movement track and a preset visual scale of the movable device, and generate at least one second movement track with a visual scale according to the first movement track and the preset visual scale. For example, at least one second movement trajectory with a visual scale similar to the first movement trajectory is determined around the first movement trajectory, and then a preset road trajectory within the location area where the first movement trajectory is located is acquired. A third movement trajectory with a visual scale of the movable device is determined according to the preset road trajectory and at least one second movement trajectory. Since the movable device often moves on the preset road trajectory, the real moving trajectory of the movable device on the preset road trajectory can be obtained, that is, the third moving trajectory, and then corrected according to the visual scale of the third moving trajectory The map generated when the mobile device moves, so that the corrected map can be objectively standardized.

Description

technical field [0001] The present application relates to the field of computer technology, and more specifically, to a map correction method, device and electronic equipment. Background technique [0002] With the rapid development of technology, robots have been widely used in all walks of life. In the process of moving robots, it is often necessary to build maps by taking images of the surrounding environment. [0003] In the process of building a map, it is often necessary to locate the robot. If the positioning is accurate, the visual scale of the generated map will be the standard visual scale, thereby making the generated map objective and standard. If the positioning is inaccurate, the visual scale of the generated map will be The visual scale is not a standard visual scale, which makes the generated map not objectively standard. [0004] When the robot is moving, there will be friction between the wheels of the robot and the ground, resulting in a small error betwe...

Problems solved by technology

[0003] In the process of building a map, it is often necessary to locate the robot. If the positioning is accurate, the visual scale of the generated map will be the standard visual scale, thereby making the generated map objective and standard. If the positioning is inaccurate, the visual scale of the generated map will be The visual scale is not a standard visual scale, which makes the generated map not objectively standard

[0004] When the robot is moving, there will be friction between the wheels of the robot and the ground, resulting in a small error between the moving mileage of the robot determined by the odometer and the actual moving mileage of the robot. As the moving mileage increases, the cumulative error It will become bigger and bigger, and it will not be able to accurately locate the robot, which will lead to the generated map not being objectively standard
