Abstract

The invention provides a method and a device for map construction. The method solves the problem that the prior art has a large data processing amount and low data processing efficiency. The method comprises 1, acquiring M depth information of M points of a first barrier and N depth information of N points of a second barrier, 2, based on the M depth information, determining if the first barrier satisfies a first preset rule, and based on the N depth information, determining if the second barrier satisfies the first preset rule, 3, when the first barrier satisfies the first preset rule, generating a first label for labeling the first barrier as a wall, 4, when the second barrier satisfies the first preset rule, generating a second label for labeling the second barrier as a wall, and 5, marking the first label and the second label on a first map to obtain a second map.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a method and device for constructing a map. Background technique [0002] With the continuous improvement and development of science and technology, there is a modern product - robot, which has the advantages of accurate calculation accuracy and saving manpower. More and more fields use robots to replace human work, especially some digital closed-loop control , Automated work in occasions that are harmful to people or in places with a large amount of calculation. [0003] During the walking process, the robot collects the distance information in the entire field of view, and judges the surrounding obstacles through the depth of the distance information. [0004] However, in the process of realizing the technical solution of the invention in the embodiment of the present application, the inventor of the present application found that the above-mentioned technology h...
