Problems solved by technology

However, taking the sweeping robot as an example, the distance that the rollers can move on different materials of the ground is not the same, which makes the map constructed by SLAM technology in this field and the map of the actual physical space may be quite different.

Abstract

The invention discloses a map construction and positioning method, a client, a mobile robot and a storage medium. The method for annularly constructing the map comprises the following steps: selectinga first map segment and a second map segment which are constructed by utilizing a first map construction mode from a plurality of map segments; wherein the plurality of map segments are constructed by using at least one map construction mode, and the first map segment and the second map segment are separately constructed based on an interruption condition detected by the mobile robot; and fusingthe first map fragment and the second map fragment into one map fragment according to the pose deviation of the two map positions describing the same physical space in the first map fragment and the second map fragment. According to the method, the problem that the error of the map constructed by the mobile robot is relatively large due to the influence of the interruption condition is effectivelyreduced; and a plurality of independently constructed map segments are fused, so that the aim of integrating the plurality of map segments by the mobile robot is fulfilled.

Description

technical field [0001] The present application relates to the field of computer data processing, in particular to a method for constructing a map and positioning, a client, a mobile robot and a storage medium. Background technique [0002] A mobile robot is a machine device that performs work autonomously. It can accept human command, run pre-programmed programs, and act according to principles formulated with artificial intelligence technology. This type of mobile robot can be used indoors or outdoors, in industry or at home, can be used to replace security patrols, replace people to clean the ground, and can also be used for family companionship and office assistance. Due to the differences in the fields of application of different mobile robots, the moving methods of mobile robots used in various fields are different. For example, mobile robots can use wheeled movement, walking movement, chain movement, etc. With the update and iteration of the mobile technology of mobi...
