Embodiment 1

[0027] see figure 1 , is a flowchart of the relocation method provided by the first embodiment of the present invention, including the following steps:

[0028] Step S10, acquiring the first attribute identifier of the area to be operated;

[0029] In the embodiment of the present invention, the first attribute identifier can be an image feature identifier, an air pressure value identifier, a magnetic field strength identifier or a wifi strength identifier or any combination thereof, and the first attribute identifier is used for characteristic identification of the area to be operated, so as to Prevent erroneous judgments caused by similar environments between different areas to be operated.

[0030] Among them, the combination of multiple identifications can avoid errors in similar environments. For example, there are multiple rooms with the same environment on the same floor. At this time, a combination of multiple attribute identifications can be used to mark the area to ...

Embodiment 2

[0050] see figure 2 , is a flow chart of the relocation method provided by the second embodiment of the present invention, including steps:

[0051] Step S11, obtaining the air pressure value of the area to be worked through a preset air pressure gauge, and determining the first attribute identifier according to the air pressure value;

[0052] Wherein, the step of determining the first attribute identifier according to the air pressure value may be:

[0053] setting the air pressure value obtained by the barometer as the second attribute identifier; or

[0054] matching the air pressure value obtained by the barometer with a preset barometer to obtain an air pressure level, and setting the air pressure level as the second attribute identifier; or

[0055] performing operations on the air pressure value obtained by the barometer based on a preset formula algorithm to obtain an operation value, and setting the operation value as the second attribute identifier;

Embodiment 3

[0090] see Figure 4 , is a schematic structural diagram of the relocation system 100 provided by the third embodiment of the present invention, including: a first attribute identifier acquisition unit 10, an environment map data acquisition unit 11, an environment map data determination unit 12, and a relocation unit 13, wherein:

[0091] A second attribute identifier acquiring unit 10, configured to acquire the first attribute identifier of the area to be operated;

[0092] An environmental map data acquisition unit 11, configured to acquire preset environmental map data, the environmental map data including a second attribute identifier;

[0093] The environmental map data determination unit 12 is configured to obtain environmental map data consistent with the attribute identification of the area to be operated when the first attribute identification is consistent with the second attribute identification.

[0094] The relocation unit 13 is configured to obtain local enviro...

Abstract

The invention is applicable to the technical field of mobile robots, and provides a repositioning method and system, a mobile robot and a storage medium. The method comprises: obtaining a first attribute identifier of to-be-operated area; obtaining preset environment map data, wherein the environment map data comprises a second attribute identifier; when the first attribute identifier is consistent with the second attribute identifier, acquiring environment map data consistent with the attribute identifier of the to-be-operated area; and acquiring local environment data of a to-be-worked area,comparing the local environment data with the environment map data with the attribute identifier of the to-be-worked area consistent, and acquiring map data corresponding to the environment data withthe matching rate greater than a preset threshold, thereby realizing repositioning. According to the invention, the first attribute identifier and the second attribute identifier are acquired, and the map data is identified in a dual-identifier manner, so that the accuracy of map repositioning is improved, and the phenomenon of repositioning misjudgment caused by similar environments is prevented.

Description

technical field [0001] The invention belongs to the technical field of mobile robots, and in particular relates to a relocation method, a system, a mobile robot and a storage medium. Background technique [0002] A mobile robot is a machine device that performs work automatically. It can accept human commands, run pre-programmed programs, and act according to principles formulated with artificial intelligence technology. Today's mobile robots are tasked with assisting or replacing humans in tasks such as manufacturing, construction, or hazardous work. The mobile robot can construct a map of the scene in accordance with the map construction algorithm, and then perform location-based work based on the constructed map. However, in some cases, there is a need for relocation of the mobile robot. The so-called relocation refers to randomly placing the mobile robot into a known map environment, and the mobile robot can find its own coordinates in the map. For example: when a mobi...
