Problems solved by technology

Due to the limited field of view angle of a single sensor device (such as a camera) used in the mapping, the map information obtained is limited, resulting in intelligent robots and other devices that can only be positioned from the perspective of the mapping
Once the intelligent robot and other equipment deviate from the original viewing angle or the original viewing angle is blocked, the positioning will fail, which will affect the positioning effect and user experience in the slightest, and endanger the lives of others in severe cases.

Embodiment Construction

[0028] In order to make the purpose, technical solution and advantages of the present application clearer, some embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0029] The first embodiment of the present application relates to a method for establishing a map, which is applied to a terminal or a cloud. Terminals can be intelligent robots, unmanned vehicles, navigation devices for the blind, etc. The cloud communicates with the terminal to provide the terminal with a map for positioning or directly provide the terminal with a positioning result. This embodiment uses a terminal as an example to illustrate the execution process of the method for creating a map, and the process of executing the method for creating ...

Abstract

Some embodiments of the present application provide a method for establishing a map, a positioning method, a device, a terminal, and a storage medium. The method for establishing a map is applied to a terminal or a cloud, and includes the following steps: acquiring image data of N different viewing angles; wherein, N is a positive integer; composing N image data of different viewing angles into full-view image data; data to create a full-view map.

Description

technical field [0001] The present application relates to the field of computer vision, in particular to a method for establishing a map, a positioning method, a device, a terminal and a storage medium. Background technique [0002] Devices such as intelligent robots or unmanned vehicles need real-time mapping and positioning to perceive the surrounding environment in an unknown environment. Only successful mapping and positioning can provide navigation and other functions for intelligent robots or unmanned vehicles. Assure. At present, mapping and positioning methods generally complete mapping and positioning based on map information collected from a single perspective. [0003] In the process of studying the prior art, the inventor found that the positioning in a single viewing angle has many limitations. Due to the limited field of view angle of a single sensor device (such as a camera) used in mapping, the map information obtained is limited, resulting in devices such ...
