Problems solved by technology

[0014] a) Although the accuracy is high, it depends on the ground markers and is easy to wear
[0015] b) Entering the scene requires a lot of manpower for measurement and laying
[0016] c) Once the equipment deviates greatly from the normal line, it cannot be corrected by markers

Embodiment Construction

[0062]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0063] The present invention provides a multi-device video navigation method and system in variable scenarios, which are mainly applied in variable and complex scenarios such as warehouse automation. The warehouse automation environment mainly includes mobile shelves and automatic navigation robots. The bottom of the mobile shelf has a space for the automatic navigation robot to enter. The automatic navigation robot can enter the bottom of the mobi...

Abstract

The invention discloses a multi-device visual navigation method and system under a variable scene. On one hand, data feature information of images is obtained by continuous shooting of scene images with multiple devices, and the data feature information of key frames is extracted and sent to a server end (or a cloud). On the other hand, the server end (or the cloud) fills a blank space of the scene by the latest obtained key frame data feature information to complete expansion of the navigation data of the scene; or the latest obtained key frame data feature information is added to replace most dissimilar data feature information in existing data in a region, to complete updating of the navigation data of the scene; and finally, the server hands out the calibrated and updated data featureinformation to each terminal device, real-time updating of the navigation data is ensured, and clustering autonomous navigation is realized.

Description

technical field [0001] The invention relates to the technical field of robot navigation, in particular to a multi-device visual navigation method and system in a variable scene. Background technique [0002] At present, automatic navigation robots have been widely used in warehouse automation, especially the goods-to-person system based on automatic navigation robots. At present, the positioning methods of more advanced automatic navigation robots in warehouses mainly include the following: [0003] 1. Laser positioning system based on excitation reflection [0004] a) Expensive [0005] b) The place where the reflector is installed cannot be blocked. When using it, it is necessary to reserve a large space on the walking path, which wastes a large space in the warehouse [0006] c) Affected by temperature [0007] d) For indoor use only. [0008] 2. Visual positioning based on indoor scene reconstruction [0009] a) The accuracy is low, and a large space needs to be re...
