Problems solved by technology

The amount of target location information that needs to be set in the prior art is huge. When the user's current location changes, the two-dimensional code information of the target location needs to be completely reset. In the prior art, the way of positioning and navigation based on the two-dimensional code is still Efficiency needs to be improved

Embodiment Construction

[0049] 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, not all, embodiments of the present invention. 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.

[0050]In the indoor positioning and navigation technology in the prior art, when the user needs to navigate, first detect the current location, and need to be able to obtain the QR code information of all target locations at the current location, and pre-fabricate all target locations in the form of QR codes into a picture, and display the picture on the pre-made electronic map; then scan the QR code of the target location corresponding to the picture to obtain...

Abstract

The embodiment of the invention provides a positioning and navigation method based on a two-dimensional code, a positioning and navigation device and equipment. The method comprises steps: in a prebuilt indoor connected graph, the target position information and a two-dimensional code representing the target position are acquired, wherein the prebuilt indoor connected graph comprises all indoor preset positions, two-dimensional codes of all preset positions and the preset position information corresponding to the two-dimensional codes; the two-dimensional code at the current position is scanned; in the prebuilt indoor connected graph, the current position information corresponding to the two-dimensional code at the current position is recognized; and in the prebuilt indoor connected graph, the best navigation path between the target position and the current position is displayed to enable to perform navigation to the target position from the current position according to the best navigation path. Through the method provided by the embodiment of the invention, layout of the two-dimensional code information of the target position can be reduced, and the efficiency of positioning and navigation based on the two-dimensional code is improved.

Description

technical field [0001] The present invention relates to the technical field of navigation and positioning, in particular to a positioning and navigation method, device and equipment based on a two-dimensional code. Background technique [0002] In today's diversified industries, the indoor scenes of people's activities have become increasingly large and complex. With the development of Internet of Things technology, indoor positioning and navigation technology will also continue to develop. Indoor positioning technology uses wireless networks and specific algorithms to measure the geographic location of unknown nodes in order to provide users with relevant geographic location information services, thereby providing users with navigation services. [0003] Nowadays, the main common indoor positioning technologies mainly include: Wi-Fi positioning technology, Bluetooth positioning technology, electromagnetic positioning technology, computer vision positioning, etc. It is mai...
