Indoor navigation method and system based on video live-action navigation technology

Abstract

The invention provides an indoor navigation method based on a video live-action navigation technology. The method comprises the steps of: obtaining a path dividing node through modeling, and obtainingan on-site path node matched with the path dividing node through first visual angle video shooting, on the basis of processing and compressing path node videos, combining all path nodes in pairs to form a video node combination pair, calculating the shortest path corresponding to the path node combination pair, and forming the shortest path video data represented by the path node, namely the indoor navigation video data. And the user acquires the position information as starting point information according to the path node label or the path node picture, selects a destination as terminal point information through the user interaction terminal, and requests the shortest path video data matched with the starting point information and the terminal point information. The invention also provides an indoor navigation system. The conflict problem of navigation precision and cost in the prior art is overcome, and indoor navigation with no signal source, high precision and low cost is realized.

Description

technical field [0001] The present invention relates to the technical field of indoor navigation, in particular to an indoor navigation method and system based on video real-scene navigation technology. Background technique [0002] Indoor navigation has important practical value in real life. At present, the main indoor navigation technologies can be divided into the following three categories: indoor navigation technology based on location awareness, indoor navigation technology based on signal measurement, and indoor navigation technology based on sensors. Most of the indoor navigation technologies that can be put into commercial use use sensor-based indoor navigation Technology, commercial companies customize a set of base station construction plans for specific buildings, install base stations, and use navigation systems to complete accurate positioning and navigation inside buildings. Although this method is mature, due to its high cost, huge engineering volume, and h...
