Indoor Navigation Video Preview Using Pre-Acquired POI Routes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality (AR) navigation technologies require users to be present in an indoor scene to acquire real-time navigation pictures, limiting the ability to preview navigation routes and increasing power consumption.
Innovation Solution
A method for generating and acquiring navigation videos by pre-acquiring panoramic videos between points of interest (POIs) in indoor scenes, using a POI route relationship graph to determine and generate navigation videos based on user-defined origins and destinations, reducing the need for real-time acquisition and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If real-time acquisition of navigation pictures is performed, then navigation guidance is provided, but power consumption increases and preview capability is lost
Solution Approach 1:
The patent pre-acquires panoramic pictures and navigation routes between POIs and stores them in advance. When a user requests navigation, the system retrieves pre-acquired data rather than acquiring it in real-time, thereby reducing power consumption while enabling preview capability before the user arrives at the location.
Solution Approach 2:
The patent creates a virtual copy of the real-world navigation environment by acquiring panoramic pictures and route information, then stores this digital replica. Users can interact with this copy to preview navigation routes without needing to be physically present at the location, thus reducing power consumption while maintaining navigation functionality.
2Adaptability or versatility
If real-time acquisition of navigation pictures is performed, then current position navigation is enabled, but the user must be physically present in the indoor scene
Solution Approach 1:
The system pre-acquires and stores navigation data including panoramic pictures and routes between POIs. Users can then access and preview this pre-acquired navigation information from any location, not just when physically present in the indoor scene, thereby enhancing accessibility while enabling preview capability.
Solution Approach 2:
The patent introduces a server as an intermediary that stores and provides navigation data. This intermediary allows users to access pre-acquired navigation information remotely without needing to be physically present in the indoor scene, thus improving accessibility while enabling preview before arrival.
3Use of energy by moving object
If pre-acquisition of panoramic videos is performed, then power consumption is reduced, but data storage requirements increase
Solution Approach 1:
The patent segments the indoor navigation environment into discrete POI nodes and pre-acquires panoramic pictures and routes between these specific points rather than capturing the entire indoor space continuously. This segmentation approach reduces the total data volume required for storage while still enabling comprehensive navigation coverage and reducing power consumption during actual use.

AI summary
Navigation video generation and acquisition methods and apparatuses, a server, a device, and a medium are provided, which relate to the field of navigation technologies. The method includes: receiving, from a terminal, a navigation video obtaining request, the navigation video obtaining request including a route origin and a route destination within an indoor scene; determining, based on the route origin and the route destination, one or more second sub-videos from one or more first sub-videos corresponding to a point of interest (POI) route relationship graph, the POI route relationship graph including a navigation route between at least two POIs in the indoor scene; determining an identifier to a navigation video from the route origin to the route destination based on the one or more second sub-videos; and returning the identifier to the navigation video to the requesting terminal for displaying the navigation video at the terminal.
