Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in generating accurate virtual indoor space content due to difficulties in determining image capturing locations and movement paths within indoor environments.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS-based location tracking is used for outdoor environments, then location information can be easily acquired, but this method is not applicable for indoor environments where GPS signals are unavailable
Solution Approach 1:
The patent introduces relative location information as an intermediary solution to bridge the gap between outdoor GPS-based positioning and indoor positioning requirements. Instead of directly using GPS coordinates, the system captures images at multiple indoor points and stores relative location relationships between these points, enabling indoor navigation without GPS signals
Solution Approach 2:
The system creates a virtual copy of the indoor space by capturing omnidirectional images at multiple points and reconstructing the physical environment in virtual space. This virtual model serves as a substitute for direct GPS positioning, allowing users to navigate and locate themselves within indoor environments through the reconstructed virtual representation
2Reliability
If omnidirectional images are captured at multiple indoor points, then virtual indoor space content can be generated, but the complexity of capturing and processing images increases
Solution Approach 1:
The mobile terminal automatically performs image capture, processing, and virtual space generation without requiring external specialized equipment or complex manual operations. The terminal's existing cameras and processors are utilized to self-generate the virtual indoor space content, reducing the need for additional complex devices
Solution Approach 2:
The indoor space is divided into multiple discrete capture points, with omnidirectional images taken at each point. This segmentation approach allows the complex task of indoor mapping to be broken down into manageable discrete image captures, which are then systematically processed and assembled into the complete virtual representation
3Loss of information
If relative location information is stored for each indoor point, then movement paths can be tracked indoors, but the data storage and processing requirements increase
Solution Approach 1:
Instead of storing extensive raw sensor data or video footage to track movement paths, the system creates a simplified virtual copy of the indoor space with marked capture points. Relative location information is stored as compact coordinate relationships between these points, significantly reducing data storage requirements while preserving essential movement path information

AI summary
A server is provided. The server provides virtual indoor space content corresponding to a real indoor space. The server includes a memory; a communication module; and at least one processor operatively connected to the memory and the communication module. The at least one processor may receive image data to generate the virtual indoor space content from a mobile terminal through the communication module, the image data including, for each of a plurality of indoor points, an omnidirectional image acquired from each indoor point and relative location information on the indoor point, and generate the virtual indoor space content by mapping a plurality of virtual points corresponding to the plurality of indoor points in a virtual indoor space based on the relative location information.
