Solution Overview
Problem
Existing systems for virtual representations of spaces face challenges in efficiently identifying and comparing changes between updated representations, making it difficult and time-consuming for users to detect alterations in a space.
Innovation Solution
A method and system that retrieve a previous representation and a current representation of a target portion of a space, compare them to identify changes, map the changes within a three-dimensional (3D) representation, and store a change map defining the changes in context of the 3D representation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users manually compare two virtual representations of a space to identify changes, then they can detect alterations, but the process becomes time-consuming and difficult
Solution Approach 1:
The patent replaces manual visual comparison with automated computer-based image processing and comparison algorithms. The system automatically retrieves previous and current representations, compares them using digital image processing techniques, and generates change maps, eliminating the need for manual mechanical comparison while maintaining high detection accuracy
Solution Approach 2:
The patent creates virtual copies (digital representations) of the physical space that can be stored and compared without physically revisiting the location. These digital copies enable rapid automated comparison through computational algorithms, significantly reducing the time required to detect changes while maintaining precision
2Measurement precision
If detailed representations of the space are stored for comparison, then change detection accuracy improves, but system complexity and storage requirements increase
Solution Approach 1:
The patent extracts and stores only the essential visual information needed for change detection in digital representation format, rather than storing complete raw datasets. The system processes and stores key features that enable accurate comparison while minimizing storage requirements and system complexity
Solution Approach 2:
The patent introduces a server as an intermediary component that manages the storage, retrieval, and comparison of digital representations. This intermediary handles the complex processing tasks, separating the computational burden from the client devices and simplifying the overall system architecture while maintaining high comparison accuracy

AI summary
An example method includes: retrieving a previous representation representing a target portion of a space; obtaining a current representation representing the target portion of the space; comparing the previous representation to the current representation to identify a change in the target portion of the space; mapping the target portion of the space to a three-dimensional (3D) representation of the space to locate the change within the 3D representation; and storing a change map defining the change in context of the 3D representation.
