Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional augmented reality technologies face challenges in efficiently storing and parsing three-dimensional picture information during remote interactions, leading to chaotic and inconvenient data management.
Innovation Solution
An image data encoding method that obtains three-dimensional picture information, encodes it according to a preset file format including file header, index, and data information, and a display method that parses and displays the encoded information to reconstruct the three-dimensional picture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If three-dimensional picture information is stored without a unified format, then storage flexibility is maintained, but data management becomes chaotic and parsing efficiency deteriorates
Solution Approach 1:
The patent transforms the storage format from unstructured/chaotic to structured by defining specific parameters and organization rules for three-dimensional picture information. The encoding standard establishes parameter definitions, data organization structures, and storage rules that convert flexible but chaotic storage into structured storage with improved parsing efficiency.
2Ease of operation
If three-dimensional picture information is encoded with detailed structure including file header, index, and data information, then parsing convenience is improved, but encoding complexity increases
Solution Approach 1:
The patent divides three-dimensional picture information into distinct segments: file header information, index information, and data information. Each segment serves a specific function and can be processed independently, which simplifies the encoding process by breaking down a complex task into manageable parts while simultaneously improving parsing convenience through structured organization.
Solution Approach 2:
The patent performs preliminary organization of three-dimensional picture information by creating a standardized encoding structure before actual storage. The file header, index, and data sections are prepared in advance with defined formats and rules, which reduces encoding complexity during actual operation while ensuring parsing convenience is already built into the structure.
3Speed
If a preset file format with index information recording reference point data is used, then data retrieval speed is improved, but file structure complexity increases
Solution Approach 1:
The patent introduces an index information structure as an intermediary between the file header and the actual data information. This index records reference point data that acts as a mediator to quickly locate and retrieve specific three-dimensional picture information without requiring complex file structure navigation, thereby improving data retrieval speed while maintaining manageable file structure complexity.
