Virtual Object Box Size Matching for AR Display Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual object generation methods in augmented reality often result in inefficient use of virtual object boxes, leading to suboptimal display effects due to mismatched material sizes and box dimensions.
Innovation Solution
A method that acquires position and pose information of a virtual object box, determines its size information, selects a target material matching the box's size, and renders the material into the box to generate a virtual object, thereby improving size matching and display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If materials are allocated to virtual object boxes according to a fixed order and scaled to fit, then the material is completely located in the virtual object box, but there is large space remaining in the virtual object box affecting the display effect
Solution Approach 1:
The patent changes the parameter selection criterion from fixed order to size matching. Specifically, it selects materials whose size parameters (particularly the longer edge length) closely match the virtual object box dimensions, transforming the allocation from a sequential process to a size-based matching process that eliminates wasted space while ensuring complete material location within the box.
2Illumination intensity
If a higher material is placed in a wider virtual object box, then the material can be completely displayed, but there is large space remaining in the virtual object box
Solution Approach 1:
The patent applies local quality by making the material selection adaptive to each specific virtual object box's size characteristics. Instead of using a uniform allocation strategy, it evaluates the size relationship between each material and its target box, selecting materials with locally optimized size matching that fills the specific spatial characteristics of each box without leaving excessive empty space.
3Ease of manufacture
If materials are selected without considering virtual object box size, then the allocation process is simple, but the size matching degree between scaled material and virtual object box is poor
Solution Approach 1:
The patent introduces size parameter matching as the selection criterion, changing from simple sequential allocation to size-based selection. The system compares the size parameters of materials with virtual object box dimensions and selects materials with optimal matching degrees, thereby improving precision while maintaining automated selection that does not significantly increase operational complexity.
