3D Data Position Conversion for Accurate Size Relationships
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for converting three-dimensional data into a formed object do not allow for suitable reduction or enlargement, leading to output objects that may not meet user needs, as they fail to accurately reproduce the size relationships between physical objects in three-dimensional space.
Innovation Solution
An image processing apparatus and method that obtain three-dimensional data, convert positions in a predetermined direction based on the object's position, and output the converted data, allowing for deformation of three-dimensional shape data through reduction or enlargement suitable to the formed object, using a compression profile function to adjust the z-axis direction independently or in association with x and y axes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If three-dimensional data is converted into a formed object using existing methods, then the formed object can be output, but the size relationships between physical objects in three-dimensional space are not accurately reproduced
Solution Approach 1:
The patent implements dynamic scaling by allowing independent adjustment of reduction/enlargement ratios for different directional components (x, y, z axes) of three-dimensional data. This enables the system to adaptively transform the spatial relationships of physical objects according to user needs, resolving the contradiction between maintaining accurate size relationships and providing customization flexibility.
Solution Approach 2:
The patent changes the parameters of three-dimensional data by introducing separate scaling factors for different spatial directions. By modifying the reduction/enlargement parameters independently for each axis, the system can accurately control the size relationships of formed objects while providing versatile customization options for different application scenarios.
2Ease of manufacture
If uniform reduction or enlargement is applied to three-dimensional data, then the processing is simple, but the size relationships between different physical objects cannot be optimized
Solution Approach 1:
The patent segments the uniform scaling operation into directional components, allowing independent reduction or enlargement ratios for different axes (x, y, z). This segmentation enables precise control over the size relationships of different physical objects while maintaining relatively simple processing through component-wise transformation rather than complex global optimization.
