Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for correlating 3D data with images of measuring objects are challenging due to difficulties in aligning 3D data from position measurement apparatuses with site conditions and requiring stereoscopic viewing for stereo image measurements, which not everyone can easily achieve, and there is a demand for simpler stereoscopic display options, including with single photographic images.
Innovation Solution
A three-dimensional image display apparatus and method that integrates 3D measurement data with stereo images by determining relative orientation, forming models based on corresponding points, and applying stereoscopic texture to create a pseudo-stereoscopic representation, allowing for easier recognition and visualization without the need for stereoscopic systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If stereo image measurement approach is used to obtain 3D data, then a large number of three-dimensional coordinates can be obtained conveniently, but stereoscopic monitor or deflector glasses are required which not everyone can easily recognize
Solution Approach 1:
The patent creates a two-dimensional image that copies and represents the three-dimensional measurement data in a format visible to the naked eye. The 3D coordinates are transformed into a 2D visual representation that preserves spatial information without requiring stereoscopic viewing equipment.
Solution Approach 2:
The patent converts three-dimensional measurement data into a two-dimensional display format. By projecting 3D coordinates onto a 2D plane with appropriate visual encoding, the system maintains the productivity benefit of stereo measurement while eliminating the need for stereoscopic viewing equipment.
2Measurement precision
If three-dimensional position measurement apparatus is used, then accurate three-dimensional coordinate data is obtained, but it is difficult to correlate with site conditions and decide which part of measuring object is measured
Solution Approach 1:
The patent merges the 3D measurement data with the 2D image data by superimposing them in a coordinated display system. The 3D coordinates are visually correlated with their corresponding locations on the 2D image, making it easy to understand which parts of the measuring object were measured and their spatial relationships.
Solution Approach 2:
The patent introduces a 2D image as an intermediary between the 3D measurement data and the user. This intermediary visual representation makes the abstract 3D coordinate data tangible and easily correlatable with the actual measuring object and site conditions.
3Reliability
If orientation work is performed to tie 3D data with stereo image, then 3D data and stereo image can be correlated, but the work involves great differences among individuals and cannot be performed with ease and accuracy
Solution Approach 1:
The system performs automatic orientation by having the measuring object itself provide reference features that can be automatically detected and matched between the 2D image and 3D data. This self-service approach eliminates the need for manual orientation work that varies among individuals.
Solution Approach 2:
The patent replaces the manual mechanical orientation process with an automated computational system. Image processing algorithms automatically identify corresponding points and establish the transformation between 2D image coordinates and 3D measurement coordinates, eliminating human variability.
4Adaptability or versatility
If stereoscopic display is demanded for single photographic image, then customers want stereoscopic representation, but conventional methods require stereo images and stereoscopic equipment
Solution Approach 1:
The patent changes the display parameter from stereoscopic (3D) to two-dimensional, while maintaining the visual representation of three-dimensional measurement data. By using perspective projection and visual encoding techniques on a 2D plane, the system provides stereoscopic-like information without requiring stereoscopic display equipment.
