Innovation Solution
An image processing apparatus and method that acquires three-dimensional coordinates and two-dimensional coordinates, generates unit length information based on the distance between imaging positions, and outputs a composite image showing the object and three-dimensional image in a comparable manner, enabling users to visualize the size of target objects in real space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If three-dimensional images are displayed without real-world measurement correlation, then the visualization is simple and quick, but users cannot accurately understand the size of target objects in real space
Solution Approach 1:
The patent introduces a virtual measurer as an intermediary element superimposed on the three-dimensional image. This measurer includes scale indicators and measurement markings that bridge the gap between the abstract three-dimensional coordinates and real-world dimensions, enabling users to interpret object sizes without complex measurement tools or procedures
Solution Approach 2:
The system creates a virtual copy of the measurer (with known real-world dimensions) and superimposes it onto the three-dimensional image at corresponding spatial positions. By comparing the virtual measurer's scale markings with the target object's appearance in the image, users can accurately determine real-world sizes without requiring direct physical measurement
2Measurement precision
If unit length information is generated based on distance between imaging positions, then real-world size correlation is achieved, but the processing time and computational load increase
Solution Approach 1:
The system pre-calculates and stores unit length information that correlates three-dimensional coordinate distances with real-world distances before the actual measurement process. This pre-computed mapping relationship allows for rapid size determination during image analysis without performing complex real-time calculations
Solution Approach 2:
The patent transforms the measurement problem by changing the parameter representation - instead of calculating real-world distances directly from complex geometric relationships, the system uses pre-established parameter mappings between three-dimensional coordinate systems and real-world measurement scales, significantly simplifying the computation
3Loss of information
If three-dimensional coordinates and two-dimensional coordinates are correlated to generate measurable objects, then size understanding is improved, but the device complexity and processing requirements increase
Solution Approach 1:
The patent segments the coordinate processing into distinct functional components: (1) acquisition of three-dimensional coordinates from depth information, (2) acquisition of two-dimensional coordinates from image positions, (3) generation of unit length information from spatial relationships, and (4) synthesis of measurable objects with scale indicators. This segmentation allows each component to be optimized independently and simplifies the overall system architecture
