Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual cursor placement is used on two-dimensional images for measurement, then measurement capability is achieved, but measurement precision deteriorates due to difficulty in visualizing three-dimensional space
Solution Approach 1:
The patent creates a three-dimensional virtual copy or representation of the measured object based on the two-dimensional image data. This virtual model allows users to perform measurements in a three-dimensional space that accurately reflects the actual object geometry, eliminating the visualization difficulties of flat images while maintaining measurement capability.
2Productivity
If automated feature detection is implemented, then productivity improves through reduced manual effort, but device complexity increases due to additional processing requirements
Solution Approach 1:
The system performs automated detection of measurable features, automatic selection of appropriate measurement types, and autonomous positioning of measurement markers without requiring manual user input for each step. The computer vision algorithms independently analyze the image data, identify relevant features, and execute the measurement process, thereby significantly improving productivity while the complexity is managed through integrated software processing.

AI summary
A method and system for detecting a known measurable object feature using a video inspection system. The method and system displays an image of a viewed object and detects a known measurable object feature on the viewed object. The method and system then displays a set of available measurement types including a measurement type associated with the detected known measurable object feature and/or automatically positions a plurality of measurement markers on the displayed image based on the measurement type associated with the detected known measurable object feature.
