Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional three-dimensional measurement device is used, then measurement capability is provided for specific applications, but versatility and ease of operation deteriorate due to specialized configuration and complex knowledge requirements
Solution Approach 1:
The system enables a single three-dimensional measurement device to be universally applied across different manufacturing applications by automatically converting slant images to front view images. The conversion means transforms images captured from arbitrary camera orientations into standardized front view representations, allowing the same device to measure diverse objects (printed circuit substrates, mechanical parts, products) without reconfiguration, thus achieving multi-functionality and broad adaptability
2Measurement precision
If a conventional three-dimensional measurement device is used, then measurement function is provided, but ease of operation deteriorates due to requirement of special knowledge for full utilization
Solution Approach 1:
The system implements self-service operation by automatically performing image conversion from slant view to front view without requiring user intervention or specialized knowledge. The conversion means autonomously processes the captured images, calculates appropriate conversion parameters, and generates standardized front view images for measurement, enabling operators with basic skills to fully utilize the three-dimensional measurement functionality
Solution Approach 2:
The system performs preliminary image conversion before the measurement process. By pre-converting slant images to front view images and pre-calculating conversion parameters, the system prepares standardized measurement data in advance, eliminating the need for users to perform complex operations during actual measurement and simplifying the user interface
3Adaptability or versatility
If camera is arranged in slant direction, then measurement flexibility is improved, but setting complexity increases because region setting cannot be performed on slant images
Solution Approach 1:
The conversion means acts as an intermediary between the slant image capture and the region setting process. It automatically transforms slant images into front view images, providing a standardized intermediate representation that enables simple region setting. This intermediary conversion eliminates the complexity of performing region setting directly on slant images while maintaining camera arrangement flexibility

AI summary
An image processing device for the user to easily perform the setting for specifying the location to be performed with three dimensional measurement on the image where the photographed is shown, the device including an imaging section (1) with a first camera (C0), arranged with the optical axis directed in the vertical direction, for generating a front image of a work W, and a second camera (C1), arranged with the optical axis directed in a slanted direction, for generating a slant image of the work W. In the setting prior to the measurement, the setting object is photographed with each camera (C0, C1), and the setting is performed pm the specified region for specifying the position to be measured by the user using the front image from the first camera C0. In time of the measurement, the specified region is defined in the front image from the first camera (C0) based on the setting, and the process of specifying the position to be measured is performed in the relevant region. Furthermore, the position corresponding to the position specified in the front image is specified, and the process of calculating the three dimensional coordinate is performed with respect to the slant image from the second camera (C1).
