Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If three-dimensional scan data is acquired using a three-dimensional scanner, then the shape data of the inspection target is obtained, but it is difficult for users to grasp whether necessary three-dimensional data has been acquired
Solution Approach 1:
The patent creates a visual copy of the three-dimensional scan data by generating a wireframe model that reproduces the acquired shape data. This wireframe representation serves as a visual replica that users can easily interpret to determine data completeness, transforming abstract numerical data into comprehensible visual information without requiring complex technical knowledge.
Solution Approach 2:
The patent employs color-coded indicators to represent different states of three-dimensional data acquisition. By assigning specific colors to indicate whether data has been successfully acquired or is missing, the system provides immediate visual feedback to users, making it effortless to assess data completeness at a glance without interpreting complex technical parameters.
2Reliability
If reference three-dimensional shape data is generated and displayed, then users can verify acquired data, but the system complexity increases
Solution Approach 1:
The patent generates reference three-dimensional shape data in advance by creating wireframe models from acquired scan data before the verification process begins. This preliminary preparation allows users to compare against a pre-established reference framework, simplifying the verification process and reducing the computational burden during actual inspection operations.
Solution Approach 2:
The patent transforms three-dimensional shape data into a wireframe representation that adds a visual dimension to the data. By converting solid model data into a skeletal wireframe structure, the system enables users to perceive data completeness and structural integrity through line patterns and geometric relationships, providing verification capability through dimensional transformation rather than complex analytical processing.

AI summary
It is easy for a user to grasp whether necessary three-dimensional data has been acquired when three-dimensional data is acquired by a three-dimensional scanner. A three-dimensional coordinate generation unit sequentially generates three-dimensional coordinates of a measurement workpiece based on an image including pattern light generated by a scanner imaging part. A display control part sequentially generates display data in which the three-dimensional coordinates of the measurement workpiece sequentially generated by the three-dimensional coordinate generation unit are superimposed on a three-dimensional shape based on referred three-dimensional shape data registered by a registration unit. A three-dimensional data generation unit generates three-dimensional shape data of the measurement workpiece based on the three-dimensional coordinates of the measurement workpiece. A measurement unit performs measurement based on a referred measurement element registered by the registration unit and the three-dimensional shape data of the measurement workpiece.
