Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed television camera captures a three-dimensional space and a tracking laser distance measuring device measures positions, then position measurement capability is improved, but synchronization and matching accuracy between laser irradiation position and work position deteriorates
Solution Approach 1:
The patent introduces a monitor screen as an intermediary element that displays both the laser irradiation position (from the tracking laser distance measuring device) and the work position (from the three-dimensional space capture) in a common coordinate system. This visual intermediary enables precise matching and synchronization between the two positions by allowing operators to see their relative positions and make adjustments accordingly.
Solution Approach 2:
The monitor screen serves multiple functions: it displays the three-dimensional space capture from the fixed television camera, shows the laser irradiation position from the tracking laser distance measuring device, and provides a common reference frame for matching both positions. This multi-functional display system resolves the synchronization issue by making both position systems visible and comparable simultaneously.
2Measurement precision
If interpolation calculations are used to determine drive values for the tracking laser distance measuring machine, then drive value accuracy is improved, but computational complexity increases
Solution Approach 1:
The patent performs interpolation calculations in advance to create a pre-computed mapping relationship between monitor screen positions and three-dimensional space coordinates. By preparing this correspondence data beforehand, the system avoids performing complex real-time calculations during operation, thus reducing computational complexity while maintaining accuracy.
Solution Approach 2:
The system creates a copied or mapped representation of the three-dimensional space on the two-dimensional monitor screen through interpolation calculations. This virtual copy allows the system to work with simplified coordinates while maintaining accurate correspondence to the real three-dimensional positions, reducing computational complexity.

AI summary
The function of the three-dimensional television camera can be provided by attaching the distance to the two-dimensional position of the television camera by the distance meter side of the position of the image captured by the television camera. The high-speed tracking of the tracking mirror and the high image quality of the tracking television camera captured image enable a plurality of detailed image recognition and enable tracking image recognition of a three-dimensional space close to human status determination. The drive device for numerical control, which operates in the dimension space, is driven in that space by grasping and sharing the location of the working space. The position of the working space of the drive device for numerical control is measured.
