1Measurement precision

If the visual sensor model position is manually adjusted by the operator while watching the imaged image, then the measurement object model can be accurately imaged, but time and labor are required for adjusting the position

Engineering Contradiction:

Improveimaging accuracyVSAvoidadjustment time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system performs self-adjustment by automatically calculating the visual sensor model position based on the measurement point position. The position determination unit computes the appropriate position without operator intervention, allowing the system to service itself rather than requiring manual adjustment while maintaining imaging accuracy.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical adjustment process is replaced with an automated computational system. The position determination unit uses coordinate transformation algorithms to calculate the visual sensor model position based on the measurement point, substituting the mechanical adjustment process with an automated information processing approach.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
