Vehicle Measurement Base Using Optical Reference Systems

The patent replaces complex mechanical connection systems with optical reference systems. Instead of using mechanical linkages and calibrated mechanics to establish spatial relationships between measurement stations, the invention uses optical fields and reference targets that can be detected by imaging systems. This substitution eliminates the need for physical mechanical connections while maintaining the ability to determine six degrees of freedom with high precision.

The patent uses optical copies and imaging of reference targets to establish spatial relationships. Rather than requiring direct mechanical connections between measurement stations, the system creates optical representations (images) of reference targets and uses these copies to calculate spatial positions and orientations. This allows cross-referencing to be performed through image processing and coordinate transformation rather than through complex mechanical linkages.

The patent replaces stability-dependent mechanical connections with optical reference systems that are inherently more stable. Optical reference targets and imaging systems are not affected by thermal expansion or mechanical settling in the same way mechanical linkages are. The optical field maintains its geometric relationships regardless of thermal or mechanical changes to the supporting structure, providing inherent stability without requiring complex compensation mechanisms.

The patent transitions from measuring stability in mechanical dimensions to using optical field dimensions. By establishing reference relationships through optical paths rather than mechanical connections, the system achieves stability in a different dimensional space where thermal and mechanical disturbances have less impact. The optical reference system maintains its integrity even when the physical support structure experiences thermal or mechanical changes.

The patent uses optical imaging to create copies of reference targets, allowing spatial relationships to be determined through image analysis rather than direct physical measurement. The imaging systems capture optical representations of reference targets and use coordinate transformation to calculate precise spatial positions. This approach enables high-precision measurement without requiring large physical distances or complex mechanical measurement apparatus.

The patent replaces mechanical measurement systems with optical imaging systems. Instead of using physical rulers, calipers, or mechanical gauges that require significant space and manual operation, the invention uses cameras and image processing to automatically determine spatial relationships. This substitution dramatically reduces the equipment footprint while maintaining or improving measurement precision through automated image analysis and coordinate transformation.
