What method verifies and validates virtual inspection models against physical reality?

• A. Checkpoint comparisons with ground truth
• B. Vetted opinions from experts
• C. Historical records only
• D. No verification

Answer: (A)

Comparing the model’s outputs to real-world measurements and observations is how you verify and validate virtual inspection models against physical reality. This checkpoint comparisons with ground truth provides objective evidence of accuracy by directly assessing how closely the model matches what you actually observe in the real system, such as measured dimensions, sensor readings, or high-quality survey data. It lets you quantify errors, identify biases, and determine whether the model faithfully represents physical phenomena or conditions.

Relying on expert opinions isn’t enough here because judgments are subjective and can overlook discrepancies that numbers reveal. Historical records alone may be outdated or not reflect current states, so they can’t reliably confirm present accuracy. No verification means you have no evidence that the model aligns with reality.
