Description
Return scaled image distance and physical-reference residual.
Conservation measurements separate nominal material composition, contact geometry, expansion and mechanical response. A volume fraction or clearance term evaluates supplied properties under a limited model; actual material compatibility, treatment effects and object stability require examination and specialist judgment.
Return scaled image distance and physical-reference residual.
When to use this tool
Use Condition Image Scale Residual when checking the stated conservation material, dimensional or mechanical term.
How to use the tool and how it works
- Enter imageDistance, referencePixels, referenceLength, suppliedPhysicalDistance. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read scaledDistance, residual. Use the output convention below.
Return scaled image distance and physical-reference residual. Require referencePixels > 0 and other distances >= 0; scaledDistance = imageDistance*referenceLength/referencePixels, residual = scaled-suppliedPhysicalDistance.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| imageDistance | Image Distance | Required. Finite number; minimum 0. |
| referencePixels | Reference Pixels | Required. Finite number; strictly above 0. |
| referenceLength | Reference Length | Required. Finite number; minimum 0. |
| suppliedPhysicalDistance | Supplied Physical Distance | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| scaledDistance | Scaled Distance | Required. Finite number. |
| residual | Signed observed/calculated-minus-reference difference under the operation specified above. | Required. Finite number. |

}Limitations and assumptions
- This assumes the same image scale and compatible units; no camera distortion, object identity or actual condition is verified.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use calibrated measurements, representative material tests and qualified conservation/engineering assessment before actual treatment, mounting or handling.
