【**Standard Value**】 Set the required distance value. If the detected distance is not within the standard value range, the run result will display distance judgment failure.

【**Compensation Value**】 The value to compensate on the detected distance result.

【**Upper/Lower Deviation**】 Set the allowable upper and lower range of the difference between the detected distance and the standard value.
    Formula: Measured Value + Compensation Value = [Standard Value + Lower Deviation, Standard Value + Upper Deviation]

【**Size Conversion**】
    Scale: Manually input a value to convert image coordinates to real-world coordinates.
    Calibration: Connect a calibration data source to convert image coordinates to real-world coordinates.
    
## Output Description
  Run Result: Outputs true if successful, false if failed.
  Distance Value: The distance from the input point to the input line.
  Deviation Value: The difference between the Distance Value and the Standard Value.
  Intersection Output: The intersection of the distance segment (from input point to input line) and the input line.
  Distance Segment: The distance segment from the input point to the input line.
  Segment Angle: The angle of the distance segment from the input point to the input line.
