Remarks

Unlike the Length result, the PixelLength result returns a value even if calibration has not yet been
performed. This is because the units are in pixels and no calibration is needed for pixel unit based
calculations. If the user needs a length in millimeters then a standalone or robot based camera calibration is
required.

Statistics

For the PixelLength result, the following statistics are available. PixelLengthMax, PixelLengthMean,
PixelLengthMin, PixelLengthStdDev. Please see Statistics in the Vision Guide manual for details about
using statistics.
