PixelLength Result 
 
PixelLength Result 
 
Applies To 
Vision Objects: Line 
 
Description 
Returns the length in pixels of the distance between the starting and ending point of the line. 
 
Usage 
VGet  Sequence.Object.PixelLength, var 
Sequence  Name of a sequence or string variable containing a sequence name. 
Object 
Name of an object or string variable containing an object name.  The object must exist in the 
specified sequence. 
var 
Real variable that will contain the value of the result. 
 
Values 
Real number in pixels  
 
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.
