• All pixels with grey value below the threshold value will be ignored. This filters out the
image background.
• The value 2*threshold is used in the calculation of the laser line width and height (see
below).
The output values are calculated column wise (see also Fig. 5.9):
Peak coordinate Vertical coordinate of the laser line peak
Laser line width The laser line width is the number of pixels that have a grey value above
2*threshold around the laser peak. If there are no pixels inside the laser line that have a
grey level above 2*threshold, then the laser line width is 0. In this case the threshold
value should be changed.
Laser line height The laser line height is the highest grey value of the detected laser line. If
there are no pixels inside the laser line that have a grey level above 2*threshold, then the
height is set to threshold. In this case the threshold value should be changed.
