Vision Sensor Manual
- Colored object with certain size and variable position in the ROI
For newly generated detectors, all parameters are preset as standard values, suitable for many
applications.
4.6.3.14.2.1 Color histogram
Depending from selected color model there are displayed histograms for RGB, HSV or LAB. The
histogram shows the distribution of colors in region of interest. By the buttons there can be switched on
and off single channels. Limits for color detection can by set by moving small markings below the
histogram. The selected range of colors is shown by colored areas. Crossing the limits results in invertion
of the selection. If a color can be detected reliable by using only one channel, the other channels have to be
set to max./min. limits to avoid disturbing influence to detection.
