Contrast

Specify whether or not to use features of 2D image when judging the connection of the 3D points constituting the 3D blob. If the checkbox is checked, those image features whose contrast is higher than the threshold are used for judging the connection of the 3D points constituting the 3D blob. Set a value between 1 and 200.

In the case that same size workpieces are located densely as shown in the figure below, the connection judgment by using Z height of 3D data causes to be found one 3D blob including some workpieces.

But the connection judgment by using Z height of 3D data and features of 2D image causes to be found a 3D blob corresponding to each workpiece.
