Design principles of the RVP system

The RVP system uses an industry standard CMOS image sensor to capture and then detect the position of features using the contrast between light and dark areas of the image. Data points are projected on to the location where the image contrast changes from light to dark. A detailed calibration model of the lens system transforms the co-ordinates of the projected point on the image to real-world, three dimensional co-ordinates on the part.
