1. Joint Size & Joint Offset
● To adjust the sizes and the offset for joint inspection boxes
2. Joint Image Plane
● These are the types of 2D Lighting. Select the one with having highest
contrast among interested inspection region and the background.
● Usually choose angle 2+3
3. Joint Follow Locator
● Tick this to enable the joint inspection ROI follow the locator.
4. Joint Grey Thres
● Usually set to 160
4. Joint Height Thres
5. Joint Coverage Thres(%)
● To set the percentage to pass the joint inspection.
