1. Share Param

● To share the same setting for both gap detector boxes.

2. 3D Mode

● Can choose either 2D (greyscale) or 3D (Height) to detect the

edges.

For 2D Mode:

a. Image Plane

● These are the types of 2D Lighting. Select the one with

having highest contrast among interested inspection region

and the background.

b. Inner Bright, Outer Dark

● Tick this if the inner part is brighter than outer part.

● Untick this if the outer part is brighter than inner part.

● Refer the pictures beside for the definition of inner and outer.

c. Adjust Contrast

● Tick this to enable adjust contrast.

● If contrast set to 50 to 100:

For 3D Mode:

a. Inner Bright, Outer Dark

● Pixels that having height value will be in bright grayscale.

● Tick this if the inner part is brighter than outer part.

● Untick this if the outer part is brighter than inner part.

● Refer the pictures beside for the definition of inner and outer.

b. Adjust Height Contrast

● Tick this to enable adjust height contrast.

● If contrast set to 50 to 100:

Note that:

3D Mode will convert height vale to grayscale. Pixels that

having higher height value will having brighter greyscale.
