CR Type Algorithm - Joint (2D Only)

2. Joint Interpolate

● Enable this to include decimal place in pixel calculation.

● Value display in integer with converted from pixel decimal

calculation.

3. Joint size

● To adjust the joint inspection area.

● Yellow boxes shown below.

4. Joint Offset

● To adjust the joint boxes away from the component body.

5. Joint Plane

● Select the one that having best contrast among the Joint Area

and background.

● Good Joint having Dark in colour.

2. Joint Grey Thres

● Default set to 160.

● Fail Criteria: Grey scale measured > Threshold set

5. Joint Coverage Threshold

● Using 2D only (Grayscale)

● Every single pixels in the joint box will go through inspection.

● The pixels highlighted in purple colour is the passed pixels that

(Grayscale on that pixel < Gray Thres set).

● The number in yellow beside the joint box is the percentage of

pass pixels. Refer to example below.
