8) Eccentricity inspection
- This inspection algorithm is to inspect position of pin located in the center on component
shaped like a BNC connector based on outer circle. calculate the distance after searching
center position of outer circle and inner circle.
① Teaching method
(a) Select preview in operation window, and select preview-outside among eccentricity
inspection parameter.
(b) Select light type and image type to detect outer circle.
(c) Manually select binarization method in outer circle, and set binarization value for good
separation of outer circle to be detected
(d) Adjust radius according to outer circle to be detected, and adjust search range.
(e) Select type of boundary line to be detected in each search range of outer circle.
(f) Select preview-inside, and light type and select image type to detect inner circle.
(g) Manually select binarization method in inner circle, and set binarization value for good
separation of inner circle to be detected
(h) Adjust radius according to inner circle to be detected, and adjust search range.
(i) Select type of boundary line to be detected in each search range of inner circle.
(j) Conduct trial inspection to display radius of detected outer circle and inner circle in
current. Set allowable range of radius of detected circle in the range.
(k) Enter normal criteria in pixel unit for distance between detected outer circle and outer
circle center.

② Parameter description
Outer circle
- Light type and image type
Select light type and image type to detect outer circle. use light type and image
type on the top of inspection type.
Basically, select horizontal + vertical light and R or L type. In case of white light,
select vertical light and L type.
- Binarization method and binarization value
Select auto or manual binarization method, and adjust binarization value for good
separation of outer circle during manual selection.
- Radius: adjust radius to be close to outer circle to be detected.
