MVS-PM NSPECTION MODE

Inspection for Color, Flaw, Blob, Shape, etc.

6 inspection modes are available

Color Shape

Stain

The professional camera compares the differential ratio of the stored master image with the differential result of the target image to determine the Stain value.

When this value exceeds the upper limit or is less than the lower limit, It is defined as NG.

This is used to detect the presence of stain (flaws) on the surface of metal objects or defects In plastic materials.

The camera inspects the shape of the area that contains the selected color.

It counts the number of pixels that have a different color In this area to determine the Contour value (Lack of pixels). It counts the number of pixels outside of the area (background) which have the selected color to determine the Stain value. If either value exceeds the threshold, it is defined as NG. This is used when the target color is close to the background and is difficult to inspect by Its contour or differential Image. This is not good for checking black and white objects.

Contour

The camera compares the contour of the stored differential master image with the contour of the target object. It counts the number of pixels that do not match the Target contour to determine the Contour value (Lack of pixels). It counts the number of pixels outside of the Target contour area (background) which have the selected color to determine the Stain value.

If either value exceeds the threshold, It is defined as NG. This function is used when the contrast of the target object Is high and Inspecting the contour produces a more accurate result.

OK (correct direction) processed

NG (rotated) processed

The camera calculates the ratio of the number of pixels that have the selected color to all the pixels in the Inspection window. When it exceeds the upper limit or Is less than the lower limit, it is defined as NG.

This is used to detect color differences, especially when the color Is not stable and that there Is no need to detect object shape.

The camera compares the stored differential master Image with the target object. If the difference exceeds the threshold It is defined as NG.

This function is used to inspect metal parts with uneven lighting. It is not good for detecting color or its depth.

The camera will compare the difference between the full color image of the target and the stored image. If the sum of the difference exceeds the threshold value it is defined as NG.

This Is used to inspect color and depth of pictures and prints under stable lighting.
