Camera(CL-5000): This 12 bit cooled line sensor camera captured slight contrast differences and output them as stable digital data.
|
|
|
MIL original technique detects defects, shallow line, and light unevenness, even in low brightness environment.
|
|
AYA-40VL real-time operation eliminates irregular illumination, shading, and emphasizes the defecive part of image automatically. |
|
|
|
Easy Data Management: The operator is able to easily save the defect image and the address information. For simpler system management, the AYA-40VLseries is equipped LAN connection.

AYA-40VL Ditection Examples |
|
Gel and foreign object on the glass
|
|
a. Input image |
 |
|
There are not enough brightness changes to have the threshold. |
|
|
b. Emphatic image |
 |
|
There are brightness differences with the glass surface, but still the lighting is uneven. |
|
|
c. Special filtered image |
 |
|
This algorithm only emphasizes the defecive part and eliminates ligting uneveness and noise, by surface uneveness, to have threshold. |
|
| |
|
Chipped edge of the glass
|
|
a. Emphatic image |
 |
|
Showing the chipped edge as the black dots. |
|
|
b. Special filtered image |
 |
|
This algorithm emphasizes the defecive part and eliminates ligting uneveness and noise, by surface uneveness, but still need to the inspection blind area on the edge. |
|
|
c. Edge erasing image |
 |
|
The edge is erased but not the defective part and the surface and noise were smoothen, SN ratio is increased. |
|
| |
|
Crosswise streak on the glass
|
|
a. Emphatic image |
|
|
There is the streak on perpendicular to the running direction. |
|
|
b. Edge enhancing image |
|
|
The streak is emphasized and the ligting uneveness and noise, by surface uneveness, are eliminated. Smoothing the depth to not to cause the detection accuracy variance even changing inspection objects. |
|
|
c. Labeling image |
|
|
The defect part are colored in red, which is filled with different colors by the size, the depth, and the numbers. |
|
|
|
|
|
Don't you have a hard time to inspect those objects? |
|
Application of Edge erasing 1: Missing edge of shaft or printed object |
|
a.Emphatic image |
|
|
The object have patterns on the surface |
|
|
b. Neighboring Pixel Summation image |
|
|
It might necessary to set the inspection blind spot or adding more camera because the edge is emphasized with defective part. |
|
|
c. Edge erasing image |
|
|
This function erases the edges of patterns to do real-time processing by one camera.
|
|
|
|
|
|
|
Application of Edge erasing2: 300 micron foreign object on convexo-concave surface plastic panel
|
|
a. Emphatic image |
|
|
There are the lept asperities are all over the panel, the defect is overlapped with those. |
|
|
b. Edge erasing image |
|
|
Smoothen the surface in real-time and the brigtness waveform shows the defect. |
|
|
c. Labeling image |
|
|
The defective part is colored in red.
