Including two shape measurement items, the system contains 5 categories and 9 types of 
Shape, Size, Edge, Bright and Hue, Application measurement items. 
It responds to the variety of inspection requirements in the manufacturing sites.

The individual threshold for the hue, saturation and brightness value 
parameters can be set up so that even if one of them is different, it can be 
detected accurately and intensely. On the other hand, by expanding the range 
for the brightness value and saturation, and so on, it is possible to stabilize the 
color detection in the hue without any interference from illumination alterations.
Based on the change in brightness, the 
presense of a screw (OK or NG) is 
determined.
In one captured image, it is possible to 
measure a multiple up to 32 regions. 
When carrying out difficult inspection, it is 
possible to set-up a color filter and color 
extraction for each measurement item.

Functions to support optimal measurements
For each measurement item, it is possible to 
run 8 types of gray filtering such as 
expansion and contraction to enable stable 
measurements. Through the “setup while 
looking” option that makes it possible to 
check the preview, the optimal gray filtering 
can be selected.
Gray filtering setup 
using double screen
It is possible to register the image used in the setup. When you use the live 
image during setup sometimes the set up is not correct due to position 
differences in the work. However, with the registered image saved in the SD 
memory card as a“master image for setup”, it can be easily verified when 
abnormal measurements occur.
Screen registration function
It is possible to make arithmetical calculations for measurement values, and 
calculations involving general functions, trigonometry, geometrical functions and 
logical functions. It is possible to setup internal variables, and complex calculations 
can be carried out.

  Pattern search
The shape measurement is a fundamental algorithm for image processing. By adopting a new 
image processor, the pattern search achieves a balance in the three factors of speed, 
precision and stabilization, something that 
was an arduous task until now. It now 
supports a 360-degree revolving search and 
a sub-pixel processing of 1000 to 1 pixel 
units as well as a multi area searcher. The 
robust pattern search can respond to the 
multitude of inspects and measurements of 
any application.
  Sensitive search
When it comes to the difficult processing of detecting small differences, the Omron's 
unique sensitive search matches 
work at a smallest detail and in doing 
so makes such detection all the more 
possible.It resists variations in 
position and density to capture even 
the smallest detail in the complex 
patterns.
  Hue
The three factors in color, i.e. hue, saturation and brightness 
value, are measured and digitalized. And whilst an accurate 
differentiation of the color is performed, it is also possible to 
measure the color variety with the deviation measurement 
function (with color camera connected).
  Bright
Measures the brightness 
within a region. It can be 
used for checking the 
presense of a component, 
etc., by generating 
average density and 
density deviation values.
  Position
The existence or not and the position 
of the edge is measured. Oblique 
edges can now be measured even in 
complex conditions and even more 
accurate position measurements can be taken. The peak 
bottom measurement function that can accurately capture 
the edges is now supported.
  Width
The width of the edge is measured. 
By using the edge partitioning 
method, it is possible to measure the 
maximum and minimum width.
  Count
The number of edges inside the area 
is counted. Based on the number of 
edges on the pre-registered good 
model, it counts the edges in the 
area and determines the correctness.
  Region
Detects the existence of work within a 
region and measures its size based on 
the area to perform various 
classification.
  Defect
It is used to detect smears, scratches, 
chipping and burrs on the work. Defects 
are displayed on the screen, which makes 
it ideal tool for visual inspection.
