Omron Healthcare ZFX-C Sensitive search, HueNEW, Position, Width, Bright Count, Defect Region

A further improvement is the balance achieved in revolving searches that occur in pattern matching for a revolving work. The most time-consuming360-degree revolving search can be performed with an excellent accuracy.

NEW

Tailored Measurement item

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.

Shape measurement item

Pattern search Fastest in the industry

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

Bright and Hue measurement item

HueNEW

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).

Normal time When lowering illumination

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.

Edge measurement item

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.

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.

Based on the change in brightness, the presense of a screw (OK or NG) is determined.

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.

Screen registration function

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.

Gray filtering setup using double screen

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.

Calculations 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.
