Multiple Positional Measurement

The IV-S30 can detect up to 128 workpieces whose images exceed the specified matching

level (gray search) or threshold value (edge detection) from the reference image.

- The positional deviation measurement needs to have a number of positions registered for

measurement. However, this measurement only requires you to register one position and

reduces the set up time.

Purpose

Example

Measure the position of workpieces with a complicated light level that cannot be converted

into binary images.

[Measurement results]

- Number of images detected

- Coordinates detected

[Measurement results]

- Number of images detected

- Coordinates and degree of match detected for each image

● Gray search

● Edge detection

This is useful for obtaining the distance between the coordinates of a position.

- L1 to L3 can be calculated by measuring distances and angles.
