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.
