Chapter 15: Multiple Positional Measurements

15-1 Outline

The IV-C35M can detect up to 128 workpieces whose images exceed the specified
matching level (gray search) or threshold value (edge detection) compared with the
reference image.
Purpose
- 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.
Position measurement of workpieces having complicated density conditions, that

could not be measured by conventional binary conversion and density processing.

- Number of images detected
- Coordinates and degree of match detected for each image
Edge detection
Example
This is useful for obtaining the distance between the coordinates of a position.
- L1 to L3 can be calculated by measuring distances and angles.
