Chapter 18: Distance and Angle Measurement

18-1 Outline

You can specify the settings for distance and angle measurement on the "COND" menu in the
positional deviation measurement, degree of match inspection, object identification by binary
conversion (select "YES" for center of gravity measurement), multiple position measurement, and
multiple degree of match inspection.
See page 4-4, 5-4, 10-5, 15-4, and 16-4
The distance and angle of the centers of the detected points can be measured using
the center detection function and the edge detection function in a gray scale search
and the center of gravity detection function, which is a part of the labeling process.
- This function can measure the following distances and angles: distance between two
Purpose
points, X coordinate distance, Y coordinate distance, the angle between three points,
the horizontal angle of two points, and the vertical angle of two points.
- The following points and lines can be set: center point, circle center point, gravity
center, point where two straight lines cross, line passing through two points.
Applications
Measurement for installed electronic components
[Measuring an IC package]
Examples
- Measuring sequence
1 Obtain the center points of images a and b by running a 2 point gray scale
2 Determine the distance between the two center points.
- For details about measuring the distance between two points, X coordinate distance, and Y
coordinate distance manually, see the MANL-MEAS (manual measurement) section (page 2-13) for
the crosshair cursor display.
