Example
The distance and angle of the centers of detected points can be measured by the
center detection function and the edge detection function in a gray scale search and
the center of grevity detection function, which is a part of the labeling process.
Measurement for mounting electronic components
[Measuring an IC package]
Reference images a and b are recorded when the crosshair cursor is placed on
the edge of the IC package.
· Measuring sequence
1 Obtain the center points of images a and b by running a 2 point gray scale
search.
2 Determine the distance between the two center points.
Applications
· For details about measuring the distance, X coordinate distance, and Y coordinate distance of
two manually designated points, see the MANL-MESR (manual measurement) section for the
crosshair cursor display (page 8·8).
