After you create a binary image and improve it, you can make particle
measurements. NI Vision can return the measurements in uncalibrated pixels or calibrated
real-world units. With these measurements you can determine the location of particles and
their shape features. Use the following VIs to perform particle measurements:
-
IMAQ Particle Analysis
Report—This VI returns the number of particles in an image and an array of
reports containing 11 of the most commonly used measurements, including the particle area,
bounding rectangle, and center of mass.
-
IMAQ Particle Analysis—This VI returns
an array containing your choice of up to 80 particle measurements.
Refer to
the Particle Measurements section of the NI Vision Concepts
Help for a list of all the measurements that the IMAQ Particle Analysis VI can
return.
