Make Particle Measurements

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 Chapter 10, Particle Measurements, of the NI Vision Concepts Manual for a list of all the measurements that the IMAQ Particle Analysis VI can return.
