Abstract In image detection method of aggregate size, aggregate size characterization parameters are important factors influencing the result of size distribution. The developed aggregate size detection system based on image method consists of LED light source, industrial CCD camera and LabVIEW software platform. Different equivalent diameters are used to grade aggregate particle size, and different equivalent volumes are used to calculate aggregate quality. The difference aggregate size distribution results calculated from different equivalent diameters and different equivalent volumes are compared. In order to make the image detection useful for actual production, and convenient for production line staff to observe, a set of image size parameters matching screening method are obtained.The result shows that Minor Axis (Feret) could be used as equivalent diameter, while equivalent volume obtained by projected area×Minor Axis (Feret) has max-relativity with actual volume.

Key words： metrology particle size measurement aggregate image processing equivalent diameter equivalent volume
