Abstract Digital image processing is proposed to measure the size of aggregate.Illuminant source commonly has two installation methods,which are front illuminant installation and backlight installation. Aggregate has two motion states,which are lying on the conveyer and falling from conveyer,in production line. A proper illuminant installation is proposed by studying two motion states of aggregate. When shooting the falling aggregate,speed of conveyer,installation angle of conveyer,thickness of aggregate and camera installation height would effect shooting results.Getting optimized parameters by studying the effects of these factors on the aggregate dispersion using EDEM simulation software.By comparing image processing effects and size distribution statistical results of three shooting methods, a practical way to detect aggregate size distribution is proposed.
