基于成熟西红柿与青西红柿、土块及石块等的颜色和形状差异,针对西红柿色选机的加工西红柿分选检测系统进行了设计研究,利用线阵CCD识别技术检测它们之间的差异,利用大规模可编程逻辑器件(FPGA/CPLD)技术对其信号进行采集和处理,完成对于分选检测系统的搭建。 Based on the differences in color and shape between ripe tomatoes and green tomatoes, clods and stones, the processing tomato sorting and testing system for tomato color sorter was designed and studied. The differences between them were detected by using linear CCD identification technique. Large-scale programmable logic device (FPGA / CPLD) technology for its signal acquisition and processing, to complete the construction of sorting and testing system.
