摘  要:
基于现场可编程门阵列FPGA并行运算平台,设计了一种采用线阵CCD芯片的西瓜子色选机系统。硬件平台将CCD芯片驱动、动态图像的采集与处理、分类计算及气阀控制信号输出等集中在一个FPGA芯片上实现。色选机试制系统产量为1.2~1.8 t/h,色选精度97.7%,带出比为6~8。与传统工控机平台进行对比试验,验证了基于FPGA的西瓜子色选机系统具有良好的实时性和高效性。

摘  要:
A kind of watermelon seeds sorter system with linear CCD chip was designed based on the FPGA parallel computing platform.Through integrating CCD driver,dynamic image acquisition and processing algorithms,classification algorithm and valve control signal output in one FPGA chip,the hardware platform were designed.The color sorter prototype system had an output of 1.2~1.8 t/h,color sorting accuracy was 97.7%,ratio of color separation mass was 6~8.The good real-time and efficiency of the watermelon seeds sorter system based on FPGA were verified by the experiments that compared with the traditional industrial computer platform.
