基于FPGA和线阵CCD的色选实验平台研究

Study on color sorting experimental platform based on FPGA and linear CCD

提出了一种基于FPGA和线阵CCD的色选实验平台,利用线阵CCD对下落的大米进行在线动态扫描,通过FPGA对采集到的大米图像信息进行分析和处理,识别出异色米粒,并通过分离装置剔除不合格大米。详细介绍了硬件平台的设计以及采用的色选算法,该研究对高性能大米色选机的研制具有重要的参考价值。

A color sorting experiment platform based on FPGA and linear CCD is presented in this paper. Under Ihe platform, the dropping grains of rice is dynamically scanned by the linear CCD to acquire rice images, which are analyzed and processed by FPGA to identify heterochromatic grains of rice, then the unqualified grains of rice are picked out through the separating equipment. The design of the hardware platform and the color sorting algorithm are described in detail. This study provides important reference for the development of high-performance ric, e color sorter.
