    摘要:

    基于現(xiàn)場可編程門陣列FPGA并行運算平臺,設(shè)計了一種采用線陣CCD芯片的西瓜子色選機(jī)系統(tǒng),。硬件平臺將CCD芯片驅(qū)動,、動態(tài)圖像的采集與處理、分類計算及氣閥控制信號輸出等集中在一個FPGA芯片上實現(xiàn),。色選機(jī)試制系統(tǒng)產(chǎn)量為1.2~1.8t/h,,色選精度97.7%,帶出比為6~8,。與傳統(tǒng)工控機(jī)平臺進(jìn)行對比試驗,,驗證了基于FPGA的西瓜子色選機(jī)系統(tǒng)具有良好的實時性和高效性。

    Abstract:

    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.
