设计了孵化早期无精蛋自动挑选系统,结合各执行机构,对系统的电路及软件作了详细的研究。选取种蛋立位透光图像中的各部分的面积值作为无精蛋的识别特征。系统以TMS320DM642型DSP与EPM7128AETC型CPLD为控制核心,蛋盘设计为可自动切换的两种状态（孵化状态与检测状态）。种蛋的图像由CCD采集,由DSP经图像处理,神经网络识别后并由喷墨装置标记出无精蛋。
設計瞭孵化早期無精蛋自動挑選繫統,結閤各執行機構,對繫統的電路及軟件作瞭詳細的研究。選取種蛋立位透光圖像中的各部分的麵積值作為無精蛋的識彆特徵。繫統以TMS320DM642型DSP與EPM7128AETC型CPLD為控製覈心,蛋盤設計為可自動切換的兩種狀態（孵化狀態與檢測狀態）。種蛋的圖像由CCD採集,由DSP經圖像處理,神經網絡識彆後併由噴墨裝置標記齣無精蛋。

System for recognizing unfertilized egg automatically in early incubation stage was designed.Based on the control objects,the circuit and software of the system were studied in detail.The area of egg＇s yolk and white in the egg＇s vertical image were selected as the feature to recognize unfertilized egg.Control-core of this system was based on TMS320DM642 DSP and EPM7128AETC CPLD.The egg dish can be automatically switched from two states（hatch state and detection state）.The egg＇s image was captured by CCD camera,processed by DSP,classified by BP neural network,and the unfertilized egg was marked by Inkjet device controlled by CPLD.
