                                                                                                                                                                照明系統為圖像采集提供了合適的照明,便于后續圖像的處理和分析。

                                                                                                                                                                圖像數字化模塊、數字圖像處理模塊、智能判斷決策模塊是機器視覺系統的核心,使計算機進行特定的處理。 經過處理的數字信號被轉換為視頻信號顯示在顯示器上,從圖像采集板的輸出端子輸出,需要控制適當的致動器。

                                                                                                                                                                機械控制執行模塊按照計算機指令工作,最終完成系統所需的任務。
