這幾天一直在折騰dalsa線陣相機，借鑑它的幫助文件和demo程式，終於實現了影象採集。記錄一下。
安裝dalsa相機驅動和它自帶的採集軟體後，在安裝目錄下Component資料夾內有一個dll檔案，這就是c#需要用到的，help資料夾內有開發文件，demo資料夾內是winform程式，examples資料夾內是控制檯程式。先用自帶的採集軟體，設定好引數，儲存為配置檔案，然後就可以用c#來讀取該配置檔案了，直接貼程式碼：

 //初始化相機類
        SapLocation m_ServerLocation;
        SapAcqDevice m_AcqDevice;
        SapBuffer m_Buffers;
        SapAcqDeviceToBuf m_Xfer;

            }

                    hWindowControl1.HalconWindow.SetPart(0, 0, 2000, 8192);
                    HOperatorSet.DispObj(ImageTemp,hWindowControl1.HalconWindow);
                   // HOperatorSet.WriteImage(ImageTemp, "bmp", 0, "C:\\Users\\dell\\Desktop\\3");

        private void button2_Click(object sender, EventArgs e)

            if (m_Xfer.Grab())
            {
                MessageBox.Show("開始採集");
            }
        }

以上是網口相機的採集程式，主要參照了demo程式，影象採集到記憶體後，使用halcon中的genimage函式從記憶體中直接讀取並生成影象，後續可以對影象進行相應的操作了。如果是camlink介面相機，主要要修改GetCameraInfo方法和其他地方，具體參照demo。
