Halcon & C# 機器視覺學習日記二

導出Halcon算法

先安利一個虛擬攝像頭軟件 VCam，VCam軟件可以讓攝像直接採集一個視頻，爲以後的圖像處理學習提供很好的幫助。

VCam軟件界面

算法功能 ：打開攝像頭，實時採集並顯示

1. 使用Halcon軟件
   a. 使用助手新建一個Image Acquisition
   
   b. 檢測當前的設備
   
   c. 連接設備
   
   
   d. 實時採集圖像
   
   e. 播放視頻查看是否成功
   
   f. 插入代碼
   

g. 導出代碼，注意選擇你需要的版本`

導出的文件

//

// Non-ASCII strings in this file are encoded in local-8-bit encoding (cp936).
// 
// Please note that non-ASCII characters in string constants are exported
// as octal codes in order to guarantee that the strings are correctly

// 
// Source files with different encoding should not be mixed in one project.

using HalconDotNet;

public partial class HDevelopExport
{
#if !(NO_EXPORT_MAIN || NO_EXPORT_APP_MAIN)
  public HDevelopExport()
  {
    // Default settings used in HDevelop
    HOperatorSet.SetSystem("width", 512);
    HOperatorSet.SetSystem("height", 512);
    if (HalconAPI.isWindows)
      HOperatorSet.SetSystem("use_window_thread","true");
    action();

    // Local iconic variables 

    HObject ho_Image=null;

    // Local control variables 

    HTuple hv_AcqHandle = new HTuple();
    // Initialize local and output iconic variables 
    HOperatorSet.GenEmptyObj(out ho_Image);
    //Image Acquisition 02: Code generated by Image Acquisition 02
    hv_AcqHandle.Dispose();
    HOperatorSet.OpenFramegrabber("DirectShow", 1, 1, 0, 0, 0, 0, "default", 8, "rgb", 
        -1, "false", "default", "[0] e2eSoft VCam", 0, -1, out hv_AcqHandle);
    HOperatorSet.GrabImageStart(hv_AcqHandle, -1);
    while ((int)(1) != 0)
    {
      ho_Image.Dispose();
      HOperatorSet.GrabImageAsync(out ho_Image, hv_AcqHandle, -1);
      //Image Acquisition 02: Do something
    }
    HOperatorSet.CloseFramegrabber(hv_AcqHandle);
    ho_Image.Dispose();

    hv_AcqHandle.Dispose();

  }

#endif


}
#if !(NO_EXPORT_MAIN || NO_EXPORT_APP_MAIN)
public class HDevelopExportApp
{
  static void Main(string[] args)
  {
    new HDevelopExport();
  }
}
#endif

這樣你剛剛用Halcon實現的功能就導出來，將這個文件添加到你的C#工程中就可以輕鬆實現打開攝像頭，並且實時採集了。
