织梦网站建设过程/网络营销渠道有哪三类

映美精黑白相机，用wpf+halcon开发取图
1.到官网下载，开发包

1sdk 2c++开发例子 3c#开发例子

2. 引入TIS.Imaging.ICImagingControl35.dll

3.ICImagingControl使用这个类控制相机

/// <summary>
/// 相机控制
/// </summary>
public ICImagingControl _ic_imaging_control = new ICImagingControl();//设置不把图片显示在控件
_ic_imaging_control.LiveDisplay = false;
//禁止覆盖位图
_ic_imaging_control.OverlayBitmapPosition = PathPositions.None;if (_ic_imaging_control.Devices.Length > 0){int device_count_ = _ic_imaging_control.Devices.Length;for (int i = 0; i < device_count_; i++){if (_ic_imaging_control.Devices[i].Name.Contains(_camer_parameter._camer_name)){_ic_imaging_control.Device = _ic_imaging_control.Devices[i];_camer_name = _ic_imaging_control.Devices[i].Name;}}}

4.采用回调方式取图

CamerTakeImage.CamerTakeImage._camer_take_image_static.Init();
if (CamerTakeImage.CamerTakeImage._camer_take_image_static._camer_name != "")
{_currently_displayed_buffer = null;//创建相机的回调函数_sink = new TIS.Imaging.FrameQueueSink((arg) => CamerCallback(arg), TIS.Imaging.MediaSubtypes.Y800, 5);CamerTakeImage.CamerTakeImage._camer_take_image_static._ic_imaging_control.Sink = _sink;                             
}

5.把图片转成HObject

    /// <summary>/// 相机的回调函数/// </summary>/// <param name="buffer"></param>/// <returns></returns>FrameQueuedResult CamerCallback(IFrameQueueBuffer buffer){DealWithImage.DealWithImage._deal_with_image_static._exit_image = false;DealWithImage.DealWithImage._deal_with_image_static._image.Dispose();HOperatorSet.GenImage1(out DealWithImage.DealWithImage._deal_with_image_static._image,"byte",buffer.FrameType.Width,buffer.FrameType.Height,buffer.GetIntPtr());DealWithImage.DealWithImage._deal_with_image_static._exit_image = true;hswin_image.RefreshWindow();//这句话一定要有，不然取图只有五张if (_currently_displayed_buffer != null){_sink.QueueBuffer(_currently_displayed_buffer);}_currently_displayed_buffer = buffer;return FrameQueuedResult.SkipReQueue;}
