调用OpenCVSharp进行拍照

一、核心代码：

　　

using OpenCvSharp;

using System;

using System.Collections.Generic;

using System.IO;

using System.Linq;

using System.Text;

using System.Threading;

namespace OpenCVDemoService.Service

{

    class CaptureService

    {

      public void DoSomeThing(DateTime? startTime, long count)

        {

            var cap = VideoCapture.FromCamera(CaptureDevice.Any);

            cap.Set(CaptureProperty.FrameWidth, );

            cap.Set(CaptureProperty.FrameHeight, );

            Mat mat = new Mat();

            //while ())

            {

                cap.Read(mat);

                File.WriteAllBytes(@"D:\code\cap\" + DateTime.Now.Ticks + ".png", mat.ToBytes());

            }

            cap.Release();

            cap.Dispose();

        }

    }

}

说明：

需要中使用OpenCVSharp3来实现，使用前请先Nuget。
