1. Introduction
이 문서에서는 OpenCvSharp4, webcam을 이용해 영상을 캡쳐하는 방법을 알아본다. Video 재생 시와 마찬가지로 프레임 단위로 화면을 갱신한다. 사용 중인 카메라에 따라 지원하는 프로퍼티가 달라 카메라 설정 시 확인이 필요하다.
2. Example
간단한 윈폼 프로젝트를 하나 만들어 테스트를 수행하였다. 디자인은 다음 이미지와 같다.
using OpenCvSharp;
using System.Management;
namespace UsingWebcam;
public partial class Form1 : Form
{
private VideoCapture _videoCapture;
private readonly SynchronizationContext _syncContext;
private volatile bool _isStop = false;
public Form1()
{
InitializeComponent();
_syncContext = SynchronizationContext.Current!;
_videoCapture = new VideoCapture();
WebcamList.Items.AddRange(GetImageDevices());
if (WebcamList.Items.Count > 0)
WebcamList.SelectedIndex = 0;
StartButton.Click += StartButton_Click;
StopButton.Click += StopButton_Click;
}
private void StartButton_Click(object? sender, EventArgs e)
{
// 카메라 열기
_videoCapture.Open(WebcamList.SelectedIndex);
// 프레임 크기 조절 시 카메라 다시 연결. 최초 연결할 때만 설정
_videoCapture.Set(VideoCaptureProperties.FrameWidth, (int)FrameWidth.Value);
_videoCapture.Set(VideoCaptureProperties.FrameHeight, (int)FrameHeight.Value);
var worker = new Thread(Worker)
{
IsBackground = true
};
worker.Start();
}
private void StopButton_Click(object? sender, EventArgs e) => _isStop = true;
private void Worker()
{
_isStop = false;
// OpenCvSharp 제공 window
var videoWindow = new Window("Video");
while (!_isStop)
{
SetCameraParams();
// Frame 단위 재생
using var frame = new Mat();
_videoCapture.Read(frame);
videoWindow.ShowImage(frame);
// 카메라에 설정된 Fps 값만큼 wait
Cv2.WaitKey((int)Math.Round(1000 / _videoCapture.Fps));
}
videoWindow.Close();
}

foreach (var device in searcher.Get())
deviceNames.Add(device["Caption"].ToString()!);
return [.. deviceNames];
}
// 카메라에 따라 적용 가능한 설정이 다를 수 있음

}, null);
if (_videoCapture.Exposure != exposure)

if (_videoCapture.Brightness != brightness)
_videoCapture.Brightness = brightness;
if (_videoCapture.Contrast != contrast)

if (_videoCapture.Hue != hue)

if (_videoCapture.Saturation != saturation)
