C#使用Aforge调用摄像头拍照的实现附源码

本文主要实现了利用Aforge调用摄像头拍照的实现，源码力求简洁，希望能够帮助到大家
一.新建一个winform应用
二.使用Nuget添加引用

安装下图中红色框住的两个程序包

安装完后发现安装了如下图的程序包，这是因为上述两个程序包存在对其它程序包的依赖。

三、编写程序

1.窗体设计，三个button控件（button1 打开摄像头，button2 关闭摄像头，button 3 抓拍），一个VideoSourcePlayer控件，一个PictureBox控件。（界面如图所示）

2.编写源码

using System;
using System.Drawing;
using System.Windows.Forms;
using AForge.Video.DirectShow;

namespace PictureboxTest
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        FilterInfoCollection vd1;
        VideoCaptureDevice vd2;
        private void Form1_Load(object sender, EventArgs e)
        {

        }
        /// <summary>
        /// 打开摄像头
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void button1_Click(object sender, EventArgs e)
        {
            vd1 = new FilterInfoCollection(FilterCategory.VideoInputDevice);
            vd2 = new VideoCaptureDevice(vd1[0].MonikerString);
            videoSourcePlayer1.VideoSource = vd2;
            videoSourcePlayer1.Start();
        }
        /// <summary>
        /// 关闭摄像头
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void button2_Click(object sender, EventArgs e)
        {
            videoSourcePlayer1.Stop();
        }
        /// <summary>
        /// 抓拍功能
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void button3_Click(object sender, EventArgs e)
        {
            Bitmap bl = videoSourcePlayer1.GetCurrentVideoFrame();
            pictureBox1.Image = bl;
        }
    }
}

3.程序效果

4窗体源码

namespace PictureboxTest
{
    partial class Form1
    {
        /// <summary>
        /// 必需的设计器变量。
        /// </summary>
        private System.ComponentModel.IContainer components = null;

        /// <summary>
        /// 清理所有正在使用的资源。
        /// </summary>
        /// <param name="disposing">如果应释放托管资源，为 true；否则为 false。</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }
