公司做人脸识别产品经常要用到USB摄像头采集人员人脸照片,没有方便的采集程序,我就做了一个方便项目上使用,通过电脑USB摄像头抓拍照片,自动以unix时间命名保存照片文件,可以选择摄像头,选择分辨率,选择照片保存位置,可设置保存的JPG图像文件压缩质量,里面也放了可保存为PNG格式的代码,使用空格键快速拍照,用在几个项目上还是比较好用的。

Bitmap img = vispShoot.GetCurrentVideoFrame();
picbPreview.Image = img;
TimeSpan now = DateTime.UtcNow - new DateTime(1970, 1, 1, 0, 0, 0,0 );
long t = Convert.ToInt64(now.TotalMilliseconds) / 1000;
SaveImageWithQuality(img, string.Format(txt_ImageAddress.Text @"\{0}.jpg", t.ToString()), long.Parse(sizetextBox1.Text.ToString()));
MessageBox.Show("照片保存成功");
//img.Save(string.Format(txt_ImageAddress.Text @"\{0}.jpg", t.ToString()), System.Drawing.Imaging.ImageFormat.Jpeg); MessageBox.Show("保存成功");
//如果不指定文件名,则默认以当前时间戳命名,微软的Image.Save方法保存到图片压缩质量为75,不加jpeg后缀名则以PNG格式保存,或者Savepath,System.Drawing.Imaging.ImageFormat.Png
