java 调用电脑摄像头

上面就是调用摄像头的效果.

下面贴带码

首先需要导一个jar包

<dependency>
    <groupId>com.github.sarxos</groupId>
    <artifactId>webcam-capture</artifactId>
</dependency>
然后创建main方法

public static void main(String[] args){
   Webcam webcam = Webcam.getDefault();

   webcam.setViewSize(WebcamResolution.VGA.getSize());

   WebcamPanel panel = new WebcamPanel(webcam);

   panel.setFPSDisplayed(true);

   panel.setDisplayDebugInfo(true);

   panel.setImageSizeDisplayed(true);

   panel.setMirrored(true);

   JFrame window = new JFrame("Test webcam panel");

   window.add(panel);

   window.setResizable(true);

   window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

   window.pack();

   window.setVisible(true);

}
}
