    void Start()
    {

        {
            // 获取相机设备
            WebCamDevice[] devices = WebCamTexture.devices;

            // 取第一个相机名称
            deviceName = devices[0].name;

            // 创建相机贴图
            webCam = new WebCamTexture(deviceName, Screen.width, Screen.height, 60);
            
            // 
            rawImage.texture = webCam;

            // 相机开启
            webCam.Play();
