java - 增强现实、立体视觉、Android Studio

Question

我正在开发一个增强现实应用程序。我需要在此应用程序上添加立体视觉以与纸板一起使用，但我没有在此代码上添加立体视觉。有人能帮我吗？我有三个班，我在其中放立体镜，怎么做？

public class ARSimpleApplication extends Application {

    private static Application sInstance;

    // Anywhere in the application where an instance is required, this method
    // can be used to retrieve it.
    public static Application getInstance() {
        return sInstance;
    }

    @Override
    public void onCreate() {
        super.onCreate(); 
        sInstance = this;
        ((ARSimpleApplication) sInstance).initializeInstance();
    }

    // Here we do one-off initialisation which should apply to all activities
    // in the application.
    protected void initializeInstance() {

        // Unpack assets to cache directory so native library can read them.
        // N.B.: If contents of assets folder changes, be sure to increment the
        // versionCode integer in the AndroidManifest.xml file.
        AssetHelper assetHelper = new AssetHelper(getAssets());        
        assetHelper.cacheAssetFolder(getInstance(), "Data");
    }
}

public class ARSimple extends ARActivity {


    private static final int MY_PERMISSIONS_REQUEST_CAMERA = 133;
    /**
     * A custom renderer is used to produce a new visual experience.
     */
    private SimpleRenderer simpleRenderer = new SimpleRenderer();

    /**
     * The FrameLayout where the AR view is displayed.

    private FrameLayout mainLayout;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);      
        setContentView(R.layout.main);

        mainLayout = (FrameLayout)this.findViewById(R.id.mainLayout);

        //if (!checkCameraPermission()) {
            //if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.CAMERA)) { //ASK EVERY TIME - it's essential!
        //  ActivityCompat.requestPermissions(this,
        //          new String[]{Manifest.permission.CAMERA},
        //          MY_PERMISSIONS_REQUEST_CAMERA);
        //}

        // When the screen is tapped, inform the renderer and vibrate the phone
        mainLayout.setOnClickListener(new View.OnClickListener() {

        });
