Question

我是Opencv的新手。在android应用程序中，opencv工作但在logcat中给出了错误。我怎么解决这个问题？在运行时相机运行但进一步的应用程序我不能做对象识别。我该怎么办？任何资源或文档都有帮助。谢谢。

            </intent-filter>
        </activity>


    </application>

这是我的源代码

public class MainActivity extends AppCompatActivity  implements  CameraBridgeViewBase.CvCameraViewListener2{


    private static final String TAG = "OpenCV Taha Camera : ";
    public static CameraBridgeViewBase cameraBridgeViewBase;
    public TextView screen_info;
    private static final int REQUEST_PERMISSION = 100;


    static {

        if(!OpenCVLoader.initDebug()){
            Log.d(TAG,"OpenCV NOT LOADED.");
        }else {
            Log.d(TAG,"OpenCV Loaded Successfully.");
        }
    }



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        screen_info = findViewById(R.id.screen_info);

        if(ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED){
            ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.CAMERA},REQUEST_PERMISSION);
        }
        cameraBridgeViewBase = findViewById(R.id.camera_screen);
        cameraBridgeViewBase.setVisibility(SurfaceView.VISIBLE);
        cameraBridgeViewBase.setCvCameraViewListener(this);



        screen_info.setText("---No Info Currently---");

    }


    @Override
    public void onResume() {
        super.onResume();
        if(!OpenCVLoader.initDebug()){
            Log.d(TAG,"OpenCV Library NOT LOADED! ");
            OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_3_4_0,this,baseLoaderCallback);
        }else{
            Log.d(TAG,"OpenCV Loaded Successfully");
            baseLoaderCallback.onManagerConnected(LoaderCallbackInterface.SUCCESS);
        }
    }

    private BaseLoaderCallback baseLoaderCallback = new BaseLoaderCallback(this) {
        @Override
        public void onManagerConnected(int status) {
            switch (status){
                case LoaderCallbackInterface.SUCCESS:
                    cameraBridgeViewBase.enableView();
                    break;
                default:
                    super.onManagerConnected(status);
                    break;
            }
        }
    };


    @Override
    public void onCameraViewStarted(int width, int height) {
    }

    @Override
    public void onCameraViewStopped() {
    }

    @Override
    public Mat onCameraFrame(CameraBridgeViewBase.CvCameraViewFrame inputFrame) {
        return inputFrame.rgba();
    }
}
