没有OpenCV Manager的OpenCV Android

Question

我知道这个问题已在这里被多次询问和回答.但这些解决方案都不适合我:

• 解决方案1
• 解决方案2
• 解决方案3

这是我的代码(来自此页面):

package com.example.helloopencv;

import org.opencv.android.BaseLoaderCallback;
import org.opencv.android.CameraBridgeViewBase;
import org.opencv.android.CameraBridgeViewBase.CvCameraViewFrame;
import org.opencv.android.CameraBridgeViewBase.CvCameraViewListener2;
import org.opencv.android.LoaderCallbackInterface;
import org.opencv.android.OpenCVLoader;
import org.opencv.core.Mat;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.SurfaceView;
import android.view.WindowManager;

public class HelloOpenCVActivity extends Activity implements CvCameraViewListener2 {

    protected static final String TAG = "HelloOpenCV";

    static {
        if (!OpenCVLoader.initDebug())
            Log.e(TAG, "Failed to load OpenCV!");
    }

    private BaseLoaderCallback mLoaderCallback = new BaseLoaderCallback(this) {
        @Override
        public void onManagerConnected(int status) {
            switch (status) {
            case LoaderCallbackInterface.SUCCESS:
                {
                    Log.i(TAG, "OpenCV loaded successfully");
                    mOpenCvCameraView.enableView();
                } break;
                default:
                    super.onManagerConnected(status);
                break;
            }
        }
    };

    private CameraBridgeViewBase mOpenCvCameraView;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        Log.i(TAG, "called onCreate");
        super.onCreate(savedInstanceState);
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
        setContentView(R.layout.activity_hello_open_cv);
        mOpenCvCameraView = (CameraBridgeViewBase) findViewById(R.id.HelloOpenCVView);
        mOpenCvCameraView.setVisibility(SurfaceView.VISIBLE);
        mOpenCvCameraView.setCvCameraViewListener(this);
    }

    @Override
    public void onResume() {
        super.onResume();
        OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_6, this, mLoaderCallback);
    }

    @Override
    public void onPause()
    {
        super.onPause();
        if (mOpenCvCameraView != null)
            mOpenCvCameraView.disableView();
    }

    public void onDestroy() {
        super.onDestroy();
        if (mOpenCvCameraView != null)
            mOpenCvCameraView.disableView();
    }

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

    public void onCameraViewStopped() {
    }

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

我也按照这里的设置.但是,每次我尝试在我的设备中运行代码时(Galaxy Note 2),我总是被要求安装OpenCV Manager包.我可以错过什么吗？有人可以帮帮我吗？

谢谢!

Answer 1

加

mLoaderCallback.onManagerConnected(LoaderCallbackInterface.SUCCESS);

后mOpenCvCameraView.setCvCameraViewListener(this);在的onCreate()

并OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_6, this, mLoaderCallback);从onResume()中删除

如果其他一切都正确完成,这不应该要求OpenCV管理器.

编辑:

如果你把下面的代码放在onResume你的方法中会更好Activity

mLoaderCallback.onManagerConnected(LoaderCallbackInterface.SUCCESS);
