openCV cvSaveImage и cvCvtColor crash on android

2013-08-07 2 views

Я работаю над android с версиями 2.3.5 и 4.0.4 с ошибкой обеих версий при выполнении того же кода. Я пытался получить кадр из видео, сохранить его, а затем преобразовать в HSV.openCV cvSaveImage и cvCvtColor crash on android

(я вывесил этот же вопрос на сайте OpenCV here)

Это мой код, и ошибка я получаю.

public void process(){ 
     IplImage orgImg = this.getFrame(2); 
       cvSaveImage(Environment.getExternalStorageDirectory().toString() + "/openCV/orgimg.jpg", orgImg); 
       IplImage hsv = hsv(orgImg); 
    } 

    private IplImage getFrame(int id){ 
      File testfile = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + videoFile); 

      if(testfile.canRead()){ 

       FFmpegFrameGrabber grabber = new FFmpegFrameGrabber(testfile); 
       try { 
        grabber.start(); 
        grabber.setFrameNumber(id); 
        final int height=grabber.getImageHeight(); 
        final int width=grabber.getImageWidth(); 
        IplImage frame = IplImage.create(width, height, 8, 4); 
        frame = grabber.grab(); 
        //grabber.stop(); 
        return frame; 
       } catch (Exception e) { 
        // TODO Auto-generated catch block 
        e.printStackTrace(); 
       } 
      } 
      return null; 
     } 

private IplImage hsv(IplImage orgImg) { 
     // 8-bit, 3- color =(RGB) 
     IplImage imgHSV = cvCreateImage(cvGetSize(orgImg), 8, 3); 
     Log.e(TAG,"hsvThreshold - Image size" + cvGetSize(orgImg)); 
     cvCvtColor(orgImg, imgHSV, CV_BGR2HSV); 

     return imgHSV; 
    }

Вот LogCat я получаю, когда cvSaveImage или cvCvtColor выполняется на устройстве под управлением 4.0.4

Я нашел этот вопрос, это моя теория:

Этот код выполняется через JNI; поэтому, когда я хватаю изображение и устанавливаю его равным другому изображению, он просто передает указатель. Кроме того, поскольку я запускаю свой граббер в функции getFrame, граббер уничтожается, когда изображение возвращается, и по какой-то странной причине память сбрасывается, а переданный указатель становится бесполезным.

Решение проблемы заключается в том, чтобы либо установить граббер как глобальную переменную, чтобы передать граббер в качестве аргумента функции getFrame, либо (странно) выполнить операцию opencv, которая касается памяти перед возвратом изображения (т.е. вызов cvCvSaveimage или cvCvtColor на что-то случайное, даже не должно быть связано с изображением).

Надеюсь, мое объяснение имеет смысл, и я не знаю, следует ли сообщать об этом как об ошибке?
