c++ - 当 cvReleaseImage 时 SIGABRT

Question

我想我对指针感到困惑...

Vision vis;
    IplImage* imgB0=cvCreateImage(img_sz, IPL_DEPTH_32F, 1);
    IplImage* imgB1=cvCreateImage(img_sz, IPL_DEPTH_32F, 1);
    //Get next frame
    vis->getFrame();
    imgB0=vis->image;
    usleep(3);
    vis->getFrame();
    imgB1=vis->image;
    cvAddWeighted(imgB0, 1./(float)2., imgB1,1./(float)2.,0,imgB1);
    cvReleaseImage(&imgB0); //<-SIGABRT
    ...

视觉.h:

 class Vision
    {
    public:
        IplImage* image;
...

视觉.cpp:

void Vision::getFrame()
    {
        image = cvQueryFrame(capture);
    }

有什么想法吗？谢谢!

来自 HighGUI Reference Manual :

The returned image should not be released or modified by user.
