我正在使用JavaCV，OpenCV的Java接口开发OMR(光学标记识别)应用程序。该应用程序可以很好地运行200张图像，但是此后它无法在我的代码中为IplImage分配内存。当我尝试克隆imgx时出现分配错误并将其分配给imgxc1。您能提出一个针对程序的修复程序吗？ 增加堆大小似乎是一个临时解决方案？

这是初始化代码(发生异常的地方)：

protected boolean init () throws UnableToLoadImage{

imgx = new IplImage();

imgxc1 = new IplImage();

imgxd1 = new IplImage();

imgx = cvLoadImage(path+DR+filename);

if(imgx == null)throw new UnableToLoadImage(path+DR+filename);

//cvSaveImage(“debug/”+filename, imgx);

imgxc1 = cvCreateImage(cvGetSize(imgx), imgx.depth(), imgx.nChannels());

imgxc1 = imgx.clone();//error comes here

imgxd1 = cvCreateImage(cvGetSize(imgx), IPL_DEPTH_8U, 1);

cvCvtColor(imgxc1, imgxd1, CV_BGR2GRAY);

return (imgx != null && imgxc1 != null && imgxd1 != null)?true:false;

}

这是清理代码：

public void release() {

if(imgx != null){

imgx.release();

imgxc1.release();

imgxd1.release();

cvReleaseImage(imgx);

cvReleaseImage(imgxc1);

cvReleaseImage(imgxd1);

}

}

堆栈跟踪：
