C++ 在OpenCV中使用cv:：imwrite时出现运行时错误

我正在使用OpenCV 2.3.1。我的语言是C++。 如果我像这样硬编码输出文件的名称，那么imwrite工作得很好

cv::imwrite("/home/peter/BlendedInterpolatedPlane.jpg", srcnorm);

cv::imwrite(outputFileName.c_str(), srcnorm);

但是，当我尝试将输出文件名作为如下字符串传递时，会出现运行时错误

cv::imwrite("/home/peter/BlendedInterpolatedPlane.jpg", srcnorm);

cv::imwrite(outputFileName.c_str(), srcnorm);

还是像这样

cv::imwrite(outputFileName, srcnorm);

虽然没有编译器错误

outputFileName声明为std:：string并包含输出文件名

堆栈跟踪如下所示

非常感谢您的帮助，

彼得我发现了这个问题。输出文件名的后缀无效。一旦我解决了这个问题，它就可以正常工作了

cv::imwrite(outputFileName, srcnorm);

其中outputFileName的类型为std:：string
