所以我是c ++和opencv的新手，现在我正在使用visual studio 2013上的Windows窗体应用程序尝试stitching sample from opencv。这是我的代码：

我第一次尝试使用此代码时出错，但它自行修复（我不知道为什么以及如何）。如果我没记错的话，这一行是System.Runtime.InteropServices.SEHException：
finder = cv::makePtr<cv::detail::SurfFeaturesFinder>();
错误消失后，我试图运行这个程序，它运行得很好，但程序似乎停留在那个“makePtr”行。我的代码中有什么问题吗？
