問題描述

我有一些 C++ 代碼，除了 imread(file) 函數外，OpenCV 一切正常.它正確地找到了文件并加載了名稱，但沒有加載任何數據.

I have some C++ code and everything was working fine with OpenCV except the function imread(file). It was finding correctly the file and loading the name, but it wasn't loading any data.

Mat pattImage = imread(fileName, 0);

在網絡上進行一些研究后，我意識到我處于調試模式，但使用的是 OpenCV 發布庫，而不是調試庫.

After some reaserch on the web I realized that I was in debug mode but with the release OpenCV libraries, instead of the debug ones.

debug library:    opencv_core231d.lib
release library:  opencv_core231.lib

雖然這是典型的愚蠢錯誤，我認為這不應該有任何關系，調試庫應該允許 OpenCV 代碼調試，而發布庫允許更快地執行代碼，但是我不明白為什么 imread 失敗了.

Though it is the tipical stupid error I thought this shouldn't have anything to do, the debug libraries are supposed to allow OpenCV code debugging while the release libraries allow faster execution of the code, but I don't understand why imread was failing.

誰能解釋一下OpenCV中調試和發布庫之間的區別，以及為什么會出現這個錯誤?

Can anybody explain me the differences between debug and release libraries in OpenCV and why this error occurs?

這是一個 OpenCV 錯誤嗎?

推薦答案

我永遠不會厭倦告訴人們Windows 的 C++ OpenCV 接口有最奇怪的錯誤.

I'll never get tired of telling people that the C++ OpenCV interface for Windows has the wierdest bugs.

使用 C 接口編寫一個小測試來檢查它是否有效(cvLoadImage() 等).

Write a small test using the C interface to check if it works or not (cvLoadImage(), etc).

更新:既然您知道 C 接口工作正常，您可以轉到郵件列表并在那里報告此錯誤，或者自己深入研究代碼以找出失敗的原因.

Update: now that you know that the C interface works properly, you can either go to the mailing list and report this bug there or dig into the code yourself to find why it fails.
