我是OpenCV和C++的新手。我得到了OpenCV與Microsoft Visual Studio 2008(32位)的合作,並設法讓Filtering Tutorial/Sobel Derivatives和其他教程正常工作。OpenCV級聯分類器教程異常

我已經添加了這些庫添加到鏈接器輸入: opencv_core230d.lib opencv_calib3d230d.lib opencv_contrib230d.lib
我使用他們的教程提供的代碼現在嘗試Cascade Classifier tutorial opencv_features2d230d.lib opencv_highgui230d.lib opencv_legacy230d.lib opencv_ml230d.lib opencv_imgproc230d.lib opencv_video230d的.lib opencv_objdetect230.lib opencv_gpu230d.lib opencv_haartraining_engined.lib
而且我在Visual Studio項目(其中解決方案文件所在)
的主目錄下的XML文件,但我得到以下錯誤,當我運行/調試:
**
First-chance exception at 0x76b1b9bc in OpenCV_CascadeClassifier.exe: Microsoft C++ exception: cv::Exception at memory location 0x002ff1d0..
Unhandled exception at 0x77e315de in OpenCV_CascadeClassifier.exe: Microsoft C++ exception: cv::Exception at memory location 0x002ff1d0..
**
它不顯示一行代碼是錯誤的,但指向我的內存位置,並顯示我反彙編代碼,我不明白。
問:我如何從我的攝像頭讓視頻流在Visual Studio OpenCV的代碼進行溝通?這是問題所在還是我缺少其他東西?
編輯:該錯誤實際上發生在加載級聯的第一行。我曾嘗試將級聯xmls放在不同的地方,但沒有成功。
任何幫助表示讚賞。
嗨dannyxyz22,感謝您的迴應。我調試和代碼似乎在第一次加載xml行抱怨:'if(!face_cascade.load(face_cascade_name)){printf(「 - (!)Error loading \ n」);返回-1; };」 – 2012-03-31 04:28:39
我已經嘗試將xml文件放在4個不同的位置。 (包括兩個Debug文件夾) – 2012-03-31 04:29:39
我也嘗試過爲xml文件指定完整路徑C:\ Users ...等,但我仍然遇到類似的錯誤。 – 2012-03-31 04:38:47
