Welcome reprint, but please keep the author information

when the image processing development environment was previously constructed, an installation package that was compiled by someone else wouldOpenCVinstalled in thec:\python27\lib\site-packagesdirectory, but thisOpenCVno symbol table, cannot beC + +debugging of the code. We useVScompiled byOpenCVreplace it.

first modify opencv python interface engineering, output it to python cv2.pyd

Let it generate debug information:

Compile Build Cv2.pyd file.

Create a python application , write a simple test code:

Import cv2img = Cv2.imread (' f:\\tmp\\cotton.jpg ') cv2.imshow (' Test win ', IMG) cv2.waitkey (0)

Add this python application of the project properties in the enablenative Debug Open.

in the python of the script Imread This line sets breakpoints

F5 Run, in Imread This line breaks down .

press f11 , step in , vs correct access to python the interface function.

Modify the project properties under modules, and put their project output in the c:\python27\lib\site-packages directory. We have a OpenCV library that can be debugged under python !

because we want to debug OpenCV , so you also need to turn off its optimization features:

Get!
