我试过调试但没有进展。当我也检查haarcascade目录时，我没有找到任何关于汽车检测的xml文件。所以任何帮助我都会感激不尽。代码在下面
I have tried debugging but no progress. When I also checked in the haarcascade directory I didnt find any xml file about car detection. So any help I will be grateful. the code is below
#include <stdio.h>
#include <cv.h>
#include <highgui.h>

推荐答案
A few things that I can identify without looking too hard:
- The precompiled header choice is not set correctly in the project (which gives the missing PCH spec messages)
- The stdafx.h include should be the first one in the list of includes.
- This won’’t compile. A #include with nothing to the right is illegal.
- It might be a good idea to initialize capture and frame to NULL or nullptr in the declaration.
- What do you anticipate the \"while(1);\" will do?
I know a little C++ but am not an openCV user; I’’m sure other indiscretions exist.
