【问题描述】：

我使用预构建的 opencv 2.4.9 我在 opencv 2.4.9 中测试图像显示它可以工作，但是对于这个源它有错误？！如果这个错误是我使用 pre-build opencv？做什么不做什么我复制当前文件夹中的xml文件和我的硬件corei5，Radeon ATI图形

                }
            }
        }
    }

这个错误是微软的中断，请帮助我。非常感谢

First-chance exception at 0x75C4B727 in opencv.exe: Microsoft C++ exception: cv::Exception at memory location 0x003CF678.

If there is a handler for this exception, the program may be safely continued.

最后我成功了，我首先为 PDB 错误工具>选项>调试>输出窗口>模块加载消息>关闭，然后我工具>选项>调试>符号>微软符号服务器未检查，然后我 chnge capture.open(-1) ;捕获.open(0);现在通过在opencv itworks中设置，非常感谢
