    namedWindow("left", 1);  
    cvShowImage("left", img1);  
    namedWindow("right", 1);  
    cvShowImage("right", img2);  
    namedWindow("disparity", 1);

    waitKey();  
    imwrite("sgbm_disparity.png", disp8);

}

strFileName1,2 是读入的两个图像，本意是想弄读两个图像然后做视差图显示的。

    IplImage * img1 = cvLoadImage((LPTSTR)(LPCTSTR)strFileName1,0);

用LPTSTR，然后单步调试跟踪一下

字符串转换不建议这样 (LPSTR)(LPCTSTR)， UNICODE下有问题 文件打开 加载一般应该判断是否成功 代码不长， 设置断点 单步调试运行

请在Debug模式下单步执行一下看看
