运行openCV/samples/cpp/lkdemo.cpp时出错

Question

我正在尝试运行基于OpenCV的Lucas kande代码：

OpenCV/samples/cpp/lkdemo.cpp

我正在使用

opencv 3.0 version 
Visual studio :2012
Platform: x64

我可以通过提供*.avi输入来运行代码。我可以将输出看作是相同的输入。我看不到跟踪点/箭头。我可以在我的控制台上看到以下消息：

This is a demo of Lukas-Kanade optical flow lkdemo(),
Using OpenCV version 3.0.0
It uses camera by default, but you can provide a path to video as an argument.

Hot keys:
        ESC - quit the program
        r - auto-initialize tracking
        c - delete all the points
        n - switch the "night" mode on/off
To add/remove a feature point click it

Corrupt JPEG data: 6 extraneous bytes before marker 0xdb
Corrupt JPEG data: 28 extraneous bytes before marker 0xdb
Corrupt JPEG data: 6 extraneous bytes before marker 0xdb
Corrupt JPEG data: 2 extraneous bytes before marker 0xdb
Corrupt JPEG data: 2905 extraneous bytes before marker 0xd5
Corrupt JPEG data: 1170 extraneous bytes before marker 0xd2

当我给任何一个输入r/c/n时，代码就会崩溃。谁能告诉我怎样才能在屏幕上看到跟踪输出。

Answer 1

试着使用“原样”的代码。

在namedWindow( "LK Demo", 1 );之后添加waitKey(1000);

所以它变成了，

namedWindow( "LK Demo", 1 );    
waitKey(1000);     
setMouseCallback( "LK Demo", onMouse, 0 );

之后尝试构建。
