visual-studio-2010 - 运动检测代码{EDIT}

Question

编辑
Human walk motion Detect链接介绍了如何在带有C++的Visual Studio 2010中使用Opencv 2.3检测人体运动。我下载了源代码motemp9.c以及文本文件walkImgs.txt和output.txt以及 header filter.h，但不了解以下内容。

我很难执行此程序。有人可以帮我澄清这些观点吗？

在motiontemp9.c文件中，主行下的文件不存在。还是这些文件
walkImgs和输出？

if((ReadFP=fopen("walk2.txt", "r")) == NULL) ErrorExit(ER_READ_OPEN);
if((WriteFP=fopen("output2.txt", "w")) == NULL) ErrorExit(ER_WRITE_OPEN);

运行代码时发生以下错误

error C2660: 'cvGetSeqElem' : function does not take 3 arguments
motemp9.cpp(186): error C2227: left of '->rect' must point to class/struct/union/generic type
motemp9.cpp(189): error C2440: '=' : cannot convert from 'CvScalar' to 'int'
1>          No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called
motemp9.cpp(218): error C2664: 'cvCircle' : cannot convert parameter 4 from 'int' to 'CvScalar'
1>          No constructor could take the source type, or constructor overload resolution was ambiguous
motemp9.cpp(220): error C2664: 'cvLine' : cannot convert parameter 4 from 'int' to 'CvScalar'
1>          No constructor could take the source type, or constructor overload resolution was ambiguous

请指导运行此代码需要做什么。

Answer 1

您能不能重新提出第一个问题，因为我真的不明白。

if((ReadFP=fopen("walk2.txt", "r")) == NULL) ErrorExit(ER_READ_OPEN);
if((WriteFP=fopen("output2.txt", "w")) == NULL) ErrorExit(ER_WRITE_OPEN);

这两行只是在运行程序时检查文件是否存在。如果其中之一不存在，则返回ErrorExit

对于第二个问题，在本示例中，

Create the motion history image. This includes converting the image to grayscale, finding the difference between two frames at a time in sequence order, which creates a silhouette image of the layered history of the motion. Implementation

因此，您需要在walk2.txt中放置从自己的视频中提取的图像的路径。
