坚持在opencv中在不同方向实现过滤器 [英] stuck in implementing filters in different direction in opencv

问题描述

更新了我的问题

这与我上一个问题有关（ OpenCV - 坚持解决练习）。因为，建议我使用我的代码建议的方法，我得到以下错误。

  line1.cpp： int main（int，char **）'：
 line1.cpp：34：10：error：'Point2f'未在此范围内声明
 line1.cpp：34：18： ;'before'rgbMat_center'
 line1.cpp：35：10：error：'Mat'未在此范围内声明
 line1.cpp：35：14：error：expected';'before'mRotation60 '
 line1.cpp：36：14：error：expected';'before'mFilter60'
 line1.cpp：37：28：错误：'mFilter60'未在此范围内声明
 line1.cpp：37：39：error：'mRotation60'未在此范围中声明
 line1.cpp：37：59：error：请求'rgbMat'中的成员'size'，它是非类类型'CvMat *'
 line1.cpp：37：65：错误：warpAffine未在此范围中声明
  

我的代码在这里。在我的代码中，我试图创建一个5 * 5的2D矩阵，然后尝试使用openCV的wrap（）以60度的角度旋转5 * 5矩阵。我得到上面显示的错误。我只想在60度旋转5 * 5矩阵。

  double angleDegree = 60; 
 Point2f rgbMat_center（rgbMat.cols / 2.0F，rgbMat.rows / 2.0F）; 
 Mat mRotation60 = getRotationMatrix2D（rgbMat_center，-angleDegree，1.0）; 
 Mat mFilter60; 
 warpAffine（rgbMat，mFilter60，mRotation60，rgbMat.size（））;任何人都可以建议我出错的地方吗？
 
 h2_lin>解决方案
因为Point2f位于 
 
 
  #include opencv2 \core\core.hpp  
 
 
 
和 Point2f rgbMat_center（rgbMat.cols / 2.0F，rgbMat.rows / 2.0F）; 这是错误的。 
 
 
 
 rgbMat是指针，因此必须像 rgbMat-> cols 。
 
Updated my question

Hi it is related to my previous question (OpenCV - stuck in solving an excercise). As, suggested I used the method suggested in my code and I am getting the following errors.
line1.cpp: In function ‘int main(int, char**)’:
line1.cpp:34:10: error: ‘Point2f’ was not declared in this scope
line1.cpp:34:18: error: expected ‘;’ before ‘rgbMat_center’
line1.cpp:35:10: error: ‘Mat’ was not declared in this scope
line1.cpp:35:14: error: expected ‘;’ before ‘mRotation60’
line1.cpp:36:14: error: expected ‘;’ before ‘mFilter60’
line1.cpp:37:28: error: ‘mFilter60’ was not declared in this scope
line1.cpp:37:39: error: ‘mRotation60’ was not declared in this scope
line1.cpp:37:59: error: request for member ‘size’ in ‘rgbMat’, which is of non-class  type ‘CvMat*’
line1.cpp:37:65: error: ‘warpAffine’ was not declared in this scope
my code is here. In my code I tried to create a 5*5 2D matrix first and then tried to rotate the 5*5 matrix in an angle of 60 degree using wrap() of openCV. I am getting the errors showed above. I just want to rotate the 5*5 matrix in 60 degree.
     double angleDegree = 60;
     Point2f rgbMat_center(rgbMat.cols/2.0F, rgbMat.rows/2.0F);
     Mat mRotation60= getRotationMatrix2D(rgbMat_center, -angleDegree, 1.0);
     Mat mFilter60;
     warpAffine(rgbMat, mFilter60, mRotation60, rgbMat.size());
Can anybody suggest where I am going wrong?
解决方案
Because Point2f is in the 

#include opencv2\core\core.hpp

And Point2f rgbMat_center(rgbMat.cols/2.0F, rgbMat.rows/2.0F); this is wrong. 

rgbMat is pointer so it has to be like rgbMat->cols.
