杂记5--一些oponcv相关的坑

Posted 2023-03-02 鸿_H

1、坑1

error: ‘accumulate’ was not declared in this scope; did you mean ‘cv::accumulate’?

解决方式，添加头文件

#include <numeric>

参考：https://github.com/rpng/calc/issues/8

2、坑2

error: ‘CV_GRAY2RGB’ was not declared in this scope
  457 |     cv::cvtColor(imTrack, imTrack, CV_GRAY2RGB);

解决：在报错文件上添加头文件 #include<opencv2/imgproc/types_c.h>

参考：https://wenda.ncnynl.com/article/5

3、坑3

error: ‘iota’ is not a member of ‘std’
166 | std::iota(sort_idx.begin(), sort_idx.end(), 0);

解决方式：在对应文件中添加
#include

4、坑4

error: ‘CV_EVENT_LBUTTONDOWN’ was not declared in this scope
   41 |     if (event == CV_EVENT_LBUTTONDOWN) 

解决方式：将CV_修改为cv::

// if (event == CV_EVENT_LBUTTONDOWN) 
if (event == cv::EVENT_LBUTTONDOWN)
