----------   这两天在调试opencv的时候，要将从matlab中获取到的摄像机标定好的参数导入到opencv中，并且对Rotation这个3*1向量通过“罗德里格斯变换”转化成opencv中可以使用的3*3的矩阵。但是在调用这个cvRodrigues2（）函数时候，却一直报错，我没有截图，就用文字复述了，报错是：Error：未定义标识符cvRodrigues2（）。   /

error C2061: 语法错误: 标识符“_TCHAR”解决办法： 标识符“_TCHAR”被定义在“tchar.h”头文件中，包含该头文件即可。#include <tchar.h> 在该头文件中定义如下：#ifndef __TCHAR_DEFINED typedef wchar_t _TCHAR; typedef wchar_t _TSCHAR; typedef wchar_t

1. 程序运行，遇见一堆这样的错误，此时并不要头大，仔细看你能看懂的部分。 1）public: __thiscall，表示这个调用函数；  2）Doctor::Doctor(class std::basic_string,class std::allocator >,int,char,class std::basic_string,class std::allocator >,class s

未定义标识符 "_TCHAR"

未定义标识符 "_TCHAR" 表示在编译过程中出现了该错误。为了解决这个问题，你需要添加一条#include <tchar.h> 的语句，这样就可以成功编译了。 _TCHAR 是一种通用字符类型，它有可能是char型，也有可能是wchar_t型，决定它是哪一种的关键在于你的程序是否定义了#define _UNICODE。如果没有定义，_TCHAR 就是char类型，定义了之后就是wchar_t类型。_TCHAR之所以有这种特性，是因为微软制定了这种字符映射规则。使用_TCHAR，你就不需要考虑UNICODE问题了。<span class="em">1</span><span class="em">2</span><span class="em">3</span> #### 引用[.reference_title] - *1* *2* *3* [Debug of OpenCV](https://blog.csdn.net/qq_22855077/article/details/112547613)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v93^chatsearchT3_1"}}] [.reference_item style="max-width: 100%"] [ .reference_list ]
