针对你提出的问题“error: 'std::chrono::monotonic_clock' has not been declared”,我将从以下几个方面进行分析和解答: 检查C++标准库版本: std::chrono::monotonic_clock 是在C++14标准中引入的。如果你的代码是在C++11或更早的标准下编译的,那么编译器将无法识别std::chrono::monotonic_clock。 确认std:...
在C++11版里已经没有momotonic_clock了,有steady_clock作为替代。 我是在这里得到解决思路的:c++ - ‘std::chrono::monotonic_clock’ has not been declared - Stack Overflow 所以orb-slam的作者在代码中使用了ifdef来判断用户的C++版本(大概是这个意思): #ifdef COMPILEDWITHC11std::chrono::steady_clock::tim...

相较于steady_clock,system_clock是不稳定的,可能在两次调用之间,系统时间已经被修改了。 steady_clock Class std::chrono::steady_clock represents a monotonic clock. The time points of this clock cannot decrease as physical time moves forward. This clock is not related to wall clock time (for exampl...

std::chrono::system_clock Defined in header<chrono> classsystem_clock; (since C++11) Classstd::chrono::system_clockrepresents the system-wide real time wall clock. It may not be monotonic: on most systems, the system time can be adjusted at any moment. It is the only C++ clock that ha...
