You should protect the \ref-command as follows:



\documentstyle[12pt]{article}

\begin{document}

\section{The Extraction Technique}{\ }
\begin{equation}
id=id
\label{idovergm}
\end{equation}

\begin{figure}[h]
\caption{Equation~\protect{\ref{idovergm}}}    <<< This line changed
\label{idgmvsvgvth}
\end{figure}
