使用子标题包对齐大小不等的图形的标题

Question

我有两个大小不等的图形（图 1 较宽，图 1 较短），我想将两个子图垂直居中对齐，但保持子标题在顶部对齐（请参见附图）。可以使用 subcaption 包来实现这一点，而无需修改图形本身吗？ （图片更新）

%preamble
\usepackage[singlelinecheck=false, aboveskip=-3pt]{subcaption}
%document
       %version1----
            \begin{figure}
            \captionsetup[subfigure]{labelformat=simple, position = top}
            \captionsetup{font={onehalfspacing},skip=-10pt}
            \subcaptionbox{}[0.5\textwidth]{\includegraphics[width=0.5\linewidth]{fig1.pdf}}
            \subcaptionbox{}[0.5\textwidth]{\includegraphics[width=0.5\linewidth]{fig2.pdf}}

        \end{figure}
        \clearpage
       %version2----
        \begin{figure}[hb]
            \captionsetup[subfigure]{labelformat=simple}
            \captionsetup{font={onehalfspacing},skip=-10pt}
                \begin{subfigure}[c]{0.49\textwidth}
                    \caption{}                
                    \includegraphics[width=\textwidth]{fig1.pdf}
                \end{subfigure}
                \begin{subfigure}[c]{0.49\textwidth}
                    \caption{}                
                    \includegraphics[width=\textwidth]{fig2.pdf}
                \end{subfigure}
