\documentclass{beamer}
\usepackage{ctex} % 使用中文需要添加的包
\begin{document}
    \begin{frame}
        \frametitle{Marker}
        \begin{columns}
            \column{0.5\textwidth}
            \begin{minipage}[c][0.4\textheight][c]{\linewidth}
                \centering
                \includegraphics[width=0.8\linewidth]{../marker-hand.png}
            \end{minipage}

            \begin{minipage}[c][0.4\textheight][c]{\linewidth}
                \centering
                \includegraphics[width=0.8\linewidth]{../marker-keyboard.png}
            \end{minipage}
            
            \column{0.5\textwidth} % remember add this to the other clumn
            \begin{minipage}[c][0.4\textheight][c]{\linewidth}
                \begin{itemize}
                    \item 原理：blabla。
                    \item 优点：blabla。
                    \item 缺点：blabla。
                \end{itemize}
            \end{minipage}

            \begin{minipage}[c][0.4\textheight][c]{\linewidth}
                \centering
                \includegraphics[width=0.8\linewidth]{../marker-camera.png}
            \end{minipage}
        \end{columns}
    \end{frame}
\end{document}

效果图：

ps：关于在latex中使用中文，个人感觉

\usepackage{ctex}

要比

\usepackage{CJK}

好用。
