以下方法（字体除外）可能是一个很好的起点。我试图让事情尽可能简单。

代码

\documentclass[10pt,xcolor=dvipsnames]{beamer}

\usepackage{kerkis}
\usepackage{kmath}


\usecolortheme[named=Blue]{structure}

\setbeamerfont{title}{series=\bfseries}

\setbeamerfont{author}{size=\normalsize}
\setbeamercolor{author}{fg=structure.fg}

\setbeamerfont{date}{size=\small}
\setbeamercolor{date}{fg=structure.fg}

\setbeamerfont{institute}{size=\small}
\setbeamercolor{institute}{fg=structure.fg}



\setbeamertemplate{title page}{%
    {%
    \usebeamercolor[fg]{title}
    \usebeamerfont{title}
        \MakeUppercase\inserttitle
    }
    \par\medskip

    {%
    \color{Blue!30!cyan}
        \rule{\linewidth}{1pt}
    }
    \par\medskip
    
    {%
    \usebeamercolor[fg]{author}
    \usebeamerfont{author}
        \insertauthor
    }\par\smallskip

    {%
    \usebeamercolor[fg]{date}
    \usebeamerfont{date}
        \insertdate
    }\par
    {%
    \usebeamercolor[fg]{institute}
    \usebeamerfont{institute}
        \insertinstitute
    }
}


\title{Title of the talk}
\author{Some Author}
\institute[]{ABC University}
\date{\today}


\begin{document}
\maketitle

% \begin{frame}{My frame}
% Some text
% \end{frame}
\end{document}
