在我的大学里，他们要求我们在海报的标题中使用这个图形，
还有最下面的这个。

答案1
页眉中的图像可以与\node[below,inner sep=0pt] at (0,{\paperheight/2}) {\includegraphics[width=\paperwidth,height=5cm]{example-image-a}};页脚一起放置，方法类似。
相关代码insertlogo已被删除。
该选项titletotopverticalspace=7cm已提供给命令\maketitle。
注意，问题中有\LARGE{<text>}。最好写成{\LARGE <text>}，例如在\bfseries 加粗程度超出预期。
