Page Layout ⇒ How to set de spacing between the text and the image caption to `\baselineskip`?

[lucasmsoares96]

I tried to set everything to `\baselineskip` in the code below, but the space between the text and the image not match with the rest of the text.

Code: Select all

\documentclass[14paper,12pt]{article}
\usepackage{graphicx,lipsum,caption,csquotes,setspace}

\makeatletter
\setstretch{1.5}
\setlength{\intextsep}{\baselineskip}
\setlength{\floatsep}{\baselineskip}
\setlength{\textfloatsep}{\baselineskip}
\setlength{\abovecaptionskip}{0pt}
\setlength{\belowcaptionskip}{0pt}
\setlength{\abovedisplayskip}{\baselineskip}
\setlength{\belowdisplayskip}{\baselineskip}
\setlength{\abovedisplayshortskip}{\baselineskip}
\setlength{\belowdisplayshortskip}{\baselineskip}
\setlength{\jot}{\baselineskip}

\renewcommand\section{
  \@startsection {section}{1}{\z@}
  {-\baselineskip}
  {\baselineskip}
  {\normalfont\normalsize\bfseries}
 }
\makeatother

In the image below, all green rectangles have the same height. But the spacing on top of the image caption is smaller than one `\baselineskip` (yellow rectangle) and the space below is larger than `\baselineskip` (red rectangle). But to my university template, everything should be with the same spacing. How to fix this?
