# Tikz for drawing box flowchart

how can I draw something like this in Latex? I couldn't find anything in tikz examples....

• Welcome to TeX.SX. Questions about how to draw specific graphics that just post an image of the desired result are really not reasonable questions to ask on the site. Please post a minimal compilable document showing that you've tried to produce the image and then people will be happy to help you with any specific problems you may have. See minimal working example (MWE) for what needs to go into such a document. – Stefan Pinnow Jan 22 '19 at 18:47

As Stefan Pinnow pointed out, the purpose of this site is not to convert screen shots into LaTeX code. However, for newcomers sometimes exceptions are made. I hope that this gives you enough motivation to look up these things in the manual and/or examples on this and other sites.

\documentclass[tikz,border=3.14mm]{standalone}
\begin{document}
\begin{tikzpicture}[box/.style={on chain,join,draw,minimum width=7cm,minimum height=1cm,
align=center},start chain=going below,every join/.append style={-latex},
\node[box] (a) {Alignment};
\node[box] (b) {Tracking};
\node[box] (c) {Classification};
\node[above=3mm of a.north west,xshift=3mm] (l) {Fusion};
\begin{scope}[on background layer]
\node[fbox,fit=(a|-l.north) (c),inner xsep=3mm] (f1){};
\end{scope}
\node[above=1.5cm of f1.north west,anchor=west,minimum width=2.5cm,minimum
height=1cm,fbox] (1) {Sensor 1};
\node[above=1.5cm of f1.north east,anchor=east,minimum width=2.5cm,minimum
height=1cm,fbox] (N) {Sensor $N$};
\draw[dashed,ultra thick,shorten >=2mm,shorten <=2mm] (1) -- (N);
\foreach \X in {1,N}
{\draw[-latex] (\X) -- (f1.north-|\X.center) node[fill=white,pos=0.5]{Raw Data};}
\end{tikzpicture}
\end{document}
