在MATLAB中从GPS数据创建“热图” [英] Create 'heat map' from GPS data in matlab

问题描述

我有一堆足球比赛的GPS数据（作为裁判）。我想创建一个热图，所以很清楚你在这个领域大部分时间度过的时间。因此，当没有点或点彼此远离时，当有很多点彼此接近并且蓝色时，这意味着红色。

有人在Matlab中如何做到这一点？

解决方案

您可以使用

I have a bunch of GPS-data from a soccer game (as a referee). I would like to create a heat map, so that it is clear where you spent most of the time in the field. So this means a red color when there are a lot of dots close to each other and blue color when there are no dots or the dots are far from each other.

Someone an idea how to do this in Matlab?

解决方案

You can use the dscatter file written by Robert Henson.

Sample example:

addpath(genpath('../src_plot'));

X = randn(1000,1);
Y = randn(1000,1);

dscatter(X, Y, 'plottype', 'image');
colormap('jet')

You can use 'surf', 'mesh', 'contour' instead of image according to what you expect.
