Load Map text file with X and Y coordinates, want to plot those coordinates and plot the vehicle dimensions inside the plot

MATLAB Version 9.7 (R2019b)

Hi,

working on an automonous vehicle project, where the vehicle will drive through the plotted area in the text file.

i have a text file with X and Y coordinates (M1_layout.txt), have the dimensions of a vehicle which will drive through the X and Y coordinates.

I Want to plot out a figure of X & Y coordinates (with dots or crosses), also to add the vehicle inside that plot as it will be driving through the X and Y coordinates.

So far i know how to load the text file, parse the text file and when attempting to plot the text file getting a blank figure.

M-file script code:

dx_snr = 0.0; % Longitudinal distance between the center of the vehicle and the t antenna center point
dy_snr= 2.125; % Lateral distance between the center of the vehicle and the t antenna center point
nominalR = 0.75; % Nominal wheel radius
dx_wheel = 3.85; % longitudinal distance of the wheel centre
dy_wheel = 2.266; % lateral distance of the wheel from centre

t_map ='M1_layout.txt';

Map = GroundMap();
Map.LoadMap( t_map );

MS = NurbsSet;
RS = MS.Route;
L = RS.Size;
%% Display T Map
me = Map.Export();
nn = length(me);
map_pos = reshape([me.pos],2,nn)';
figure('Name','T Map Locations');
plot(map_pos(:,1),map_pos(:,2),'r.'); %X axis is all column 1, Y axis all column 2, red dots
axis equal; 
for ii = 1:L
	NN = RS.GetMotion(ii);
	pos = NN.GetPose(s);
	hold on;
    plot(pos(:,1),pos(:,2),'b-'); % X axis is all column 1, Y axis all column 2, blue dash
    hold off; 
end

What is this function GroundMap?

[Max Wright]

• GroundMap class:- is used for holding and accessing t maps (M1_layout.txt)
• NURBS class:- handles the curve functions, such as getting length, position, pose, velocity, etc. However, as a NURBS it works from progress values i.e. from 0 to 1.
• NURBSset class:- allows you to load & filter routes from the M1_layout.txt file. You can access them and/or generate a routing set, which produces lanes, transitions and lane-changes

Note: these are MATLAB MEX wrappers mentioned

T = readtable('M1_layout.txt') ;
pos = [T.(2) T.(3)] ;
plot(pos(:,1),pos(:,2),'.r')

Thanks, that worked, refer to attached image.

I read and found out 'readtable' function was only for csv loading.
