clc; clear all ;
data = imread('Road-Closeup-2104957.jpg') ;
% image([0 1], [0 1],data); % Fix the axis
imshow(data) ;
title('select the red dots') ;
coor = ginput(4) ;
hold on
plot(coor(:,1),coor(:,2),'*w') ;
wont this work? You may fix the axis if you want.

My attached spatial calibration demo may help.
But you're probably going to need the camera calibration capabilities of the Computer Vision System Toolbox: http://www.mathworks.com/products/computer-vision/features.html#camera-calibration

Use what? To run my code, you put it into an editor window and click the green Run triangle on the tool ribbon.
