Ran in:
I have a robot and wall obstacles. My robot has binary sensors which can detect obstacles which are directly in front of them. The wall obstacles have an unclosed shape which is challenging cause with closed I could assume it's polygon. I want to find a way(Matlab command) to tell me if the line(vector) is in the shape or on its edge or not.
Here is my obstacle shape:
%Obstacle Parameters
Points = [[6.5 4.5];
[4.5 4.5];
[4.5 2.5];
[1.0 2.5];
[1.0 6.0];
[3.0 6.0];
[3.0 7.5];
[1.5 7.5];
[1.5 8.5];
[5.0 8.5]];
%Find Obstacle Points
Obstacle_Points = [];
for i = 1:9
ang = atan2(Points(i+1 , 2) - Points(i , 2) , Points(i+1 , 1) - Points(i , 1));
if (ang == pi/2 || ang ==-pi/2)
y = linspace(Points(i , 2) , Points(i+1 , 2) , 100);
x = Points(i , 1) * ones(1 , 100);
Obstacle_Points = [Obstacle_Points ; [x' , y']];
else
x = linspace(Points(i , 1) , Points(i+1 , 1) , 100);
y = Points(i , 2) * ones(1 , 100) ;
Obstacle_Points = [Obstacle_Points ; [x' , y']];
end
end
axis equal
line(Obstacle_Points(:,1) , Obstacle_Points(:,2) , 'LineWidth' , 2 , 'color' , [0.8500 0.3250 0.0980]); xlim([0 7]); ylim([0 10]);
