Hello Sir/Mam,
I am trying to send real time coordinates of tracked ball from MATLAB to Simulink with UDP communication.
This is my code:
vid = videoinput('winvideo',1);
set(vid, 'FramesPerTrigger', 1);
set(vid, 'TriggerRepeat', Inf);
triggerconfig(vid, 'manual');
start(vid);
mdl = 'udpsim';
open_system(mdl);
ball_diameter = 20;
ball_radius = ball_diameter/2;
ball_min_size = round(ball_diameter / 0.07);
gray_threshold = 200;
sat_threshold = 0.2;
ball_color = [190, 190, 190];
localIP = '10.53.126.43';
remoteIP = '10.53.126.43';
u = udpport(remoteIP, 'RemotePort', 51002, 'LocalPort', 51001, 'OutputBufferSize', 1024);
fopen(u);
i=1;
while i<10000
img = imread(vid);
gray_img = rgb2gray(img);
sat_img = rgb2hsv(img);
sat_img = sat_img(:,:,2);
gray_mask = gray_img > gray_threshold;
sat_mask = sat_img > sat_threshold;
mask = gray_mask & sat_mask;
mask = bwareaopen(mask, ball_min_size);
stats = regionprops(mask, 'Centroid');
if isempty(stats)
ball_coord = [-1, -1];
else
ball_centroid = stats(1).Centroid;
ball_coord = [ball_centroid(1), ball_centroid(2)];
end
write(u, sprintf('[%f,%f]', ball_coord(1), ball_coord(2)));
end
stop(vid); %#ok<UNRCH>
delete(vid);
fclose(u);
Simulink Model:
Problem:
When I run Simulink model 1st then Matlab code not run and If I run Matlab code 1st, I am getting this error
Expected input number 1 to match one of these values:
'byte', 'datagram', 'IPV4', 'IPV6', 'LocalHost', 'LocalPort', 'Timeout', 'ByteOrder', 'OutputDatagramSize', 'EnablePortSharing'
The input, '10.53.126.43', did not match any of the valid values.
How to run simultaneously both ?
Please Help! I will be very grateful to you...
