Good day,
I am building a project for my degree. I have created a simple neural netowrk to classify images taken from my Pi Cam for an autonomous car.
I am at the piont where i have the trained model and based on the input image iether go FORWARD, RIGHT or LEFT. This is something that seems simple but i am unable to turn on the GPIO of 1sec. For some reason when an image is read it continueously turn on that respective GPIO out command.
I have attached my code if this make sense. i am a begginer.
%% Connect Raspberry Pi 4B & camera Board in Command Window
% mypi = raspi;
% mypi = raspi('192.168.43.157','pi','pi')
% cam = cameraboard(mypi,'Resolution','320x240');
%
%% Algorithm rev2
for i = 1:1
img = snapshot(cam);
% Preproccessing`````````````````````
imgNew = imresize(img,[227 227]); % resize image
[YPred,probs] = classify(trainedNetwork_1,imgNew);
figure(1);
imshow(imgNew)
label = YPred;
title(string(label) + ", " + num2str(100*max(probs),3) + "%");
end
if string(label) == "Forward"%fwd
for W = 1:1
writeDigitalPin(mypi, 5, 1);
writeDigitalPin(mypi, 6, 0);
writeDigitalPin(mypi, 27, 1);
writeDigitalPin(mypi, 22, 0);
pause(0.5);
end
elseif string(label) == "Left"%pivotleft
for Y = 1:1
writeDigitalPin(mypi, 5, 0);
writeDigitalPin(mypi, 6, 1);
writeDigitalPin(mypi, 27, 1);
writeDigitalPin(mypi, 22, 0);
pause(0.5);
end
elseif string(label) == "Right"%pivotleft
for Z = 1:1
writeDigitalPin(mypi, 5, 0);
writeDigitalPin(mypi, 6, 1);
writeDigitalPin(mypi, 27, 1);
writeDigitalPin(mypi, 22, 0);
pause(0.5);
end
end
