safety hello everyone today I'm going to
explain the code of dri
drowsiness and here as you can see on my
screen this is the code for driver
drowsiness first I'm going to explain
what and all Technologies we have used
and what we have imported we have used
open CV and we have imported CV2 over
here and uh we have also imported
numai we have also imported scipi and P
game now I'm going to explain the this
function I aspect ratio
function so basically in this it
calculates the uh ratio of i ph and
everything and this is done using the
ukan
distance uh now I'm going to
explain uh the classifiers that we have
used used here uh we have used various
classifiers the reason of using these
classifiers is to detect the face it's
to detect the front face to detect the
left eye and to detect the right eye so
the classifiers that we have used over
here is
hardcard hardcard frontal face
classifier hardcard left eye classifier
hardcard right eye
classifier now uh I'll explain this
function that helps setting thresholds
and initializing the
counters so here we defined uh this is
where we Define the constants for the I
aspect ratio thresold and consecutive
frame count to identify the drowsiness
and here is where we initialize uh as
you can see here here is where we
initialize the frame counter and alarm
plane
flag
uh now I'll tell how we initialize video
stream and P game so this code that you
see over here is used to initialize the
video stream to capture Real Time video
and to set up P game for playing alarm
sounds
uh now I'll show how we detect
I in real
time so here is a loop this is the main
Loop where we do uh I identification in
real time so inside this Loop we read
frames from the video stream convert
them to gray scale and detect faces for
each detected face we detect eyes and
compute their eye aspect ratio
now I'll tell you what we do to
continuously monitor the I aspect ratio
so this part of code that you see here
this is what we use to monitor the I
aspect ratio for the both eyes
continuously and here's where the alarm
sound plays if it detects that uh I
aspect ratio is very less basically say
that the driver is drowsy so this is
where the alarm
rings now to display that the driver is
drowsy uh and displaying the video frame
and all that uh we use this part of the
code to show our results and now I'm
going to show the sample of a
project show you the output
it is
analyzing and taking in many frames
yes that's the alarm sound and I'll
close it
now so that's it for the driver
drowsiness my name is Fatima and I'm
excited to show our project driver
drowsiness detection I will be talking
about the solution and literature review
of this portion of the BPD so let's dive
into our solution here the proposed
solution is a drive drowsiness detection
system that utilizes a combination of
machine learning and computer vision
techniques this system will monitor the
driver's expressions and eye movements
head positions in real time using a
camera mounted onto the dashboard so by
analyzing these parameters the system
will identify signs of
drowsiness coming to literature review
we are going to analyze certain
expressions in order to detect the
driver drowsiness so coming to facial
feature analysis here research IND
indicates that changes in facial
expressions like yawning and eye closure
are strong indicators of drowsiness
certain techniques we use here are hog
that stands for histogram of oriented
gradients and CNN convolutional mural
networks next is eye closure detection
so the percentage of eye closure is a
widely used metric and certain
techniques and algorithms used are while
our Jones next is head position
monitoring so head nodding or tilting is
another significant indicator of drial
drowsiness and certain algorithms we use
here are svm support Vector machines and
K neighbor K nearest neighbors K&N to
classify head
poses now we are going to talk about
multimodal approaches so here we combine
various indicators such as spatial
features eye closure and head position
to improve the accuracy of riness
detection systems and the various me
methodologies we use are data
collection feature extraction model
training realtime detection and a
mechanism
