The polysomnography test (sleep study) is used to diagnose several sleeping
disorders. Sleep study is used to detect sleep disorders such as Insomnia, REM Sleep
Behavior, Insomnia, Restless Leg Movement Syndrome, and Sleep Apnea. It measures
different parameters such as heart rate, level of oxygen in your blood, body position,
brain waves (EEG), breathing rate, eye movement, and electrical activities of muscles.
In the world, 700 million people suffer from sleeping disorders. A wide range of
sensors was attached to the body of the patient to measure the value of different
parameters. However, in 2020, due to the exponential spread of COVID-19 coronavirus
disease, the sleep study centers were closed, and it was very difficult to perform sleep
studies on patients. Therefore, we developed a hybrid model based on deep learning
techniques like Convolutional Neural Network (CNN) and Deep Belief Network
(DBN) architectures. Numerous cameras were mounted in rooms at certain angles,
which provide live surveillance data and record a patient’s movements after a short
periodic interval of time. This research paper concludes that non-contact-based hybrid
models are highly accurate in detecting sleep disorders based on polysomnography
