Heart Rate Detection Using Camera

Through any standard video camera, it simultaneously measures pulse and breathing rate with unrivaled reliability and accuracy – even when the person is moving.

Whenever the heartbeats, the skin color changes because of the extra blood running through the vessels. These tiny skin color changes are undetectable by the human eye, but the Camera algorithms amplify these color changes to calculate an accurate pulse rate signal by analyzing the frequency of the color changes. For respiration, the camera focuses on the rise and fall of the chest and abdomen. Again, by amplifying these motions via unique algorithms, an accurate breathing rate is calculated. The measurements are completely unobtrusive and no uncomfortable pads or electrodes need to be worn.

The technology works with any skin type. What’s more, it has been proven in real-world tests to be the most accurate contactless technique for measuring vital signs. It can be integrated with low-cost cameras and doesn’t require any specialist knowledge to use – making it ideal for a wide range of applications.

The camera is motion robust. It uses facial tracking to get an accurate reading during motion, for example when the user is moving in front of the camera or the whole environment is moving. This ensures always a pulse and breathing rate can be calculated.

* Contactless and unobtrusive.

* Proven to be as accurate as on-body sensors.

* Simultaneous heart and breathing rate measurements with one camera capable of monitoring multiple people simultaneously.

* Robust to person movement (when supported with sufficient processing power).

* Hygienic, no need for consumables or sensor cleaning.

* Long range (between 1 and 5 meters, depending on camera).
