Contactless
By analyzing face image sequences captured by the camera, contactless pulse rate measurement is achieved.
Hemoglobin in the blood has the property of absorbing light. This changes the intensity of the light according to the heartbeat. VitalBit™ detects changes in NIR light and calculates pulse rate.
VitalBit™ mechanism
1) Determine the subject from the camera image by face detection.
2) Pulse information is detected from the face image.
3) Calculates pulse rate
Measuring pulse rate at night
It is possible to measure pulse rate in a dark environment by irradiating the face with NIR light and photographing the face with NIR camera.
In general, NIR light has a worse S/N of the pulse signal than visible light, but VitalBit™ realizes the pulse rate measurement using the unique signal processing.
Driver monitoring system
Using VitalBit™, it is possible to measure pulse rate of the driver at night.
A single NIR camera can be used for both VitalBit™ and the driver monitoring system.
The function of VitalBit™ can be added without extra investment on hardware.
