Panasonic Contactless Vital Sensing (CVS)

2017: Announcement

In April, 2017 Panasonic announced use of technology of remote measurement of heart rate for the image from cameras. Development received the name Contactless Vital Sensing (CVS).

The operation principle of CVS is based on reflection power of human skin which is directly connected with intensity of blood circulation. The last, in turn, changes taking into account heartbeat force. This dependence is also caught by new technology which, analyzing the picture from the video camera, outputs information on pulse. And it is possible to carry out the analysis on any section of skin, having pointed at it the camera. The example of work of technology is given on video:

According to developers, for remote calculation of frequency of blows of heart it is possible to use even the smartphone camera. The technology will find application in medicine and sport. In the latter case CVS is already involved.

Contactless Vital Sensing was used on a tournament on golf of Open Golf Championship 2017 which took place from April 20 to April 23 in Japan. Especially for this action the video cameras capable to precisely calculate  the frequency of heartbeat of athletes at distance were created. This information gives to dramatic character competitions as allows fans to see that nervousness that is tested inside by players quiet externally.

Panasonic says that the technology can determine heart rate almost with the same accuracy which is reached by medical devices.

The basis for Contactless Vital Sensing is developed in Kyoto University. Scientists of this organization created the system of the millimetric radar of an expanded range which traces a chaotic set of the signals proceeding from each person. The special algorithm isolates the necessary signals (in a case with CVS it is heart beat) from general "noise" and processes them.^[1]
