Digital camera system measures cardiopulmonary data from animals

摘要

A new camera-based system developed by a team of international researchers remotely monitors the cardiopulmonary signals of animals, suggesting the possibility of gathering data without capturing or restraining subjects. In the paper, A Pilot Study for Estimating the Cardiopulmonary Signals of Diverse Exotic Animals Using a Digital Camera, (bit.ly/VSD-CPS), the researchers describe a camera system tested on several animal types that extracts cardiopulmonary data by monitoring chest and abdomen movement. A Nikon (Tokyo, Japan; www.nikon.com) D610 camera with Nikon AF-S NIKKOR 200-500 mm f/5.6E VR lens, mounted on a tripod from 3 to 40 m away from the subject animal, captured 1920 x 1080 video at 30 fps. Each video was one to three minutes long and saved in QuickTime format. Repeated videos were taken of each subject animal.
