Autonomous drone cameras have been trialed for several years to detect signs of life in disaster zones.<\/p>\n

\"As As long as the upper torso of a human body is visible, the cameras can pick up the tiny movements in the chest cavity that indicate a heartbeat and breathing rate. <\/p>\n

Using new technology, researchers have discovered a computer vision system capable of spotting survivors in disaster zones from a distance of 4 to 8 metres.<\/p>\n

Autonomous drone cameras have been trialled for several years to detect signs of life in disaster zones. Now, in a world-first study, researchers from Adelaide and Iraq have taken this a step further.<\/p>\n

As long as the upper torso of a human body is visible, the cameras can pick up the tiny movements in the chest cavity that indicate a heartbeat and breathing rate. Unlike previous studies, the system doesn't rely on skin colour changes or body temperature.<\/p>\n

The breakthrough is a more accurate means of detecting signs of life, the researchers from the University of South Australia and Middle Technical University in Baghdad said.<\/p>\n

UniSA Professor Javaan Chahl and Dr Ali Al-Naji, the study leaders, made global headlines in 2017 when they showed for the first time that a camera on a drone could measure heart and respiratory rates.<\/p>\n

At the time, their technique was based on detecting changes in the human skin tone and the camera needed to be within three metres of the person.<\/p>\n

The technique was also limited to one pose where the subject stood in front of the drone, not lying prone as it would be in a disaster zone.<\/p>\n

Other techniques using thermal cameras can only detect signs of life where there is a contrast between body temperature and the background, making this difficult in warm environments.<\/p>\n

Thermal cameras are also unreliable where people are wearing insulated clothing, according to the study published in Remote Sensing.<\/p>\n

"This study, based on cardiopulmonary motion, is the first of its type and was performed using eight people (four of each gender) and a mannequin, all lying on the ground in different poses," Prof Chahl said.<\/p>\n

"Videos were taken of the subjects in daylight, up to eight metres away, and in relatively low wind conditions for one minute at a time, with the cameras successfully distinguishing between the live bodies and the mannequin," added Prof Chahl.<\/p>\n

He said the technology could be used to look for signs of life where time is critical, helping first responders in their search to find survivors in disaster zones.<\/p>\n

This system would be ideal for many situations, including earthquakes and floods, nuclear disasters such as Fukushima, chemical explosions, bio attacks, mass shootings, combat search, and rescue or where a plane has crashed in a remote area.<\/p>\n

Current ground-based operations for rescuing survivors in disaster zones include using rescue robots and rescue dogs, which are expensive and hampered by restricted access.<\/p>\n

He said the motion-based system needs additional testing in adverse weather conditions and to ensure accurate readings when bodies are partially obscured.<\/p>\n
