In 2016 there were more than 7 million car crashes reported by police in the United States alone. After making sure all passengers are taken care of, emergency responders have to collect evidence from what may be a crime scene. This process used to take hours, but police departments are turning to a new technology to speed things up: drones. The use of drones has reduced the time it takes to map a crash scene from hours to minutes. Using a technique called photogrammetry, aer...ial scans can then be used to create a 3D model of the crash scene, which can be reviewed later as evidence. Police departments across the US have been rapidly adopting drone technology, and new research from Purdue University shows how effective these flying cameras can be when it comes to clearing roads after a car crash. #DronesForGood Learn more about their research here:
