3D map of the accident learned to create in the USFebruary 9, 2019
A lot of time can be spent on registration of an accident: while the police arrive, as long as they measure everything thoroughly, record the testimony of the participants, and so on.
All this is often stretched for several hours. During this time, damaged cars standing on the roadway can not only lead to a traffic jam, but also provoke a second accident. In the USA, we have found a way to radically reduce the time spent on documenting all the circumstances of an accident.
The development of the technology was carried out by specialists from Purdue University (Indiana). To reduce the time of documentation, they decided to use drones. It would seem, well, who can surprise with quadrocopters in 2019? However, scientists went further and developed a fundamentally new approach.
With the help of the UAVs, video recordings are made: they fly around the scene from different angles to document everything thoroughly. It also creates about 100 photos at intervals of two seconds. In the future, based on these data, an accurate 3D model of the scene is formed.
It usually takes 5–8 minutes to fly around. At the same time, the traditional method of taking measurements takes 2-3 hours (and this is in advanced America). Thanks to this, it is possible to remove the injured vehicles much faster from the roadway in order to relieve the road and reduce the likelihood of repeated accidents.
The benefits of new technology do not end there. Using the three-dimensional model recreated on the computer, the police can at any time make a virtual circumnavigation of the accident site and make any additional measurements. Moreover, such a three-dimensional map can even be printed on a 3D printer! The study of the materials of the case has never been so clear.
It is equally important that the new technology is already being applied in practice. Sheriff Tippekanu (Indiana County) for 2018 used the drone 20 times to create a virtual map of the crash site. It is too early to talk about the spread of such practices throughout America, but given the advantages of this method, it is unlikely that popularizing such a useful invention will take a long time.
