лазерное сканирование окружающего нас мира развивается стремительнейшим образом:
The basic principle behind the laser technology is simple: A box, with a laser inside, sits on a tripod; as the box slowly rotates 360 degrees, the laser, moving up and down, bounces its beam off whatever is solid in front of it. In so doing, it registers some 50,000 points in space every second. Traditional surveyors might produce a couple of hundred measurements a day, prone to subjectivity and human error. Lasers collect millions of measurements per hour. A scanner can even identify certain materials, determining whether something is, say, made of glass or stone.
Aerial lasers and a hand-held version operate the same way. Combined, they can bring to life as 3-D images entire cities or a mountainside.
удивительнейшей точности, кстати:
So precise are these digital models that they can be used not only to facilitate much needed restoration work of deteriorating monuments but also to recreate them if they are completely destroyed by natural or man-made disasters. In other words, if the Bamiyan Buddhas had been laser scanned before they were obliterated by the Taliban, they could now be reconstructed with unbelievable accuracy.
и сканируют все подряд:
There are also those abandoned sewers, stormwater tunnels and subway tunnels. Day and night, laser scanners that have gone mobile will be deployed into these voids, and bit by pinprick bit, these labyrinths that once confounded, concealed and even consumed trespassers with their disorienting mazes will resolve into total comprehensibility. Every detail will be known to you.
Simultaneously, disembodied limbs out in some vast tract of land will get to work replicating these filigreed abysses. Once completed, it will look like a city eroded down to its subsurface infrastructure. It’ll be the playground for urban explorers who might be looking for more muted thrills and for architects who could no longer wait for the mythical Golden Age of WPA 2.0 to play out their desires.
