“One of the most significant uses of 3D scanning in the years to come will not be by humans at all but by autonomous vehicles,” notes Geoff Manaugh of New York Times Magazine. And to give us a sense of just what sort of scanning these vehicles deal with on their drives, two architectural designers, Matthew Shaw and William Trossell, strapped a laser scanner to a Honda CR-V, and went exploring.
Today, self-driving cars find their way around streets, other vehicles, and roadblocks by way of a technology known as “lidar,” a combination of “light” and “radar.” By sending out nearly a million bursts of light per second, all imperceptible to the human eye, cars are able to sense their surroundings. But not only are they able to sense, but these autonomous vehicles actually “capture” their environments, meaning they effectively recreate a three-dimensional model of a scene — one that continues to evolve and adapt to the ever-changing location.
ScanLAB’s recent project, to some extent, attempts to recreate the car’s lidar point of view for human appreciation, with pretty incredible results. “The London that their work reveals is a landscape of aging monuments and ornate buildings, but also one haunted by duplications and digital ghosts,” Manaugh writes. “The city’s double-decker buses, scanned over and over again, become time-stretched into featureless mega-structures blocking whole streets at a time. Other buildings seem to repeat and stutter, a riot of Houses of Parliament jostling shoulder to shoulder with themselves in the distance. Workers setting out for a lunchtime stroll become spectral silhouettes popping up as aberrations on the edge of the image. Glass towers unravel into the sky like smoke.”
But it’s more than aesthetics. As the architects note, not only do the laser scans reveal how far technology has come, but also, how far it has yet to go in creating accurate representations of a car’s whereabouts. But until these autonomous vehicles can see just as we can, we should enjoy their view — it’s pretty amazing.
