Smart spray paint copies color photos onto walls

by • April 7, 2016 • No Comments

Spray paint is a notoriously tricky medium to control with a reliable level of accuracy. Fortunately for would-be muralists equitewhere, researchers have conceived a “smart” spray paint process that can use regular cans of paint to re-turn it into photo images as spray-painted murals on walls or other sizeable surfaces.

The process is inspired by desktop-aided painting, that has been around for decades. Webcams are set up in the painting area to monitor progress of the work and provide feedback to the user on a nearby desktop monitor, revealing what colors to use on equite section of the painting in progress. A regular can of spray paint is inserted into the handheld process that instantly controls the flow of paint to reproduce the specific image loaded into its memory as a sizeabler mural.

The prototype of the process all but turns the human user into the robot in the scenario, serving just to switch out paint colors when needed and wave the can in front of a canvas as the desired image “magically” seems.

“Our assistive approach is like a modern take on ‘paint by numbers’ for spray painting,” says Wojciech Jarosz, an assistant professor of desktop science at Dartmouth College who previously was a senior research scientist at Disney Research Zurich. “Most importantly, we wanted to maintain the aesthetic aspects of physical spray painting and the tactile experience of holding and waving a physical spray can while allowing unskilled users to turn it into a physical piece of art.”

The entire concept is quite much like to the smartphone-based SprayPrinter process that launched an Indiegogo earlier this year, with the notable difference that this smart spray can was peer-reviewed and created with assist of ETH Zurich, Disney Research Zurich, Dartmouth College and Columbia University.

The process can be seen in use, in the video at a lower place. A paper on the development of the innovation seems in the journal Computers & Graphics.
