Wish you could use your Microsoft Xbox Kinect in bright light? Apparently, so did a team of researchers from Carnegie Mellon University and the University of Toronto. The computer scientists looked into why bright light and sunlight cause depth-sensing cameras like the Kinect to fail, and recently presented their findings and solutions at the SIGGRAPH 2015 conference (viaRedOrbit.com) earlier this month.
While current 3D sensors in cameras like the Kinect search for all data, or light points, the researchers have developed an imaging technologythat gathers only the bits of light the camera needs. When a camera does that, it can eliminate extra light or noise. Using a mathematical formula, the program is able to process data from the camera and renders the image, even when it's taken in brighter environments; the formula can work in bright light, reflective or diffused light, or even through smoke.
“We have a way of choosing the light rays we want to capture and only those rays,” says Srinivasa Narashiman, a CMU associate professor of robotics, in a university statement. “We don't need new image-processing algorithms and we don't need extra processing to eliminate the noise, because we don't collect the noise. This is all done by the sensor.”
