Depth-sensing Camera Gleans 3-D Information In Bright Sunlight as Well as Darkness
Depth-sensing cameras, such as Microsoft’s Kinect controller for video games, have become widely used 3-D sensors. Now, a new imaging technology invented by Carnegie Mellon University and the University of Toronto addresses a major shortcoming of these cameras: the inability to work in bright light, especially sunlight. The key is to gather only the bits of light the camera actually needs. The researchers created a mathematical model to help program these devices so that the camera and its light source work together efficiently, eliminating extraneous light, or “noise,” that would otherwise wash out the signals needed to detect a scene’s contours.
