Overcomes the quality and lighting limitations of the Kinect

Northwestern University engineers have developed a 3-D capture camera that produces high-quality images and works in all environments, including outdoors, overcoming limitations of Microsoft's Kinect. It's also designed to be inexpensive.

The research is headed by Oliver Cossairt, assistant professor of electrical engineering and computer science at Northwestern's McCormick School of Engineering.

Both first and second generation Kinect devices work by projecting light patterns that are then sensed and processed to estimate scene depth at each pixel on the sensor. Although these techniques work quickly, they are less precise than expensive single-point scanners, which use a laser to scan points across an entire scene or object.
