Measuring objects in 3D using only a camera and video projector

“A group at AIST, Kagoshima University, Hiroshima City University has developed technology for measuring objects in 3D, using only a camera and projector.
With this new method, patterned light is projected onto the object, and the pattern images captured by the camera are processed to measure it’s 3D shape. Because the 3D shape can be measured from a single image, this method can also be used with a high-speed camera.”
