Active 3D Reconstruction
************************

Active 3D reconstruction methods calculate 3D data with additional active light source, mostly eye-safe infrared, with or without particular patterns, such as Gray code, speckles patterns, etc. In this Chapter, main methods for active 3D reconstruction are reviewed.
