This disclosure describes techniques to estimate the depth map of a scene by illuminating the scene with a near-infrared (NIR) dot projector and by using a single NIR camera that captures the resulting dot-matrix image. The use of a single camera and a single dot projector to estimate the depth map of a scene can significantly reduce the complexity, bill of materials, and calibration procedures for various face-based authentication applications.
