Abstract
A an augmented reality (AR) headset includes a depth camera assembly that combines stereo imaging with structured light (SL) to generate depth information for an area of interest. The depth camera assembly includes at least two image capture devices and a SL illuminator and determines an imaging mode based on a signal to noise ratio or spatial variance of images captured by one or more of the cameras. Different imaging modes correspond to different operation of one or more image capture devices and the SL illuminator. The depth camera assembly includes different ranges of signal to noise ratios that each correspond to an imaging mode, and the depth camera assembly configures the image capture devices and the SL illuminator based on an imaging mode associated with a range of signal to noise ratios including the signal to noise ratio of a captured image.
