Abstract
Three-dimensional models of objects may be generated according to adaptive depth sensing techniques. An imaging device may include a projector that is configured to project light (e.g., infrared light) onto selected portions of a scene, and a depth imaging sensor configured to capture reflections of the projected light. The projector may be used to project points of light onto aspects of a scene having high degrees of variation of depth, color, texture, curvature or other attributes, where an increased number of depth values may be required to accurately depict a profile of an object within a scene, and to avoid projecting light onto aspects of the scene having low degrees of variation of depth, color, texture, curvature or such other attributes, where the profile of the object may be accurately represented by comparatively fewer depth values.
