1. A method comprising:
emitting one or more illumination patterns from a plurality of projectors including:
emitting one or more illumination patterns from a first projector from the plurality of projectors, wherein the one or more illumination patterns from the first projector include a first illumination pattern that illuminates a location on an object; and
emitting one or more illumination patterns from a second projector from the plurality of projectors, wherein the one or more illumination patterns from the second projector include a second illumination pattern that illuminates the location on the object; and
collecting a plurality of object radiations from the location on the object utilizing one or more detecting elements positioned between the first projector and the second projector, wherein collecting the plurality of object radiations includes collecting a first object radiation produced at the location on the object in response to the first illumination pattern and a second object radiation produced at the location on the object in response to the second illumination pattern to estimate the location on the object independently from other locations on the object and to facilitate forming a three-dimensional surface image of the object.
