Non-uniform spatial resource allocation for depth mapping

摘要

A method for depth mapping includes providing depth mapping resources including an illumination module, which is configured to project patterned optical radiation into a volume of interest containing the object, and an image capture module, which is configured to capture an image of the pattern reflected from the object. A depth map of the object is generated using the resources while applying at least one of the resources non-uniformly over the volume of interest.

1. A method for depth mapping, comprising:
providing depth mapping resources comprising:
an illumination module, which is configured to project patterned optical radiation into a volume of interest containing an object; andan image capture module, which is configured to capture an image of the pattern reflected from the object,wherein the volume of interest has a depth that varies with angle relative to the illumination and image capture modules; and generating a depth map of the object using the resources while applying at least one of the resources with an optical resolution that varies non-uniformly over the volume of interest, so as to intentionally distort the image responsively to the varying depth as a function of the angle.
