US 11,029,408 B2 · Distance-imaging system and method of distance imaging

Abstract

A distance-imaging system including an illuminating unit that projects a spatially non-uniform pattern of light spots onto objects present in real-world environment, first portion of said pattern having higher density of light spots than second portion of said pattern; at least one camera that captures image of reflections of the light spots from surfaces of the objects; and at least one optical element associated with said camera, wherein first optical portion of said optical element has higher magnification factor than second optical portion of said optical element, reflections of said first and second portions of spatially non-uniform pattern of light spots being differently magnified and/or de-magnified by said first and second optical portions, respectively.

Dependent claims

A distance-imaging system comprising:

an illuminating unit that, in operation, projects a spatially non-uniform pattern of light spots onto objects present in a real-world environment, wherein a first portion of said pattern has a higher density of light spots than a second portion of said pattern;
at least one camera that, in operation, captures an image of reflections of the light spots from surfaces of the objects;
and
at least one optical element associated with the at least one camera, wherein a first optical portion of the at least one optical element has a higher magnification factor than a second optical portion of the at least one optical element, wherein reflections of said first and second portions of the spatially non-uniform pattern of light spots are differently magnified and/or de-magnified in horizontal and vertical directions by said first and second optical portions of the at least one optical element, respectively.

A method of distance imaging, via a distance-imaging system comprising an illuminating unit, at least one camera and at least one optical element, the method comprising:

projecting, via the illuminating unit, a spatially non-uniform pattern of light spots onto objects present in a real-world environment, wherein a first portion of said pattern has a higher density of light spots than a second portion of said pattern;
capturing, via the at least one camera, an image of reflections of the light spots from surfaces of the objects;
and
differently magnifying and/or de-magnifying reflections of said first and second portions of the spatially non-uniform pattern of light spots in horizontal and vertical directions using first and second optical portions of the at least one optical element, respectively, wherein the first optical portion of the at least one optical element has a higher magnification factor than the second optical portion of the at least one optical element.
