PROJECTION SCREEN FOR SPECULARLY REFLECTING LIGHT

摘要

Examples disclosed herein relate to determining a segmentation boundary based on an image representing an object. Examples include capturing, from an infrared (IR) camera disposed above and pointed at a projection screen, an IR image representing an object disposed between the IR camera and the projection screen, based on an intensity of IR light reflected by the object and the projection screen including a surface to specularly reflect IR light. Examples include determining a segmentation boundary based at least in part on at least one boundary between a first set of IR light intensity values and a second set of IR light intensity values, wherein the segmentation boundary represents at least one outer edge of the object based on the IR image.

1. A computing system comprising:
a projection screen comprising
a first surface to specularly reflect infrared (IR) light, anda second surface to diffuse visible light; a projector assembly to project visible images on the projection screen; and an IR camera disposed above and pointed at the projection screen to capture an IR image representing an object disposed between the IR camera and the projection screen based on an intensity of IR light reflected by the object and the projection screen.
