Sony patents light setup guide to reduce glare in 3D imaging

Sony describes a system that calculates the best angle for polarized light to shine on an object based on its 3D shape. It then guides the user to adjust the light source so that unwanted reflections are minimized.

Why it mattersThis could help improve the accuracy of 3D scanning and computer vision systems by reducing visual noise from shiny surfaces.

In the filing’s own words

The present disclosure relates to an information processing device and a method to make it possible to suppress reflection by a multipath. At a time of polarization imaging, a recommended polarization direction of irradiation light emitted from a light emitting unit is derived according to a shape of an object in a three-dimensional space, and an operation for bringing a polarization direction of the irradiation light closer to the recommended polarization direction is guided. The polarization imaging is an imaging method in which the object irradiated with irradiation light polarized in a first direction is imaged by an imaging unit via a configuration that polarizes in a second direction, the second direction is a direction orthogonal to the first direction or a direction parallel to the first direction, and the recommended polarization direction is a direction in which a specular reflection component of the irradiation light, which is specularly reflected on a plurality of surfaces of the object and incident on the imaging unit, is at least equal to or less than an average. The present disclosure may be applied to, for example, an information processing device, electronic equipment, an information processing method, a program, or the like.

What exactly they claim (claim 1)

1. An information processing device comprising: a recommended polarization direction derivation unit configured to derive a recommended polarization direction of irradiation light emitted from a light emitting unit according to a shape of an object in a three-dimensional space at a time of polarization imaging; and a guide unit configured to guide an operation for bringing a polarization direction of the irradiation light closer to the recommended polarization direction, wherein the polarization imaging is an imaging method in which the object irradiated with the irradiation light polarized in a first direction is imaged by an imaging unit via a configuration that polarizes in a second direction, the second direction is a direction orthogonal to the first direction or a direction parallel to the first direction, and the recommended polarization direction is a direction in which a specular reflection component of the irradiation light, which is specularly reflected on a plurality of surfaces of the object and incident on the imaging unit, is at least equal to or less than an average.
