US 2017/0374352 A1 · DEPTH IMAGE PROVISION APPARATUS AND METHOD

Abstract

Apparatuses, methods and storage media for providing a depth image of an object are described. In some embodiments, the apparatus may include a projector to perform a controlled motion, to project a light pattern on different portions of the scene at different time instances, and an imaging device coupled with the projector, to generate pairs of images (a first image of a pair from a first perspective, and a second image of the pair from a second perspective), of different portions of the scene in response to the projection of the light pattern on respective portions. The apparatus may include a processor coupled with the projector and the imaging device, to control the motion of the projector, and generate the depth image of the object in the scene, based on processing of the generated pairs of images of the portions of the scene. Other embodiments may be described and claimed.

Dependent claims

An apparatus for providing a depth image of an object in a scene, comprising:

a projector to perform a controlled steering of a light pattern on different portions of the scene at different time instances;
an imaging device coupled with the projector, to generate pairs of images of the different portions of the scene in response to the projection of the light pattern on respective portions, wherein to generate pairs of images includes, for a portion of the scene, to acquire a first image of a pair from a first perspective, and acquire a second image of the pair from a second perspective, wherein the first and second perspectives are different perspectives;
and
a processor coupled with the projector and the imaging device, to control the steering of the light pattern, and generate the depth image of the object in the scene, based at least in part on processing of the generated pairs of images of the portions of the scene.

1 more element

A computing device-implemented method for providing a depth image of an object in a scene, comprising:

causing, by a computing device, a projector to perform a controlled steering, to project a light pattern on different portions of the scene at different time instances;
receiving, by the computing device, pairs of images of the different portions of the scene generated by an imaging device coupled with the projector, in response to the projection of the light pattern on respective portions, including, for a portion of the scene, receiving a first image of a pair acquired from a first perspective, and receiving a second image of the pair acquired from a second perspective, wherein the first and second perspectives are different perspectives;
processing, by the computing device, the generated pairs of images of the portions of the scene;
and
generating, by the computing device, the depth image of the object in the scene, based at least in part on a result of the processing.

2 more elements

One or more non-transitory computing device-readable media having instructions for providing a depth image of an object in a scene stored thereon that, in response to execution on a computing device, cause the computing device to:

cause a projector to perform a controlled steering, to project a light pattern on different portions of the scene at different time instances;
receive pairs of images of the different portions of the scene generated by an imaging device coupled with the projector, in response to the projection of the light pattern on respective portions, including, for a portion of the scene, receive a first image of a pair acquired from a first perspective, and receive a second image of the pair acquired from a second perspective, wherein the first and second perspectives are different perspectives;
process the generated pairs of images of the portions of the scene;
and
generate the depth image of the object in the scene, based at least in part on a result of the processing.
