Depth from time of flight camera
First Claim
Patent Images
1. A method comprising:
- receiving at least one image captured for a single frame by a time of flight camera, the image depicting one or more objects in an environment of the time of flight camera;
inputting the at least one image into a trained region detector;
determining, by the trained region detector, one or more regions of interest in the at least one image based on associations between pixels of time of flight images and regions that depict an object of interest in the time of flight images,wherein a region of interest comprises image elements which are predicted to depict at least part of one of the objects; and
computing depth from the one or more regions of interest of the at least one image.

Abstract
Region of interest detection in raw time of flight images is described. For example, a computing device receives at least one raw image captured for a single frame by a time of flight camera. The raw image depicts one or more objects in an environment of the time of flight camera (such as human hands, bodies or any other objects). The raw image is input to a trained region detector and in response one or more regions of interest in the raw image are received. A received region of interest comprises image elements of the raw image which are predicted to depict at least part of one of the objects. A depth computation logic computes depth from the one or more regions of interest of the raw image.

17. A computer storage media storing instructions which when executed by a computing device control the device to:
-
receive at least one image captured for a single frame by a time of flight camera, the at least one image depicting one or more objects in an environment of the time of flight camera; send the at least one image to a region detector, having been trained to learn associations between image elements of time of flight images and regions of interest; determine, by the trained region detector, one or more regions of interest in the at least one image based on associations between pixels of time of flight images and regions that depict an object of interest in the time of flight images, a region of interest comprising image elements which are predicted to depict at least part of one of the objects; and computer depth from the one or more regions of interest of the at least one image. - View Dependent Claims (18, 19, 20)
