Abstract: Aspects of the present disclosure include isolating a target scene object from multiple images of a time-of-flight (TOF) sensor. Multiple images from a TOF sensor can be transformed into multiple three-dimensional (3D) point clouds. In each of the multiple 3D point clouds, one or more large planes having a minimal threshold size can be identified. A common 3D point cloud can be generated by aligning rotated and translated point clouds corresponding to at least a portion of the multiple 3D point clouds. The common 3D point cloud can be rotated and translated to have one of one or more large planes identified as a ground plane within a common coordinate system of the common 3D point cloud, and a target object can be isolated.

Abstract: Aspects of the present disclosure include aligning multiple three-dimensional (3D) point clouds into a common 3D point cloud. A first subset of points within a first 3D point cloud generated from one time-of-flight (TOF) view can be associated with a second subset of points within a second 3D point cloud generated from another TOF view based on each point in the first subset of points having a threshold correspondence to a unique counterpart point in the second subset of points. The first subset of points and the second subset of points can be refined, and a relative rotation and translation between the first 3D point cloud and the second 3D point cloud can be determined. The first 3D point cloud and the second 3D point cloud can be aligned within a common coordinate system based on the relative rotation and translation.

Abstract: Aspects of the present disclosure include obtaining images from a time-of-flight (TOF) sensor for determining dimensions of an object including obtaining, from the TOF sensor, multiple images including the object, validating whether the multiple images are taken at desired poses relative to the object, and where the multiple images are validated as taken at the desired poses, providing the multiple images for object dimensioning to compute or display dimensions of the object.
