摘要

Systems and methods are described for Distification of 3D imagery. A computing device may obtain a three dimensional (3D) image that includes rules defining a 3D point cloud used to generate a two dimensional (2D) image matrix. The 2D image matrix may include 2D matrix point(s) mapped to the 3D image, where each 2D matrix point can be associated with a horizontal coordinate and a vertical coordinate. The computing device can generate an output feature vector that includes, for at least one of the 2D matrix points, the horizontal coordinate and the vertical coordinate of the 2D matrix point, and a depth coordinate of a 3D point in the 3D point cloud of the 3D image. The 3D point can have a nearest horizontal and vertical coordinate pair that corresponds to the horizontal and vertical coordinates of the at least one 2D matrix point.

說明書

FIG. 8 illustrates a flow diagram of an exemplary method 800 for generating an enhanced prediction from a 2D and 3D image-based ensemble model. The method 800 may be implemented on a computing device, such as, for example, any of the computing devices described for FIGS. 1 and 2 herein.

At block 804 a computing device may obtain one or more sets of 2D image(s). The sets of 2D image(s) may include, for example, training image sets, validation image sets, and/or test image sets. Each set may include one or more 2D images or chunks of 2D images as described herein. In certain embodiments, the 2D images(s) may be JPEG images obtained from a computing device having a camera, such as a webcam.

Similarly, at block 814, the computing device may obtain one or more sets of 3D image(s). The sets of 3D image(s) may include, for example, training image sets, validation image sets, and/or test image sets. Each set may include one or more 3D images or chunks of 3D images as described herein. In certain embodiments, the 3D images(s) may be PLY-based images obtained from the same or a different computing device having a 3D sensor.

Either or both of the 2D image(s) or 3D image(s) of blocks 804 and 814 may be obtained from cameras or sensors collocated with the computing device or obtained from a different or remote computing devices, such as described for FIGS. 1 and 2.
