Three dimensional scanning using membrane with optical features

摘要

Various improvements to inflatable membranes for use in three-dimensional imaging of interior spaces are disclosed. These improvements include, among other things, equipping the inflatable membrane with desirable optical features, such as fiducials, optical coatings, etc., that can be used to improve data acquisition.

主权项

1. A device comprising:
an inflatable membrane having a first end with an opening, a second end distal from the first end, and an interior accessible through the opening, wherein the inflatable membrane has an interior surface with one or more fiducials; a supply of a medium coupled to the interior through the opening and configured to inflate the inflatable membrane with the medium; and a three-dimensional scanning system including at least one scanner element disposed within the interior to capture image data from the interior and a processor programmed to calculate a three-dimensional shape of the interior based upon distances from the scanner element to the surface through the medium within a single frame of the image data, wherein the distances are determined using image data from only the single frame, and wherein the processor uses the one or more fiducials to register the single frame of the image data with at least one other frame of image data to resolve particular locations across multiple images in order to provide a single three-dimensional model from the multiple images, thereby providing a digital model of the three-dimensional shape.
