摘要： The attenuation and other optical properties of a medium are exploited to measure a thickness of the medium between a sensor and a target surface. Disclosed herein are various mediums, arrangements of hardware, and processing techniques that can be used to capture these thickness measurements and obtain three-dimensional images of the target surface in a variety of imaging contexts. This includes general techniques for imaging interior/concave surfaces as well as exterior/convex surfaces, as well as specific adaptations of these techniques to imaging ear canals, human dentition, and so forth.

摘要： Various improvements to inflatable membranes are disclosed for use in three-dimensional imaging of interior spaces based upon distance measurements. These techniques may be used alone or in combination for improved data capture. In one aspect, a device disclosed herein includes an inflatable membrane having a proximal end with an opening, a distal end, and an interior accessible through the opening, wherein the inflatable membrane has an inflation characteristic that is nonuniform, thereby causing the membrane to inflate in a predetermined manner; a supply of a medium coupled to the interior through the opening; and a three-dimensional scanning system including at least one scanner element disposed within the interior to capture data from the interior and a processor programmed to calculate a three-dimensional shape of The interior based upon the data.

摘要： According to one aspect, a method of determining motion of at least one feature present in a plurality of images, the plurality of images captured by a single camera of a scene, each of the plurality of images resulting from light passing through an aperture positioned at a different location for each of the plurality of images is provided. The method comprises determining the motion, in integer pixel units using a first tracking algorithm, of the at least one feature between a first image of the plurality of images and a second image of the plurality of images to obtain an integer pixel measurement of the motion, offsetting the first image and the second image according to the integer pixel measurement, determining the motion, in sub-pixel units using a second tracking algorithm, between the at least one feature in the offset first image and the second image to obtain a sub-pixel measurement, and combining the integer pixel measurement and the sub-pixel measurement to form an estimate of the motion of the at least one feature.
