20140272221 | INFLATABLE MEMBRANE FOR FLUORESCENT IMAGING AND IMPROVEMENTS IN DYE MATERIALS - An inflatable membrane for use with a three-dimensional (3D) scanning system configured to measure signal intensity of a first and a second wavelength of light may include a matrix material, a pigment for opacity, and a fluorescent material that is transparent to the first and the second wavelengths of light. The first and second wavelengths of light may be ranges of wavelengths. The matrix material may include a silicone, and the pigment for opacity may include a carbon black. The 3D scanning system may be configured to scan anatomical cavities, such as the human ear canal. | 09-18-2014 |
20140276005 | Fiducial Markers for Fluorescent 3D imaging - In some example embodiments, there may be provided an apparatus. The apparatus may include a balloon membrane including an opening, an exterior surface, and an interior surface, the interior surface including one or more fiducial markers forming a pattern detectable by a scanner imaging the interior surface of the inflatable membrane. Methods and apparatus, including computer program products, may also be provided. | 09-18-2014 |

20110007138 | GLOBAL CAMERA PATH OPTIMIZATION - Disclosed herein are various techniques for improving global path optimization in a system that uses camera path for three-dimensional reconstruction. A subset of frames of data for the global path, the key frames, may be used to reduce the computational complexity of the optimization, while preserving full three-dimensional detail in the optimized model by relating other measurements to the optimized key frame path. | 01-13-2011 |

20130329020 | HYBRID STITCHING - In a system or method where three-dimensional data is acquired as a sequence of frames of data along a camera path, disparate sequences are related to one another through a number of geometric stitches obtained by direct registration of three-dimensional data between frames in the disparate sequences. These geometric stitches are then used in addition to or in place of other camera path relationships to form a single virtual stitch graph for the combined model, upon which an integrated global path optimization can be performed. | 12-12-2013 |
