Patent number: 10861218Abstract: An exemplary volumetric reconstruction system accesses first and second color and depth data captured for a surface point on a surface of an object in a real-world capture space. The first color and depth data is captured by a first capture device positioned to have a first vantage point of the surface of the object, while the second color and depth data is captured for the surface point by a second capture device positioned to have a second vantage point of the surface of the object. Based on the first and second color and depth data, the volumetric reconstruction system determines a confidence field value for a voxel node corresponding to the surface point, and, based on that confidence field value, generates reconstructed color and depth data for a volumetric reconstruction of the surface of the object. Corresponding methods and systems are also disclosed.Type: GrantFiled: February 21, 2020Date of Patent: December 8, 2020Assignee: Verizon Patent and Licensing Inc.Inventor: Oliver S. Castaneda

Patent number: 10849679Abstract: The invention relates to a heat sink parameter determination apparatus for determining a parameter of a heat sink like a blood vessel within an object such as a person (3) by minimizing a deviation between a measured temperature distribution, which has preferentially been measured by ultrasound thermometry, and a modeled temperature distribution, wherein the modeled temperature distribution is modeled based on a provided heat source parameter like the location of an ablation needle (2) and the heat sink parameter to be determined by using a given thermal model. This determination of heat sink parameters, which may be geometric and/or flow parameters, considers the real temperature distribution and is thus based on real heat sink influences on the temperature distribution. This can lead to an improved determination of heat sink parameters and hence to a more accurate temperature distribution which may be determined based on the determined heat sink parameters.Type: GrantFiled: February 3, 2015Date of Patent: December 1, 2020Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Ajay Anand, Shriram Sethuraman, Sheng-Wen Huang, Junbo Li
