Effect of truncated overlapping projection data in a multi-pinhole ...
WebThe Spherical Gantry is a versatile four-axis motion system designed for optical scatter-ing measurement. It is sufficiently general to provide the motion required to measure any part of the scattering function, which makes it unnecessary to build new apparatus for each project; WebMar 29, 2024 · Directly capturing a general, near-planar reflectance sample can be performed with a spherical gantry, which exhaustively samples the combinations of all lighting and view directions (Dana:1999:BTF; Lawrence:2006:TREE). This results in thousands or even millions of photographs, making it prohibitively expensive both in time … emt scope of practice washington
Deep View Synthesis from Sparse Photometric Images
WebOct 19, 2015 · An archetypical example is the Stanford Spherical Gantry, the progenitor of various similar instruments. This gantry has a camera arm with two rotational degrees of freedom and a light source arm with one rotational degree of freedom, with the object to be measured placed on a central stage. A diagram of a spherical gantry can be found in Fig ... WebAug 1, 2024 · While relighting from sparse images has received significant attention, there has been relatively less progress on view synthesis from a sparse set of "photometric" images—images captured under controlled conditions, lit by a single directional source; we use a spherical gantry to position the camera on a sphere surrounding the object. In ... The Stanford Spherical Gantry is a room-sized goniometer, consisting of twocomputer-controlled arms that describe concentric shells around an objectplatform. A variety of illumination and sensing devices can be mounted on thearms. The clear working volume above the object platform is … See more The problem of measuring the angular dependence of reflection and scattering iswell studied in the applied physics community, where the devices are generallycalled scatterometers or gonioreflectometers. … See more We envisioned four uses for the gantry: 1. Digitizing 4D full-surround light fields under arbitrary illumination 2. Measuring 6D spatially varying BRDFs and BDTFs of 2D samples and 3D objects 3. Measuring 8D BSSRDFs, or … See more The design drawings for the Stanford Spherical Gantry are available (for free,we think) from Cyberware, if anybody would like them.
