    摘要： An interactive, autostereoscopic system for displaying an object in 3D includes a mirror configured to spin around a vertical axis when actuated by a motor, a high speed video projector, and a processing system including a graphics card interfaced to the video projector. An anisotropic reflector is bonded onto an inclined surface of the mirror. The video projector projects video signals of the object from the projector onto the inclined surface of the mirror while the mirror is spinning, so that light rays representing the video signals are redirected toward a field of view of a 360 degree range. The processing system renders the redirected light rays so as to interactively generate a horizontal-parallax 3D display of the object. Vertical parallax can be included in the display by adjusting vertically the displayed views of the object, in response to tracking of viewer motion by a tracking system.

    摘要： An apparatus for generating a surface normal map of an object may include a plurality of light sources having intensities that are controllable so as to generate one or more gradient illumination patterns. The light sources are configured and arranged to illuminate the surface of the object with the gradient illumination patterns. A camera may receive light reflected from the illuminated surface of the object, and generate data representative of the reflected light. A processing system may process the data so as to estimate the surface normal map of the surface of the object. A specular normal map and a diffuse normal map of the surface of the object may be generated separately, by placing polarizers on the light sources and in front of the camera so as to illuminate the surface of the object with polarized spherical gradient illumination patterns.

    摘要： An illumination reproduction apparatus and process for illuminating a subject with the illumination at a location in a scene when the subject is not in the scene. Scene illumination data is generated that specifies the illumination at the location in the scene from a plurality of spatial directions. The subject is then illuminated with the illumination at the location in the scene by driving a plurality of light sources surrounding the subject with the scene illumination data.

    摘要： A reflectometry apparatus and method is presented that allow the diffuse and specular reflectance parameters of an object to be independently and reliably measured, and that allow the variations in surface normal and surface height to be estimated. An extended light source having an elongated configuration, for example a linear cylindrical light source such as a neon tube, is moved across the surface of an object while a digital camera detects the reflected light to acquire a series of images of the object surface. A reflectance trace table is synthesized for a range of model parameters using a virtualized rendition of the linear light source. For each pixel, the observed reflectances are compared to the synthesized reflectance trace table, to determine the reflectance parameters that most closely match the observed data.

    摘要： An apparatus to measure surface orientation maps of an object may include a light source that is configured to illuminate the object with a controllable field of illumination. One or more cameras may be configured to capture at least one image of the object. A processor may be configured to process the image(s) to extract the reflectance properties of the object including an albedo, a reflection vector, a roughness, and/or anisotropy parameters of a specular reflectance lobe associated with the object. The controllable field of illumination may include limited-order Spherical Harmonics (SH) and Fourier Series (FS) illumination patterns with substantially similar polarization. The SH and FS illumination patterns are used with different light sources.
