Image-Based BRDF Measurement
نویسندگان
چکیده
We present a new image-based process for measuring surface reflectance rapidly, completely, and accurately. Requiring only a digital camera, a light source, and a convex curved test sample, our method can measure the BRDF with high resolution and accuracy over a very large domain of illumination and reflection directions. We have verified our measurements both by tests of internal consistency and by comparison against measurements made using a gonioreflectometer.

A fast and accurate image-based measuring system for isotropic reflection materials
We present a novel image-based BRDF (Bidirectional Reflectance Distribution Function) measurement system for materials that have isotropic reflectance properties. Our proposed system is fast due to simple set up and automated operations. It also provides a wide angular coverage and noise reduction capability so that it achieves accuracy that is needed for computer graphics applications. We test...
متن کاملImage-based Rendering of the AnisotropicBRDF ofWoven Fabrics
The reflectance of fabric surface is commonly represented by a 4D bidirectional reflectance distribution function (BRDF). To generate the BRDF from measured data by a gonioreflectometer with 2 degrees of freedom of the light source and 2 degrees of freedom of the observing direction, it requires an enormous amount of measurements. In this paper, we propose an efficient image-based method for re...
متن کاملSpectral BRDF-based determination of proper measurement geometries to characterize color shift of special effect coatings.
A reduced set of measurement geometries allows the spectral reflectance of special effect coatings to be predicted for any other geometry. A physical model based on flake-related parameters has been used to determine nonredundant measurement geometries for the complete description of the spectral bidirectional reflectance distribution function (BRDF). The analysis of experimental spectral BRDF ...

Overhead multiand hyperspectral imaging has enabled a variety of quantitative remote sensing techniques, such as the determination of the abundance and health of vegetation through the Normalized Difference Vegetation Index (NDVI). In addition, anomaly and target detection have been made possible by advanced matched filter algorithms. However, the derived surface reflectance from which all thes...
متن کاملBRDF/BTF Measurement Device
Capturing surface appearance is important for a large number of applications. Appearance of real world surfaces is dif cult to model as it varies with the direction of illumination as well as the direction from which it is viewed. Consequently, measurements of the BRDF (bidirectional reectance distribution function) have been important. In addition, many applications require measuring how the e...
