Surface Reflectance Recovery under Point Light Illumination
نویسندگان
چکیده
In this paper, a novel algorithm for colour recovery is presented. It assumes that the 3-D geometry of the scene is known. The spectral power distribution of a point illumination source, and the response function of the sensor are calibrated jointly. This algorithm has been used for the colour recovery part of an integrated system, developed in our laboratory, for environmental modelling. The geometry of the scene is recovered using a laser stripe range-nder and this information is exploited by the colour recovery algorithm. A point light source, attached to the whole system, has been used for the illumination of the scene, in order to connne undesirable side-eeects of the ambient light. The joint spectral power distribution of this point light source and the response function of the camera are obtained with oo-line calibration.

Surface Reflectance Classifying under Natural Illumination
Though a point light source is more suitable to measure the BRDF of the surface, the natural illuminations in the real-world are not point light source and very complex. Fortunately, the complex natural illuminations exhibit some statistical regularity [3]. These statistical properties of the natural illuminations lead to predictable image statistics for a surface with given reflectance propert...
متن کاملReflectance and Shape Estimation with a Light Field Camera under Natural Illumination
Reflectance and shape are two important components in visually perceiving the real world. Inferring the reflectance and shape of an object through cameras is a fundamental research topic in the field of computer vision. While three-dimensional shape recovery is pervasive with varieties of approaches and practical applications, reflectance recovery has only emerged recently. Reflectance recovery...
متن کاملHow do Humans Determine Reflectance Properties under Unknown Illumination?
Under normal viewing conditions, humans find it easy to distinguish between objects made out of different materials such as plastic, metal, or paper. Untextured materials such as these have different surface reflectance properties, including lightness and gloss. With single isolated images and unknown illumination conditions, the task of estimating surface reflectance is highly underconstrained...

A new photometric method is proposed fo r determining the 3-D shape of t he object from multiple shading Images under the point light source illumination. When the surface is t he perfect diffuser with the uniform reflectance, an algorithm fo r the determination of 3-D shape with positions is developed by using the method of least squares and basing on the principle of the monocular vision and ...
متن کاملDetermining Reflectance and Light Position from a Single Image Without Distant Illumination Assumption
Several techniques have been developed for recovering reflectance properties of real surfaces under unknown illumination conditions. However, in most cases, those techniques assume that the light sources are located at inifinity, which cannot be applied to, for example, photometric modeling of indoor environments. In this paper, we propose two methods to estimate the surface reflectance propert...
