In this paper, a novel technique, called the photogeometric technique,is presented for surface reflectance extraction and surface recovery from animage sequence of a rotating object illuminated under a collinear lightsource (where the illuminant direction of the light source lies on or nearthe viewing direction of the camera). The rotation of the object is preciselycontrolled. The object surface is assumed to be smooth and uniform. Thetechnique first computes the 3D locations of some surface points which give singular brightness values and builds the surface reflectance function byextracting the brightness values of these surface points from the imagesequence. Then the technique uses the surface reflectance function and two images of the surface to recover surface depth and orientation simultaneously. The technique has been tested on real images of surfaces with differentreflectance properties and geometric structures. The experimental resultsand comprehensive analysis show that the proposed technique is efficient androbust.
