Photometric Stereo with General, Unknown Lighting

A CCD camera is essentially a grid of photometers, simultaneously measuring and recording the photons coming from all the sources in the field of view. Because each CCD image records the photometry of multiple objects at once, various forms of photometric extraction can be performed on the recorded data; typically relative, absolute, and differential. All three will require the extraction of the raw image magnitude of the target object, and a known comparison object. The … WebPhotometry - Introduction In the field of optics, photometry is defined as the term that provides the measurement of light, as recognized by the eye of a human being.
