Photometric calibration of zoom lens systems
WebAug 25, 1996 · This paper describes a calibration method of zoom lens systems to eliminate the photometric distortion due to vignetting. A novel camera model including the variable cone is proposed to account for the marginal intensity reduction observed in images. WebSep 1, 2006 · Zoom sequence calibration Full range zoom calibration can be done by building a mosaic and repeating the process described in Section 3.1 at multiple camera zoom levels. This would be slow since more images are needed as the camera zooms in and its effective field-of-view decreases [8].
