Abstract

For highest accuracies it is necessary in close range photogrammetry to account for the variation of lens distortion within the photographic field. A theory to accomplish this is developed along with practical method for calibrating radial and decentering distortion of close-range cameras. This method, the analytical plumb line method, is applied in an experimental investigation leading to confirmation of the validity of the theoretical development accounting for variation of distortion with object distance.
