Abstract

As for any photogrammetric application, the accuracy of the derived object data is mostly dependent on the accuracy of the camera calibration. For many photogrammetric applications, use of a simple model for lens distortion in conjunction with co-linearity equations is sufficient. However, the combination of very close ranges and the large distortions typically associated with the lenses used on line scan cameras requires an extended lens model to account for variation of distortion within the object space. The fidelity of the calibration model becomes particularly important where stringent tolerances are set, for example construction experiments or surface measurement.
