Abstract
Abstract - This paper presents an approach for solving the geometric image deformation problem due to lens distortion, using B-Spline surfaces. The calibration method is described and experimental results are presented for a close range photogrammetry setup with an "off-the-shelf' CCD video camera and a 3D calibration frame. Active light sources, optical fibers, were used as calibration points. The design of the calibration frame was a result of experimenting with different light emitting diodes, background lighting, and optical fibers.
