ABSTRACT Architectural documentation is carried out mostly with (analogue or digital) non-metric cameras or video-cameras. Unknown internal geometry is a main problem in this context, particularly for wide-angle lenses with their considerable amount of distortion. Self-calibrating bundle adjustment or 3D test-field calibration may provide straightforward answers to this problem, yet on occasions such steps can prove too complicated or costly for ordinary users. Hence, this paper discusses the… CONTINUE READING
