An optimized data reduction technique in photogrammetry

Abstract

dc:description

The Direct Linear Transformation (DLT) method was first reported on in 1974 as an attractive alternative to existing photogrammetric reduction schemes for non-metric photography. While DLT resolved the problems of non-metric photography not having camera calibration information or fiducial marks for transformation of measured comparator coordinates to image coordinates, it was extremely limited in blunder detection capabilities and required an inordinately large number (six) of control points per photo for a solution.
