Three-Dimensional Photogrammetry for Laboratory Applications

摘要

The direct linear transformation (DLT) is a method that simplifies measurementsof the three-dimensional coordinates of a point target in the laboratory using photographic two-dimensional imagery. This report describes a procedure to implement the DLT equations and gives the Fortran code of computer programs for the DLT calibration of multicamera system and 3-D reconstruction of a single point from several images.
