Abstract:

Some basic geometrical qualities of various photogrammetric plotting instruments were investigated. From grid-method tests of the interior orientation of different projectors, the basic geometrical quality of the reconstruction of bundles of rays was determined. Weigh variations were determined, and the statistical distribution of residual errors was tested after comprehensive practical measurements. Numerical procedures for the determination and adjustment of certain regular errors in projectors with mechanical projection were derived and applied to practice. Significance tests were applied. Through y-parallax tests, some relations between varying image resolutions and geometrical quality were investigated in a superwide-angle plotter. Similar tests were also applied to two other instruments with optical projection. Author
