An ancillary window (fig. 9) shows some image important parameters such as image size (lines and rows), frame
number, selected pixel (and its image position) and geometric and radiometric characteristics of the above pixel (range,
azimuth and polar angle, intensity). It is also possible to reference the inner system of the original image, associating to
single cells, 3D previously surveyed coordinates; the software will perform a plane transformation in order to rectify the
image.

2 FIELD TEST
2.1 Otto Wagner's Karlsplatz underground station
In 1990 a small test object had been selected, photographed, measured and documented, in order to get a well-checked
materials to train students and photogrammetrists as well as to evaluate internationally the results of the analytic
photogrammetric amount of control information. The test object was Otto Wagner’s Stadtbahn Station buildings on the
Karlsplatz in Vienna (fig. 10), a masterpiece of Art Nouveau, built in 1898-1899.

2.2 Performed surveys and measurements
This test field planned different acquisitions in order to reconstruct a 3D model of the underground station, leaving to
future analysis a metric test of the image acquired by the laser-scanner LMS-Z210. In fig. 11 is shown a sketch of the
different taking positions useful for 3D reconstruction.
In the following figures are shown all the different 4 takings; the images are range measurements where pixels varying
from orange to green represent closer to far points.
