Abstract

Comparative tests of analytical and digital analysis systems were conducted. The experiment took the form of a photogrammetrical survey of a tower from the Roman peri od near Rome. To measure the x, y and z coordinates on an identica! regular grid both a DIGICART analytical stereoplotter and the STEREOVIEW 300 digital system were used. Tue STEREOVIEW 300 was produced by Nikon S.p.A. in collaboration with Dr L. Menci. Tue analytical system was used to semi-automatically plot a DTM with a regular 30 by 30 cm grid on each facade. Tue same operation was then repeated for each facade using the digital system in the two prescribed modes: semi­automatic (manual) and automatic. The data obtained in this way were used to compare a series of points. Their quality was also analysed on the basis of their position on the general architectonic structure (points that could be clearly identified, gaps, areas whose architectural features could not be clearly identified, etc.). Vertical and horizontal pro.files of the tower were also plotted in a single reference system in order to establish the spatial dimensions ofthe 3D model.
