to thirty level references have been surveyed with an automatic level Pentax AL320. Not having the x,y coordinates of the reference points may seem to be quite imprecise but the points we took were on near flat surfaces which are easy to locate with the help of a sketch or picture. Some of them have been taken with the rod up-side-down because it is easier to identify those being above the scanner than other on the ground which was irregular and may be hidden by plants. All of those levelled points were used for the absolute orientation of the model with the RMS of the being below 0.002m for the vertical adjustment. The 145 scans covering the most of the inner and outer surfaces of the church where registered simultaneously with the help of a dedicated application Polyworks by Innovmetric which has demonstrated to be pretty capable for such as complex task. (by the time this work was done, the aligning algo- Figure 8: The final polygonal model of the outside skin. Figure 9: Vaults model registered to exterior. rithm was not yet implemented in our own developed software UVACAD). More comprehensive data, where needed to record the temple’s interior. They provide a global model of the vaults and roof. The relationship between the outer model and the inner one was possible thanks to the care taken while scanning the main entrance of the church from the outside. Some pillars and walls were captured from the exterior scans allowing to register the two models together. A correct orientation and level allows the selection of a reference system given by a trihedral associated to ideal symmetric planes. The origin of this reference system has been placed at the intersection of the building axes at ground level. Thus it is possible to obtain three-parametric families of planes which are pair wise orthogonal between them.
