Abstract :
[en] Nowadays, mean 3D data aquisition techniques are photogrammetry and laserscanning. Their advantage is the huge amount of points that can be measured in a very short time on the field. Nevertheless, the post-processing associated to these techniques allowing to build a real 3D model from the clouds of points is very long. Therefore, we developed a geocodification ("field to finish") for the 3D data acquisition at a low and/or middle level of details. Despite each point is measured one by one with a total station, the user can gain a lot of time because of the almost-absence of post processing. This paper shows some of the developed techniques and tries to demonstrate the possible complementarity between geocodification, laserscanning and photogrammtry.
