La photogrammétrie par smartphone au service du récolement de réseau en fouille ouverte

Abstract : Since July 1st, 2012, the record drawing of networks is compulsory and these must be georeferenced according to the class A of precision. So, in the field of the public works, the land surveyor is called to come regularly on the construction site, meaning in every pose of network before the trench is closed. To answer at this issue, the implementation of a photogrammetric method for the record drawing of network was studied in this present report. Various tests realized on the construction site allowed to establish a method using the smartphone in excavation site. At the end of these tries, the precision has proved in the desired tolerances of the class A of precision. The method would consist in the fact that the works foreman makes video of networks. Having arranged targets before in edge of trench, they would be visible on these videos and then recognizable during processing on computer. Finally, the land surveyor would come at the end of the works to raise these targets to allow the georeferencing of the model.
