Photogrammetry Measurement into Nuclear Areas: From As-Built 3D Modeling to Real-Time Assistance for Modifications

Abstract

Photogrammetry followed through the whole life cycle of a nuclear plant. For dismantling, it supplies an inventory of fixtures, a means of communication between operators, management and the safety authorities, and the basis for planning the operations themselves – two hundred pictures and two weeks of processing for one campaign. For modifications, it supports adding and replacing equipment, at roughly a thirtieth of a pixel on targets with the best camera, a tenth with a low-resolution camera and close to a whole pixel on natural features. The talk also covers construction work, ESIC-SN's technical developments, the IPROMES project and where real-time assistance was expected to go next.
