Team: 2 land surveyors with experience in 3D scanning/ 1 land surveyor with experience in point cloud processing

Workflow (office and on-site):

  • Acquisition of site located in Bucharest
  • Establishing the positioning for the scanning stations and the resolution used according to the degree of detail required by the design theme
  • Connecting the previously positioned stations was carried out on the basis of the scanned common plans (the common plans are represented by floor, ceiling, partition walls). A total of 101 3D laser scanning stations were implemented.
