Together, the companies: scan 3D, Metrotech and CDSC, carried out a project that aimed to test the combination of three technologies for spatial data acquisition: optical scanning, laser scanning and photogrammetry using a drone. To test, Kashubski Square in Gdynia was selected, which is characterized by a large space. Optical scanning worked perfectly when obtaining very accurate measurements of 0.1mm, characterized by a high density of 12 points / mm2. Laser scanning provided the necessary spatial architectural information, while the drone acquired geometry from the roofs of buildings. The effects of the project can be seen below.
