[Example] Establishment of control points in aerial photogrammetry

Introducing examples using the network-based RTK method!

We would like to introduce a case study by Fujiyama Co., Ltd. on the installation of reference points in aerial photogrammetry using network-based RTK. Aerial photogrammetry requires reference points for photo referencing, and the work area is extensive, typically involving measurements with 3 to 4 reference point accuracy based on public coordinates. In this case study, we utilized the network-based RTK method for the installation of 36 reference points over a work area of 25 km² while conducting bore-sighting and accuracy verification of the POS system used in aerial photogrammetry. The work area had good conditions for surveying, with clear visibility and good mobile phone reception in flat terrain. 【Benefits and Effects】 ■ Observations can be made with a single device ■ Short observation time without the need to consider line of sight ■ Reduction in the number of workers and shortening of the construction period ■ Work can be carried out with less than half the man-hours compared to conventional methods *For more details, please refer to the PDF document or feel free to contact us.
