A must-see! 【Drone Work Examples】 Plane Surveying

Correct and analyze with high-precision position coordinates! It is easy to create necessary cross-sectional views from point cloud data.

In UAV plane surveying, the installation of control points is entirely done manually, accounting for about 35% of the total work time. Reducing this task as much as possible is key to increasing productivity. According to an announcement from the Ministry of Land, Infrastructure, Transport and Tourism, "If a technology for accurately grasping the self-position measurement of UAVs (RTK, PPK) is introduced, the installation of ground control points can be optional, and only accuracy verification at verification points is required." This allows us to omit the installation of control points when capturing images with our UAVs "Phantom 4 RTK" and "Matrice 210 RTK," which are capable of self-position measurement, thereby enhancing productivity. Additionally, we use PPK (Post-Processed Kinematic method using virtual reference points) to correct and analyze to high-precision position coordinates (within ±3 cm in all directions). By conducting drone surveys and generating point cloud data from continuous images with high-precision position coordinates using SfM, there is no need to measure the coordinates of control points and verification points with surveying equipment. This leads to a reduction in work time compared to conventional surveying, and it becomes easy to create necessary cross-sectional views from the point cloud data. *For more details, please refer to the PDF document or feel free to contact us.*
