[Achievements] Image Diagnosis of Steep Slopes Using UAV-Mounted Lasers

We improved the efficiency of inspection work for slope failure prevention facilities using laser surveying mounted on UAVs!

The steep slope collapse prevention facility poses challenges in ensuring the safety of inspection workers, particularly in areas outside the site, such as the upper parts of slopes over 100 meters in height and covered with trees. By using "UAV laser surveying," we can obtain point clouds of the entire slope. After processing, we create "topographic images" such as contour lines, DSM, DEM, and CS 3D diagrams. This allows for the visualization of the three-dimensional shape of the steep slope collapse terrain beneath the trees, the location of the steep slope collapse prevention facilities, and the catchment topography that causes slope collapses, which could not be confirmed through aerial photographs. By utilizing the visualized images, we can conduct field surveys focused on abnormal points, thereby improving the efficiency and accuracy of the work. 【Data】 ■ Location: Shiojiri City ■ Client: Matsumoto Construction Office ■ Project Duration: 2020.09 to 2021.05 ■ Responsible Branch: Matsumoto ■ Design Items: Erosion control facility inspection, steep slope collapse prevention facility, 1 set ■ Overview: Conducted regular inspections as stipulated in the longevity plan for erosion control facilities. *For more details, please refer to the PDF document or feel free to contact us.
