Purpose
Conducting visual inspections of slopes and steep inclines is time-consuming and labor-intensive. In addition, the existing document-based inspection data management system made it difficult to utilize inspection data. To improve this, KRRI aims to use drones to create 3D images of slopes and steep inclines, to analyze their condition, and to identify any sings of abnormalities.
Drone-based 3D Image Generation
Drone-based 3D Image Generation
• Collecting on-site image with drones
• Generating 3D images by overlapping drone-captured images
• Accessible even on steep slopes
Damage Locations Display
Damage Locations Display
• Displaying the locations of damaged areas on slopes and retaining walls
• Building a database of surface damage
Integrated management of regular inspections for slopes
Integrated management of regular inspections for slopes
• Tabulating slope inspection information
• Generating a risk-level map based on GIS
• Managing inspection report history
Expected Benefits
Labor Cost Reduction – Fewer personnel needed
Reduced Inspection Time – 3× faster
Efficient and Systemized Management of Slopes Inspection History
Remote Detection for Condition Analysis and Abnormality Signs in Slopes and Steep Inclines
