Technical plan for establishing a precise flight plan to ensure accuracy of 3D numerical modeling of road slopes

The government is continuously carrying out a project to install measuring instruments for real-time monitoring on road slopes designated as disaster risk areas. In order to evaluate the risk of road slopes and install measuring instruments in areas with a relatively high risk of collapse, 3D modeling is performed using drones, etc., and is reflected when designing measuring instruments. Drones are used to monitor displacement after installation, but high-quality results are needed rather than filming quality during planning. In order to closely observe and quantify the detailed situation of the instrument and changes around the instrument, flight technology specialized for slopes is required. In general, horizontal automatic flight technology is mainly used to acquire photo information with overlap. However, due to the information utilization characteristics of photo pixels, it varies depending on the height of the slope, making it difficult to secure the same quality. To compensate for this, manual flight is essential. In this study, we aim to present precision flight planning technology for economical and high-quality data acquisition through the process of establishing precision flight plans for about 50 slopes.
