About the Event
However, HSI data is typically stored as raster images, requiring resampling to fit a predefined grid. This introduces spatial distortion and storage overhead, often increasing the data volume by 10-20 times compared to the raw data during the time-consuming post-processing that is required. These challenges have limited the widespread use of HSI technology.
In the Horizon Europe M4Mining project we have developed a new UAV-based system that addresses these issues by processing hyperspectral data entirely onboard, in real time. This includes LiDAR-based 3D surface reconstruction, hyperspectral rectification, atmospheric correction (radiance to reflectance), mineral classification, and live streaming to a ground station for visualization in 3D during flight.
Our presentation will give a brief overview of the project and its main results, including a demonstration of the visualization using data from one of the open-pit mines that was used for testing and data collection during the project. In M4Mining, the system was built for mineral mapping in open-pit mines, but it is equally suited for vegetation monitoring, land-use assessment, and other environmental applications.
