Our research focuses on point cloud data processing and visualization, working with airborne LiDAR, grounded LiDAR, and LADAR sensor data. We focus on enhancing datasets through terrain reconstruction, filling terrain holes, and reconstructing buildings and water surfaces, as well as generating training datasets for object detection. Our work also includes point cloud segmentation and the development of advanced tools for data modeling and manipulation, particularly within Blender. On the rendering side, we explore techniques such as CNN-based image reconstruction, nearest neighbor interpolation, denoising, supersampling, Gaussian splatting, and NeRF adaptations. Additionally, we integrate data from multiple sources, including GIS and orthophoto data, through data fusion. We aim to implement our solutions in web-based implementations, enabling broader accessibility and application.
