New Frontiers of Image-Based Surveying

The development of Nvidia RTX GPUs and neural networks, such as Neural Radiance Field (NeRF), has revolutionized 3D graphics. These technologies enhance realism and rendering efficiency. NeRF generates 3D views from 2D images, reducing computation times and replacing GAN networks. Nvidia’s Instant NeRF algorithm uses multi-resolution hash grid encoding to speed up rendering, allowing detailed scenes to be created from a few photos. Applications include the reconstruction of moving objects and the surveying of inaccessible artworks, opening new frontiers in spatial representation.
