Who we are?

We are the group of 3D Modelling and Virtual World from Finnish Geospatial Research Institute. You may find us here.

We are aiming for high automation in map updating, object detection and 3D model reconstruction; we are aiming for constructing detailed photorealistic 3D models; we are aiming for immersive virtual environment development.
