Valencia, Spain: Researchers at the Polytechnic University of Valencia (UPV), Spain, have developed a new geo-referencing system for generating 3D models with high accuracy and facilitate the work of geo-referencing of optical sensors or laser imaging.
According to a statement from the UPV, the portable multi-camera photogrammetric system enables low cost 3D modelling applications such as documentation of historical and artistic heritage, and geo-referencing of mining, archaeological sites or forest fires.
The inventory of road networks, urban or geological outcrops are other applications of the system developed by the Research Group on Photogrammetry and Laser Scanner (GIFLE) of the UPV.
According to José Luis Lerma, GIFLE researcher, the system expands the concept of geo-referencing of images to all types of applications and technologies through 3D, “expanding the possibilities of Google Maps with Street View, but much more cost competitive.”
“It solves problems of spatial orientation and allows a mixed geo sensors combining different forms of GNSS (GPS, GLONASS or Galileo) with an inertial navigation system (INS) and the traditional photogrammetric solution that requires a lot of support points (topographic)” adds José Luis Lerma.
It can also be used in physical settings for simulations metrics, both real and virtual, allowing calculation of 3D objects, create digital models, textures project captured by the cameras, develop continuous mosaic multi-band information and merge information from different métricoespectral sensors.
