Photorealistic 3D models

The resolution at which 3D data is collected means that it is possible to visually bring 3D models in life in a manner that extends beyond standard photographs. The tightly integrated photogrammetric and lidar capture systems used by the DEPHOS Group simultaneously collect 3D data in the same coordinate space, leading to the production of colorized point clouds. From here, a range of meshing techniques are applied before these surfaces are then edited for quality control by DEPHOS Group data visualization specialists to produce 3D models with photographic qualities.  

There is obvious application to heritage projects where there is value in creating as realistic record as possible of as-built conditions. Models created with 3D survey systems lead to accurate dimensioning that can be relied upon. These digital models can then provide the best source of reference information should restoration of the structure be required in the future. Photorealism enables easier communication of information to the general public and has led to photorealistic modelling techniques being used in the web-based e-learning systems developed by the DEPHOS Group team. Moving to applications that simulate the future, photorealistic 3D assessments are increasingly required to assess the visual impact of planned building work, especially in already densely built city centers.
