In the medium and long term, development of products in the area of photogrammetric 3D modeling—taking into account that the everyday use of 3D modeling based on photogrammetry usually fails due to two major weaknesses:
- rudimentary handling of camera poses;
- necessary filling of holes in 3D models.
As a solution to this, two self-developed methods are currently available:
- Own method for a monocular stereoscopy—in particular including smartphone specific boundary conditions: Convergent Monocular Stereoscopy.
- New method for interactive hole filling in 3D surface meshes: Interactive Filling of Holes in 3D Meshes using localized "Screened Poisson Surface Reconstruction".
A third method of estimating camera poses is in progress:
- Stereo Depths and Occlusion Boundaries based Estimation of Camera Poses.
Since the method mentioned in item 2. (see above) only allows holes to be filled after surface reconstruction, an alternative method is currently being developed that detects and fills holes in 3D point clouds before surface reconstruction has taken place.
From around 2019 onwards, TOF cameras (infrared 3D cameras) will increasingly be installed in smartphones, meaning that smartphone-based 3D modeling will have to be viewed in a different light—especially with regard to SfM (Structure from Motion) and MVS (Multi View Stereo).
