📋 Changes

• More complete sensor database and better matching as well as explicit status for lens initialization
• Add support for rig of cameras. This enables to add more contraints if you make acquisition with multiple synchronized devices.
• Support for reconstruction with projected light patterns and texturing with another images set.
• Better estimation of the space to reconstruct to limit the reconstruction zone. This avoid to reconstruct low quality and useless areas around the main object/environment.
• New option to directly mesh the SfM results. This provides a quick solution to get a draft mesh (without cuda requirement).
• Reduce IO and intermediate files in MVS part of the pipeline.
