Coordinate System Preservation with XMPs / Full-body Scans

This tutorial shows how to preserve a coordinate system while processing many datasets with reuse of a fixed-camera setup before a computation of camera parameters.

In the tutorial, a workflow with XMP metadata is used, which is suitable for processing of datasets obtained using a completely fixed-camera setup, i.e. fixed-cameras' position, orientation, focal length and everything else. 

NOTE: When using bending camera setup (cameras can move slightly), use XMPs exported as Draft.

• Creating a model step by step: add images, align the images, set ground control points, export XMP metadata, set and export a reconstruction region, create a model, simplify the model, replace the source images, texture the model, export the model.

• Creating a model using the XMP workflow: add images with XMP metadata, align the images, import a reconstruction region, create a model, simplify the model, replace the source images, texture the model, export the model.

•  Model comparison: a comparison of the reconstructed model with the one computed using the XMP workflow. 

• Command-line processing of 4 datasets using the XMP workflow: an illustration of command-line processing of many datasets being reused before a computation of camera parameters.
