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.
