Improve reconstruction results

Dense Matching reconstruction techniques can lead to suboptimal results when used on low-textured, highly reflective challenging surfaces. This is a common scenario for data acquired over cities with buildings whose facades are made of glass.

After processing of a reconstruction has finished, you can add or change the geometry files used as input and apply the changes to the reconstruction. The changes are evaluated in Reality Studio and processing steps that need to be repeated are determined so the changes are incorporated into the results of the reconstruction.

Improve reconstruction results using geometries

To use geometries to improve reconstruction results, complete the following steps:

In the Project Tree pane, choose the reconstruction you want to apply changes to.
On the Reconstruction tab, click Edit Geometries . Select the geometry to edit.

Note:

Alternatively, you can create a new geometry on the Home tab.
Use the editing tools on the Edit tab to modify the features.
Tip:
- Press the C key to temporarily enable navigation mode.
- Press Shift to temporarily disable snapping sketch assistance.
On the editing toolbar, click Finish .

Tip:

Alternatively, you can press the F2 key to finish the sketch.
On the Edit tab, in the Manage Edits group, click Save .

Changes to the input data are detected, and buttons to apply the changes appear in elements where these geometries have been used.
In the Project Tree pane, click Apply changes on the reconstruction where you want to apply the changes.
On the warning message, click Apply Changes.

The reconstruction is updated and automatically resubmitted to the workspace.

New tasks are added to the original reconstruction job, which is processed according to its position in the workspace queue. Once processing has completed, the updated results can be visualized in Reality Studio.

Improve reconstruction results using an external application

You can improve reconstruction mesh results using an external application. On the mesh results, you can mark positions where improvements are needed using a quality control geometry. You can then create edit packages based on the respective quality control geometry. Edit packages include all information required to edit the surface geometry of the mesh in external applications. After updating the edit packages, you can re-introduce them to the reconstruction and apply the modifications. This workflow can be repeated multiple times until the desired result has been achieved.

Start by creating the quality control geometry. Inspect the mesh results and identify the regions that need improvement. In the respective quality control geometry layer, digitize polygons around these regions.
