Create and edit a reconstruction

You can generate raster and 3D products by creating a reconstruction and processing it in a workspace. A reconstruction uses camera sessions as input as well as region of interest, water body, and correction geometries. Processing a reconstruction can generate digital surface model (DSM), True Ortho, DSM mesh, point cloud, and 3D mesh products.

Create a reconstruction

To create a reconstruction, complete the following steps:

1. On the Home tab, click New Reconstruction .
2. Type a name for the reconstruction in the Reconstruction Name text box.
3. From the Capture Scenario drop-down menu, choose the scenario that best fits the camera sessions used as input to the reconstruction.

   Note:

   The Aerial Nadir scenario requires values for Forward Overlap and Sideward Overlap.

   The Aerial Oblique scenario only generates point clouds and 3D meshes.

4. In the Camera Session section, choose at least one camera session.

   Tip:

   • Previously aligned camera sessions are in their respective alignment.
   • Check a capture session to automatically check all the camera sessions in it.

5. In the Products section, choose the products to reconstruct.

   Note:

   Each reconstruction scenario has default products.

   • Raster products—Specify a custom output raster pixel size.
   • Mesh products—Specify output formats.

6. Under Workspace, click Browse and choose the workspace where the reconstruction will be processed.

   You can either specify a path to an existing workspace or choose an empty folder. Reality Studio will automatically create the required folder structure. If you plan to contribute to this reconstruction from other machines, ensure that the workspace as well as all input data is available from the network.

   Tip:

   A default workspace can be defined in the General section of the Options dialog box.

7. Expand the Optional section, if necessary, and do the following:
   1. Choose Ultra or High for the quality.

      The Ultra option results in the best quality; the High option results in faster processing.

   2. Choose Region of Interest, Water Body Geometries, and Correction Geometries values from the drop-down menus.
   3. Under Raster Sampling Origin, provide the coordinates for the raster products in the X and Y boxes.
8. Click Create.

   Alternatively, click the Create drop-down arrow to find the following options:

   • Create and Submit—Create the reconstruction and add it to the workspace.
   • Create, Submit and Start Contribution—Create the reconstruction, add it to the workspace, and start contributing.

The reconstruction is created and appears in the Project Tree pane.

Edit reconstruction settings

To edit the reconstruction settings, complete the following steps:

1. In the Project Tree pane, choose the reconstruction with the settings you want to edit.
2. On the Reconstruction tab, click Settings .
3. Edit the reconstruction settings as needed.

   Changing some settings can cause the reconstruction to reset. This permanently deletes all of its data from disk.

4. Click Save.
5. On the warning dialog box that appears, click OK.

The reconstruction is updated.
