Create and edit a reconstruction
You can generate raster and 3D products by creating a reconstruction and processing it in a workspace. A reconstruction can use multiple camera sessions and lidar 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, 3D mesh, and Gaussian splats products.
Create a reconstruction
To create a reconstruction, complete the following steps:
On the ribbon, click the Home tab, and click New Reconstruction
.Provide a name for the reconstruction in the Reconstruction Name text box.
Under Workspace, click Browse
. Browse to and choose the workspace where the reconstruction will be processed, and click OK.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 on the General page of the Options dialog box.
In the Sessions section, choose at least one camera session.
Reconstruction using a lidar session only is not supported.
Tip:
Previously aligned camera sessions are in their respective alignment.
The lidar sessions are not part of the aligned capture sessions.
Check a capture session to automatically check all the included camera sessions and the optional lidar session.
Click the Capture Scenario drop-down menu, and choose the scenario that best fits the camera sessions and lidar sessions used as input to the reconstruction.
Note:
The Aerial Nadir
option requires values for Forward Overlap and Sideward Overlap.In the Quality section, choose Ultra, High or Rapid.
The Ultra option results in the best quality. The High option results in faster processing with good quality. The Rapid option results in the fastest processing of DSM, True Ortho and Point Cloud products with reduced quality.
Note:
The Rapid option uses information generated during alignment and requires aligned capture sessions as input to the reconstruction. The Rapid option is not available for reconstructions with lidar sessions as input.
In the Products section, choose the products to reconstruct.
Note:
Each reconstruction scenario has default products.
The DSM Mesh product is only available for the Aerial Nadir
scenario.

Click Create.
Alternatively, click the Create drop-down arrow and choose one of 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.

Optional and advanced settings
You can specify further settings in the Optional and Advanced Settings sections.
Configure optional settings
To configure Optional settings, open the Reconstruction pane and expand the Optional section for the following options:
Check the Mesh Formats check boxes to generate additional mesh formats.
Note:
Mesh Formats can only be chosen when Mesh or DSM Mesh is selected as a product.
Click the Region of Interest drop-down menu and choose a region of interest.
Specify the Output raster pixel size for raster products.
Note:
The Output raster pixel size can only be set when True Ortho or DSM products are selected.
Specify the Tile Size value of the tiling scheme.
Under Tiling Origin, provide the coordinates for the raster and point cloud products in the X and Y text boxes.
Click the Coarse Water Body Geometries drop-down menu and choose a water body geometry.
Click the Precise Water Body Geometries drop-down menu and choose a water body geometry.
Configure advanced settings
To configure Advanced Settings, open the Reconstruction pane and expand the Advanced Settings section for the following options:
Click the Correction Geometries drop-down menu and choose a correction geometry.

Note:
Quality control geometries are not used to create reconstructions.
The Edit Packages parameter is only enabled when editing a reconstruction.

Check the Generate DSM Metainformation check box to produce additional raster files with metadata for the DSM.
Note:
Generate DSM Metainformation can only be set for the Aerial Nadir scenario and when DSM is selected as a product.
Choose the True Ortho bit depth.
The default is 8 Bit.
Note:
The True Ortho bit depth option can only be set to 16 Bit if the input imagery has a bit depth of 16-bit, the scenario is Aerial Nadir, and True Ortho is selected as a product.
Only unoptimized images can be used for reconstructions in 16-bit.
Warning:
Setting the True Ortho bit depth to 16 Bit will significantly increase the required storage and the runtime.
Tile size
You can define the tiling scheme for raster and point cloud products when creating the reconstruction. You can specify the output raster pixel size, tile size, and tiling origin settings. This means results can meet necessary specifications without additional postprocessing operations.
An important factor to consider when specifying manual tile size is that it can lead to lower performance or require more hardware resources to generate.
General recommendations for maximum tile sizes based on hardware resources are listed below.
|
Memory/RAM |
Recommended for nadir scenario |
Recommended for oblique scenario |
Recommended for drone scenario |
|---|---|---|---|
|
64 GB |
Maximum 2000 x output raster pixel size |
Maximum 4000 x output raster pixel size |
Maximum 2000 x output raster pixel size |
|
128 GB or more |
Maximum 5000 x output raster pixel size |
Maximum 4000 x output raster pixel size |
Maximum 2000 x output raster pixel size |
Note:
The tile size provided must be a multiple of the raster pixel size.
Reconstruction template
A reconstruction template is a .json file that stores all the parameters entered in the Reconstruction pane. You can export a template to save your settings and import it later to restore those values.
Export a reconstruction template
To export reconstruction settings to a new template file, complete the following steps:
In the Reconstruction pane, click Manage Reconstruction template
and click Export Template 
.Browse to the desired location and enter a name for the template.
Click Save.
The reconstruction template is saved to the specified location.
Tip:
To merge the current reconstruction settings into an existing alignment template, click Extend Template 
.
Import a reconstruction template
To import a reconstruction template, complete the following steps:
In the Reconstruction pane, click Manage Reconstruction template
and click Import Template 
.Browse to the template file, select it, and click OK.
The Reconstruction pane is populated with the values from the template.
Set a default reconstruction template
To set a default alignment template, complete the following steps:
Click the Project tab on the ribbon. In the list of side tabs, click Options.
The Options dialog box appears.
If necessary, click General.
Under Default templates, for Reconstruction, click Browse
.Select the application template and click OK.
Every time you use the Reconstruction pane, the values are automatically filled using the alignment template.
Edit reconstruction settings
To edit the reconstruction settings, complete the following steps:
In the Project Tree pane, select a reconstruction to edit.
On the Reconstruction tab, click Settings
.Edit the reconstruction settings as needed.
Changing some settings can cause the reconstruction to reset. This permanently deletes all of its data from disk.
Click Save.
On the Reset Reconstruction dialog box, click OK.
The reconstruction is updated.
