Export your project with RealityCapture for TwinSpect

  • Updated

This is a quick workflow guide for setting up TwinSpect for inspection projects that were reconstructed by RealityCapture software.

How to setup TwinSpect for RealityCapture projects

Step 1: Export 3D reality mesh from RealityCapture

At first, the produced 3D model needs to be exported from RealityCapture. For this, please go to the Reconstruction tab in RC and click on Model in the Export section (highlighted in green).

This will open the following dialog. Here you can specify the filename of the mesh model. Please make sure to choose the Wavefront obj (*.obj) option as the file type. To change the file type, please open the drop-down menu like shown below.

Afterwards, the following option dialog will show up. Please use these shown options and parameters for exporting your 3D mesh model into the Wavefront obj format.

Now, when clicking on OK the 3D mesh model is exported alongside the corresponding texture files. In the next step, the camera alignment file (i.e., the registration) needs to be exported.

Step 2: Export camera alignment file from RealityCapture

In the next step, the camera alignment file (i.e., the registration of RC) needs to be exported. For this, please go to the Alignment tab in RC and click on Registration in the Export section (highlighted in green).

This will open the following dialog for choosing the filename of the exported alignment file. Please make sure to select Internal/External camera parameters as the file type. To change the file type, open the drop-down menu like shown below.RC6.jpg

Afterwards, the following export options dialog will show up. Please use the shown options and parameters to export the registration into the CSV file.

Notes on the inspection images

You can add as many original images to your TwinSpect project as you  like. It is not necessary to import all the original images used to create the model. So, you can just skip the alignment images and import the inspection images only.

There are two ways you can choose a subset of your original images.

  1. Define an image selection in RC before exporting the camera alignment CSV file.
  2. Choose an image folder containing only a subset of your original images when specifying the root folder of the images to be imported into TwinSpect.
