1. Important – be sure to read this BEFORE you process your model
Make sure that all the required files are included in the upload:
|
Files |
Format | Other specifications |
| OBJ and MTL Files | Wavefront OBJ | |
| Textures | *.jpg or *.png | Resolution not more than 8192x8192 pixel, not more than 100 pieces |
| Kameraparameterdatei | Block Exchange XML | |
| original images | *.jpg or *.png |
- The camera file must be exported in Block Exchange XML format.
- The textures must always have a power of two as the number of pixels. Here, the highest resolution of a texture may be 8192x8192 pixels. The textures must be in *.jpg or *.png format. The number of textures must not exceed 100.
- Check your camera file (XML) again before uploading. Make sure that all images you want to see in TWINPSECT are present in this camera file. (During the upload your data will be validated again. Again, check the number of images in the validation overview).
- Please read the step by step instructions carefully. The red marked parts are very important and decide about the successful upload of your project.
2. Export your TWINSPECT® model
Align Photos
Once you have inserted the photos, press 'Workflow' in the menu and then 'Align Photos'.
Here you make the following settings:
Important:
If you move the point cloud again, you must repeat this step and then create the mesh.
If you move the whole mesh, you have to start again at the step "Align photos".
Build Mesh
Then go to "Build Mesh" in the "Workflow" menu and make the following settings:
Build Texture
After the mesh is created, you create the textures as follows under "Workflow" and then "Build Textures":
Important:
The texture size and number must be set differently for each model.
The larger the model, the more textures must be created.
The texture size must be set to 4k or 8k.
Export model local
Export the generated model into a 3D mesh in the OBJ wavefront format. See below for the format options. By this, an OBJ file of the model with the corresponding textures will be generated.
Note: Please make sure to choose the local coordinate system, and to choose the same coordinate system for both the model and cameras export.
Export model georeferenced (EPSG)
Export the generated model into a 3D mesh in the OBJ wavefront format. See below for the format options. By this, an OBJ file of the model with the corresponding textures will be generated.
Note: Please make sure to choose the correct coordinate system, and to choose the same coordinate system for both the model and cameras export.
If you are unsure which EPSG code your project has, please upload an image to https://srs.twinsity.com, copy the EPSG code and paste it into the “Coordinate System” field (unfold and press more).
It is also important to click on the calculator icon after selecting the SRS system so that the shift is created.
Export Cameras local
After exporting the model into the OBJ format, please export the cameras into the blocks exchange format as an XML file. For this, please click on “File” and ”Export Cameras…” (see screenshot below).
Save Dialog: Then, the save dialog will show up. Please choose a filename and select the “Blocks Exchange (*.xml)” format and click on “Save”.
Export Cameras Dialog Finally, the following dialog will show up.
Note: Please make sure to have deselected the red highlighted check boxes for the tie points and control points. Further, please make sure to have selected the local coordinate system as you chosen when exporting the 3D model.
When clicking on “OK“, the corresponding XML file will be generated that can be used to import the original inspection photos into TWINSPECT.

Important:
Make sure that all the required files are included in the upload:
- OBJ files
- MTL files
- textures (must not be larger than 16k. However, 8k is optimal for our program)
- camera file
- original images (*.jpg or *.png format)
3. Create your Twinsity Account and login
To create an account, please visit the TWINSPECT Dashboard:
On the start page you can log in with an existing account or register with a new one using the sign in and registration function. When the "Sign In" button is clicked, the registration window opens.
In the login window you can log in with an already created account and the corresponding password. With the checkbox "Keep me signed in" the login will remain after leaving the application, unless they have logged out.
To register a new account, click "Create an Account" and follow the following steps.
4. Upload your TWINSPECT® model
To upload the project to TWINSPECT®, press the "Create" button in our dashboard.
Now there are 5 steps to upload your project:
- Enter the name of your project, the asset type and choose “Agisoft Metashape” reconsturction software.
- Under "Select Source Folder", select the folder containing all project data files. Depending on the browser, select "View files" to display the images. Important: Our upload only works with Google Chrome or Microsoft Edge internet browsers.
- We validate your data before you can upload the data to avoid any problems. If there are any errors in your data, they will be displayed here.
- Your project will be uploaded.
- Your project is uploaded.
When your project is uploaded, you will see it under the "Project Draft" item in our dashboard.
Once the project is finished by us and accessible to you, the model will be displayed under the "Projects" item.
