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 | Local coordinate system, maximum 400 million polygons |
| Textures | *.jpg or *.png | Resolution not more than 8192x8192 pixel, not more than 100 pieces |
| Kameraparameterdatei | All OPF Files | |
| original images | *.jpg or *.png |
- The model must be exported in WAVEFRONT OBJ format and must not exceed a size of 400 million polygons.
- The camera files must also be exported in OPF 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
Preparation for a Local Coordinate System:
1. After inserting the images, check the applications bottom left to see what is displayed (see Image).
2. If 'Local Coordinate System' is displayed, proceed with exporting the camera files in OPF format.
3. If something else is displayed, click on 'Tie Points' (see Image), 'Camera' and change the coordinate system to 'Local Coordinate System' in the pop-up window (see Image).
Preparation for a Georeferenced Coordinate System:
1. After inserting the images, check the applications bottom left to see what is displayed (see Image).
2. If a coordinate system with an EPSG code is displayed, proceed with exporting the camera files in OPF format.
3. If 'Local Coordinate System' is displayed, click on 'Tie Points' (see Image), 'Camera' and change the coordinate system used by for your images, using a EPSG code in the pop-up window (see Image).
Note: If you do not know the EPSG code of your images coordinate system, visit the website srs.twinsity.com and drag an image of the model into the window. You will then receive the EPSG code, which you can enter into PIX4Dmatic.
Export after Processing:
Export Camera Files in OPF Format:
Click on 'File', 'Export', 'Project as OPF' (see Image).
2. Export using the settings specified in the pop-up menu (see Image).
3. Specify a destination for saving. A folder named 'OPF' will be created. This entire folder must be uploaded later.
Export the 3D Model as OBJ:
1. Click on 'File', 'Export', 'Mesh' (see Image).
2. Export using the settings specified in the pop-up menu (see Image).
3. Specify a destination for saving. OBJ, texture, MTL, and XYZ files will be created. All these files must be uploaded later.
After Export:
The following files must be packed together in a single folder and uploaded (should look like in the image):
- OBJ file (model folder)
- MTL file (model folder)
- Texture file (model folder)
- XYZ file
- OPF folder
