RealityCapture allows automatic registration, filtration, coloring, texturing and meshing of laser scans. You are not limited by a number of laser scans and size of your project, even if the amount of data reaches terabytes.
You have already imported a laser scan to the project. Congratulations! You can skip the import step of this tutorial and create a 3D model from it or press ctrl+N to create a new scene and import the laser scan again.
RC supports PTX, E57, and ZFS/ZFPRJ laser-scanning file formats. Importing converts laser scans into an internal format with the .lsp file extension. Once laser scans are converted to .lsp files, you can work only with .lsp files as with images. There is no need to import laser scans again. You would only need to re-import laser scans if you wanted to change the import options.
Exact Imported poses will be preserved; in this case the imported model defines the scene coordinate system.
Draft Scanning stations have been registered but the registration needs to be fine-tuned.
Unregistered When the stations have not been registered, the registration engine will calculate poses of all scans.
Geo-referenced Set this option to Yes when your laser scans are geo-referenced and you want this type of data to be
included in your project. When set to Yes, you will also need to specify the coordinate system.
Features source Select whether to use a color or a laser intensity channel for registering photos to laser scans. Color is the default value. For Z+F scans use Color if there are corresponding .jpg files next to the source files.
Noise profile defines how the point cloud precision changes with the growing distance from the scanner station and laser intensity value. You can select Noise free profile, ScanStationP20 or define your own profile based on the laser scanner technical documentation. To add a new profile, edit the noiseprofiles.xml file. You can find it in the application executables folder.
Output path Specify a target folder for .lsp files.
When importing Z+F laser scan formats, you can select all .zfs files or you can select the .zfprj project. If the scans are arranged into a file chain, you only need to select one file from the chain and all other files will be imported as well. Please note, laser scans from Z+F Profiler scanner or other scanners in profiler mode are not supported.
RealityCapture can import .zfprj mosaic images and use them as feature source during the alignment process. This might help to register the unregistered scans or to automatically find the same features when merging laser scans with images. By default, this feature is enabled (set to "Yes"). You can find it in the Prefer images as feature source.as
To import .zfprj (Z+F project) with mosaic images:
The laser-scan import process automatically adds all imported laser scans (.lsp files) into the opened project. You do not need to add them again.
Next time you want to work with the same laser data, you do not need to import them again, simply add the respective .lsp files into your project.
To continue, add one or more laser scans into the project.
You can download and unpack a test dataset from our webpage - click to download. Import .ptx laser scan files located in the laser scan folder.
