Processing the Scans

NavVis IVION

NavVis IVION is a cloud-based digital twin platform that allows users to present curated 3D-scanned sites with metadata like points of interest, waypointing and room information.

For most purposes, IVION will only be used for processing point cloud data for your further use cases in CAD or rendering. If you wish to use IVION for its presentation capabilities; check out this demo to see if suitable for your use-case; for setup, refer to the NavVis Knowledge Base or with NavVis Academy (free, sign-up with your own credentials).

Processing Workflow

  1. Remove the SSD from the socket located below the screen

  2. Use the provided USB cables to connect the SSD with a computer

LogoNavVis IVION

  1. Logon to NavVis IVION, the scanner's cloud processing companion. and navigate to the upload data page NExT Lab will provide you with credentials and details.

  2. You should automatically be in your dedicated cloud instance.

  3. Press Data Processing

  1. In file explorer, access the SSD > Data > datasets_rec

  2. Drag and drop the entire folder with the corresponding date and time of your scan into the 'upload recorded data' box

  1. Once uploaded, navigate to processing tasks on the left

  2. Click 'create a new processing task" and select your uploaded scan

  1. Configure settings depending on the nature of your scan and click start processing

  1. You will need to make the following changes to the point-cloud configuration

  • Point cloud resolution to 5mm: This is the highest quality possible. Always do 5mm and downsample afterwards if a lower resolution is required.

  • The high confidence setting has a range of 10m, and will be a smaller, but more complete scan.

  • The standard setting has a range of 30m and is good for interior or built up spaces.

  • The outdoor setting has a range of 50m. The point cloud density may be sparce on the edges for this reason, however, this setting is good for larger spaces.

  1. The scan will now be sent to the NavVis server for processing. This may take several hours.

  2. Once the processing status has changed to 'complete' navigate to processed data on the left.

  3. Here you can select and downolad your preferred files.

Next Steps

VLX point cloud outputs, as SLAM datasets, look different to stationary terrestrial scanning outputs - they tend to be noisier.

Meshing

You will find that you cannot run the recommended type of algorithms. Meshing them is harder as they lack a cloud structure that guarantees successful meshing.

Combining Datasets

Use point-to-point techniques to combine clouds together.
