NavVis

Prevu3D supports the following scanners from NavVis:

  • NavVis VLX (preferred)

  • NavVis M6


Data Collection

In order to achieve the highest quality results, the following is required:

Quality

Requirement

High overlap

Capturing areas with high overlap between passes to ensure there is little to no occlusion

Many images

Capture as many images as possible. Ideally panoramic images should be collected every 3 meters

Loop closures

Improves accuracy and error correction

Control points

For large scans this is recommended to reduce drift

Data processing

Note

NavVis offers both a local Linux processing option and a cloud processing option.

NavVis IVION Processing Settings

Select the following processing settings:


NavVis IVION Crop and Download

NEW! It is now possible to use the Crop and Download option in NavVis’ IVION software to download e57 files with panoramas. This feature allows NavVis point cloud data that was captured without control points to be aligned in IVION and exported in a compatible format for Prevu3D meshing. You can find more information on this feature in this documentation by Navvis.

Sitemaker Processing Settings (Linux)

Select the following processing settings:

Setting

Point Cloud Resolution: 5mm

Point Cloud Format: ply

Colorize point cloud: True

Generate panoramic images: True

If you are using Navvis Sitemaker to process your Navvis scans, you can retrieve the .nvd files from the generated datasets_web folder, and import these into IVION. From here, you can follow the usual workflow with the crop and download feature to export e57 files with panorama images.
