Procedure

  1. Go to Data Processing > Processed Data.

    processed_data_menu

  2. Select the Dataset(s) you want to download.

    select_the_datasets_to_add

  3. Click the Download button.

    download_datasets

  4. Choose an output file and, if applicable, a data format.

    quality report4

    Note: When multiple datasets are selected, quality reports are downloaded as individual files and it might take few minutes.

Output files

The following output files are available for download

  • Filtered point cloud: the filtered and smoothed point cloud.

  • Filtered point cloud in control points coordinate system: the filtered and smoothed point cloud in the coordinate system of the control points used during processing.

  • Panorama images (.zip): download panorama images.

  • Dataset archive (.nvd): an archive of the dataset, e.g. for backing up the data.

  • Control points log (.log):

    • Alignment log: the log file generated during the alignment stage of post-processing.

    • Optimization log: the log file generated during the optimization stage of post-processing.

    • Verification log: the log file generated during the verification stage of post-processing.

  • Surveyed control points (.csv): the file uploaded during configuring new processing task.

  • Raw point cloud (NavVis M6 only): the filtered but unsmoothed point cloud.

  • Raw point cloud in control points coordinate system (NavVis M6 only): the filtered but unsmoothed point cloud in the coordinate system of the control points used during processing.

  • Quality Report: View detailed information about the dataset.

Data formats

If you download a Point cloud file, you can also choose a data format. The following data formats are available:

  • .e57

  • .ply

Note: If you enabled the option Include panoramas in .e57 point cloud in the processing settings, the .e57 files contain unstructured point clouds and panorama images in a spherical representation. These files are compatible with the following third-party software:

  • Leica Cyclone 3DR Viewer

  • Cloud Compare

  • AVEVA

  • Prevu3D

  • PTC

Quality Report

  • Summary: Dataset capture and processed details including processing time, device serial and software version.

  • Processing settings: Dataset processing details including panorama settings, surveyed control points usage and coordinate system information.

  • Xray Maps: Floor plans that provide detailed insights into environments to visualize the structure and layout of buildings, including the distribution of rooms, corridors, and other spaces.

  • Quality Maps: The quality map illustrates the mapping quality by displaying the trajectory estimate, capture locations, and representing point cloud density through various shades of blue before and after processing.

  • Control Point Details:

    • Alignment residuals: Alignment residuals refer to the discrepancies between estimated and surveyed control point positions.

    • Optimization residuals: Optimization residuals denote the deviation in the trajectory of estimated vs. surveyed control point positions after all optimization steps inside SLAM have completed.
