Processing Data in NavVis Cloud

With the Cloud Processing Add-On you can post-process your datasets in a cloud-based environment within NavVis IVION.

Prerequisites

  • A NavVis Cloud account
  • Data scanned with NavVis M6 or NavVis VLX with a valid cloud processing license. Contact your Technical Account Manager or NavVis Technical Support for details.
  • Administrator rights to a NavVis IVION instance or membership in a NavVis IVION user group with the Data Manager role

Uploading Data

Follow these steps to upload data for processing:
  1. Go to Site Setup > Upload Unprocessed Data.
  2. Upload your data. You have two options to do that:
    • Click Upload Data and choose the file(s) or folder(s) you want to upload.
    • Drag and drop the file(s) or folder(s) you want to upload.

Once the upload has started, your datasets will be listed on the Upload Unprocessed Data page with the following information:

  • Name
  • Status
  • Date and time the dataset was recorded
  • Number of panorama images included in the dataset
  • Size of scanned area

Processing Data

You can create a processing task while your data is still uploading. Once the upload is complete, the data will be processed.

Follow these steps to create a processing task:

  1. Go to Site Setup > Processing Tasks.
  2. Click Create a new processing task.
  3. Enter a name for the processing task or continue with the assigned default name.
  4. Select the dataset(s) you want to process.
  5. You can crop datasets before processing. To do that:
    1. Click the three dots next to the dataset you want to crop.
    2. Click Define processing time frame.
    3. In the window that opens use the slider to choose the part of the dataset you want to process.
    4. Click Define time frame.
  6. Click Next.
  7. Choose the desired point cloud and panorama settings.
  8. Optionally, upload measured control points in .txt or .csv format. To do that:
    1. Click Upload or drop a control points file (.csv, .txt) here to upload a file or drag and drop a file.
    2. In the dialog that opens, select Local reference system if your control points file is in a local coordinate system.
    3. Select Spatial reference system if your control points file is in a global coordinate system. Start typing a name and select the desired spatial reference system from the options that appear.
    4. Click Upload file.
    The control points file will be validated. If there are problems with your control points file this will be indicated and you will need to resolve the problem to ensure the successful processing of your data.
  9. Optionally, add up to five email addresses to receive updates on the completion or failure of your processing task.
  10. Click Start Processing.

Once you have created a processing task, it will be listed on the Processing Task page with the following information:

  • Name
  • Starting date
  • Number of datasets included in the processing task
  • Number of datasets that have been successfully processed
  • Number of datasets for which processing has failed
  • Progress of the processing task

You can expand a processing task to see the following information:

  • The datasets included in a processing task
  • The settings chosen for a processing task

Point Cloud Settings

The following point cloud settings are available for data captured with NavVis M6 and NavVis VLX:

  • Point Cloud Resolution
  • Point Cloud Color

The following point cloud settings are only available for data captured with NavVis M6:

  • Sharp Edges: Details and edges in the scanned area will be reconstructed with a low amount of smoothing, but the point cloud may exhibit some noise.

  • Balanced: The point cloud will be reconstructed with a balance between smooth surfaces and sharp edges.

  • Smooth Surfaces: Surfaces will appear smooth and with a low amount of noise, but edges will appear less sharp compared to other modes.

The following point cloud settings are only available for data captured with NavVis VLX:

  • High Confidence: In this mode only points with high confidence are retained and regions that have not been scanned densely are removed. This mode is recommended for narrow indoor environments.

  • Standard: This mode is for general use and yields high-quality point clouds in a wide range of scenarios. This mode is recommended for larger indoor environments.

  • Outdoor: In this mode points from sparsely scanned areas are retained. This mode is recommended for outdoor environments.

Panorama Settings

The following panorama settings are available for data captured with NavVis M6 and NavVis VLX:

  • Floor Filling
  • Include panoramas in .e57 point cloud

Control Points File Structure

TXT Files

To avoid problems with processing, a control points file in .txt format needs to be structured in the following way:

  • The file needs to have four columns with the control point name first followed by the x,y and z coordinates.

  • The columns need to be separated by at least one space.

  • Decimal places need to be indicated by periods. Commas are not allowed.

CSV Files

To avoid problems with processing, a control points file in .csv format needs to be structured in the following way:
  • The file needs to have four columns with the control point name first followed by the x,y and z coordinates.

  • An optional header line (similar to: id, x, y, z) describing the columns can be present.

  • Data beyond the fourth column will be ignored.

  • Empty rows will be ignored.

  • Fields should be separated by commas. Semicolons are supported but not suggested.

  • Decimal places should be indicated by periods. Commas are supported but not suggested.

Resolving Problems with Control Points

When you upload a control points file, the file will be validated. If there are any warnings or errors you can deselect or edit the control points that are causing problems.

Excluding Control Points from Processing

Follow these steps to exclude control points from processing.
  1. In your processing task, click View control point configuration.
  2. Deselect the check boxes next to the control point(s) you want to exclude from processing.
  3. Click Save changes.

Renaming Control Points

If control points could not be found, this might be due to inconsistent naming. For control points to be recognized by the system the names that appear in the control points file need to correspond to the names used during mapping.

Follow these steps to rename control points:

  1. In your processing task, click View control point configuration.
  2. Click the pencil icon next to the control point that you want to rename.
  3. In the window that opens, select the new name for the control point.
  4. Click Rename.
  5. Click Save changes.

After Processing

After processing your data, you can download the processed data and copy it to Dataset Management to view it in your NavVis IVION site.

Adding Processed Data to Dataset Management

Follow these steps to add the processed data to Dataset Management:
  1. Go to Site Setup > Processed Data.

    • Control points optimization log: the log file generated during the optimization stage of post-processing

    • Control points verification log: the log file generated during the verification stage of post-processing

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

    • 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

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

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

    • Other files: you can download panorama images by selecting Panorama images (.zip) from the list of data formats.

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

    • .e57

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