Upload NavVis VLX from NavVis Desktop App

TABLE OF CONTENTS

• Prerequisites
• Upload NavVis Scans Processed in the NavVis Desktop App
• Uploading NavVis Scans from Multiple Walks/Sessions

Prerequisites

The following files are required needed upload the NavVis scans processed in the NavVis Desktop App:

1. The unstructured point cloud in PLY or E57 format
2. The walking /scanning path in CSV format
3. This CSV file is usually included in the same folder that contains the panoramic images.
   • You may want to look for a folder call ‘pano’ or ‘panoramic images’ where the raw files for your Indoor Mobile device are stored.
   • Note: If this CSV file is not included in the same folder than the panoramic image, make sure that it contains the path to the images in the right folder. For example, you can have the images in a ‘pano’ folder, under the folder where the CSV file is. If all the image filenames are prefixed with ‘pano/’ in the CSV file, the import workflow will work.
   • Example content:
     
     
4. Optional: The geolocation information in XMLformat
   • This geolocation information is usually produced while putting multiple scanning sessions in the same coordinate system.
   • For single scanning sessions, this geolocation information is also produced when specifically requesting the E57 file as an export from your registration software.
   • This XML file may have an ‘_bundle’ in it for NavVis data.
   • Opening this XML file, you should see all scanning sessions being listed with some position and orientation for each.
   • This data will be used by Cintoo Connect for the restructuring process followed by the point cloud-to-mesh transformation and the upload to Cintoo Cloud.

Upload NavVis Scans Processed in the NavVis Desktop App

1. Open your Cintoo project to the Data tab.

2. In your selected project and Work Zone, click "Prepare and upload" under Mobile Scanner, or select "Upload indoor mobile scanner" from the drop-down list.

3. Cintoo Connect will open at the "Mobile Laser Scans" tab. Select "NavVis VLX and M6" as the Device / Format.

4. Adjust the process in parallel setting to process more than 2 scans (default setting) in parallel if you have a multi-core PC. 

5. Select the E57 or PLY file as input for Point Cloud:

6. Click the ellipsis to select the CSV file as input for Scanning Path.

7. Modify the ‘Positions sampling’ value as needed:

• For example, "1 of 1 position" will create 1 Virtual Vantage Point (VVP) in Cintoo for every position included in the scanning path CSV. "1 of 4 positions" will create 1 VVP at every 4th position included in the scanning path CSV.
• The number of VVPs and average distance between each one will be indicated in Cintoo Connect and will be added to your scan count.

8. Enable/disable "Blur faces." 

• It is checked by default, thus enabling the automatic blurring of people captured in any panoramic images included in the scans being uploaded to Cintoo.
• Uncheck this option to prevent the automatic blurring any people in the panoramic images.
• Blurring cannot be undone in Cintoo after the scans have been uploaded.
• Any files uploaded without the 'Blur faces' option enabled must be deleted from the Cintoo project and re-uploaded with the option checked in order to apply automatic blurring.

9. Enable or disable "Import all 360 Images":

• This option is checked by default, enabling the import of all 360 images included in the scans, even if the using a position sampling value other than 1 of 1 position.
• Uncheck this option to prevent the automatic import of all 360 images included in the scans .
• 360 images uploaded with this option will count against the 360 Images capacity of the Cintoo account, not the Scan Capacity.
• 360 images uploaded with this option will not contain any 3D data. Only the panoramic image will be displayed, so 3D display settings, Measurements, and Annotations cannot be used at these positions.

10. Click ‘Import’.

• Check the ‘Messages’ tab from time to time to see if the process is running smoothly.
• Your new 3D scans will appear one by one in your Cintoo project.

Uploading NavVis Scans from Multiple Walks/Sessions

• If you have performed your scanning in multiple sessions, you will need to bring each point cloud (in PLY or E57) one by one together with the scanning path for each (item 2 above).
• The geolocation XML(item 3 above) will also be mandatory in this case for each E57 import.
  • Cintoo Connect will look for each point cloud file name in the XML file.
• Note that you can run several Cintoo Connect import sessions in parallel if your computer has enough capacity.
