Upload NavVis VLX from NavVis Desktop App

TABLE OF CONTENTS

Prerequisites

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

1. Unstructured point cloud in PLY or E57 format.

2. Walking /scanning path in CSV format.

3. CSV file is usually included in the same folder that contains panoramic images. Look for a folder called pano or panoramic images where raw files for Indoor Mobile device are stored.


Note: If this CSV file is not included in the same folder as the panoramic image, make sure that it contains the path to the images in the right folder. For example, the images could be located 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: geolocation information in XML format.

  • 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 an E57 file as an export from registration software.
  • This XML file may have a _bundle in it for NavVis data.
  • In XML file all scanning sessions are listed with corresponding position and orientation.
  • This data will be used by Cintoo Connect for the restructuring process followed by the point cloud-to-mesh transformation and upload to Cintoo.

Upload NavVis Scans Processed in the NavVis Desktop App

1. Open Data tab and click Prepare & upload on the Mobile laser scans tile or click Mobile scan from Add drop-down menu on the top right. Cintoo Connect will launch.

 

2. In Mobile Laser Scans tab in Cintoo Connect, select NavVis VLX and M6 as Device/Format.


3. Select E57 or PLY file as input for Point Cloud.


4. Select CSV file as Scanning Path.

 

5. Modify position sampling value as needed by entering a value into Generate a virtual vantage point for 1 of__ position. 

 

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


6. Enable or disable Blur faces.


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


7. Enable or disable Import all 360 Images.


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


8. Modify Data to process in parallel value as needed and according to available PC cores. 


9. Click Import.

  • New 3D scans will appear one by one in Cintoo project
  • Check Messages tab from time to time to confirm the process is running smoothly.

Uploading NavVis Scans from Multiple Walks/Sessions

If scanning was performed in multiple sessions, it is essential to get each point cloud (in PLY or E57) one by one together with a corresponding scanning path.


Geolocation XML 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: it is possible to run several Cintoo Connect import sessions in parallel if the PC has enough capacity.
