Setting Up NavVis Positioning (Enterprise Only)

Positioning services are available for indoor sites or building complexes mapped with NavVis technology.

NavVis Positioning enables visual 6D positioning in NavVis IVION. This means that, given one or multiple query images, the full 3D location and 3D orientation of the client device at the time of positioning are reconstructed.

The following documentation describes how to set up NavVis Positioning for your NavVis IVION site(s).

Prerequisites​

To use NavVis Positioning you need:

  • A NavVis IVION Professional or NavVis IVION Enterprise instance

  • A Visual Index (image database) generated from your mapped data.

  • A navigation graph generated for all sites.

Generating a Visual Index​

To set up NavVis Positioning, you first need to generate a Visual Index for the bundles that you want to use for positioning.

Follow these steps to generate a Visual Index from your mapping data:

Note: For a NavVis IVION instance migrated from 2.x, visual indices must be reprocessed.
  1. In your NavVis IVION site, go to Site Setup > Dataset Management.
  2. Click Advanced next to the bundle for which you want to generate a Visual Index.
  3. Select Create visual index from the drop-down menu.

After you have generated a Visual Index you can view its status below the bundle name:

  • Positioning is available for this bundle.

  • Please update the Visual Index in order to use NavVis Positioning: Follow the steps above.

  • Nothing: There is no Visual Index for this bundle. If you want to enable NavVis Positioning, follow the steps above.

Uploading a Visual Index​

You need a continuous internet connection to enable communication between your server machine and the cloud-based NavVis Image Description Service.

Note: Communication between your data processing machine and the NavVis Image Description Service enables a Visual Index to be generated during processing. For security reasons and data protection, all communication with the NavVis Image Description Service is SSL-encrypted.

If you have generated a Visual Index locally, you can upload it to the existing bundle in your NavVis IVION site.

Follow these steps to upload a Visual Index to NavVis IVION:

  1. Go to Site Setup > Dataset Management.
  2. Click Advanced next to the bundle for which you want to upload a Visual Index.
  3. Select Upload visual index from the drop-down menu.
  4. Select the .nvi file you want to upload.
  5. Click Upload.
    If there is an outdated Visual Index available, it will be automatically overwritten.
  6. Repeat these steps for each bundle.

Deleting a Visual Index​

Follow these steps to delete a Visual Index from NavVis IVION:

  1. Go to Site Setup > Dataset Management.
  2. Click Advanced next to the bundle for which you want to delete a Visual Index.
  3. Select Delete Visual Index from the drop-down menu.
