Workflow and Limitations

A quick look at our SDK.

Basic Workflow

The process to enable persistent AR in a space can be divided into two main parts.
  • Mapping a location.
  • Finding the device position and orientation (localizing) within the location using the constructed map.
Our SDK provides functions for both mapping and localizing.
When mapping a space with our SDK, the images are sent to our servers for map construction.
After construction, the map can be downloaded from our servers. You can either download and embed the map into your app for full offline use or download the maps at runtime.
Localization can be done on device or on our servers depending on your needs.

Mapping

When mapping with the Immersal Mapper app, images are temporarily stored on the device and queued for uploading to the Cloud Service. The In Queue value in the workspace info panel tells you how many images are stored on the device, waiting to be uploaded.
After images are uploaded to the Cloud Service, they are stored in what we call a workspace. The workspace is a container for all the input data the maps are constructed from. The Uploaded Images value in the workspace info panel tells you how many images have been uploaded and stored in the workspace.
After you have captured the necessary images, you then submit the workspace content for map construction. At this point, the data is copied and a new map construction job is created. You can then see the map construction job appear on the map list in the Immersal Mapper app or the Developer Portal. When the map construction job has been created, you can safely delete the images from the workspace and start mapping a new location.
You can restore data from existing map construction jobs to the workspace. This is useful when you want to update or expand existing maps.

Localization (visual positioning)

Localization uses map files that can be downloaded from the Developer Portal or by using the REST API.
For more information on how the set up localization, see The Multimap Sample.
The Mapping App also includes a mode to test and visualize constructed maps.
