Simulation Data Capture

Record localization simulation data at a physical location with the MultiSet app, then replay it in the Developer Portal or the Unity Editor.

Simulation data is a short recording of camera frames and sensor data taken at a physical location. Once captured, you can replay it against any of your maps to test localization without standing in the space again, either in the Developer Portal or in the Unity Editor.

The MultiSet app is the quickest way to record it, no build required.

How to Capture Simulation Data

1. Download the MultiSet App: Install the MultiSet application on your mobile device.

2. Start a New Capture: Open the app and tap the + button to begin a new session.

3. Choose "Simulation Data": From the options presented, select "Simulation Data." This will open an AR scene using your device's camera.

4. Position Yourself: Walk to the physical location where you want to capture the simulation data.

5. Capture the Data: Tap the Capture button. The app will record simulation data for a few seconds.

6. Name Your Simulation: A pop-up will appear after the capture is complete. Give your simulation a descriptive name so you can easily identify it later.

7. Upload: Finalize the process by uploading the captured data.

8. Repeat: You can repeat this process at every location where you want to capture simulation data for later testing.

Where Your Captures Go

Captured datasets are tied to your account, not to a single map, so anything you record can be run against any of your maps or MapSets. Uploads are available immediately, in two places:

• Developer Portal: Open a map or MapSet, choose Simulation, and run any dataset against it as a single frame or multi frame query to compare pose accuracy and confidence. See Simulation.

• Unity Editor: Use the SimulationDataManager component to fetch and download your captures, then localize in Play mode without leaving your desk. See Localization Simulation.

You can also record simulation data from your own Unity build using the SimulationDataCapture scene in the MultiSet Unity SDK. See Build a simulation data capture app.
