AR Dataset

AR Dataset is a sub-package of VLSDK that handles AR-specific datasets recorded from the device's screen and movements. Since VLSDK includes logic to improve localization accuracy based on the actual device's movements, developing with the AR Dataset allows you to work in an environment similar to using a real device.

AR Dataset consists of Recorder and Player. The Recorder is provided as VLSDK > ARDataset > ar-dataset-recorder-0.9.5.unitypackage within the VLSDK package. The Player is already included in VLSDK and can be found under VLSDK > Player.

Recorder​

To use the Recorder, you need to use the ar-dataset-recorder-0.9.5.unitypackage included in VLSDK. Opening the package will add files related to Recorder. Open the Recorder > Scenes > Recorder.unity scene to see a screen implemented like a camera app.

If you build and run this scene on iOS or Android, you can generate datasets. Start recording by pressing the record button, and after stopping the recording, the results will be saved on the device. You can transfer the recorded results to a PC using the following methods:

  • iOS Environment
    • Open the default Files app on iOS and share the folder of the recording app name to the PC.
  • Android Environment
    • Open a file browser app and navigate to Android -> media -> 'app bundle name' to access the files and share them to the PC.

Player​

To use the Player, the ARDatasetManager must be added to the Scene. Click GameObject > ARC-eye > Dataset > Create ARDatasetManager to add the ARDatasetManager to the Scene.
