Implementing a Dataset App

In this tutorial, you will implement the 2.Dataset sample project that allows testing with ARDataset, and learn how to integrate ARDataset. Using Dataset mode, you can develop a similar AR experience to the actual environment even without a real device.

note

Before starting this tutorial, you must complete Implementing a Simple App.

1. Recording a Dataset​

To use Dataset mode, you need data recorded through the ARDataset Recorder. Please refer to this documentation for how to record data using the ARDataset Recorder.

2. Adding the Player Package​

To use Dataset mode, you must first add the Player package to your project.

note

If you installed VLSDK using the Custom Package method, all sample projects are included by default, so you don't need to perform the steps below.

2.1 Installing the ARDataset Player Package​

  1. Select Window > Package Management > Package Manager.

  1. In the Package Manager window, select the VLSDK package and then select the Samples tab.

  2. Find ARDataset Player among the sample projects and select the Import button.

3. Adding ARDatasetManager​

ARDatasetManager plays a role in playing AR datasets created in Dataset mode and restoring various sensor information from the time of recording.

3.1 Creating ARDatasetManager​

  1. Right-click in the Hierarchy window and select GameObject > ARC-eye > Dataset > Create ARDatasetManager. Through this process, you can add the ARDatasetManager object to the scene.

3.2 Setting up Custom Pose Tracker Adaptor​

  1. VLSDK basically uses Texture Provider to send VL requests. To change this, add a Custom Pose Tracker Adaptor component to VLSDKManager.

  1. Check the Use Custom Editor Pose Tracker item. If the ARDataset Player package has been added correctly, you can find the ARCeye.Dataset.ARDatasetPoseTracker item. Select that item.

alt text

Now in the Editor environment, you will use the PoseTracker based on ARDataset.

4. Connecting the Dataset​

Connect the recorded dataset to ARDatasetManager to enable playback in the Editor.

4.1 Selecting the Dataset File​

  1. Select ARDatasetManager and click the Select Dataset Directory button.

  1. When the dataset selection popup appears, select the dataset directory you created in advance.

alt text

  1. When you enter Play Mode, the dataset will be played and you can verify that VLSDK operates similarly to the actual AR environment even in the Editor environment.

5. Conclusion​

You can now test and develop AR functionality without a real device even in the Editor environment using ARDataset. Using Dataset mode can greatly improve development speed, and you can proceed with development efficiently by reusing datasets recorded in various environments.
