HoloLens with ARToolKit

Author: Long Qian

Date: 2017-02-14

Overview

HoloLensARToolKit is a successful experiment to integrate ARToolKit (v5.3.2) with HoloLens, or generally UWP (Universal Windows Platform).

With fiducial marker tracking provided by ARToolKit, plus the indoor localization of HoloLens, many Augmented Reality applications would be made possible.

This repository contains:

  • Wrapper of ARToolKit5 for UWP
  • Unity package to interface the native library
  • Some sample Unity scenes to demo the use of them
  • Link to camera calibration of HoloLens

Example

Minion on the Cube (Youtube Video) HoloLensARToolKit Samples (Youtube Video)

Run the sample

  1. Make sure you have HoloLens development tools installed.
    • HoloLens Emulator and Vuforia are not required.
  2. Launch Unity3D, open project folder HoloLensARSample.
  3. Import the unity package ARToolKitUWP.unitypackage.
  4. Open one of the sample scenes
    • Assets/Sample/HoloLensARToolKitSingle.unity
    • Assets/Sample/HoloLensARToolKitCube.unity
    • Assets/Sample/HoloLensARToolKitMulti.unity
  5. Configure HoloLens deployment settings and deploy to HoloLens.
  6. Prepare the correspondent printed marker of ARToolKit.
    • Marker images are Here.
    • Make sure the printed marker size is same as configured in Unity.
  7. See the effect.
    • HoloLens clicker or air tap is able to tune the visualization of camera frame.
