前提条件

次のソフトウェアがインストールされていることを前提条件とします。インストールのパスが異なる場合は適宜読み替えて下さい。


Unity内でDLLを利用する

NtKinectDLL 経由で Kinect V2 を利用する Unity のプロジェクトを作成します。

  1. [重要] NtKinectDLL の最新版をコンパイルして、NtKinectDLL.dll を作成して下さい。 実行に必要なライブラリのパスが私のコンパイル環境と同じ場合は、バイナリをダウンロードすることもできます。
  2. Unity で DLL を利用する方法の詳細については 公式のマニュアル を一読しておくことを勧めます。
  3. Unity(C#) のデータは managed (ガベージコレクタによって管理されており場所を移動することがある) な状態であり、DLL(C++) のデータは unmanaged (場所が移動することはない) な状態です。 この間でデータを受け渡すには、状態を変換する必要があり、 それにはC# の System.Runtime.InteropServices.Marshal クラス のメソッドを利用します。

    C#と他の言語の間でデータを受け渡しを行うには、 Blittable type な変数を用います。

  4. Unity の新しいプロジェクトを開始します。ここではプロジェクト名は NtKinectUnity としています。



  5. ProjectのAssets/Plugins/x86_64/の下に NtKinectDLL.h, NtKinectDLL.lib, NtKinectDLL.dll を置きます。(2017/09/08 変更。NtKinectDLL.dll だけでOKです。)
  6. NtKinectDLL/x64/Release/の下から NtKinectDLL.dll, NtKinectDLL.lib を、 NtKinectDLL/NtKinectDLL/ の下から NtKinectDLL.h をコピーします。 (2017/09/08 変更)







  7. Project の Assets/Plugins/x86_64 の下に、KinectV2の顔認識ライブラリを全てコピーします。
  8. 「$(KINECTSDK20_DIR)Redist\Face\x64\の下の全てのファイル」をコピーします。

    [注意]$(KINECTSDK20_DIR)は手元の環境では "C:\Program Files\Microsoft SDKs\Kinect\v2.0_1409\" に設定されています。 各自の環境にしたがって読み替えて下さい。




  9. Project の Assets/Plugins/x86_64 の下に、KinectV2のジェスチャー認識ライブラリを全てコピーします。
  10. 「$(KINECTSDK20_DIR)Redist\VGB\x64\の下の全てのファイル」をコピーします。

    [注意]$(KINECTSDK20_DIR)は手元の環境では "C:\Program Files\Microsoft SDKs\Kinect\v2.0_1409\" に設定されています。 各自の環境にしたがって読み替えて下さい。




  11. ProjectのAssets/Scripts/の下に C# のスクリプトを生成する。
  12. 上部のメニューから「Assets」-> 「Create」 -> 「C# Script」 -> ファイル名は NtUnity

  13. ProjectのAssets/Scripts/の下に C# のスクリプトを生成する。
  14. 上部のメニューから「Assets」-> 「Create」 -> 「C# Script」 -> ファイル名は Sample01

    Sample01.cs
    using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;
    
    public class Sample01 : MonoBehaviour {
      NtUnity.Kinect nt;
      void Start () {
        nt = new NtUnity.Kinect();
      }
      void Update () {
        nt.setRGB();
        nt.setSkeleton();
        nt.setFace();
        nt.imshowBlack();
        Debug.Log("n = " + nt.skeleton.Count);
      }
      void OnApplicationQuit() {
        nt.stopKinect();
      }
    }
    
  15. Hierarchy に Empty Object を配置して、名前を GameController に変更します。 そして、Hierarchy中の GameController にProjctsのAssets/Scripts/Sample01.cs をコンポーネントとして追加します。
  16. シーンを Sample01.unityという名前で保存します。
  17.   Files -> Save Scene as .. -> Sample01
    
  18. 実行すると、Kinect V2が取得した RGB 画像が別ウィンドウに表示され、 骨格や顔の認識状況がそのウィンドウに表示されます。 Unity Editorのコンソールに、認識できた骨格の個数が数字で出力されます。
