Question

我有兴趣在Unity中使用Kinect for Windows显示深度数据。不幸的是，我有Kinect v1.8，我知道这很容易用Kinect V2（Kinect Fusion）完成。

我找到了这个例子：https://github.com/rickbarraza/UnityKinectDepthExplorer 我安装了所有必要的组件，现在获得了DLLNOTFOUNDEXCEPTION：

无法加载资产/插件/ x86_64 / KinectUnityAddin.dll＆＃39;

关于我到目前为止所阅读的所有帖子和论坛，这是因为我使用的是SDK 1.8（而不是SDK 2.0）。

有什么办法可以在Kinect v1.8中使用这个例子吗？我试图联系作者，但他还没有回复。

非常感谢！

我在大学项目中遇到了同样的问题，这对您来说不迟到。这是我制作的Kinect v1.8包装器，只能读取kinect深度图像。我使用了来自Unity-Assetstore的Kinect和MS-SDK作为定向，您不必下载它。您只需要此代码。使用Init（）方法启动并使用GetDepthArray（）函数获取深度帧。希望它对您有用！

您必须安装Kinect 1.8 sdk或Windows / System32文件夹中至少具有1.8 sdk中的Kinect10.dll
