我已经在OSX 10.11.5上设置了libfreenect2,并且可以成功运行Protonect演示以显示RGB/IR/深度流,但是我也想使用OpenNI/NITE进行骨骼跟踪。

我遵循了针对OpenNI的repo的README文件中的说明,但是当我尝试运行NiViewer时,得到了以下信息:

NiViewer
openDevice failed:
    DeviceOpen using default: no devices found

Press any key to continue . . .

我目前正在遍历github上的libfreenect2问题,并记录我正在尝试的内容和结果here。任何提示/技巧都是有帮助的。

在OSX上使用Kinect v2用libfreenect2设置和测试OpenNI/NITE的最简单方法是什么?

原来我应该使用NiTE2.2时才使用NiTE 1.5
我只是简单地将libfreenect2-openni2.0.dyliblibfreenect2/build/lib复制到NiTE-MacOSX-x64-2.2/Samples/Bin/OpenNI2/Drivers/,然后运行SimpleUserTracker示例,就可以了!

还有一个问题:仅打印到控制台的示例会运行,但是打开窗口并渲染的示例不起作用。没有渲染任何窗口,就好像该线程被某种方式阻塞了一样。
那就是我使用集成的Intel GPU的时候。如果我使用离散的nVidia GPU,应用程序将崩溃:

我该如何解决这个问题?

最佳答案

供引用的是上述注意事项。
这是我使用libfreenect2及其OpenNI2驱动程序来获取OpenNI2/NITE2.2骨架跟踪的方法。我有:

  • 通过自制程序编译安装了OpenNI2,并按照github repo's readme instructions
  • 编译了具有OpenNI2支持的libfreenect2
  • 下载了NITE2.2(取代了我之前滥用的Nite1.5)
  • 将libfreenect2 OpenNI2驱动程序(ibfreenect2/build/lib/libfreenect2-openni2.0.dylib)复制到需要运行NITE2的Drivers文件夹中(例如NiTE-MacOSX-x64-2.2/Samples/Bin/OpenNI2/Drivers)。

  • 我通过在OpenNI.ini中将日志级别设置为详细来弄清楚路径是错误的:
    [Log]
    ; 0 - Verbose; 1 - Info; 2 - Warning; 3 - Error. Default - None
    Verbosity=0
    LogToConsole=1
    LogToFile=1
    
    [Device]
    ;Override=""
    
    [Drivers]
    ; Location of the drivers specified by a relative path based on OpenNI's shared library or an absolute path.
    ; Path separator "/" can be used to be portable for any platforms.
    ; Default - OpenNI2/Drivers
    Repository=OpenNI2/Drivers

    同样,一旦libfreenect2在openni2支持下进行编译,它甚至可以在Processing中使用,只需将libfreenect2-openni2.0.dylib放到/Documents/Processing3/libraries/SimpleOpenNI/library/osx/OpenNI2中(在OSX上):
