如何使用libfreenect2设置OpenNI2和NITE在OSX上进行骨架跟踪？

Question

我刚刚在OSX 10.11.5上设置了libfreenect2,我可以成功运行显示RGB/IR /深度流的Protonect演示,但我也想使用OpenNI/NITE进行骨架跟踪.

我按照repo的README文件中的说明进行了OpenNI,但是当我尝试运行NiViewer时,我得到了这个:

NiViewer 
openDevice failed:
    DeviceOpen using default: no devices found

Press any key to continue . . .

目前我经历libfreenect2问题在GitHub和记录我尝试和成果在这里.任何提示/提示都很有帮助.

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

原来我的时候,我应该一直在使用NiTE2.2我只是复制使用NITE 1.5 libfreenect2-openni2.0.dylib从libfreenect2/build/lib给NiTE-MacOSX-x64-2.2/Samples/Bin/OpenNI2/Drivers/然后跑了SimpleUserTracker样品和它的工作!

还有一个问题:只打印到控制台的样本运行,但打开窗口和渲染的样本不起作用.没有窗口呈现,好像该线程以某种方式被阻止.那是我使用集成的Intel GPU的时候.如果我使用离散的nVidia GPU,应用程序崩溃:

我怎样才能解决这个问题？

Answer 1

这里作为参考,作为参考.这就是我用libfreenect2和它的OpenNI2驱动程序进行OpenNI2/NITE2.2骨架跟踪的方法.我有:

1. 根据github repo的自述文件说明,通过自制程序编译已安装的OpenNI2并编译了具有OpenNI2支持的libfreenect2
2. 下载NITE2.2(取代之前我错过的Nite1.5)
3. 将libfreenect2 OpenNI2驱动程序(ibfreenect2/build/lib/libfreenect2-openni2.0.dylib)Drivers复制到我需要运行NITE2 的文件夹(例如NiTE-MacOSX-x64-2.2/Samples/Bin/OpenNI2/Drivers).

我已经通过在OpenNI.ini中将日志级别设置为详细来找出路径错误:

[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

Symon Kaliski跟随笔记并使用OpenFrameworks 在OSX上用骷髅跟踪文章写了一个精彩的Kinect 2,请务必查看!

此外,一旦使用openni2支持编译libfreenect2,它甚至可以在Processing中使用,只需删除libfreenect2-openni2.0.dylib /Documents/Processing3/libraries/SimpleOpenNI/library/osx/OpenNI2(在OSX上):
