我正在使用 Ubunut 14.04 并安装了 OpenNI 2.2、NITE 2.2 和 primesense2.2.0.30-5 ( https://pypi.python.org/pypi/primesense/2.2.0.30-5 )

上面提到的示例程序运行良好，但是当我尝试使用初始化 nite2 时，程序崩溃了。

这是代码：

from primesense import openni2, nite2

openni2.initialize()     # can also accept the path of the OpenNI redistribution
nite2.initialize()

if (nite2.is_initialized()):
    print "nite2 initialized"
else:
    print "nite2 not initialized"

dev = openni2.Device.open_any()
print dev.get_sensor_info(openni2.SENSOR_DEPTH)

depth_stream = dev.create_depth_stream()
depth_stream.start()
frame = depth_stream.read_frame()
frame_data = frame.get_buffer_as_uint16()
depth_stream.stop()

openni2.unload()

错误报告 ：

Traceback (most recent call last):
File "test.py", line 4, in <module>
nite2.initialize()
File "/usr/local/lib/python2.7/dist-packages/primesense/nite2.py", line 81, in initialize
("\n    ".join("%s: %s" % (dir, ex) for dir, ex in exceptions)),)

OpenNI2-FreenectDriver: Closing device freenect://0

我想要用于用户跟踪和手部跟踪的 nite python 绑定。有没有人成功完成过

一种解决方法是从 primesense python 绑定中注释文件 _openni2.py 中的以下行：

global _niteDumpUserTrackerCalibrationDataToFile
_niteDumpUserTrackerCalibrationDataToFile = dll.niteDumpUserTrackerCalibrationDataToFile
_niteDumpUserTrackerCalibrationDataToFile.restype  = NiteStatus
_niteDumpUserTrackerCalibrationDataToFile.argtypes = [NiteUserTrackerHandle, NiteUserId, ctypes.c_char_p]

此外，请确保在与 python 脚本相同的目录中具有 NiTE2 库和文件夹（存档中的 Redist/NiTE2）的副本/符号链接。
