What is patched in the OpenNI Binaries

Hi,

Just saw that the OpenNI binaries that one can download from the PCL website say that they are patched. What hast been changed? should I use these even though I do not use PCL to capture coulds via OpenNI?

Thanks
Chris

They have been patched to support the Kinect, different frame rates,
higher resolutions and more. You can find the complete patch here:

Is this any different from avin/sensorkinect?

I am using Avin2's patched driver too. Are there any stability or performance patches we should know of? I looked over the patch descriptions and could not find any useful information.

thanks

Hi Joseph,
I am trying to use the patched openni drivers for xbox kinect on arch linux. I installed it using
hg clone https://kforge.ros.org/openni/drivers openni_drivers -r 252
cd openni_drivers
sudo make install_engine

But when i run the openni viewer i.e. pcl_openni_viewer it pops this
"pcl_openni_viewer: symbol lookup error: /usr/lib/libpcl_io.so.1.6: undefined symbol: xnContextAddRef"

any ideas what could be wrong
thanks in advance

try -r 295, that should be the version used in the PPA.

You have to recompile PCL after changing OpenNI.

hi,
there seems to be a problem. my system is 64 bit but it tries to install 32 bit version.
the makefile contains 'lsb_release -sc' which is not available as arch is rolling release
is there a getaround or a different way to install the patched openni binaries in arch linux.

also i am getting the following error

cd build/openni/Platform/Linux-x86/CreateRedist && ./RedistMaker && cd -
  File "Redist_OpenNi.py", line 145
    print "failed to execute: " + cmd
                              ^
SyntaxError: invalid syntax
make[1]: *** [installed] Error 1

thanks
vivasvan

Can you explain a little more?

Just put in some name, it's not important.

There seems to be an AUR, but I'm not a arch user.

I guess python is pointing to 3.x, you need 2.x for this.

@Jochen thanks for the python tip, i managed to do it with python-virtualenvwrapper. make completed successfully. however sudo make install gives the following. error occurs at last line

sudo mkdir -p /usr/include/openni \
                                                        /etc/openni \

sed: -e expression #1, char 26: unknown option to `s'
make: *** [install_openni] Error 1

i checked the openni install.sh has no sed commands.
any ideas where is is going wrong
fyi i am using this wiki http://www.ros.org/wiki/openni_kinect for installation

thanks
vivasvan

You set $DISTRO to "n/a" resulting in a superfluous / in the sed
expression, set it to arch or something and it should work.

@Jochen, thank you for bearing with me, kinect is working smoothly now.
one last question though..
http://www.ros.org/wiki/openni_kinect  further mentions the following two steps

2. Checkout the source onto your ROS_PACKAGE_PATH:
hg clone https://kforge.ros.org/openni/openni_ros
3. Compile everything:
 rosmake openni_kinect --rosdep-install

what do they do?
i have rosinstall installed, but rosmake is still an unrecognized by bash. without going through the above steps my kinect is working fine (i checked it with pcl_openni_viewer). although it shouldn't concern me but  knowing this would help me increase an understanding about the process and i too may be of help to somebody.

thanks
vivasvan

This is only needed when you want to use openni with ros.
