Hi @poine! Thank you very much! It works now...
For future reference (if anyone in the future has trouble with the same thing), this is what I did:
Installed libfreenect:
sudo apt-get install libfreenect-dev
sudo apt-get install ros-indigo-freenect-launch
Then I created a file called kinect_orbslam.launch with the contents described by poine, and launched it through roslaunch kinect_orbslam.launch.

You don't need to change it in the code and recompile, you can always convert one topic to another using ":=" while running ORBSLAM.
for example:
rosrun ORB_SLAM2 Mono Vocabulary/ORBvoc.txt Examples/Monocular/demo_cam.yaml /camera/image_raw:=/usb_cam/image_raw
This converts a published topic in /usb_cam/image_raw to the desired one , /camera/image_raw , in runtime.

@poine https://github.com/poine, I have the following questions:
- Did you use ORBSLAM 1 or 2?

Did you install any package for kinect?

- What were the steps for you to launch OrbSLAM with kinect? roscore
followed by OrbSLAM launch? Or did you run anything else such as the
freenect package?you need to start the freenect node, see the freenect_launch package
- Did you ever encounter the "Waiting for Images" displayed in the GUI
that opens while running OrbSLAM2?that happens if orb_slam is not receiving images on the topic it is
expecting them ( "/camera/rgb/image_raw" and
/camera/depth_registered/image_raw" )
this is my launch file:
<!-- use device registration -->
<arg name="depth_registration" value="true" />
<arg name="rgb_processing" value="true" />
<arg name="ir_processing" value="false" />
<arg name="depth_processing" value="false" />
<arg name="depth_registered_processing" value="true" />
<arg name="disparity_processing" value="false" />
<arg name="disparity_registered_processing" value="false" />
<arg name="sw_registered_processing" value="false" />
<arg name="hw_registered_processing" value="true" />

Hi @poine https://github.com/poine, I am using kinect v1, why? Are you
considering to use v2?I am looking at some Ebay auctions. Seems you can get v2 kinects for cheap.
So... yes, I might try that.By the way, I just tried your modified version, it worked! The system
launches much faster now, thank you!I am glad it worked for you, and you're very welcome.
Since you are also working with a similar setup, did you find out how to
publish ORBSlam data into a ROS topic? Since I am new to ROS, I've been
struggling a lot to figure out how to get pose of the system as an ouput of
ORBSLAM.
I am working on that at the moment. I did not push the code to github yet
as I changed a bunch of things to make the Pangolin viewer optional (I can
not run it on my robot) and reintroduce ROS publishers that were in the
first version of ORB SLAM. I would prefer to discuss with Raul and get the
startup patch accepted before submitting another (larger) patch.
I would like to formalize a generic viewer interface to ORB SLAM2 so that i
can use either Pangolin, or ROS, or nothing.
Let me know if you get desperate about ouptut to ROS and I'll push my
current code to github.
from orb_slam2.
@poine, I do have a Kinect v2 here (which, by the way, was never taken out of the box). I will try to use it later, I'll let you know the outcome!
I understand your concern about getting the startup patch accepted before submitting this new one. I am not desperate, but I would be curious to play with it. Take your time! ;-)

@mohammed Alshiekh
ok, i will try to put something in my git. What is it exactly you want to
do? run without the pangolin graphical interface and publish ORBSLAM poses
to ROS?

@chwimmer thakn you very much! It works now.
I change the topic from"/camera/rgb/image_raw and camera/depth_registered/image_raw" to the topics of kinect2, then ecompile.

Nobody has had any experience concerning OrbSlam2 + kinect? I still haven't figured it out =/

i played with orbslam and kinect last week end. what is your question?

As I said in the initial post, I was able to run the OrbSLAM2 examples, but I wasn't able to run OrbSLAM2 in real time with my kinect camera.

@marcelinomalmeidan , you're very welcome. By the way, are you using a
kinect v1 or v2?
And if you have a minute, could you test that version of ORB_SLAM2 :
https://github.com/poine/ORB_SLAM2 ? It starts immediately. (the pull
request is here: #21)

@poine Yes, I'd like to have the poses published onto a ROS topic. Is it possible to have them both working at the same time? That is the graphical interface and ROS?
Thanks!

@poine @marcelinomalmeidan Great, thank you so much!
from orb_slam2.
@poine @marcelinomalmeidan ,hi ,I am new to the orbslam2. I am trying to use kinect2 to run orbslam2.I followed the site :https://github.com/raulmur/ORB_SLAM2/blob/master/README.md. but it doesn`t work,the camera window displays "Waiting for Images". I already checked rostopic list, which gives:
/camera/depth_registered/image_raw
/camera/rgb/image_raw
/rosout
/rosout_agg.
I have been puzzled for several days.do you succeed in running orbslam2 with kinect2?Could you give me a favor? Thanks.
from orb_slam2.
Hello @Mrzzhao,
it seems that you didn’t start the driver of the Kinect2. You only started ORB_SLAM2.
Thats easy to check if you type:
rostopic info /camera/rgb/image_raw
Now check if there is a Publisher. When I'm right there only should be a Subscriber.
from orb_slam2.
@chwimmer ,thank you, I tried it ,the topic /camera/rgb/image_raw exists. And there are many types of messages. Today I tried another orbslam2 by Gaoxiang,and it works.Thank you again.Furthermore,I will try to solve this problem .I will tell you if I work it out.
from orb_slam2.
@poine @marcelinomalmeidan @chwimmer Hi ,I meet the same problem! I am also trying to use Kinect2 to run ORBSLAM2.It works well when I choose TUM Dataset, but it doesn`t work when I use my Kinect2 ,the camera window displays "Waiting for Images".
As chwimmer said above ,before rosrun ,I have run "roslaunch kinect2_bridge kinect2_bridge.launch" ,but it doesn't work. If I still do not start driver of the Kinect2,than how should I do ? Please give me a favor? Thank you!
from orb_slam2.
when you start
roslaunch kinect2_bridge kinect2_bridge.launch
the topics here described are published. When you didn't do any remapping or change in the code ORBSLAM2 expects images at the topics:
/camera/rgb/image_raw
and camera/depth_registered/image_raw
So the published topics and the subscribed topics dont correspond to each other. Thats why you got the
"Waiting for Images" state.
from orb_slam2.
@UThinkD Hi, I'm meet the same problem!How did you change the topic from"/camera/rgb/image_raw and camera/depth_registered/image_raw" to the topics of kinect2? Please give me a favor?
from orb_slam2.
from orb_slam2.
@UThinkD Thanks very much .I have solved this problem by your advice.And the introduce of ROS topic is :http://wiki.ros.org/cn/ROS/Tutorials/UnderstandingTopics
from orb_slam2.
@poine did you make the patch? I also would like to see the published topics
from orb_slam2.
Hey everyone,
I am using Xtion PRO LIVE with the ORB-SLAM2. My ORB-SLAM2 does not work with the Xtion PRO LIVE. I used OpenNI2 to install Xtion PRO LIVE. My camera work with ROS, but it cannot work with ORB-SLAM2. I also tested my camera with libfreenect-dev , but it did not work with ORB-SLAM2.
I faced the following error:
[ INFO] [1514967208.178975139]: No devices connected.... waiting for devices to be connected
please guide me.
