Also, if you had a build space, you should delete it as it still refers to OpenCV 3.1 and it got bumped to 3.2. yes, my

How do you get to that?

[U V W]^T = P * [X Y Z 1]^T   (X=xyz.x, Y=xyz.y ...)

with P something like:

[[ fx 0 0 Tx]
 [ 0 fy 0 Ty]
 [ 0 0  1 0]]

That gives: u = U/W + cx which is what we have in the code no?

Thx @dirk-thomas !

Have you tried with any other package ? (unrelated to OpenCV)

It's probably due to your physical setup, please provide some description / a picture of the setup. There might be a big disparity between your images, usually those give such black areas.

You can use rosparam. There is an example given here: http://wiki.ros.org/roslaunch/XML/ros...

Hi all, thank you for sharing the data. A fix was merged upstream in 1.3.8: it just reached shadow fixed so please test. The fix centers the scan before sending them to gmapping, whether they're slightly / completely off-centered or even upside-down.

please guys, don't try to find workarounds: report the bug at least; better, help fixing it :)

can anybody please send me a failing rosbag ? My personal email is https://github.com/ros-perception/sla...

That is exactly what tf2 is doing with the transform function of the BufferInterface: http://docs.ros.org/jade/api/tf2_ros/...

tf2_sensor_msgs is just a package that enables tf2 to transform sensor_msgs (including PointCloud2)

what do you define as a "visual module language editor" ? what would be an example out there ?

The tutorials have been totally revamped here: http://wiki.ros.org/nao/Tutorials

Please update to the latest code that should have handled those issues.

only the joint states is in C++ for now

well, it's a matter of debugging: what does "echo $AL_DIR" say ? The variable is used here: https://github.com/ros-naoqi/naoqi_br... Is it set there to the right value ? (message(STATUS "$ENV{AL_DIR}/include ${NAOqi_INCLUDE_HINTS}")

Did you follow those instructions ? http://wiki.ros.org/nao/Tutorials/Ins...

export_header is unfortunately a qibuild only macro. Are you on a 64 bit machine ? Which part of the tutorial exactly ? Do you want to do C++ on your machine or on the robot ? Also, we just announced an official C++ bridge: https://groups.google.com/forum/#!top...

Which tutorial are you mentioning ? Why do you compile in 32 ? Are you in a VM or are you cross-compiling ? Do you need the C++ bridge ? It provides the same functionality as the Python one. The right method is to set NAOqi_DIR as mentioned in the Cmake comment, how do you set it ?

The leg_right problem is clearly a bug, you should file a bug report. Otherwise, did you follow the tutorials https://github.com/ros-naoqi/nao_move... and clicked on the approximate IK box in RViz ? NAO does not have 6 or more dof so this is required.

you can use PyKDL as shown here: https://github.com/ros-perception/cal...

All you need is here: http://docs.ros.org/diamondback/api/k...

The fix was pushed upstream indeed

hey, are you using a real NAO ? you are just launching a local NAOqi right ? there is no audio device locally.

that's probably the tutorial you are looking for: http://wiki.ros.org/rviz/Tutorials/Li...

And btw, the code just changed to give a normal error code. That should appear in the next release.

Actually, I just found that you can get old NAOqi's versions here: http://robocup.bowdoin.edu/public/sof...

Rather than to fix the build issue I will be using http://wiki.ros.org/nao/Installation/...

Why Fuerte ? it is not supported anymore. http://wiki.ros.org/nao/Installation/compileFromVirtualNao should be better no ?

you have 3 imshow, it's one of those.

You are displaying an empty image. Just add a test: if it is empty, do not display it.

use bridge.imgmsg_to_cv2 and drop cv. support is a first advice What is the error message ? Please also print the shape of the numpy array.

This was an upstream bug in the instructions as mentioned in the comments. It was fixed. Please up that answer so that we can close it. Thx.

@joq, that was basically a bug in the instructions that got fixed. What do you mean by "check" ? (no real answer appeared). Thx !

The answer is in the output: -- gtest not found, C++ tests can not be built. Please install the gtest headers globally in your system to enable gtests Is gtest really installed there ? (is it part of your workspace or emerged ?)

Call the same function but use http://simplecv.org/docs/SimpleCV.htm... on your simpleCV image. E.g. :

cv2_to_imgmsg(simple_cv_image.getNumpyCv2(), encoding="passthrough")

And the other way around from an Image msg to a Simple CV image:

Image(imgmsg_to_cv2(image_msg, encoding="passthrough"), cv2image=True)

what do you launch from the command line ? Do you set NAO_IP and roslaunch the nao_camera.launch ?

As mentioned by AHornung, your problem is that you need to do:

export PYTHONPATH=~/nao/tools/pynaoqi-python-2.7-naoqi-1.14-linux64:$PYTHONPATH

(and not LD_LIBRARY_PATH). The error you get (though totally unexplicit) is typical from not finding naoqi on your PYTHONPATH

what version of the robot do you have ? Aldebaran does not support such an old NAOqi anymore. You can't upgrade to 1.14 ?
