Hi Ravi
The problem is fixed
Thank you very much for your valuable help
from ros_openpose.
After installation of ros-visualization-msgs
sudo apt-get install -y ros-visualization-msgs
In rviz Human Skeleton, Status: Error:
Uninitialized quaternion, assuming identity.
scale.y and scale.z of LINE_LIST or LINE_STRIP are ignored.
Points should not be empty for specified marker type.
At least two points are required for a LINE_STRIP marker.
In rviz the whole person is shown in green
output rostopic echo /frame

from ros_openpose.
@OsArkoses: The output given by you in the above two messages is not matching with each other. In the first message, I can see that parameters leftHandParts
and rightHandParts
are empty list. In the second message, I can see that the parameter leftHandParts
contains 21 points, which is expected (correct).
-
First of all, I suspect that your ROS installation is broken (or you have not installed a complete ROS package. I mostly install the full version, i.e.,
ros-${DISTRO}-desktop-full
. Therefore can you please make sure you have all the packages installed?(To confirm the above point, you can simply try using my another ROS package which uses the almost same method for visualization. You don't need to install dependency kinect_anywhere this time. Just clone/download the repository and make python scripts executables. Finally run
roslaunch rviz_skeleton_visualization visualization.launch
. If you see a static human visualization inside RVIZ then you don't need to install extra ROS packages.) -
Secondly, in the first message, you reported that the error is at line 169, which is a bit surprising. In the latest version, the line
leftHandPart = person.leftHandParts[point_id]
is at number 165. Can you please pull the latest source code from GitHub and try again? -
The error about
id_text_offset
reported by you via email was a bug which is fixed in the latest code. Please use the latest code from GitHub and try again. -
From the screenshot you shared with me, it seems that the parameter
skeleton_line_width
needs to be set to a much lower value. Please open run_kinect.launch file and change the value0.01
to a much lower value such as0.005
and try again. -
Finally, please unset the variable
skeleton_hands
if you don't want to see fingers inside the RVIZ by executing the following command-
roslaunch ros_openpose run.launch skeleton_hands:=false
Let me know if the problem persists.

Hello Ravi
- Yes, I have the desktop-full installation
- I modificated the file, I wanted to print the content
- Thanks, I did the changes.
- This was my problem, I made the changes and now it's going well.
- Thanks.
I have a question, Is it normal for the skeleton to be distorted at the time of viewing in Rviz? incorrect lines appear. In the openPose by default if the points are displayed correctly.

Hi @OsArkoses
Glad that you made it work!
Is it normal for the skeleton to be distorted at the time of viewing in Rviz? incorrect lines appear. In the openPose by default if the points are displayed correctly.
-
3D point calculation highly depends on the depth values received by the camera. I believe that the depth information is fluctuating, which is causing the distortion. You can see that the point cloud inside RVIZ is swinging too. If required, you can preprocess 3D points by applying the filtering process to reduce the fluctuation.
-
You can reduce the
lifetime
of the skeleton lines. The marker property 'lifetime' defines how long the object should last before being automatically deleted. 0 means forever. Please set it to a lower value (less than 1) here. -
If you see that the skeleton is not overlapping with your body inside the point cloud, then you must calibrate (intrinsic calibration) your camera. Please note that I haven't considered camera distortion while computing 3D points from pixels.
-
Furthermore, the fluctuation may not be easily visible in the image (2D) because of the small pixel values, but in 3D, it gets converted into real values (shown in meters).
Let me know if this helps.

Hi @OsArkoses,
Can you please confirm if the problem is fixed? I will close this thread after your acknowledgment.
