Error running on Ubuntu 20.04 with RealSense about ros_openpose HOT 3 CLOSED

Hello @ravijo,

Sorry for the delay.

Since I'm using ROS Noetic and therefore Python3, I just had to call the scripts echo.py and visualizer.py with Python3 instead of Python2 by editing the first line of the scripts to #!/usr/bin/env python3 and it's working fine right now.

Thank's a lot!

Regards,
Fabian

Hello @SM30000

I am glad that you find it useful.

Yeah, you are right. The visualizer.py and echo.py are somehow unable to work as expected.

After OpenPose v1.6, I couldn't check the code with newer versions so far. But as you said, the OpenPose standalone works without any issue, so together we need to find out the culprit. Therefore, I am looking for your kind support in this matter.

Luckily, it is possible to disable visualizer.py and echo.py by command line. Can you please execute the following command-

roslaunch ros_openpose run.launch camera:=realsense skeleton:=false print:=false

Furthermore, I would like you to manually invoke realsenese camera to see if it is all right. To do so, kindly print the color, depth and camera info topics as suggested in the instructions below:

Color Topic

rostopic echo /camera/color/image_raw

Depth Topic

rostopic echo /camera/aligned_depth_to_color/image_raw

Camera Info. Topic

rostopic echo /camera/color/camera_info

ros_openpose uses these 3 information from the realsense camera. It passes the color image to OpenPose and then uses depth + camera info to compute cartesian coordinates in 3 dimensions.

Therefore, it is necessary above 3 rostopic echo command must print something in the terminal. Please use Ctrl + C to stop these echo commands.

Let me know the outcome, please.
