Victor97 commented 5 years ago

Hello,do you know why is the fps is so low，i think it is about 15fps. How can i increase the frame rate?

Which GPU are you using? The FPS may be low because of your gpu. You can check your GPU performance here: https://docs.google.com/spreadsheets/d/1-DynFGvoScvfWDA1P4jDInCkbD4lg0IKOYbXgEq0sK0/edit#gid=0 When you run the OpenPose example without using openpose_ros, what fps do you get?

Another issue might be that 15fps is your camera fps. I designed this ROS wrapper to only run as fast as your camera's fps in order to not waste GPU resources reprocessing the same image. So you should check your camera's fps using rostopic hz as well.
