Installation

Openpose

See Openpose.

After building openpose, set the environment variable OPENPOSE_HOME.

$ export OPENPOSE_HOME='{path/to/your/openpose/home}'

Packages

$ sudo apt-get install ros-indigo-image-common ros-indigo-vision-opencv ros-indigo-video-stream-opencv ros-indigo-image-view

$ cd src
$ git clone https://github.com/Seri-Lee/ros-openpose.git
$ cd ..
$ catkin_make

Message

Parameter

• resolution(string, default: 640x480) : input image resolution
• net_resolution(string, default: 640x480) : network resolution
• num_gpu(int, default: -1) : number of gpus to use. -1 indiciates 'all'.
• num_gpu_start(int, default: 0) : first index of gpu to use.
• model_pose(string, default: COCO) : pose estimation model name provided by openpose.
• no_display(bool, default: false) : if true, it will launch opencv image view to show realtime estimation.
• camera(string, default: /camera/image)
• result_image_topic(string, default: '') : if provided, it will broadcast image with estimated pose.

Broadcast

• /openpose/pose : Msg
  • Persons
    • BodyPartDetection

BodyParts are stored as indexed Nose = 0 Neck = 1 RShoulder = 2 RElbow = 3 RWrist = 4 LShoulder = 5 LElbow = 6 LWrist = 7 RHip = 8 RKnee = 9 RAnkle = 10 LHip = 11 LKnee = 12 LAnkle = 13 REye = 14 LEye = 15 REar = 16 LEar = 17
