Estimate people pose and hand pose in 2d. Please refer to original paper.

In order to use this feature, you need to install chainer. To install chainer with GPU support, please refer to this page.

Subscribing Topic

  • ~input (sensor_msgs/Image)

    Input image.

  • ~input/depth (sensor_msgs/Image)

    Input depth image.

  • ~input/info (sensor_msgs/CameraInfo)

Publishing Topic

  • ~output (sensor_msgs/Image)

    Detected people pose image.

  • ~pose (jsk_recognition_msgs/PeoplePoseArray)

    If with_depth is true, publish 3D joint position.

    If with_depth is false, publish 2D joint position in image.

  • ~pose2d (jsk_recognition_msgs/PeoplePoseArray)

    If with_depth is true, publish 2D joint position.

  • ~skeleton (jsk_recognition_msgs/HumanSkeletonArray)

    If with_depth is true, publish 3D human skeletons.

    Rviz visualization is available in jsk-ros-pkg/jsk_visualization #740.
