OpenPose - Get Direction Node

This custom node for ComfyUI analyzes OpenPose keypoints to determine if a person in an image is facing forward, showing their left side, or their right side.

Features

• Robust direction detection using body (shoulders, nose) and face keypoints (if available)
• Returns both a string ("forward", "left", "right") and an integer code (0 for forward, 1 for left, 2 for right)
• Designed for use with OpenPose COCO-format keypoints (e.g., dw-ll_ucoco_384.onnx)

How It Works

• The node examines the position of the nose relative to the shoulders and, if available, the symmetry of face keypoints (eyes and mouth corners).
• If the nose is centered between the shoulders and the face is symmetric, the person is considered to be facing forward.
• If the nose is offset to one side and the face is not symmetric, the node determines if the person is showing their left or right side.

Output

• direction (string): One of "forward", "left", or "right"
• direction_code (int):
  • 0 = forward
  • 1 = left
  • 2 = right

Example Results

Forward

Left

Right

Usage

1. Add the node to your ComfyUI workflow.
2. Connect the output of your OpenPose node (with COCO-format keypoints) to the pose_kps input of this node.
3. The node will output the direction as both a string and an integer code.

Test Workflow

A sample workflow is provided to test the node:

• Test Detection Workflow

You can load this workflow in ComfyUI to see the node in action with example images and keypoints.
