Yolo Pose Estimation and Skeleton

Introduction

Make a pose estimator and use it to make a moving skeleton.

Use Yolo from Ultralytics.

• Python 3.7+
• Yolo v11
• A CUDA-enabled GPU (optional but recommended for faster inference).

pip install ultralytics opencv-python numpy

Yolo

There are 17 keypoints. YOLOv11’s pose model outputs:

• (x, y) coordinates for each keypoint and
• confidence scores indicating the model’s certainty in each keypoint’s position.
