Head pose estimation
Real time human head pose estimation using TensorFlow and OpenCV.
These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.
The code was tested on Ubuntu 20.04.
This repository already provided a pre-trained model for facial landmarks detection. Just git clone then you are good to go.
# From your favorite development directory: git clone https://github.com/yinguobing/head-pose-estimation.git
A video file or a webcam index should be assigned through arguments. If no source provided, the built in webcam will be used by default.
With video file
For any video format that OpenCV supports (
python3 estimate_head_pose.py --video /path/to/video.mp4
The webcam index should be provided:
python3 estimate_head_pose.py --cam 0
How it works
There are three major steps:
Face detection. A face detector is introduced to provide a face bounding box containing a human face. Then the face box is expanded and transformed to a square to suit the needs of later steps.
Facial landmark detection. A pre-trained deep learning model take the face image as input and output 68 facial landmarks.
Pose estimation. After getting 68 facial landmarks, the pose could be calculated by a mutual PnP algorithm.
The marks are detected frame by frame that makes the pose unstable. A Kalman filter is used to solve this problem, you can draw the original pose to observe the difference.
