II. How does pose estimation work?
Overview of the process
Pose Estimation
Pose estimation involves using sensors and cameras to capture data about a person’s position and orientation in 2D or 3D space.
Pose Classification
The pose estimation data is then processed using algorithms and machine learning techniques to determine the pose. The specific approach and techniques used will depend on the application and desired level of accuracy.
Key components and technologies involved
Sensors and cameras:
These are used to capture data about the object or person’s position and orientation. This can include optical sensors, such as cameras and depth sensors, as well as other types of sensors, such as inertial measurement units (IMUs).
Feature Detection and Tracking
Once the data is captured, the next step is to identify and track specific features on the user’s body. Tools such as MediaPipe, Google ML Kit and Apple ML Kit
Pose algorithms and machine learning:
Once the data has been captured and the relevant features have been identified, algorithms and machine learning techniques are used to determine the pose. This can involve solving geometric problems, using supervised or unsupervised learning, or a combination of these approaches.
