Optical tracking is a technology that uses cameras and sensors to monitor the movement of objects in real-time. It captures images and analyzes them to determine the position and orientation of the tracked object. This method is commonly used in various fields, including virtual reality, augmented reality, and motion capture for films and video games. The system typically relies on specific markers or patterns placed on the object being tracked. By comparing the captured images to a reference, the system can accurately calculate the object's movement. Optical tracking is valued for its precision and ability to provide detailed data about motion dynamics.
