Motion Track Drawing for Variable Camera Angles

The patent introduces background pixel points as intermediary reference objects that remain relatively stable across frames. By calculating motion vectors of these background points and using them to compensate for camera movement, the system creates a reference framework that allows accurate motion tracking even when camera angles change dynamically.

The patent replaces traditional mechanical or manual tracking methods with computational image processing. By using optical flow algorithms to calculate motion vectors and compensating for camera movement through digital image registration, the system achieves accurate motion track visualization without requiring fixed camera mounting or manual intervention.

The patent segments the video processing into distinct functional modules: background pixel point identification, motion vector calculation, camera movement compensation, and motion track drawing. This segmentation allows the complex task of motion track visualization to be broken down into manageable processing steps that can be executed efficiently in real-time video playback.

The patent creates a virtual copy of the motion track information by calculating and drawing the trajectory of motion elements based on their position in multiple consecutive frames. This copied motion information is then overlaid on the original video, providing additional visual data without replacing the original content.
