Relative Motion Analysis using Rotating Axes

Relative Motion Analysis using Rotating Axes

Consider a component AB undergoing a linear motion. Along with a linear motion, point B also rotates around point A. To comprehend this complex movement, position vectors for both points A and B are established using a stationary reference frame.
However, to express the relative position of point B relative to point A, an additional frame of reference, denoted as x'y', is necessary. This additional frame not only translates but also rotates relative to the fixed frame, making it...

Background:

Crowded scene surveillance benefits from integrating egocentric (wearable) and top-view (drone) cameras.
Tracking multiple individuals across these complementary views presents a significant challenge.

Purpose of the Study:

To develop a robust method for associating and tracking multiple subjects across egocentric and top-view videos.
To address the limitations of traditional tracking methods in handling cross-view subject identification.

Main Methods:

Formulated the problem as a constrained mixed integer programming task.
Proposed a novel spatial distribution-based approach for reliable cross-view subject association.
Developed a new dataset to benchmark this challenging surveillance task.

Main Results:

The spatial distribution method effectively measures subject similarity across complementary views.
Experimental results demonstrate the superiority of the proposed approach over existing methods.
The new dataset facilitates reproducible research in multi-view, multi-person tracking.

Conclusions:

Combining egocentric and top-view cameras significantly enhances crowded scene surveillance.
The proposed spatial distribution method offers a reliable solution for cross-view subject association and tracking.
This work provides a valuable benchmark and methodology for future research in collaborative multi-view surveillance.
