Event-based Shock Wave Measurement
Analysis
This paper introduces a novel method for measuring shock wave motion using event cameras, addressing challenges in high-speed and unstable environments. The use of event cameras allows for high spatiotemporal resolution, enabling detailed analysis of shock wave behavior. The paper's strength lies in its innovative approach to data processing, including polar coordinate encoding, ROI extraction, and iterative slope analysis. The comparison with pressure sensors and empirical formulas validates the accuracy of the proposed method.
