Paragraph starter
The development of high-speed multi-camera systems, such as those for automotive applications, necessitates rigorous attention to temporal synchronization. Research by Azzopardi et al. (2010) demonstrated a tri-vision system achieving synchronization errors below 100 picoseconds, highlighting the feasibility of precise temporal alignment even at high frame rates (up to 750 Hz with ROI). This level of synchronization is critical for applications requiring accurate capture of rapid events, ensuring that data from different viewpoints is temporally coherent for subsequent analysis or system response.
