This survey provides a comprehensive overview of event-based vision, covering the fundamental principles of event cameras, available sensor technologies, and the diverse algorithms developed to process their unique asynchronous data. It highlights how these sensors offer microsecond temporal resolution, high dynamic range, and low latency, enabling robust perception in scenarios challenging for conventional cameras.
Key insights
- Event cameras exhibit microsecond temporal resolution, 140 dB dynamic range, sub-millisecond latency, and milliwatt-level power consumption, making them superior to conventional cameras in challenging conditions.
- The asynchronous, sparse nature of event data necessitates novel processing paradigms, including diverse event representations (e.g., time surfaces, voxel grids) and tailored algorithms like asynchronous filters and adapted deep learning architectures.
- A strong synergy exists between event cameras and neuromorphic processors, which are designed for parallel, asynchronous computation, enabling ultra-low-power, low-latency perception systems.
