Development status and trend of event-based vision sensor
Event-based vision sensor is a new type of bionic vision sensor, which is more similar to the working mechanism of human eye, and makes it widely concerned. Different from the working mechanism and output mode of traditional frame-based cameras, the pixels of event-based vision sensors can individually detect logarithmic change of light intensity, and output event information including location, time, and polarity when the amount of change exceeds a certain threshold. The event-based vision sensor has the advantages of low latency, high dynamic range, and low power consumption. Its unique output mode and working characteristics make it especially suitable for occasions with high-speed movement, large changes in lighting conditions, or low energy consumption. This article introduces the development history, classification, working principle, advantages and disadvantages of event-based cameras, as well as their applications in the fields of rapid motion tracking and monitoring, target recognition, simultaneous localization and mapping(SLAM) in recent years. Finally, it summarizes the challenges that the event-based camera still exists in different application fields, and looks forward to its future development. The wide application of event-based cameras can provide new solutions for high-speed motion and high dynamic range occasions where traditional cameras are still tricky. With continuous updates and development in the future, it will be able to play a role in more complex application scenarios.
