Area of Science:

Robotics
Computer Vision
Biomimetic Systems

Background:

Neuromorphic vision sensors (event cameras) offer low reaction times crucial for high-dynamic robotics.
Event cameras struggle with capturing object edges parallel to motion, a significant limitation.
Human vision uses microsaccades to maintain texture stability and prevent perceptual fading.

Purpose of the Study:

To design an event-based perception system that maintains low reaction time and stable texture.
To address the intrinsic limitations of event cameras in capturing motion-parallel edges.
To enhance robotic perception capabilities using a biomimetic approach.

Main Methods:

Developed an artificial microsaccade-enhanced event camera (AMI-EV) by integrating a rotating wedge prism with an event camera.
Utilized geometrical optics for algorithmic compensation of rotational motion.
Implemented a hardware-software integrated system for enhanced visual perception.

Main Results:

The AMI-EV system successfully maintains stable texture and high informational output independent of external motion.
Benchmark comparisons showed superior data quality from AMI-EV compared to standard and conventional event cameras.
The system demonstrated effectiveness in scenarios where other cameras failed.

Conclusions:

The artificial microsaccade-enhanced event camera (AMI-EV) effectively overcomes event camera limitations.
This novel system significantly improves data quality and stability for robotic vision tasks.
AMI-EV shows great potential for advancing both low-level and high-level robotic perception.
