一种用于事件相机感知的反光干扰抑制装置及方法
By employing a hardware-software co-processing method to suppress reflective interference, a stroboscopic emission module and a bandpass filter are used to separate reflective interference from target surface features in an event camera. This solves the separation problem of the event camera in highly reflective surface scenarios, achieving high-precision feature preservation and fast response.

AI Technical Summary
Existing technologies struggle to effectively separate reflective interference from target surface feature signals in event camera perception, especially in highly reflective surface scenarios, which affects the accuracy and robustness of 3D reconstruction and pose estimation.
A hardware and software co-processing approach is adopted, which uses a stroboscopic light emission module to actively modulate the target surface in time, and introduces a bandpass filter and a processing terminal into the event camera for algorithm processing. The time gating function and spatial mask are used to separate the reflective interference from the target surface feature signal.
It significantly suppresses reflective interference, preserves target surface feature information, maintains the high response speed and low latency of the event camera, and improves perception accuracy and stability, making it suitable for two-dimensional and three-dimensional perception tasks.
