A 640×480 Dynamic Vision Sensor with a 9μm Pixel and 300Meps Address-Event Representation

📋 论文概要

该论文提出了一种VGA分辨率的动态视觉传感器（DVS），像素尺寸为9μm，采用数字与模拟混合实现。解决了现有DVS空间分辨率低、事件率不足的问题，实现了640×480分辨率和300Meps的事件输出速率。

💡 主要创新点

• 实现了VGA（640×480）高分辨率DVS，像素尺寸仅9μm。
• 通过数字和模拟混合设计达到300Meps的事件率，远高于此前文献的50Meps。

DVS systems in the literature try to increase spatial resolution up to QVGA [1-2] and data rates up to 50 million events per second (Meps) (self-acknowledged) [3], but they are still inadequate for high-performance applications such as gesture recognition, drones, automotive, etc. Moreover, the smallest reported pixel of 18.5μm is too large for economical mass production [3]. This paper reports a 640×480 VGAresolution DVS system with a 9μm pixel pitch supporting a data rate of 300Meps for sufficient event transfer in spite of higher resolution. Maintaining acceptable
