We present a vision sensor chip designed to detect multiple transient objects - objects that either move or change in light intensity - and output their locations using address-event representation. The sensor uses a novel onset detector to detect transient objects and a dynamically-wired winner-takes-all circuit to group pixels and select the brightest pixel in each object. This paper describes the circuits and also presents measurements that characterize the performance of the sensor chip.
我们提出了一种视觉传感器芯片的设计,用于检测多个瞬态物体 - 即移动或光强度变化的物体 - 并使用地址事件表示法输出它们的位置。该传感器使用新颖的起始检测器来检测瞬态物体,并使用动态布线的胜者全取电路来对像素进行分组,并选择每个物体中最亮的像素。本文描述了这些电路,并给出了用于表征传感器芯片性能的测量结果。
