论文摘要
活动摄像头是一种与传统相机不同的新型传感器。每个像素都是通过事件异步触发的。触发事件是像素上辐照的亮度的变化。如果增量或减少高于一定阈值，则该事件是输出的。与传统摄像机相比，事件摄像机具有高时间分辨率，低潜伏期，高动态范围，低带宽和低功耗的优势。我们在模拟的空间照明环境中进行了一系列观察实验。实验结果表明，事件摄像机可以全面发挥太空情境意识中的上述优势。本文首先介绍事件摄像机的基本原理，然后分析其优点和缺点，然后介绍观察实验并分析实验结果，最后给出了基于事件摄像机的空间情境意识的工作流程。
Event camera is a new type of sensor that is different from traditional cameras. Each pixel is triggered asynchronously by an event. The trigger event is the change of the brightness irradiated on the pixel. If the increment or decrement is higher than a certain threshold, the event is output. Compared with traditional cameras, event cameras have the advantages of high temporal resolution, low latency, high dynamic range, low bandwidth and low power consumption. We carried out a series of observation experiments in a simulated space lighting environment. The experimental results show that the event camera can give full play to the above advantages in space situational awareness. This article first introduces the basic principles of the event camera, then analyzes its advantages and disadvantages, then introduces the observation experiment and analyzes the experimental results, and finally, a workflow of space situational awareness based on event cameras is given.
