FE108

FE108数据集由基于DAVIS346事件的摄像机捕获，该摄像机配备了346x260像素动态视觉传感器 (DVS) 和有源像素传感器 (APS)。它可以同时提供场景的事件和对齐的灰度图像。移动目标的地面真实边界框由Vicon运动捕获系统提供，该系统以高采样率 (高达330Hz) 和亚毫米精度捕获运动。在捕获过程中，我们将APS的帧速率固定为20/40 FPS，将Vicon的采样率固定为240Hz，这也是捕获的APS帧和累积事件的注释频率。FE108在

The FE108 dataset is captured using a DAVIS346 event-based camera, which is equipped with a 346×260 pixel dynamic vision sensor (DVS) and an active pixel sensor (APS). It can simultaneously provide both event streams and aligned grayscale images of the scene. The ground-truth bounding boxes for moving targets are provided by the Vicon motion capture system, which captures motion at a high sampling rate (up to 330 Hz) with sub-millimeter accuracy. During the data capture process, we fixed the APS frame rate to 20/40 FPS and the Vicon sampling rate to 240 Hz, which also serves as the annotation frequency for the captured APS frames and accumulated events. The FE108 dataset features the following key attributes:
1. High-quality annotations: The Vicon system can provide 3D positions with sub-millimeter precision.
2. Diverse target categories: Spans 21 classes including animals, vehicles and daily necessities.
3. Diverse event rates: The average event rate ranges from 0 to 3800 Ev/ms.
4. Real-world challenging scenarios: Involves low-light conditions, high dynamic range, fast motion, motion blur and other realistic challenges.
