Oct 5, 2018 · Event cameras are revolutionary sensors that work radically differently from standard cameras. It leverages two consecutive RGB images, converted to grayscale, to compute the 'past events' that would have occurred based on changes in log luminance. An event camera is a special vision sensor that measures changes in logarithmic brightness and only reports 'events'. Press F1 key to see keyboard shortcuts for turning on/off any or all views. 2. An event camera is a specialized sensor that measures changes in logarithmic brightness and reports 'events' based on significant changes. then turn to the works on simulation of an event camera. Cosys-AirSim provides a Python-based event camera simulator, aimed at performance and ability to run in real-time along with the sim. Computer Vision Mode# Camera names are same as in multirotor. The camera views that are shown on screen are the camera views you can fetch via the simGetImages API. shape # The resolution of the image # We ignore the 2D nature of the problem as it is not relevant here AirSim provides a Python-based event camera simulator, aimed at performance and ability to run in real-time along with the sim. shape) self. See Image APIs for description of various available views. Mar 28, 2025 · Key Features of Event Cameras. 2. event_rl contains code to take pretrained eVAE representations and train RL policies to perform obstacle avoidance in AirSim. Mar 29, 2025 · Understanding Event Cameras. The events are transmitted as a byte stream in the following then turn to the works on simulation of an event camera. Instead of capturing intensity images at a fixed rate, event cameras measure changes of intensity Feb 9, 2025 · To implement optical flow in AirSim's event camera simulator, it is essential to understand the underlying principles of event cameras and how they differ from traditional RGB cameras. High Temporal Resolution: Event cameras can achieve temporal resolutions in the microsecond range, allowing them to capture rapid movements without motion blur. Mar 8, 2021 · We recently released a new feature that allows “simulating” the output of an event camera inside AirSim, which we use to generate event data from a drone flying around in an obstacle field, and we first train the event-VAE on this data composed of event observations of obstacles. Nov 13, 2023 · 本篇博客我们重点记录利用AirSim仿真环境进行多传感器数据(Camera、LiDAR、IMU)采集的完整流程和注意事项，方便以后查阅。在之前的这篇笔记中我们初步介绍了利用AirSim进行双目相机、IMU、LiDAR等多模态数据的采集。但如果从SLAM的角度，其中其实有一些小问题。.
