In this blog we will show you how to label actions in drone videos, as shown in the video below: https://www.youtube.com/watch?v=y05iJ0vMnuI We use Microsoft VoTT as our labeling tool. The summary of labeling steps are listed as follows: ' Install Microsoft VoTT v2.1.0 ( link ) or NTUT VoTT v0.0.5 ( Windows ) Add security token to VoTT  Name : NTUTDrone Token Key : qITjd1Rj6hFqC7uB0OGxPKYVxIFSdcMrprQAMS5rEhc= Download Drone videos ( DroneVideos ) and labeling projects ( VoTT Projects ) Create two folders: C:\Drone_Target\ and C:\Drone_Source\ Put VoTT project to C:\Drone_Target\ Put drone video to C:\Drone_Source\ (Make sure ONLY project videos in this folder) Open VoTT project file ( C:\Drone_Target\Drone_001.vott ) Label and check actions ( action_lists ) ( Check Labels ) Let's see the detailed steps now. 1. Install Microsoft VoTT Download VoTT from GitHub ( https://github.com/microsoft/VoTT/releases ). Install and open VoTT 2. Add securit...

ArduPilot Software-In-The-Loop (SITL), MavLink, and AirSim

In this article, I would like to share my experience of setting up ArduPilot SITL running with AirSim using Cygwin on Windows. The result is shown in the picture below. I hope this post can be complementary to the original AirSim SITL tutorial Using SITL with AirSim . First of all, let's see the architecture of AirSim SITL: The red block represents SITL, which connects to physics simulator (blue block), which is AirSim, and a Ground Control System (GCS), which is MAVProxy in our case. So we will run three programs that communicates with each other through TCP/IP.  Now we are ready to run the simulation. The major steps are listed below: Git clone ArduPilot and build it under Cygwin. You can follow ArduPilot tutorial ( link ) or see my summary at the section ( Run SITL using Cygwin ). Install Unreal and git clone AirSim and build it, OR  download pre-built AirSim precompiled binaries ( link ) Edit “Documents\AirSim\settings.json”, note the default folder is you...
