# Autonomous landing of a UAV
ROS packages developed for the autonomous landing of a UAV on a stationary platform.
## Description
The autonomous landing system has been tested in Simulation with Gazebo and with a modified DJI F450 with an onboard computer. The workflow of the system is a simulated environment is as follows. The system is launched in Gazebo and communicated with the Firmware of PX4. Then, the vehicle takeoff from the ground and moves to a position where the landing platform is visible. The detection module starts working and with a feature-based detector and a Kalman Filter, the landing pad is tracking thoroughly. Once the first estimation of the landing platform is made, the landing controller begins to work and moves the vehicle towards the center of the platform while it is descending. Finally, the vehicle lands and ends its mission.
This system can be used in more complex tasks where the landing phase wants to be automated. Precision agriculture, Patrolling and building inspection are just few examples where a system like this might be used to land the vehicle.
The following diagram illustrates the general workflow of the system. First the homography matrix is computed between the current image frame and the predefined template, using a feature-based detector. Then, the homography matrix is used to compute the corners and the centroid of the object. These points are then passed to a Kalman filter estimation module. Finally, the Kalman filter estimations are used to track the template in the image frame, and passed as input for a set of three PID-based controllers that perform the safe landing of the vehicle
There are three main packages that compose this project, these are:
1. mavros_off_board
2. object_detector
3. drone_controller
In the package *mavros_off_board* are the launch files, world file, description files (urdf, xacro, sdf) and basic scripts to control the aircraft. The package *object_detector* is the detection and tracking (Kalman Filter) pipeline of the system, this module allows the tracking of a landing template. Finally, *drone_controller* has the proportional and PID controllers developed to land the vehicle based on the estimations made with the *object_detector* package.
