The development of rotary wing UAV landing control software

Unmanned Aerial Vehicles (UAVs), are air aircraft that can fly autonomously without human control or that can be controlled by a ground station. In parallel with the technological developments of the present day, it has been observed that the use of UAVs is also greatly increased. In this context, new working areas were needed together with the widespread use of UAVs. As a result of the researches, the autonomous control works were seen to become the foreground. Within the scope of this study, an autonomous landing system based on image processing has been realized for UAVs. The images taken with the help of a wide angle and high-resolution camera located at the bottom of the UAV are subjected to image processing techniques on the Linux based operating system to determine the landing station. The designed landing station is a circle with a "H" in the middle. The circle and letter "H" on the landing station are selected in red color. After determining landing station, the altitude of UAV is gradually decreased and the image acquisition and measurement process are repeated until it reaches a desired position. When arriving at the desired position, the UAV performs descent by stopping motors.
