The vision-based system is a crucial component of unmanned aerial vehicle (UAV) autonomous flying and is frequently regarded as a difficult phase to accomplish. Most UAV accidents happen while landing or due to obstacles in the path. Hence, it is considered as one of the most important to think about the auto landing of UAVs to reduce accidents. Some technologies, like GPS, frequently don’t function indoors or in places where GPS transmissions aren’t allowed. They can land up to a few meters but lack accuracy. A system that operates in such circumstances is required to overcome this and be far more suitable. Cameras are used to offer much information about their surroundings and may be helpful in certain circumstances. A vision-based system’s accuracy can be as low as a few centimeters and better than GPS-based location estimation. This work involves designing a vision-based landing system that can recognize a marker by providing the bounding box around it. Typically, the H mark is employed in helicopter landing pads for vision-based landing systems. Here, the position is identified using the YOLOv5 algorithm.

The algorithm is tested to locate the marker at any orientation and scale. Thus, YOLOv5 identifies the marker at any distance, orientation, or size in the given data set and performs better than SVM-based approach. This could be further used to find the distance on the ground from the UAV center that aids in auto landing.
