Dataset of real-world and Unreal Engine captured images of a Landing pad with a KIOS sticker. The airsim dataset contains images from three different backgrounds as well as augmented images generated from these backgrounds. The annotations are available only in YOLO format. Environment 1 / Augmented : 117 images / 425 images Environment 2 / Augmented : 163 images / 618 images Environment 3 / Augmented: 175 images / 647 images Real video: 422 images Dataset used in: Soteriou, C., Kyrkou, C., Kolios, P.S.
