To detect UAVs in real-time, computer vision and deep learning approaches are
developing areas of research. There have been concerns raised regarding the
possible hazards and misuse of employing unmanned aerial vehicles (UAVs) in
many applications. These include potential privacy violations, safety-related
issues, and security threats. Vision-based detection systems often comprise a
combination of hardware components such as cameras and software components. In
this work, the performance of recent and popular vision-based object detection
techniques is investigated for the task of UAV detection under challenging
conditions such as complex backgrounds, varying UAV sizes, complex background
scenarios, and low-to-heavy rainy conditions. To study the performance of
selected methods under these conditions, two datasets were curated: one with a
sky background and one with complex background. In this paper, one-stage
detectors and two-stage detectors are studied and evaluated. The findings
presented in the paper shall help provide insights concerning the performance
of the selected models for the task of UAV detection under challenging
conditions and pave the way to develop more robust UAV detection methods
