This review paper investigates the integration of (UAVs) in assisting car accident examination through the utilization of image processing techniques and the encryption of data stored in (UAVs). This work was conducted in an effort to investigate the existence of systems in research. The paper addresses key questions regarding the use UAV-based solutions for car accident examination, the main advantages, and challenges of (UAV) adoption in this context, the current (UAV) applications in car accident examination, and the use of image processing techniques for examining car accidents. By integrating existing literature and research findings, this review aims to provide insights into the potential benefits and limitations of UAV-assisted car accident examination, as well as the role of image processing in enhancing data analysis and security within this domain which is lacking in research.
