**Vision-Based Localization (VBL) plays a crucial role in modern technology by enabling autonomous navigation and enhancing user experiences. VBL techniques use cameras and computer vision algorithms to estimate a UAV's position and orientation based on visual data, providing accurate localization even in environments with weak or no GPS signals. The advancements in VBL have increased adoption across various industries, including autonomous vehicles, augmented reality, robotics navigation, surveillance, security, and reconnaissance missions. However, users still face challenges when implementing a VBL system to operate an autonomous vehicle, such as lighting variations, dynamic environments, and computational costs. To mitigate these issues, high-range cameras, multi-sensor fusion, and GPUs can be employed. Overall, VBL is a promising technology that offers several benefits, including GPS-independent navigation, rich data source, scalability, and adaptability.
