UAV technology, originally developed for military reconnaissance in the early 20th century, has evolved into a versatile tool in both military and civilian applications. This paper explores the progression of UAV image transmission technology, from early analog systems to modern digital transmission. Key advancements in compression algorithms, including the use of H.264 and H.265 standards, have significantly improved data transmission efficiency, image quality, and system stability. The integration of wireless communication technologies such as Wi-Fi, 4G, and 5G has broadened UAV applications across various sectors, including aerial photography, agriculture, logistics, and disaster management. Additionally, emerging technologies such as millimeter wave communications, 6G networks, and artificial intelligence-driven image processing will further enhance the performance and reliability of UAV systems. The future of UAV image transmission lies in the adoption of these innovations, allowing for improved bandwidth efficiency, real-time video transmission, and expanded applications in smart cities, telemedicine, and precision agriculture.
