Hello, UAV aerial photography can be widely used in national ecological environment protection, mineral resources exploration, marine environment monitoring, land use investigation, water resources development, crop growth monitoring and yield estimation, agricultural operation, natural disaster monitoring and evaluation, urban planning and municipal management, forest pest protection and monitoring, public safety, national defense, digital earth and advertising photography. , has a broad market demand. At present, the main application fields are pesticide spraying, aerial photography and aerial mapping. Due to different operational requirements, these three UAVs have obvious characteristics differences. Most of the plant protection drones spraying pesticides are rotorcraft, equipped with internal combustion engines, with relatively large load, slow flight speed and low altitude; Most aerial drones are multi-axis rotorcraft, driven by electricity, flying smoothly and flying at high altitude; Most UAVs for aerial surveying and mapping are fixed-wing UAVs with long range, fast flight speed and high flying height. At present, China's civil drone production units have gradually grown. For example, Kunming Jinying UAV specializes in the design, production, sales, aerial survey and aerial photography services of aerial survey and aerial photography UAV equipment, and is the top design, manufacture and flight service provider of aerial survey and aerial photography UAV in China. Jinying 1, Jinying 2 vertical take-off fixed-wing UAV, Jinying 3 vertical take-off hovering fixed-wing UAV, Jinying 650 special UAV, Jinying 1000 eight-axis aerial photography aerial photography aerial photography aerial photography aerial photography, Jinying 1600 large load-bearing rotor flight platform and Jinying S 1 aerial photography aerial photography aerial photography me. Hope to adopt yo, thank you.
