Abstract: Embodiments of the present invention relate to a method for storing a UAV system log and a UAV image transmission system. The method for storing a UAV system log includes: generating a run log at an end of a UAV, the run log including an exception log generated when an exception occurs in the UAV system; and storing the exception log into a preset first storage space. With the method, after a UAV system is shipped, exception logs can be exported in time and sent to technicians to locate problems. A routine run log of the system that has a relatively large data volume may be stored in a mass storage device of a UAV or a mobile terminal, and may be used in research and development or test reproduction.
