The invention discloses a rapid map planning method for an unmanned aerial vehicle (UAV) electric power line patrol system. The method comprises: recording support coordinate information and spacer distance information in a table, performing formatting, and performing batch data import; setting the requirement condition of a cruise point, and according to the calculating method of spherical arc length and azimuth, performing calculation to obtain position data of the cruise point; using a template coupling algorithm, coupling a quadrilateral locator of a saved picture to obtain corresponding position data; and according to a cruise point file and support information, generating a task file used in an earth station and performing navigation. The manufacture efficiency and accuracy of a route map for a UAV line patrol system are efficiently improved.
