The invention discloses a positioning method of power transmission line inspection personnel and belongs to the electric power equipment inspection technology field. The method comprises the following steps of acquiring first positioning data of a position where inspection personnel is located, and processing and acquiring second positioning data of a position where an inspection pole and tower is located; converting the first positioning data and the second positioning data into corresponding latitude and longitude data; processing and acquiring a longitude distance of the position where the inspection personnel is located and the position where the inspection pole and tower is located along a longitude direction, and processing and acquiring a latitude distance of the position where the inspection personnel is located and the position where the inspection pole and tower is located along a latitude direction; processing and acquiring an actual distance between the position where the inspection personnel is located and the position where the inspection pole and tower is located; and according to the actual distance, navigating the inspection personnel. The technical scheme has the advantages that an inspection track of the inspection personnel is convenient to check in real time and historical track data is convenient to inquire; and the inspection personnel can conveniently select an optimum path through which an inspection place can be arrived at and inspection efficiency is increased.
