The invention discloses an overhead distribution line unmanned aerial vehicle autonomous inspection method and system based on GNSS positioning. The method comprises the following steps: 1) obtaining a GNSS positioning error of an unmanned aerial vehicle; 2) according to the GNSS positioning error, carrying out reverse correction on the coordinate of each base pole tower on the patrolled overhead distribution line; 3) taking the pole tower coordinate after reverse correction as a reference point, planning patrol and photographing parameters of the unmanned aerial vehicle, and forming a route; and 4) enabling the unmanned aerial vehicle to automatically execute patrol and photographing operation according to the route. The method is low in cost and quick in effect, unmanned aerial vehicle autonomous inspection of the overhead distribution line can be realized, the dependence on high-end unmanned aerial vehicle equipment and flight operators can be reduced, the labor intensity of the operators can be reduced, a
