The invention discloses a helicopter power line inspection realization method and realization system. The method comprises the following steps: sequentially obtaining multiple line inspection pictures according to a prestored power transmission line and a pole shooting sequence through a long-focal-length single lens reflex camera arranged on a helicopter; transmitting the line inspection pictures to a flat computer through a helicopter line inspection shooting control used for transmitting picture data; and the flat computer, according to pole numbers corresponding to the multiple line inspection pictures, classifying the line inspection pictures according to the pole numbers and storing the pictures in a table taking base poles as columns, corresponding to the pole numbers. According to the invention, the line inspection pictures are automatically obtained and automatically classified and stored, pictures with power transmission line defects can be identified, the line inspection efficiency is greatly improved, and the intensity of manual operation is reduced.
