Fusion processing method for helicopter anti-collision earth surface power line

The invention provides a fusion processing method for a helicopter anti-collision earth surface power line which is good in safety, low in maintenance cost, small in information loss and high in fusion precision. According to the technical scheme, a helicopter control module divides fusion processing of the anti-collision earth surface power line into an iron tower power line alarm prompt stage A and a real-time flight execution stage B. In the stage A, the radar position is fixed on the ground, data of a grounded feeder column sensor system are collected, and error factor parameters of the system are obtained; the helicopter control module obtains information of the projection of an iron tower in the geographic coordinate system and information of the projection of the iron tower in the geographic coordinate system; power lines between the iron towers are drawn, the positions of the iron towers relative to the helicopter are calculated, data collected by a navigation sensor and a course sensor and fusion dat
