Problems solved by technology

[0004] The above two modeling of the magnetic field environment of the inspection UAV simulation system did not consider the particularity of the inspection UAV flight environment, did not consider the interference of other magnetic fields, but only considered the geomagnetic field environment for modeling. The disadvantage is that it cannot simulate the real flight environment of the transmission line inspection UAV

Description

technical field [0001] The invention belongs to the technical field of inspection unmanned aerial vehicle inspection line simulation technology, and relates to a magnetic field environment correction method of a transmission line inspection unmanned aerial vehicle simulation system. Background technique [0002] With the wide application of inspection drones in the power industry, operating inspection drones has become an essential skill for line employees, but obtaining a pilot certificate cannot meet the skill requirements for inspection drones. Therefore, a virtual flight training platform for inspection drones, which is a professional inspection drone line inspection simulation software, has emerged. There is an urgent need for a more realistic simulation of the actual environment in the virtual inspection UAV flight training simulation system. The accurate establishment of the inspection UAV's flight magnetic field environment model is a very important item in all envir...
