The invention has the following beneficial effects:
the vision is not required to be frequently switched on the air and the image monitoring display, so that the fatigue is reduced, the time waste is reduced, and the operation efficiency is improved.
The transmission channel of each set of device is set by a user, and a plurality of sets of unmanned aerial vehicle systems can be arranged, and the image transmission systems are respectively and simultaneously carried for executing tasks without mutual interference and simultaneously working. An operator can switch in the visual field of the multiple unmanned aerial vehicle systems through quick frequency searching operation, and fewer people and fewer receiving devices can monitor the multiple unmanned aerial vehicle systems.
Each set of device occupies two image transmission channels, but the two image transmission channels are bound into groups, and a ground image receiving end (namely VR glasses) can automatically and accurately receive one channel only by searching the other channel, so that the searching efficiency is improved. When multiple sets of systems are used together, two receiving channels of the ground image receiving end are prevented from receiving video signals from two different unmanned aerial vehicles, and therefore receiving disorder is avoided.
