The invention discloses a high-power zoom unmanned aerial vehicle aerial high-definition multi-dimension real-time investigation transmitting method. The method comprises the following steps that firstly, a monitoring computer starts a monitoring program, and a satellite navigation unit starts a GPS navigation program; secondly, a high-definition high-power zoom action camera collects video images according to the track of the monitoring program, and a vehicle-side image processing module processes the images; thirdly, a video image wireless transmitting module and a video image receiving module cooperate to complete wireless sending and receiving of image signals; fourthly, a central station image processing module processes the received image signals, and the received image signals are displayed on a terminal. According to the method, visual navigation, image recognition and obstacle avoidance are supported, parameters can be properly changed under the situation that the influence of transmission delay is avoided, and thus the image recognition rate is increased; a satellite communication network mode and a traditional communication mode are fused together, high-capacity image data can be exchanged at a high speed, and high safety is achieved.
