The invention discloses an unmanned aerial vehicle aeromagnetic measurement system and method. The system comprises a flight parameter acquisition device, a compensation device and an optical pumpingmagnetometer. The flight parameter acquisition device, the compensation device and the optical pumping magnetometer are installed on an unmanned aerial vehicle. The output terminal of the flight parameter acquisition device is connected to the input terminal of the compensation device and is used for collecting the real-time flight parameter of the unmanned aerial vehicle and outputting the real-time flight parameter to the compensation device. The output terminal of the optical pumping magnetometer is connected to the input terminal of the compensation device and is used for measuring the magnetic field intensity of a position where the unmanned aerial vehicle is located in real time and sending the magnetic field intensity to the compensation device. The compensation device is used for carrying out real-time compensation on the magnetic field intensity according to the real-time flight parameter. By using the unmanned aerial vehicle aeromagnetic measurement system and method, data compensation can be completed in real time and work efficiency is increased.
Description
technical field [0001] The invention relates to the field of unmanned aerial vehicle geophysical detection, in particular to an unmanned aerial vehicle aeromagnetic measurement system and method. Background technique [0002] Aeromagnetic surveying can provide information and interpretation results for geological mapping and large-scale geological structure research, evaluation of metal ore and solid mineral resources, prediction of oil and gas mineralization prospects, engineering geology and environmental monitoring. In the past, aeromagnetic surveys were carried out on military aircraft or helicopters. For domestic aeromagnetic surveys, Y-5 and Y-12 planes are generally selected. For the sake of flight safety, the general flight altitude is above 1,000 meters from the ground surface. The speed is generally hundreds of kilometers per hour. Therefore, the advantage of aeromagnetic survey is high acquisition efficiency. The disadvantage is that due to the influence of flight...
