More Information
Summary:The invention belongs to the technical field of data processing, and discloses an aerial photo offset data correction method, which comprises the following steps that: a camera outputs a feedback signal after photographing at a photographing point, and transmits the feedback signal to a control module; the control module generates a feedback moment of the current feedback signal after receiving the feedback signal; the control module requests the unmanned aerial vehicle and obtains original POS data at a feedback moment; converting the original POS data into Gaussian plane coordinates by using Gaussian projection forward calculation; according to the offset of the physical structure of the camera, substituting the attitude of the whole machine, and calculating the Gaussian plane coordinate of each imaging unit at the photographing point; and performing calculation by using Gaussian projection back calculation to obtain corrected POS data. According to the aerial photo offset data correction method and the cor
