According to the factors that affect the precision,working efficiency and imaging quality of aerial photogrammetry,a method of building the calibration field for unwinding the inner and outer azimuth elements of aerial camera was proposed in this paper,and the high precision calibration of the interior orientation elements of the aerial camera was realized.On this basis,the design and practice of a kind of meet the requirements of the existing photogrammetry production of high-performance wide angle aerial camera,the device has the capability of more than 80°transverse field of view,stable exposure frequency of 2 Hz,automatic sensing of flight speed and terrain height,and automatic determination of exposure interval according to photogrammetry's rules.The production practice of tens of thousands of square kilometers showed that the color of wide-angle aerial camera's image was natural,the overall texture was clear,it supported aerial photography in the environment of large speed high ratio,and its integrated operational efficiency was more than twice that of the international brand aerial camera today.
