摘要	This study analyzes The effects of aircraft's attitude, speed, and height on the overlap of an obliqueaerial camera was analyzed in this study, and acorresponding compensation method was developed. The calculation of oblique imaging overlap using coordinate transformation was introduced based on ageo-location algorithm and the Gauss-Kruger projection. In the case of single parameter variations, different formulas were provided by the geometric method, and the results were consistent between coordinate transformation and geometric methods. In the case where the three parameters varys imultaneously, the geometric method did not work adequately, and the coordinate transformation method should be used. In the case where the varied angle value of the aircraft attitude was below 1, the deviating value between real covered area and expected area was attained by thecoordinate transformation method. The usage of camera's azimuth and pitch angles to compensate the effect of aircraft attitude on overlap was introduced. For the variation of aircraft speed and height, changing the imaging period according to the aircraft real time values was suggested, and a new formula regarding imaging period was provided. The validity of the compensation algorithm was verified by simulation and real flight. The result shows that when the camera's field of view is below 0.88, the deviation between mean and expected values of real overlap is approximately 1%, if the target area is flat. 2020, Science Press.
