| 英文摘要 | A two-step method was proposed to estimate parameters of long focal mapping camera by means of calibration field. The direct linear transform formulation(DLT) was used to obtain initial values for the hybrid LMQN iterative speed method by giving the feature points and the images taken from several positions and attitudes, and the whole process of calculating and experiment was described in detail. Compared with precise angle measurement method, operation and recording of accurate equipment are dispensable. It was only needed that images of calibration field with precise position information were taken from several different positions and orientations. The calibration results of experiment based on calibration field method indicate that the maximum re-projection error of feature points is 2.471 pixel, the calibration accuracies of principal point and principal focal distancereach 9.7 m (2 pixel) and 4.3 m (1 pixel), respectively, the calculated position accuracy of the camera is 0.035 m, which meets precision requirements of mapping application. 2018, Science Press.
