This paper utilizes the successful tracking ability of the iterated optical flow approach within the tracking distance of less than 30 pixels, and develops a new method for image matching and determining the corresponding 3D points. Test results verify that it can determine about one point per 1.5m2 (≈9×9pixels). Also, it can automatically determine one point per 6.8m2 (≈20×20pixels) and one point per 0.2m2 (≈3×3pixels) in occlusion and tree areas, respectively. Moreover, those matched points are checked by aero triangulation. For example, totally 7473 tie points on 6 images are regarded to be successfully matched from 6 overlapping images in a strip by the proposed method. Only 50 tie points are mismatched points detected by reliability theory.

By deriving the initial alignment errors equation of SINS, and considering the gyro drift and the accelerometer bias, the paper first introduces the nonlinear errors model with large heading uncertainty. Then, through computer simulating, the paper discusses the reason of nonlinear robust extend Kalman filter divergence, and based on the practical errors model, simplifies the arithmetic of nonlinear robust extended Kalman filter. And then, because nonlinear robust expanded Kalman filter has high adaptive ability but diverges easily, the paper presents a modified nonlinear adaptive filter algorithm based on literature [1], which not only could ensure the accuracy of alignment, but also could improve the ability of adaptive. Finally, when the extended Kalman filter, nonlinear strong tracking adaptive Kalman filter, nonlinear robust extend Kalman filter and modified nonlinear adaptive Kalman filter are used to simulate the nonlinear system, the paper analyses the level alignment accuracy and heading alignment accuracy of these filters under different errors, including model error and noise error.
