Abstract
In this paper,the collinearity equation of the remote image is described by the unit quaternion.Then the unit quaternion bundle adjustment model is constructed.For the nonlinear problem of the collinearity equation,the LM (Levenberg-Marquardt) method is proposed to solve the quaternion bundle adjustment model.The robust estimation method of the UAV image orientation elements is available based on the Danish method.The feasibility of the proposed method is validated based on the simulation and UAV images.The experiment also shows that the reliability of the LM method is equal to the unit quaternion method.The robust estimation method of the UAV image orientation elements is available and reliable based on the Danish method.关键词
