Using the principle of limited rigid body rotation and the characteristic of angular rate input  three-sample rotation vector algorithm is derivated. To minimum attitude errors  three-sample rotation vector algorithm is optimized. Three angular rate extraction methods of singlestep entire sample recursion  multi-step entire sample and singlestep Newton backward interpolation are proposed. Under the condition of conical motion with semi-cone angle 3 and angular frequency 2rad/s  simulation is done. The simulation results show that single-step Newton backward interpolation is superior to the other two methods  and its maximum error peak is 0.01  error drift rate is 0.036/h. Experiments in three-axis flying turntable with the same parameters are carried out  and the results show that error drift rates of three-channels are less than those of traditional quaternion  which are 13.53%  12.08% and 23.68% lower respectively. It also verified that the new algorithm can perform a high accuracy under the conical motion. 2011 IEEE.   Non-linear compensation algorithm of LOS locating in aerial remote sensor (EI CONFERENCE) 会议论文  OAI收割 2011 International Conference on Electronic and Mechanical Engineering and Information Technology, EMEIT 2011, August 12, 2011 - August 14, 2011, Harbin, China 作者:  Li J.;  Li Y.;  Li Y.;  Li Y.;  Li Y. 收藏  |  浏览/下载：29/0  |  提交时间：2013/03/25 A non-linear light-of-sight(LOS) locating compensation algorithm for certain aerial remote sensor is presented in this paper. The LOS locating system is composed of two main components  which are an inertial reference frame to provide coarse LOS locating and a 2-axis Fast Steering Mirror to remove the frame's residual error. The azimuth and elevation of LOS are both affected by the FSM two-degree-of-freedom rotation  which should be dealt with to raise the accuracy of LOS location. This paper extrapolates LOS locating algorithm of FSM by coordinate transformation  and gives corresponding deviation analysis for different LOS poiting angles. It is found that the angle deviation grows rapidly with range of FSM's travel enlarging  so the deviation must be eliminated. Through the data analysis for deviation  a non-linear compensation algorithm is proved effective to reduce the error of LOS significantly. Taking LOS changing in [-3 deg  3 deg] as an example  two analytic expressions are given  and the LOS locating accuracy rises by 34 times compared with non-linear compensation unused  and the cross coupling of LOS loating is 0.08%. 2011 IEEE.   Line-of-sight locating algorithm for staring imaging aerial remote sensor (EI CONFERENCE) 会议论文  OAI收割 2010 3rd IEEE International Conference on Computer Science and Information Technology, ICCSIT 2010, July 9, 2010 - July 11, 2010, Chengdu, China 作者:  Li Y.;  Li Y.;  Li Y.;  Li Y.;  Li J. 收藏  |  浏览/下载：22/0  |  提交时间：2013/03/25 A line-of-sight (LOS) Locating algorithm for staring imaging is presented in this paper. Staring imaging is an imaging mode for aerial remote sensor  which photographs the designated earth-fixed target in muItidirections. Therefore  the details of interesting targets is available. For the target obscured or disguised  its advantage becomes more apparent. This paper proposes the method using two-axis rotation to achieve staring imaging  and establishes the system model and the associated coordinates. Adopting the method of coordinate transformation  the LOS Locating algorithm is constructed  which determines the LOS direction. For the validation of algorithm  Target Geolocation Algorithm is established using Simulink library blocks. Eventually  it proves the feasibility of the LOS Locating algorithm. This article provides a thought of LOS Locating algorithm for staring imaging. The method of coordinate transformation used in this paper can be applied to line-of-sight positioning in other imaging modes. 2010 IEEE.
