	The application of template matching arithmetic on Strap-down North Seeking System (EI CONFERENCE) 会议论文 OAI收割 2011 International Conference on Mechatronic Science, Electric Engineering and Computer, MEC 2011, August 19, 2011 - August 22, 2011, Jilin, China Li D.-N.; Zhu W.; Chen T. 收藏 \| 浏览/下载：19/0 \| 提交时间：2013/03/25 In order to solve the problem of self-determination directional of theodolite equipment based on dynamically tuned gyroscope is proposed. The principle of the Multi-position Strap-down North Seeking System is introduced. Mathematical model of the system is discussed. The factors that influence the precision are analyzed. In order to fit the curve of sampling data back-propagation neural network arithmetic is used in data processing. As templates curve model is saved at database of the VC software. The template matching arithmetic advanced the measure precision of this system. The measure time of the system is shortened within 1 minute so it can save time for theodolite. 2011 IEEE.
