Basing on hough transform , two - valued spectral pattern image is fitted to linear array single - element wide and different - distance apart , and then position information of every line in the array is noted by order . searching the fitted linear array by initialized value and the identifying goal is accomplished 以霍夫变换为理论依据,将二值化谱线图像拟合为单像素宽、距离不等的直线组,并按次序记录每条直线的位置信息;根据初始化的预定值,搜索拟合所得直线,完成谱线的识别工作。
On the basis of gsm system position principle and position gateway realizable technology , position server software system and engineer application software system ( vehicle administration system ) that is based on the position service were exploited . the emphasis was the completion of the following modules : the network connection of position server , position function , treatment of short message , the database connection and the outer connection of the visiting position information and short message of engineer application software system 作者在深入掌握gsm系统定位原理及定位网关实现技术的基础上,参与开发了定位服务器软件系统与基于定位服务的工程应用软件系统(车辆管理系统) ,其中重点完成了定位服务器的网络接口模块,定位能模块,短消息处理模块,数据库连接模块和工程应用软件系统的访问定位信息与短信的外部接口模块
Thirdly , the paper analyzes the terrain entropy in detail . the primary bug of this algorithm is that discards the relative position information of terrain data and normalized processing . based on this , the kalman filter for optional estimation is offered and the maximization of mutual information is synthesized , the performance of algorithm is improved , the filter divergence is restrained 基于此点,论文对地形熵算法做了详细的分析,提出了基于最优估计思想的卡尔曼滤波方法,并综合使用了交互信息量等方法,改进了地形熵算法在tf ta中应用的性能,取得了较好的效果。
Landslide is a comprehensive discipline . in the landslide study , it involve a large amount of information related to three - dimensional space and position , for instance geological information , position information , etc . but it is difficult to grasp any information in the past technology of studying , and it is unable to carry on fictitious engineering design , assign and construct and then analyse the result in three - dimensional space 滑坡学是研究滑坡的综合性学科,在滑坡研究中,会涉及大量与三维空间及位置有关的信息,如地质信息、位置信息等,而在以往研究技术中很难把握这些信息,并无法实现在三维空间进行虚拟工程设计、布置和施工等进而分析其效果。
The system consists of the control center and the monitoring terminal . it can monitor the operational parameters and positioning information automatically , help the waterway administration to get the operational status of navigation mark rapidly and find out the faults in time , improve the reliability of navigation mark , increase the safety of the waterway transportation 系统由控制中心和监控终端组成,自动监控航标的运行参数和位置信息,帮助航道管理部门快速地掌握航标的工作状态,及时发现航标的故障,提高航标的可靠性,增强航道运输的安全。
