A study on data combination method in topography measurement of revolving objects 回转体形状检测的数据拼接法研究
To control the effect of error , we apply a method to solve the data combination of arrays systemic error correction based on the least squares methods 为抑制相邻排列间数据系统误差影响,运用多排列数据拼接系统误差的校正方法,这是一种最小二乘准则下的计算方法。
A series methods of data combination analyzing are selected to form the operating method system for crop discrimination . combining gis , gps , and other data from field work with rs data can determine interpretation features and set off working regions , combining rs data can enhance spatial features in order to do unsupervised classification efficiently , union of gis data enable us to join maps and extract features , to analyze crop structure , crop calendar , cultivating system 本项研究筛选出了构成运行化作物遥感识别技术体系的一系列数据复合分析方法,包括gps 、 gis数据以及其它田间作业信息与rs数据之间的复合,确立解译标志和划分作业区; rs数据之间的复合,进行图像增强,改善非监督分类效果; gis数据之间的复合,分析作业区作物结构、物候和耕作制度现状,地图拼接、特征提取等。
And we come to the following conclusions : ( 1 ) looked from the returns ratio target that , all funds achievement are better than the market datum combination ’ s in the sample time , but the funds overall achievement is inferior to interest rate ; ( 2 ) after the modification of the risk factor , our mutual funds outguess the market ; ( 3 ) there is not enough evidence that indicate that chinese security investment funds have choosing ability in the market opportunity and choosing ability in the security . ( 4 ) the achievement in the past of the fund can not represent market manifestation in the future of the fund . this article innovation mainly has following several aspects : ( 1 ) have established the overall target of a appraisal fund achievement and gone on the real example to analyze with the mathematics model , having solved the inconsistency problem of appraising the result of many kinds of 在此背景下,本文希望通过借鉴国外对基金业绩评价方面的经验,结合我国的国情尝试尽可能真实的、多角度分析我国证券投资基金在不同市场时期的业绩特点,如投资基金的回报及其承担的风险,基金经理的择时能力和选股能力究竟怎样,基金业绩是否具有持续性等等,为基金投资者、监管者、基金管理公司以及基金的发展提供一些参考,以引导社会资源更多地流向拥有理性投资理念、资产管理能力出色的基金管理公司,实现资源的优化配置,进而推动市场投资理念走向成熟。
In this article , author simulate the network structure by ns2 simulation platform , including data transmission 、 data collecting 、 data combination and so on . author describe the whole process of wsn communication , finish the low - consume research on wsn from another point of view - -本文的后几章详细描述了该无线传感器网络通信模拟架构的实现过程,包括数据接收、数据感应、数据融合、数据发送等多个步骤,并使用ns2仿真平台进行仿真实现,从另一个角度对低功耗安全通信进行探究。
The coordinate systems and time systems are described in detail at first , then the paper presents the whole algorithm containing line of sight generation and projection attitude data combination scan mirror calibration , find corresponding grid cell , resample . at the same time , scan gaps and detector delays are analyzed in detail 论文首先对校正过程中用到的时间系统和坐标系统作了介绍,然后给出了完整的校正算法,包括视线产生和投影、姿态合成、扫描镜校正、寻找校正图像空间像素到未校正图像空间的对应像素位置、重采样这几个部分,并在相邻扫描行间隙的插值上采用了简洁的方法。
