查询词典 accuracy grade

Four sets of actual aerial photos are used to test;which are at different scale and in different terrain.The empirical results verify that image elements of exterior orientation obtained by a POS can satisfy the accuracy requirements of topographic mapping,no matter which scale and terrain the empirical block is classified to.However,to satisfy the accuracy requirements of object point in elevation,the accuracy requirements of exterior orientation elements are at least one time higher than that in planimetric mapping.

In the presently mobile position technology, GPS's position method is one of the best. This method owns high accuracy less than 15 meters, and can be used with GPS chip in the mobile station. But GPS chip with the high price makes this technology difficult to popular. Therefore, the position technology of GSM communication network is attention to the people gradually. TOA or AOA is more often used among position technology, these methods need only the help of the position measuring instrument to attain time and angle for position calculation. They have good position accuracy, but they are also too expensive to popular. Every positioning technology has its bottleneck such as external environment influence, cost and positing efficiency. Therefore, the purpose of this research lies in finding out the mobile station location and does not emphasize the raise of the accuracy and it only uses existing information to finish position action.

在目前的行动定位技术中，以GPS定位技术为最佳，不仅拥有少於15公尺的高定位精确度，更只需在行动端加装GPS晶片即可使用，可惜高价格的GPS晶片使得此技术难以普及化，因此，以GSM通讯网路为主的定位技术逐渐受人们所重视，其中，又以TOA或AOA等定位技术较常被使用，仅透过位置测量仪器的帮助，便可取得定位所需的时间和角度，并且拥有不错的定位精确度，可惜也受到高价格因素的关系难以普及化，而每种定位技术都有其瓶颈存在，不论是外在环境的影响、成本和定位效能上；所以，本研究的目的在於找出行动端位置，即利用现有的资讯（细胞识别码、讯号强度等）来完成定位动作，而非强调其定位精确度的提高。
