摘要： 针对三维空间定位过程中,对定位的精度要求高以及要求对位置信息响应快的特点,在分析了传统定位算法的基础上,通过对定位过程中产生的误差区域研究发现,空间4个定位参考点按照某种分布可以提高定位精度,更好地提供定位服务.由此提出了空间定位参考点分布定理(DSLRD),设计并实现了在三维空间定位过程中新的定位参考点分布算法(LRND),该算法不仅大量地节省了计算和存储资源,而且保证了定位计算的实时性和准确性.

Abstract: In view of the requirements for high locating accuracy and fast response to location information in 3-D space, the region of errors due to locating an unknown node is studied on the basis of analyzing the conventional 2-phase locating algorithm. It is found that the locating accuracy can be greatly improved if there are four locating reference nodes distributed according to a certain mode which is available to provide better service for positioning. Thus, the theorem of distribution of spatial locating reference nodes (DSLRD) is proposed to design and implement a new locating reference node distribution (LRND) algorithm in 3-D space. The new algorithm will not only save greatly the computation/storage resources but ensure the real-time veracity of locating computation.
