动态位置参考方法被认为是未来快速发展的Telematics领域的核心技术之一。动态位置参考方法弥补了传统的预编码位置参考算法存在的主要缺陷,提高了算法的易用性和位置识别的准确度。本文基于目前的导航电子地图,提出了动态位置参考的逻辑数据模型、特征提取规则和对应的目标识别算法,并依据上述动态位置参考方法的理论,针对我国路网数据特征,在北京导航电子地图上进行了位置参考的特征提取和识别的试验,验证了该方法的可行性和实用性。

On-the-fly location referencing is now considered as a key technology for many future applications in the fast developing world of Telematics. On-the-fly location referencing method overcomes the defections which exist in the traditional pre-coding location referencing algorithm. The usability of matching algorithm is improved and the accuracy of position recogni- tion is increased. On the basis of current navigation electronic map, logical data model and feature extraction rules and corresponding target recognition algorithm is proposed. According to the above theory of on-the-fly location referencing method, in allusion to the characteristics of road network, feature extraction and recognition of location referencing is tested on the corresponding areas of Beijing navigation electronic maps. So the feasibility and applicability of that method is verified.
