【摘要】：区域地质调查工作是地质工作的基础、是资源勘探的前提,其采集的数据种类多、信息量大,采用移动GIS技术实现数字地质调查对于改善地质数据的全面性和准确性,提高数据采集效率具有重要意义。本文分析已有系统的不足,结合新平台及新技术带来的优势,对关键问题及其解决方案进行了重点研究。在研究PRB数字地质调查模型、GPS定位原理、图像配准方法及一般流程、多点触控技术原理、手势交互分类和手势设计原则、移动终端上的文字录入技术等理论的基础上,本文结合对野外地质数据采集及后续制图工作中的实际需要、地质数据的规律性、移动终端的性能限制及地质调查系统中的任务特点等的具体分析,设计了基于PRB模型的数据采集流程、PRB过程中的大量文字录入方案、移动终端上手图与GPS点的实时配准方案,以及基于多点触控技术的手势交互规则和手势识别响应机制,并就整体架构及图层组织方式对系统进行了总体设计。其中,在进行手势交互方案设计时,为了满足手势设计原则,本文将系统中的图层划分为点图层及线图层两类并分别对其状态转移过程进行分析,为手势设计提供了重要依据。最后,本文根据以上设计方案实现了基于GeoGIS的数字地质调查系统。
[Abstract]:Regional geological survey is the foundation of geological work and the premise of resource exploration. It collects many kinds of data and has a large amount of information. Using mobile GIS technology to realize digital geological survey can improve the comprehensiveness and accuracy of geological data. It is of great significance to improve the efficiency of data acquisition. This paper analyzes the shortcomings of the existing systems, combines the advantages of the new platform and new technology, and focuses on the key problems and their solutions. Based on the research of PRB digital geological survey model, the principle of PRB positioning, the method and general flow of image registration, the principle of multi-touch control technology, the principle of gesture interaction classification and gesture design, the text input technology on mobile terminal, etc. This paper analyzes the actual needs of field geological data collection and subsequent cartographic work, the regularity of geological data, the performance limitation of mobile terminals and the characteristics of the tasks in geological survey system. This paper designs a large number of text input schemes in the process of data acquisition based on PRB model, a real-time registration scheme between hand map and GPS points in mobile terminal, and gesture interaction rules and gesture recognition response mechanism based on multi-touch technology. In order to satisfy the principle of gesture design, the overall design of the system is carried out on the basis of the overall architecture and layer organization. In this paper, the layers in the system are divided into point layer and line layer, and their state transition process is analyzed respectively, which provides an important basis for gesture design. Finally, the digital geological survey system based on GeoGIS is implemented according to the above design scheme.
