【摘要】：实景影像是指一体化集成融合管理的时序序列上具有像片绝对方位元素的地面立体影像。可视、可量测、可挖掘实景影像包含了传统地图所不能表现的空间语义,代表着地球实际的物理状况,是带有与人们生活环境相关的社会、经济和人文知识的地球全息图。近年来,实景影像数据以其可量测、可提供城市景观立面图像和可挖掘自然及人文社会信息等诸多优势,逐渐成为测绘领域4D产品的重要补充,并在“数字城市”的众多应用中起到可支撑性作用。 随着车载实景影像采集技术的快速发展和城市实景影像应用的普及,在“数字城市”和“智慧城市”的建设进程中,各级测绘管理部门与众多的城市职能管理部门(如城管)根据各自的需要采集了大量的实景影像数据、构建了不同应用目的的实景影像系统。针对当前实景影像应用建设中数据来源多样、系统异构所导致的实景影像访问范围小、数据利用率低等共享难题,本文在深入分析和借鉴OGC网络空间服务规范体系的基础上,结合实景影像数据及其应用的特点,从改善实景影像数据共享方式、提高实景影像应用交互能力的角度,提出了网络实景影像空间服务(Web Image Service, WIS),研究了包含服务描述、发现、接口及交互的服务模型。在此基础上,论文结合“天地图·城市”和“数字城管”等应用,研究了服务的实现方法,并验证了服务的可用性和易用性。 本文主要的研究内容和成果如下： 1.分析了OGC空间服务体系中代表着数据服务、展现服务及处理服务的典型空间服务规范,并从这些规范是否能够改善实景影像数据共享方式的角度切入,提出了提高实景影像应用交互能力的WIS模型结构。 2.根据WIS模型结构,从服务描述、服务发现、接口设计及交互方式四个角度研究了WIS的服务模型,研究了服务描述的表述元素、服务能力及功能序列；探讨了服务发现的关键字和空间信息匹配方式；设计了实景影像能够实现的九个服务接口；分析了服务的交互方法。 3.从硬件层、数据层、业务层及接口设计实现了WIS的原型,以海安市实景影像为试验数据,分别结合“数字城管”和“天地图·城市”地图资源构建了WIS原型的应用示例,提炼了WIS的应用模式,验证了WIS的可用性与易用性。
[Abstract]:Real scene image is a ground stereo image with absolute azimuth elements in the sequence of time series integrated and integrated management. Visual, measurable and mining images contain spatial semantics that cannot be represented by traditional maps, and represent the physical conditions of the earth. They are holograms with social, economic and humanistic knowledge related to people's living environment. In recent years, the real scene image data with its measurable, can provide urban landscape elevation image and mining natural and human social information and many other advantages, gradually become an important supplement to the field of surveying and mapping 4D products. And in the "digital city" in many applications play a supporting role. With the rapid development of vehicle real scene image acquisition technology and the popularization of urban real scene image application, in the construction process of "digital city" and "intelligent city", Surveying and mapping management departments at all levels and many urban functional management departments (such as urban management) have collected a large number of real scene image data according to their respective needs, and have constructed a real scene image system with different application purposes. In view of the difficulties of sharing real scene image such as diverse data sources, small access range and low data utilization rate caused by heterogeneous systems, this paper analyzes and draws lessons from the OGC network space service specification system in depth. According to the characteristics of real scene image data and its application, from the point of view of improving the sharing mode of real scene image data and enhancing the interactive ability of real scene image application, this paper puts forward the research of network real scene image space service (Web Image Service, WIS), including service description and discovery. Interface and interactive service model. On this basis, the paper studies the implementation method of the service, and verifies the usability and ease of use of the service, combining with the application of "Tian Maps City" and "Digital City Management" and so on. The main contents and achievements of this paper are as follows: 1. This paper analyzes the typical spatial service specifications that represent data service, display service and processing service in OGC spatial service system, and from the angle of whether these specifications can improve the sharing mode of real scene image data, This paper presents a WIS model structure to improve the interactive ability of real scene image application. 2. According to the structure of WIS model, the service model of WIS is studied from four aspects: service description, service discovery, interface design and interaction mode. The description elements, service capability and function sequence of service description are studied. The key words and spatial information matching methods of service discovery are discussed, nine service interfaces that can be realized by real scene image are designed, and the interactive methods of service are analyzed. 3. The prototype of WIS is designed from the hardware layer, data layer, business layer and interface. Taking the real scene image of Haian city as the experimental data, the application examples of WIS prototype are constructed by combining the map resources of "Digital City Management" and "Tian Maps City", respectively. The application pattern of WIS is refined to verify the usability and ease of use of WIS.
