摘要: 针对传统地理信息采集实时性低、 数据真实性差、 细节区域描述不清的问题, 提出一种以遥感技术为基础的地理信息系统设计方案。 该系统主要由信息采集、 成像处理、 数据存储管理、 场景控制以及数据传输模块组成。 通过遥感技术远距离收集目标区域反射和辐射电磁波, 形成图像, 通过色调-亮度-饱和度(HIS: Hue-Intensity-Satuation)变换法增强图像清晰度, 并采用加权融合算法处理图像细节部分。 空间数据库对文本和图像数据分别存储和管理, 同时建立属性自关联机制, 以 Sketchup 软件对画面中地物渲染。 最后, 凭借 RS422 协议传输信息实现一机多用效果, 增强系统抗干扰性。 实验结果表明, 所提系统实际使用体验优秀, 呈现的地理信息图像清晰, 边缘细节清晰可见, 可为用户提供有效的地理信息数据。

Abstract: In view of the problems of traditional geographic information collection, such as low real-time, poor data authenticity and unclear description of detail area, a design scheme of geographic information system based on remote sensing technology is proposed. It is mainly composed of information acquisition module, imaging processing module, data storage and management module, scene control module and data transmission module.Remote sensing technology is used to collect the reflected and radiated electromagnetic waves in the target area.Transformation is used to enhance the image clarity, and weighted fusion algorithm is used to process the image details. According to the respective storage and management, the attribute self association mechanism is established. The SketchUp software is used to render the ground objects in the picture to achieve the actual control of the virtual objects. Finally, the RS422 protocol is used to transmit information in the wireless office network realizing the multi-purpose effect of one machine and enhancing the anti-interference ability of the system. The experimental results show that the proposed system is excellent in practice, the presented geographic information image is clear, and the edge details can be clearly visible, providing users with effective geographic information data.
