【摘要】 航空遥感数字传感器系统(简称数字航测相机)是一种能够同时获得立体影像和彩色多光谱影像的多功能、航空遥感数字成像设备。自2000年以来,数字航测相机已陆续开始在国内外的测绘行业使用,开启了数字航测相机替代胶片航测相机的新时代。瑞士Leica测量系统公司的ADS40数字航测相机是线阵相机的代表。ADS40数字航测相机是基于线阵CCD推扫式的航空遥感数字传感器,集成了高精度GPS和惯性测量单元IMU。GPS/IMU是ADS40航空数字传感器的核心设备。GPS/IMU技术是对传统的摄影测量的重要革新,是未来遥感和航空摄影测量技术发展的趋势。论文主要对ADS40航空数字传感器的地面数据处理系统的技术、方法与应用进行研究。内容包括;1.系统地分析了ADS40数字航测相机地面数据处理的数学模型,为ADS40数据地面处理技术方案和软件功能测试奠定了理论基础。2.在分析和总结ADS40地面数据处理软件结构的基础上,对试验区进行了设计,并组织了飞行航摄,获得了测试所需的完整的数据。3.利用试验数据对ADS40地面数据处理软件功能模块进行了功能和性能测试。4.在对ADS40地面数据流分析的基础上,结合现有的作业质量控制的经验,设计了适合于生产的数据处理工作流程,并对数据处理过程中的质量控制进行了研究,在试验中得到了验证。5.结合对实际的ADS40试验区数据进行地面数据处理,提出四种数据处理的技术方案,检查数据处理的精度,对ADS40数字航测相机数据处理的性能、功能、技术指标进行综合评价。通过对ADS40线阵数字航测相机的地面数据处理技术、方法与应用的研究,结合目前国内开展的生产试验与实践,对ADS40数字航测相机的摄影测量成图过程、精度进行了分析,并对地面数据处理进行了充分的试验验证及分析总结,形成了一套完整可行的ADS40地面数据处理的流程以及生产试验方案。更多还原

【Abstract】 The Aerial Digital Sensor or Digital Photography Camera is defined as functional and digital device that can acquire airborne imagery data with stereo viewing and spectral band. Since 2000, when the aerial digital sensor was applied in the field of Surveying and Mapping at home and abroad, it starts a new age that digital camera substitutes for film camera. Aerial Digital Sensor ADS40 is a typical representative of product made in Leical Geosystems, Switzerland.ADS40 is Leica’s product based on the CCD pushbroom principle. It is linear arrays CCD sensor which integrated GPS/IMU technology to directly acquire the position and attitude of sensor at exposed time. GPS/IMU device is the most important part of ADS40. GPS/IMU technology is a tendency of developing the Photogrammy and Remote Sensing, at same time it is also the most important reform to the traditional photogrammy.This paper is mainly a study of the technology, method and application of the Ground Data Processing of ADS40. It includes:1. Analyse the photogrammy principle and mathematical model used for the Ground Data Processing of ADS40.It provides the foundation for the design of block test field for verification and test of ground processing software.2. Based on the analysis and summary of the components of ground processing of ADS40, we created the design for block test field for verification and cross-line test field for cablibration, arranged or organized aerial photography and acquired all necessary test data of photogrammetric area.3. Based on the analysis of ADS40 data and function test of software, we create data flow diagram for the ground processing of ADS40.The flow diagram guides production of test field. Then, we test the software function of ground data processing. The correct and complete data flow diagram does help to establish the workflow of product. Finally, we do research on quality control and check for data processing.Connected with past experience of quality control, we find that the workflow of product and method of quality control is very valid.4. With the practice of experimentation data of ADS40, we provide with four different cases for ground data processing, analyze the accuracy of ground control points and give the comprehensive estimate to the capability of data processing of ADS40.To sum up, through the study of the technology, method and application of ADS40’s ground data processing in experimentation, we form a set of practical workflow and some effective experiment cases.更多还原
