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。

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.
