【摘要】 图像全站仪系统是近几年出现的一种新的数字近景摄影测量系统,在图像全站仪内部集成有广角和长焦两个CCD相机,它可以实现真正的“无接触测量”。本文研究了该系统的组成及其工作模式,对系统的理论基础进行了深入剖析。本文还分析了图像全站仪系统相机检校软件PI-Calib的检校原理,并针对原方法的不足提出了基于LCD的相机检校新方法,使相机检校更方便、快捷。同时,分别对图像全站仪系统进行了近距离和远距离的建模实验,通过分析实验数据总结出了图像全站仪系统的建模精度,给出了估算公式。最后探讨了该系统在水利水电、土方量测、文物保护和建筑物建模领域的应用。更多还原

【Abstract】 Recent years, it appears a new digital close-range photogrammetry system called Image Total Station System. There are two CCD cameras inside the image total station, which can realize real ’no-touch measurement’. The essay studies the constitution of system and work mode, also its basic theory. It also analyzes the principal of software PI-Calib for camera calibration, which is a part of Image Total Station System. Through experiment, I find some its shortages, and put forward a new camera calibration method based on LCD. That makes the work more convenient and faster. I carry on some close-distance and long-distance experiments. Through analyzing the data, it sums up the model precision created by the Image Total Station System and put forward the estimated formula. Finally, it discusses the system’s applications on water conservancy, square measurement, cultural protection and building modeling.更多还原
