非量测型数码相机的技术性能近年来得到不断提高，由于其价格低廉、携带方便、数据处理容易等特点，将数码相机应用于数字近景摄影测量方面显现出非常重要的意义。 将非量测型数码相机与经纬仪（或全站仪）望远镜紧固连为一体，并且采用的是一个可重复拆装、具有高定位精度的联接装置，构成了所谓的摄影经纬仪系统。在该系统的应用中，文中首先提出了数码相机的内方位元素的检定方法、数码相机与经纬仪的相对位置关系解算公式以及野外摄站外方位元素的解算关系式，然后利用室内检校场、数字摄影测量系统和单像空间后方交会软件进行了检定和试验。 针对系统应用于工程现场时各测站上经纬仪中心坐标的获取，提出了具体测量解算方法。对于数码相机立体像对的构成，采用的是在任意两测站上各选择一张像片构成左右立体像对，并继续利用室内控制场和地面立体摄影测量前方交会软件来对系统可实现的精度进行评价。最后在实验基础上总结了影响系统精度的主要因素，提出了提高精度的合理建议。

The technical capability of non-metric digital camera get to increase continuously in resent years, because the character of its cheap, carrying convenient, easy to deal with data etc, so it have very important meaning to apply digital camera to the aspect of digital close-range photogrammetry . Non-metric digital camera and telescope of transit are connected firmly for integral whole, and adopt a fixed position equipment that can be fixed repeatedly and have high accuracy, makes so-called camera transit system. In the application of the system, This paper puts forward examined method of the inner orientation elements of digital camera firstly, and calculation formula of the opposite position relation of digital camera and transit, and calculation formula of outer orientation elements of outer photograph stands, then use indoor control field, digital photogrammetry system and space resection of single frame to examine and experiment. Aiming at position of transit center coordinate of each stand when the system is used in engineering spot, this paper put up specific serving and calculation method. For constitution of relief images of digital camera, method is to choose single image at two arbitrary stands respectively and form around relief images, then adopt indoor control field again and intersection soft of ground relief photogrammetry to evaluate precision of the system. In the end, this paper summarizes main factors that affect the system accuracy on the experience foundation, and put forward reasonable advices to improve precision.
