【摘要】 基于非量测相机的近景摄影测量系统是将非量测数码相机通过特制连接件安装在全站仪上，所构成的一个刚体系统。在本文中详细介绍了该系统的硬件组成及相互关系,由于量测相机价格昂贵，所以非量测相机在近景摄影测量中被广泛的应用，因而对于近景摄影测量中非量测相机的检校一直是一项很重要的工作，检校工作的正确性与准确性对于利用非量测相机进行摄影测量工作具有极其重要的意义，在本文中，将通过一系列的实验对于检校过程进行说明。本系统由全站仪、数码相机组成，成本较低，通过连接件将两者联系起来，在工作过程中利用全站仪做控制测量，利用非量测数码相机拍摄测区照片，然后利用像片和控制成果在数字摄影测量系统中进行相关的测绘工作。将全站仪与相机相连接，可以利用全站仪的读数控制摄影方向，对于保证相邻像片间的重叠度有重要作用；另一方面，在前期试验过程中，如果检校出相机中心与全站仪中心的精确位置关系，在不拆卸系统的情况下，可以保证两者的位置关系的稳定性，在野外工作过程中，只需要求得摄站点坐标、摄站仪器高以及观测的水平角度，然后再通过两者的位置关系数值就可以推算出摄影瞬间照片的外方位元素。本文将对此系统的精度进行评价、分析，并就所得出的精度与相关的测绘标准以及一些应用实例的精度要求进行对比，从而得出本系统在工程应用中的工作范围及可行性方案。更多还原

【Abstract】 The non-metric camera based close Range Photogrammetry is a rigid system whichInsta lled the non-metric digital camera on total station by a specia l connector . This paperdescribes the hardware and the ralationships of the system. The non-metric camera has beenwidely used in close-ra nge photogrammetry because of the high price of metric cameras. Thusthe calibration of non-metric camera has always been a very important task. The correctnessand accuracy of calibration is extremely important to photogrammetry work which used thenon-metric camera. This article will expla in the process of calibration through a series ofexperiments.The system consists of total station and digital cameras , thus it is lower cost. The twoparts contact by connector. In the work, the total station is used as a control measure and thenon-metric digital camera is used to shoot the survey area. And then the photograph andcontrol results are used to do the surveying and mapping work in Digital PhotogrammetrySystem. In the pre-calibration process, if the accurate position relationship between cameracenter and total station center can be calibrated, the stability of relations between the twolocations can be guara nteed in the case of ma inta ining the system. In the course of field work,the exterior orientation elements of the insta nt photo can be calculated by the positionrelationship between the photo sites coordinate and the level angle of the observation. Thepaper evaluated the accuracy of this system, and compared it with the accuracy of mappingstandards and some applica tion examples , thus obtained the applica tion area and the feasibilitypla n of the system in engineering applica tions .更多还原
