地面摄影经纬仪(以下简称地摄仪)是在地面上进行摄影测量的外业仪器。地面摄影测量可根据所摄取的地物底片,在室内利用精密绘图仪绘制地形图来确定大地坐标。因此它可以把大量的野外测绘工作搬进室内完成,它比起航空摄影测量作业简单、经济。适用于山区小面积大比例测量。地摄仪摄影物镜的焦距、畸变以及像主点是它的内方位元素。如何准确地测定这些元素乃是目前生产中的关键。本文给出了适合生产中测试内方位元素的计算公式,并对测试中产生的误差进行了初步分析。
Terrestrial photographic theodolite (hereinafter referred to as photogrammetry) is a field instrument for photogrammetry on the ground. Ground photogrammetry can be based on the location of the film taken in the indoor use of precision plotter to draw the topographic map to determine the coordinates of the earth. So it can move a large number of field mapping work done indoors, it is easier than the aerial photogrammetry operations, and economy. For a large area of mountainous area measurement. Focal photographic lens focal length, distortion and like the main point is its internal orientation element. How to accurately determine these elements is the key to the current production. In this paper, the calculation formula for the azimuth elements in production is given, and the errors produced in the test are preliminarily analyzed.
