Control Work in Close Range Photogrammetry

  • 摘要: 论述了近景摄影测量中实施控制的目的、分类与方法,提示可以多方法地建立物方空间坐标系,建议统一转角系统舍去地面摄影测量系统,指明控制的测定精度要求,提出建立特高精度工业控制网的理论与方法,总结了几种特殊的控制方法。

     

    Abstract: The purpose, classification, required accuracy and surveying methods of control work for close range photogrammetry have been briefly stated.The different methods for definition of space object coordinate system are also reviewed.It is suggested that the habitually practise rotation angle system for aerophotogrammetry in China should be used for the future teaching and researching work in the close range photogrammetry and the rotation angle system for terrestrial deformation photogrammetry shold be leaved out in order to avoid the confuese and reduce the amount of expands for making softwares.It has been emphasized that there are three improtant aspects in the close range control work with high accuracy using the conventional method of engineering surveying:the use of standard scale for measurement of distance between two total stations, the accurate determination of start direction line between two total stations and the influence of 2 c change during frequently focusing.A method for setting up industrial surveying control net with extra-high accuracy ±(0.05~0.20)mm is presented by the author.This kind of industrial control net is necessary for batch process of large industrial components with purposes of measurement, inspect and lofting.There are some special methods of control work in the close range photogrammetry related, including two methods presented by the author.
