近景摄影测定冷却塔倾斜变形的精度分析

Precision Estimation for Measuring the Volume of Oblique Deformation of A Coaling-tower by Close. Range Photogrammetry

本文应用近景摄影测量技术，使用单片摄影的方法测定了焦作电厂１号冷却塔的倾斜变形情况．文中详细介绍了具体的实施方法．并对测量成果所达到的精度作了分析和比较；计算结果表明，在无像控点参与解算的情况下仍达到了较高的精度．

This paper introduces the surveys on the oblique deformation of No.1 coaling-tower in Jiaozuo Power Plant by means of single image photogrammetry and close range photogrammetry technique. The author explains the surveying procedure in detail, analysing and estimating the available accuracy of the measurement. The evaluation concludes that it is still high-accuracy without using the photo controls.
