辐射计算法标定航空像片样地—在千岛湖封山育林地区调查中的应用

Application of Radiation Computing Method to Demarcate Aerophoto Plot in Qiandao Lake's Region

本文采用标定航空像片样地新方法,解决了像主点落水或选刺像主点困难的难题。此法效率高,点位精度好,用单张像片标定样地,避免了立体观察辐射交会;同时在检查样地时,容易判定移位原因,便于纠正。因此,在千岛湖地区的调查研究中,此法显得简便、易行,是效率高的好方法。

The new method demarcating aerophoto plot in forest survey in Qiandao Lake's region is efficient and precision. The problem of punctuating photograph's principal point is solved, avoiding radiative intersection through atereoscopic observation. It is easy to determine the cause of position movement and to correct it while examining the plot.
