Research on Merging Method for Survey Area of No Photo Control Points

doi:10.13474/j.cnki.11-2246.2018.0312

Abstract

Abstract: In view of the inaccurate orientation in aerial regulation of various observation areas without photo control points in the process of large-scale UAV oblique photogrammetry due to terrain fluctuation and other reasons,this paper proposes a matching method to divide different no photo control points areas on the basis of the height differences of air route datum between DEMs in contiguous observation areas.This method has a great advantage over the traditional manual matching division in efficiency and accuracy,which is referential and applicable to the data processing of large-scale aerophotography in mountainous areas.

Key words: DEM, oblique photography, no photo control points, survey area merging
