基于DPC与TDOM绘制大比例尺地形图可行性研究

Feasibility Study on Making Large Scale Topographic Map Based on DPC and TDOM Technology

近年来,摄影测量呈现出前所未有的发展新态势,传统摄影测量技术面临着深度变革,提出了基于DPC与TDOM绘制地形图,目前该技术还处于研究阶段,山东省地质测绘院采用低空无人机摄影测量技术进行了探索实验。该文基于1∶500比例尺地形图测绘项目,对试验区进行了低空无人机摄影、影像处理,利用DPC与TDOM绘制1∶500比例尺地形图。经精度检核,证明该技术可行。

In recent years,photogrammetry has been developing.Traditional photogrammetry technology is facing the reform.The feasibility for making topographic map based on DPC and TDOM technology has been put forward.At present.The technology is still in research stage at present.The technology experiment has carried on the exploration by Shandong Geological Surveying Institute by using low-altitude uav photogrammetry technology.Based on topographic map surveying and mapping project with the scale of 1∶500,low-altitude uav photography,image processing has been carried out in experimental area,and topographic map with the scale of 1∶500 has been made by using DPC and TDOM technology.The feasibility of the technology has been determined through precision.
