免像控无人机在地形图测绘中的应用

Application of UAV Image Free Control in Topographic Map Surveying

随着社会的发展和科技的进步,各种先进的测量设备也不断涌现出来。近几年来,无人机航测在测绘行业中发展非常迅速,尤其是在地形图测绘中。中小比例尺的地形图测绘基本上都采用航测的方法进行,但是免像控无人机在大比例尺地形图测绘生产过程中仍然存在很多问题。本文以泰安某地区1∶500地形图测绘项目为例,通过对航线设计、影像处理方面的分析,为提高作业效率以及地形图成果精度提供了有效的手段。

With the development of society and the progress of science and technology,various advanced measuring equipments are constantly emerging.In recent years,UAV aerial surveying has developed rapidly in surveying and mapping industry,especially in topographic mapping.Small and medium scale topographic map surveying and mapping are basically carried out by aerial surveying method,but there are still many problems in the production process of large scale topographic map surveying and mapping by image-free UAV.Taking the 1∶500 topographic map mapping project in Tai’an as an example,through the analysis of route design and image processing,this paper provides an effective means to improve the efficiency of operation and the accuracy of topographic map results.
