摘要
文章立足于中小企业生产部门的实际生产需求,通过分析无人机测图过程中出现的常见技术问题,对像控点的布设、大区域拼接成图和空洞补测等问题进行了研究与探讨,采用不同布网形式,对像控点的布设形式进行讨论。经过对比分析,得到性价比最优布网形式,并针对无人机航测中出现的大区域拼接及空洞问题,根据不同的情况进行处理,为常见技术问题提供了解决思路和方法,避免了中小测绘企业实际生产过程中造成的资源浪费。
Based on the actual production needs of the production departments of small and medium-sized enterprises,this paper studies and discusses the layout of image control points,large area splicing and mapping and hole supplementary survey by analyzing the common technical problems in the process of UAV mapping.Different network layout forms are used to discuss the layout forms of image control points.After comparative analysis,the optimal network layout form with cost performance is obtained,and aiming at the cavity problem in UAV aerial survey,According to different situations,it provides solutions and methods for common technical problems,and avoids the waste of resources caused by the actual production process of small and medium-sized surveying and mapping enterprises.
