一种基于影像匹配技术的等高线生产工艺方法

Contour Production Process Method Based on Image Matching Technology

等高线是基础地理信息产品的基本组成要素,在实际生产中一般通过航测内业方法获得。本文通过影像匹配技术对该传统等高线生产工艺进行改进,优化后的工艺流程能够提高作业效率,并降低作业强度。经过实践验证,这种快速等高线生产工艺可操作性强,产品质量符合测绘行业标准,对提升测绘产品服务能力具有实践指导意义。

Contour lines are the basic component of geographic information product, which are usually obtained by aer- ial photogrammetry in actual production. In this paper, the technology of image matching is used to improve the tradi- tional contour line production process. The optimized process can improve the operation efficiency and reduce the op- eration intensity. Through practical verification, this rapid contour production process is highly operational, and the product quality conforms to the surveying and mapping industry standards. It has practical guiding significance for im- proving the service ability of Surveying and mapping products.
