Design and Implementation of Analytical Comparison System for Airborne Navigation Database

Airborne navigation database is equipped with the distinctive characteristics of large quantity and of various types. The present article, concentrates on the problems that the traditional navigation database comparison method have that is high manpower needed and time-consuming. And then it attempts to put forward a navigation database comparison method and system design scheme on the basis of semantic segmentation. It also develops an airborne navigation database analysis and comparison system based on semantic segmentation with the help of OCR technology, Chinese word segmentation technology and comparison technology. It believes that this ensures the efficiency of navigation database and improves the integrity and accuracy in the light of the rapid query, analysis, comparison as well as periodic management of navigation database.
