梵净山保护区样地三维可视化系统设计与实现

Sample Site Monitoring of Fanjing Mountain National Nature Reserve——Design and Implementation of 3D Visual system

针对梵净山保护区样地样木测绘数据成果固化,利用率低等问题,以先进测绘技术手段为数据采集支撑,运用Hough变换算法提取了样木的胸径和树高,研究了多源样木测绘数据在管理展示中存在的主要问题。同时基于局域网基础上的C/S架构体系,通过原始创新与关键技术突破,以对象关系模式的数据技术为基础,设计了数据无缝管理及三维漫游展示的整体框架,并搭建了多源样木测绘数据管理系统,为最大限度的管理利用多源样木测绘数据提供了技术支持,对提高样木数据管控的安全性和有效性具有一定的意义。

In view of the problems of inefficient utilization of survey data in Fanjingshan Nature Reserve,the DBH(diameter at breast height)and height of sample timber were extracted by Hough transform algorithm with advanced surveying and mapping techniques as data acquisition support,and the main problems in management and display of multi-source sample timber survey data were studied.At the same time,the C/S architecture system based on LAN is mentioned,the overall framework of seamless data management and three-dimensional roaming display is designed through the original innovation and key technology breakthroughs based on the data technology of object-relational model.A multi-source sample timber mapping data management system is built to provide technical support for the maximum management and utilization of multi-source sample timber mapping data,which will have an influence on the management and control sample timber data.
