遥感数字图像分析与应用课程虚拟仿真在线实验教学系统设计

Design of Virtual Simulation Online Experimental Teaching System for Remote Sensing Digital Image Analysis and Application Course

遥感数字图像分析与应用是高校地理信息科学专业的核心课程,实验教学是该课程教学过程中的重要环节。针对传统的实验教学过程中存在的理论抽象、算法复杂、教学过程讲解困难等问题,将虚拟仿真在线实验教学引入传统实验教学",虚""实"有机结合,充分调动学生自主学习的积极性与创造性。虚拟仿真在线实验教学采用演示模式与自主实验模式,以三维动画方式,引导学生完成并掌握遥感图像成像原理、大气衰减及图像处理技术与相关算法实验,培养学生设计及分析综合实验能力,为遥感图像综合应用储备知识技能。

Remote Sensing Digital Image Analysis and Application is the core course of geographic information science in universities,and experimental teaching is an important part of the course.For the problems of abstract theory,complex algorithm and difficult explanation in traditional experiment teaching process,online experiment teaching of virtual simulation is introduced into traditional experiment teaching,which organically combines the virtual with the real practice and fully mobilizes students’initiative and creativity in independent learning.By adopting demonstration model and autonomous experiment model,and through three-dimensional animation model,online experiment teaching of virtual simulation guides students to complete and master the experiments about the principle of remote sensing image imaging,technology and related algorithm of atmospheric attenuation and image processing.It also can train students to design and analyze comprehensive experiment ability,and gain the knowledge and technology for remote sensing image comprehensive application.
