| Zhoukoudian practice base is the practice base for our field geological practice, tens of thousands of students internship here,Premier Wen Jiabao inscription "cradle" for the practice base, in order to praise the practice base in the training of more than 40,000 geological workers for the country’s important role. Geology is a practical and exploratory strong science, with the development of society and economy, many typical outcrop observation, or be covered, or being developed mining, is no longer meet field observations internship conditions.2D virtual geological platform can’t intuitive concept of space is established. In order to better help in geological practice teaching, based on 3S technology, Integration of basic knowledge, basic theory and Zhoukoudian practice base data in geology, structural geology, mineral petrology. Construct a three dimensional geological gallery, assist field practice teaching, improve the teaching methods.This paper mainly studies how to take the large scale and high precision imaging method for Zhoukoudian area by the UAV remote sensing technology, and completed the surface 3D model reconstruction. Based on 2D profile completed 3D model reconstruction by 3D visualization technology. Based on the VRP of virtual reality technology to integrated express the real 3d model of the Zhoukoudian area, take a information platform can be used independently. True 3D integrated information platform make the Zhoukoudian typical practice of phenomenon and relevant knowledge can be integrated display. The Zhoukoudian area 3D model can dynamic image, intuitive, and the expression of geological unit of spatial layout and the relative relations. And integrated other 2D and 3D auxiliary information expression. It has the advantage of the student to practice area geological phenomenon has a perceptual cognition before of the field practice. After the field work, in the area of geological tectonic situation compared with their own field observations. |
