摘要
针对当前两种主要城市三维模型建设方法的特点和不足,该文提出一种城市三维快速建模方法,以3D GIS技术所追求的精确数据为出发点,向虚拟现实所追求的逼真效果靠拢。该方法的主要思路和技术特点是充分利用现有城市测绘信息资源,通过研究各种模型要素的特点、开发各种人机交互辅助工具和制定相应的技术流程来实现即精确又逼真的城市三维快速建模技术方法。该方法能够提高城市三维人工建模的效率,保证城市三维模型的逼真效果,并在武汉市城市三维建模工作中得到有效应用,在城市三维建模行业中具有推广价值。
Based on data accuracy provided by 3D GIS technology, the paper put forward a method of rapid modeling the 3D city, which pursuits the realistic effect provided by virtual reality technology. It fully utilized the urban mapping information resources available, and developed a rapid method of accurate and realistic urban 3D modeling through researching the characteristics of various model elements, develo- ping various aids instrument and technical process. This method could both improve the efficiency of mod- eling and ensure the realistic effect. By the application in Wuhan urban 3D modeling, the result proved that this modeling method was simple, stable and efficient, and would be popularized in business of urban 3D modeling.
