Building modeling which used three kinds of methods ( aerial photography, build by plan, and airborne laser scanning) and its advantages and disadvantages were introduced, using a combination method of multiple data sources and variety techniques, three-dimensional modeling of building was conducted. The specific data processing of three-dimensional body and three-dimensional fine model are discussed. The three-dimensional model based on the three-dimensional laser radar technology has advantages such as high precision, wide range of applications, field work less, and more efficient, but also has difficult to deal with large amount of data, information data and data storage, fast transfer and browsing.%介绍建筑物建模常用的3种方法(航空摄影、依图而建和机载激光扫描)及其优缺点,采用多种数据源和多种技术手段相结合的方式进行建筑物三维模型构建.对三维体框模型和三维精细模型构建等具体的数据处理过程进行了论述.认为基于三维激光雷达技术制作的三维模型精度高、适用范围广、外业工作量少,省时省力,但其数据量大,信息数据的存储、快速传输及浏览等目前都还较困难.
