摘　　要：在城市三维建模技术中,模型的贴图一直是建模中的一个十分重要的组成部分。虽然模型的自动贴图已经初步实现,但仍存在贴图变形或遮挡等问题,尤其是精细模型或者过于密集的模型,仍旧需要人工干预。本文以手工建模贴图方法为基础,总结了模型贴图相关技术,包括贴图的获取、处理和应用等各方面。通过在多个项目中的实践,结果表明该方法能够有效提高城市模型贴图的处理效率,并且保证贴图质量符合项目标准。Model mapping has been a very important part of modeling in 3D modeling technologs automatic mapping has been initially implemented,but there are still some problems, such aclusion. Especially for fine models or overly dense models,they still require manual interventithe mapping method is based on manual modeling method. It summed up the model mapping technology,Including the acquisition,processing and application of model mapping. Through the practice in several projects,the rthat the method can effectively improve the processing efficiency of urban mmap is in accordance with the project standard.
