摘　　要：介绍了逆向设计在车身产品开发中的关键技术:如何采集车身外形点云数据及创建曲面数学模型;归纳总结了汽车A级曲面的概念、技术要求及一般建模方法,以某轿车尾箱A面的设计为例阐述设计方案、曲面生成和轮廓线提取等关键技术。The key technologies of reverse design in the body product development were introduced： how to collect the body point cloud data and to create the surface mathematical model. The concepts, technical requirements, and general modeling methods of the class-A surface were presented. Taking a car＇s trunk as an example, some critical techniques in the design of the class-A surface, such as the design scheme, surface generation, and profile curve extraction, were discussed.
