Abstract: To satisfy the need of quick development and innovative design of products，the system of integrated reverse engineering that contains the error analysis and inspection is introduced.The error analysis can inspect and restore the whole system.In the base of this，two methods for the error analysis are advanced，and their models are simpled.At the same time，a model registration algorithm is introduced.Finally，two typical cases are given to show the processes of model registration of the two different projects.

Key words: integrated reverse engineering, error analysis, model registration

摘要： 针对当前企业产品快速开发和创新设计的要求，构建了具有误差分析与检测功能的集成逆向工程系统框架。通过对所存在的误差进行分析，以便对整个系统进行实时的闭环的检测和修复。在分析系统框架的基础上，提出两个不同的误差求取方案并简化了相应的误差模型，同时给出了模型配准算法。通过两个具体案例，展示了不同方案的模型配准过程。
