摘　　要：提出了基于多视图边界自动识别的视图分离技术 ,并在此基础上实现了视图分离、视图关系确定、投影坐标系建立、投影信息提取整个过程的自动处理 ,并根据三维重建的需要 ,对所提取的投影信息进行了预处理。Based on the automatic recognition of the engineering drawings' boundary, this paper presents a new arithmetic for view recognizing. The view departing, view relationships determining, reference frame building, and the projecting information drawing can be accomplished automatically. According to the needs of reconstructing 3D Objects, the projection data are pre-processed. All of the actions are to make technique preparations for the intellective comprehend facing to engineering drawings.
