地面激光扫描是一种可以快速精确获取室内外环境三维数据的有效手段。近年来激光扫描技术在古建筑保护与归档中得到了广泛的应用。建筑平面图、立面图、剖面图能够准确直观地表现出建筑的真实状态，因此平立剖面图绘制对于古建筑保护有非常重要的作用。但是，利用地面激光扫描数据进行平立剖面图的绘制需要大量的人力和时间。因此，本文提出了一种基于地面激光点云的建筑平立剖面图半自动绘制的方法，该方法包括三个部分，首先利用地面激光点云数据生成正射深度影像，然后从正射深度影像中对线特征进行提取，最后对建筑部件进行进一步的细化和完善。实验结果证实了本文提出方法的有效性，可以在平立剖面图绘制中大量的减少数据处理量和人工的参与。

Terrestrial laser scanning is an effective technology which can be used for 3D data acquisition in both indoor and outdoor scenes.Terrestrial laser scanning has been widely used in historical building preservation in recent years. Plan-view,front-view and section-view drawing can accurately describe the real status of a building.Therefore it is very important for historical building preservation.However,it will cost much human-labor and time because of inter-active operation.A method of semiautomatic drawing of plan-view,front-view and section-view of a building based on terrestrial laser scanning is proposed,which includes three procedures.Firstly,an orthographic depth image is genera-ted by using terrestrial laser scanning data.Secondly,the linear features are extracted from the orthographic depth im-age.Finally,the results are refined by describing the detailed building elements.The efficiency and effectiveness of the proposed method is examined.
