激光扫描技术在中国古代建筑精细测绘中的应用——以西安钟楼三维建模及精细测绘项目为例

Application of 3D Laser Scanning Technology in the Surveying and Mapping of Chinese Ancient Architecture—Take 3D Modeling and Fine Mapping of Xi'an Bell Tower Project as an Example

以西安钟楼的精细测绘与三维建模为工程实例,利用三维激光扫描技术对钟楼进行精细扫描测量,构建了准确翔实的钟楼三维模型,绘制了楼体详尽的纵横剖面、立面等二维图,为钟楼修缮和存档提供了准确的测量数据、图形、图像及模型。此外,通过该案例,详细分析了三维激光扫描技术在中国古建筑测绘应用中的技术优势与不足。

Taking the fine surveying and mapping and 3D modeling of Xi'an bell tower as an example,this paper applied the 3D laser scanning technology to carry out the fine scanning measurement of the bell tower,obtained the accurate size and shape of each structure and component of the bell tower,constructed the accurate and detailed 3D model of the bell tower.It summarized the detailed two-dimensional drawings of the vertical,horizontal sections and elevations of the building,and provided the accurate measurement for the repair and archiving of the bell tower Volume data,graphics,images and models.In addition,through this case,the advantages and disadvantages of 3D laser scanning technology in the application of Chinese ancient building mapping were analyzed in detail.
