基于TLS的异形曲面建筑立面图测绘应用研究

Research on the application of TLS-based mapping of irregular curved surface building elevation

异形曲面建筑其外立面极不规则,常规的全站仪、经纬仪测量方法进行建筑立面测量,效率低且精度不高。三维激光扫描技术是近年发展起来的一项新兴的测绘技术,可以高精度、海量、快速地获取被测对象的三维坐标,基于点云拟合出被测对象精确三维模型,已广泛应用于工程测量各个领域。以某异形曲面雕塑为例,研究了基于三维激光扫描技术对该建筑物进行立面图测绘的方法,研究结果对相关工程实施具有较强参考价值。

The facades of buildings with irregular curved surfaces are extremely irregular,and the conventional total station and theodolite measurement methods for building elevation measurement have low efficiency and low accuracy.Three-dimensional laser scanning technology is a new surveying and mapping technology developed in recent years.It can obtain the three-dimensional coordinates of the measured object with high precision,massive and fast,and can fit the accurate three-dimensional model of the measured object based on the point cloud.It has been widely used in various fields of engineering measurement.Taking a special-shaped surface sculpture as an example,this paper studies the elevation mapping method of the building based on three-dimensional laser scanning technology.The research results have strong reference value for the implementation of related engineering.
