三维激光扫描技术在快速建模中的研究与应用

Application and Research of Three-dimensional Laser Scanning Technology in Rapid Modeling

三维激光扫描技术是一种先进的全自动、高精度立体扫描技术。作为一项新的数据获取手段,三维激光扫描技术以非接触方式获取物体的点云数据。通过对点云数据进行预处理、拼接、融合等处理来快速建立建筑物的三维模型。不用对实物表面进行任何处理,便于从实物中采集目标的真实数据,所获得的模型具有较高的准确性和更强的真实感,可使视觉更加客观真实。

Three-dimensional laser scanning technology is an advanced automatic and high-precision three-dimensional scanning technology. As a new data acquisition method,three-dimensional laser scanning technology obtains point cloud data of objects in a noncontact way. And through the pre-processing,splicing and fusion of point cloud data,the three-dimensional model of the building can be quickly established. It is not necessary to deal with the surface of the object,so it is easy to collect the real data of the object from the object,so the obtained model has a higher accuracy and a stronger sense of reality,which is conducive to a more objective and realistic vision.
