摘要
对于室内场景物体进行精细化模型的建立是当前三维模型重建技术的重要领域。激光点云因其具有精度高、获取速度快等优势,在三维模型建立中得到广泛的应用。本研究利用三维激光点云数据对室内场景物体进行三维模型建立,同时基于几何测量数据建立的三维模型,通过对两种方法的过程和结果进行对比,从采集时间成本、表现力、难易程度的不同证实了基于三维激光点云数据建模的有效性和高精度,最终得出使用点云数据能更好的对室内物体进行精细三维建模。
The establishment of refined models for indoor scene objects is an important area of current 3D model reconstruction techniques. Laser point cloud has been widely used in the establishment of three-dimensional model because of its advantages such as high precision and fast acquisition speed. In this study, 3D laser point cloud data was used to establish a 3D model of an indoor scene object, and a 3D model was established based on geometric measurement data. By comparing the process and results of the two methods, the effectiveness and high accuracy of 3D laser point cloud data modeling are verified from the differences in acquisition time cost, expressiveness, and difficulty level. Finally, the use of point cloud data can be obtained. Better fine 3D modeling of indoor objects.
