摘要
针对传统的仿真雕塑三维形体测量方法存在的测量精度低的缺点,提出一种基于激光扫描仪的仿真雕塑三维形体自动测量方法。利用激光扫描仪获取仿真雕塑三维形体的整体点云数据,并采用高斯滤波法、平面投影法和双边滤波法分别对有序点云数据和散乱点云数据去噪。最后,进行精简处理,再计算仿真雕塑的三维形体数值,至此完成基于激光扫描仪的仿真雕塑三维形体自动测量方法的设计。通过对比实验,与传统的仿真雕塑三维形体测量方法作比较,实验结果表明,提出的基于激光扫描仪的仿真雕塑三维形体自动测量方法所得测量误差最大值为0.2 m3,表明其具有更高的测量精度。
Aiming at the shortcomings of low measurement accuracy of the traditional measurement method of three-dimensional shape of artificial sculpture,an automatic measurement method of three-dimensional shape of simulation sculpture based on laser scanner is proposed.Laser scanner to obtain the whole point cloud data of the three-dimensional shape of the simulation sculpture,and Gauss filtering method,plane projection method and bilateral filtering method are used to denoise the ordered point cloud data and scattered point cloud data respectively.Finally,simplify the processing,and then calculating the three-dimensional shape value of the simulation sculpture,at this point,the design of the automatic measurement method of the three-dimensional shape of the simulation sculpture based on the laser scanner is completed.Through comparative experiments,compared with the traditional three-dimensional shape measurement method of simulation sculpture,the experimental results show that the maximum measurement error obtained by the proposed automatic measurement method of three-dimensional shape sculpture simulation based on laser scanner is 0.2m3.The results indicate that the proposed automatic measurement method of three-dimensional shape sculpture simulation based on laser scanner has a higher measurement Precision.
