门式起重机作业环境的自适应统计滤波去噪OA
Adaptive statistical filtering denoising for the operating environment of gantry cranes
针对门式起重机智能化无人化改造过程中采集的点云图像易受到噪声干扰的问题,提出一种结合点云密度和点云体积的自适应统计滤波与拟合平面滤波的点云降噪算法.首先,基于欧氏距离将点云划分为远噪声点与近噪声点.对于远噪声点,以点云密度和点云体积为目标函数,通过自适应搜索确定统计滤波的最优参数进行滤除;对于近噪声点,则利用目标点云与拟合平面的距离加以去除.在斯坦福公开数据集上的试验表明,所提算法相较于传统半径滤波方法具有更好的去噪效果;在门式起重机实际运行过程中采集的点云数据的处理结果进一步验证了其降噪性能.该算法能有效滤除点云噪声,提升点云质量,为门式起重机智能化改造提供了可靠的点云预处理手段.
Addressing the issue of noise interference in point cloud images collected during the intelligent and unmanned transformation of gantry cranes,an adaptive statistical filtering and fitted plane filtering point cloud denoising algorithm combining point cloud density and volume is proposed.First,based on Euclidean distance,the noise points in the point cloud are divided into far-field noise points and near-field noise points.For far-field noise points,the optimal parameters of statistical filtering are determined through adaptive search,with point cloud density and volume as the objective functions for filtering.For near-field noise points,they are removed by calculating the distance between the target point cloud and the fitted plane.Experiments on the Stanford public dataset show that the proposed algorithm has better denoising performance than the traditional radius filtering method.The processing results of point cloud data collected from the actual operation of gantry cranes further verify its excellent denoising performance.This algorithm can effectively filter out point cloud noise,improve point cloud quality,and provide a reliable point cloud preprocessing method for the intelligent transformation of gantry cranes.
