Open3D常用点云滤波

在点云处理中,过密的点云需要下采样,离群点和噪声点需要去除,通过滤波的方法,可以抽稀点云,把离群点去除,以便进行下一步处理open3d中,很多滤波器已经被封装成了对应的方法(源码是C++)1.直通滤波直通滤波过滤指定维度(x,y,z)内,指定值域外的点#定义直通滤波函数defpass_through(cloud,limit_min=0,limit_max=10,filter_value_name="z"):points=np.asarray(cloud.points)iffilter_value_name=="x":ind=np.where((points[:,0]>=limit_min)&(
