最简单的一种滤波器,它的作用是过滤掉在指定维度方向上取值不在给定值域内的点。直通滤波器的实现原理如下:首先,指定一个维度以及该维度下的值域,其次,遍历点云中的每个点,判断该点在指定维度上的取值是否在值域内,删除取值不在值域内的点,最后,遍历结束,留下的点即构成滤波后的点云。直通滤波器简 … See more 与直通滤波器类似,它的作用是过滤掉点云中不满足给定条件的点,其实现原理也与直通滤波器类似,只是判断方式改变了。相比于直通滤波器,条件滤波器更加灵活,功能也更丰富,其优势主要体现在条件的定义上。我们可以依据点云 … See more 主要作用是对点云进行降采样,可以在保证点云原有几何结构基本不变的前提下减少点的数量,多用于密集型点云的预处理中,以加快后续配准、重建等操作的执行速度。体素栅格滤波器的主要 … See more 主要作用是去除稀疏离群噪点。在采集点云的过程中,由于测量噪声的影响,会引入部分离群噪点,它们在点云空间中分布稀疏。在估算点云局部特征(例如计算采样点处的法向量和曲率变化率)时,这些噪点可能导致错误的计算结果, … See more WebApr 11, 2024 · The Korea Institute of Machinery and Materials (KIMM), an institute under the jurisdiction of the Ministry of Science and ICT, has succeeded in the development of a filter-free air purifying technology to collect ultrafine particles using soft discharge and electrostatic precipitation, and clean collection plates by air spray and vacuum suction. …
