fov_degree,point_filter_num,max_iteration,filter_size_surf,filter_size_map,cube_side_length,这些参数是什么意思

[pcl::VoxelGrid::applyFilter] Leaf size is too small for the input dataset. Integer indices would overflow,在室内跑的时候报这个错怎么解决,应该调哪个参数

filter_size_surf,filter_size_map

室内可以把filter_size_surf,filter_size_map调小一点,一般分别为0.05, 0.15. 对于ouster或者这种点特别多的,point_filter_num可以调大,比如5~10.

这个参数下室内随机误差小了好多!

您好,想请问一下这个fov为什么是90呢?我查看了avia的手册,它的fov是70.4° (水平)× 77.2°(竖直),我如果使用mid-70(它的FOV:70.4°圆形),config文件中的fov应该改成70吗?或者更小呢?可以给我点建议吗?

Any updates on this? Can someone help me with the significance and use of these parameters
