[request] Performance of pcl::KdTreeFLANN

[jujimeizuo]

In the kdtree module, has the performance comparison between pcl::KdTreeFLANN and libnabo passed the benchmark test? Because the performance of libnabo is said to be good, I would like to ask.

[mvieth]

At the moment, PCL does not use or support libnabo, and there are currently no plans to change this. We have not done any performance comparison between FLANN and libnabo.

For reference, there is #5299, which looks into using nanoflann as an alternative as well or FLANN CUDA.

Thank you, I mainly want to know who has the best performance among all kdtrees. And get the result through benchmark.
