what is the largest cloud size that your PCL application can handle?

Hello,

 

I am developing a PCL-based application. It often has to handle large point clouds. Many modules are involved, including filter, segmentation, surface, visualization. Current limit is at about 2,000,000 points on a 32Bit Windows system. After that, the program stops due to a bad_alloc error.

 

What are the largest cloud sizes on your systems?

 

Philipp

Hi,
How many points can PCL handle. I mean max point size limit?

PCL uses std::vector to store everything, so it is really only limited by the amount of space available in RAM / swap space of your machine.  To the best of my knowledge, there are no hard-coded limits anywhere.

Indices are being stored as 32bit signed integers in a number of classes :<

You can start having surprises after 2^31 points.


Cheers

I surely hope not :) You are the ones using the library in real scenarios and that's input I can't provide.


Just for the reference, this is the biggest reported size file so far: 184685009 vertices.

Is there any way to load and process the data faster? A file which is of size 300MB takes more time to load and process.

Is the file in binary or ASCII format ?

 

And do you really expect large and small clouds to require the same amount of processing time ?

The input file is .las format

The LAS format is binary, so there is little chance that a speedup is possible.

 

And the processing time has nothing to do with the file format.
