💖 PCL_OPENNI_OCTREE_COMPRESSION 💖

okay bestie, gather round, because this is a User Commands page and it's giving "tiny tool, big job" energy. It's pcl_openni_octree_compression, and it lives in section 1 of the manual, so it's a command you just... run. no cap. 🫶

✨ NAME ✨

pcl_openni_octree_compression — literally just pcl_openni_octree_compression, that's the whole name, she's not hiding anything 💅

🌸 DESCRIPTION 🌸

so first thing first: please specify a compression mode. The tool is standing there with its little hand out like "ma'am... which mode". That's the vibe. Please specify compression mode.. — the double dot is canon, I don't make the rules.

PCL octree point cloud compression</puruple> — that's what we're doing here. Octree. Point cloud. Compression. Iconic trio honestly.

Here's the usage, verbatim, no notes:

usage: ./pcl_openni_octree_compression [mode] [profile] [parameters]

🎀 I/O 🎀

  • -f file — the file name. that's it. that's the whole job. she's a name-giver.

🦋 file compression mode 🦋

  • -x — encode the point cloud stream to a file. writing mode, main character energy ✨
  • -d — decode from a file and display the point cloud stream. reading mode, she's showing off 💖

🌈 network streaming mode 🌈

  • -s — start server on localhost. host era begins 👑
  • -c host — connect to server and display the decoded cloud stream. guest era begins 🧚

💜 optional compression profile 💜

  • -p profile — select the compression profile, and here are your six flavours, lowkey a whole menu:
    • "lowC" — Low resolution with color
    • "lowNC" — Low resolution without color
    • "medC" — Medium resolution with color
    • "medNC" — Medium resolution without color
    • "highC" — High resolution with color
    • "highNC" — High resolution without color
fr fr pick your fighter. "C" means color, "NC" means no color, and the resolution is right there in the name. iykyk 💅

🍓 optional compression parameters 🍓

  • -r prec — point precision Hz
  • -o prec — octree voxel size
  • -v — enable voxel-grid downsampling
  • -a — enable color coding
  • -i rate — i-frame rate
  • -b bits — bits per color component
  • -t — output statistics. she's reporting back 📊
  • -e — show the input cloud during encoding. yes bestie we're watching it happen 👀
  • -minmax min-max — set the PassThrough min-max cutting values (default: 0-3.0)
  • -field X — set the PassThrough field/dimension X to filter data on (default: 'z')

⭐ example ⭐

here's the moment you've all been waiting for, a real live command:

./pcl_openni_octree_compression -x -p highC -t -f pc_compressed.pcc

encode (-x), high resolution with color (-p highC), gimme stats (-t), and dump it in pc_compressed.pcc (-f). ate. 🔥

and that's the whole page bestie, you're free to go compress some clouds 🦋✨

okay bye, this was pcl_openni_octree_compression version 1.7.1, from May 2014, and it came to you straight from the Debian side of the internet. periodt. 💅🎀💜
