Point Cloud generation from Sample data

[farah-rostom98]

Hi;
I'm interested in buying the S27 camera but first i need to verify its depth threshold to do so i want to generate the point cloud from the existing sample files specifically this example

log025_on_road

I need to generate the point cloud but i need the camera extrinsic and intrinsic and i don't know what should i use the image_rect or the disparity

Can someone walk me through it what should i do? to get the 3d point cloud

Hi @farah-rostom98 That log does have a throttled pointcloud topic in it. I attached a video of how to view the point clouds.

The pointclouds logged here are clipped to 15m, so if you would like to see data beyond that range I can get you setup to regenerate point clouds from that data. Let me know what time you are interested in

Hi Matt,

Thank you so much!

Yes i would like t see the max range possible for the S27 camera, So can you get me setup to regenerate point clouds from that data.
Now would be great!
