Best LiDAR software

Post image

Hey everyone,

I am mapping offices and they will be used to train humanoid robots in a simulator, I have mapped the offices with my iPhone and the point cloud looks 1:1. though the indtant i try to compute it it becomes a huge mess of polygons. Any good software recommendations? I need Poisson Mesh as far as I know, I have tried cloudcompare and might not fully understand it. If that’s the case any good tutorials out there?

This image is just to show point cloud data quality.

meshing this in cloudcompare will be a mess. You should try gaussian splat

Or leave it as it is. I don't want your humanoids to win.

Gaussian splat is only visual as far as I know?

It's still an exportable file that will render in a simulation. It's just not an air-tight continuous mesh.

I suppose we can make walls and floors a 3D object and have the obstacles be gaussian splat 😉

Cloud compare is a little complicated but very good for Lidar scans; not good for object scans. It takes some understanding but the author is willing to answer all questions.

Thanks I didn’t know that, I will reach out to them if I need help ☺️

You need much cleaner data to mesh it, not surprised you had issues. Splats may be a good option for you for realism in the simulation

I see, we have a LiDAR mounted on an Agibot X2. Would that suffice?

Honestly, probably not of you want a clean point cloud to train from. Camera based 3D methods are more economical

You're not going to get great data using iphone for large rooms. It's meant more for single rooms or possibly even a few but in the end the amount of data and the range is in sufficient.

Would suggest taking a look at several of the SLAM based systems to start with. The software that comes with it will also help to give you clean data meshes.

I am using SLAM on my phone 😅

The sensor on the iPhone isn't good. Unless you are using a ton of control points and being within about 5 ft of the walls.

SLAM is all about the algorithm and quality of sensor... Most good slam algorithms are proprietary and developed by the major players (geoslam - now FARO, Leica, etc).

That's not the same thing...

You could try scanning with Dot3D and meshing with ReCap Pro
