Hi!
I'm trying out the photo input node with a set of stills to convert to point cloud for use with the match camera node. And I started thinking that my phone can shoot lidar data. Is it possible to import that data and use that for either the match camera node or the survey solver? Or is the data from the phone to bad to even consider...
I was testing out polycam and saw that you can get point cloud info from that if you want (also geometry data but maybe the matche node uses something different). Is it possible to use this data? And if so, how would you import it? 😅
Hi Jonas,
Yes, you can certainly try this out with the Survey Solver node, which will import many of the formats you can generate using Polycam for both meshes and point clouds.
You can load either raw point clouds in XYZ, XYB or PTS formats, or geometry in any format that Polycam exports such as USD, OBJ, or FBX.
The Lidar tools in the Survey Solver node have traditionally been used with highly accurate data from providers such as FARO or Leica, so the quality of results are going to depend on how noisy the dataset from your phone is.
After importing you'll need to attach your tracking points to your scanned data, and you'll probably need to specify uncertainties for the location of each point: This is needed when your survey data is noisy or doesn't contain an exact 3D location for your tracker, so I would suggest taking a look at your dataset and trying to gauge what sort of errors you have in there. You might need to set the uncertainty values to a few centimetres, depending on the type of scan your using and how it has been processed.
It would be great if you could post some screenshots and let everybody know how you're getting on!
