Question : How to extract 3D feature coordinates in WGS84

[ishaniis]

Hi,

I am totally new to Opensfm, I am exploring to find out the 3D feature coordinates specifically the z coordinate. As in tracks.csv - there is no z coordinate.

Potential Approach: I thought was- merged.ply gives out - x, y,z , nz, ny, nz , r, g, b tracks.csv gives out - image_id, track_id, feature_id, x , y, r, g, b,

So if I find an x,y from the tracks.csv and run through the merged.ply after parsing it, I'll be able to find the z coordinate of the features.

I am not sure if my approach is correct or not. If not, please guide me with the same. The end goal is to find the 3D coordinates in WGS84 format.
