I have met an issue, I would like retrieve the object area from point cloud data, (x y z) format.
The problem is the object is an 'open' surface. ( a twisted paper for example )
I used convex hull 3 to calculate the outlier facets area, then accumulate them as the surface area......
but it is almost 2~3 times than true value.
I think the convex hull built a 'closed' surface and some facets do not exist. how can I remove those facets?
Please give me some keys.....Thank you very much!!!
