Q1:How to get my footprint data?
I want to obtain footprint data from my own testing data. In a large scene, such as in Example 1, the point cloud data contains trees and other debris, but the footprint data in Example 1 has already excluded debris and only includes the footprints of the building that needs to be reconstructed. I tried using the function generate_ Polygon, but later it was discovered that only the footprints of individual buildings could be extracted.It doesn't work.So how do I obtain footprint data from my own test data?
Q2:Why does coordinate transformation occur?
In my separate building reconstruction process, as in Example 2, I found that the coordinate values of the reconstruction results changed, for example, the x coordinate of the input point was between 400-500 and the y coordinate was between 1000-1100. But the x、y coordinates of the reconstructed result are completely out of this range, what caused this. Is there a coordinate transformation in which part of the code?
