Sparce and dense cloud export

[pbourke]

If I export the sparce point cloud I get a sensible result, first few lines look like this

0.4533 0.8372 -2.5517 82 59 54
0.4743 0.8431 -2.5234 142 125 119
0.4728 0.8505 -2.5284 141 124 117
0.4890 0.8367 -2.5219 146 137 133
0.0657 0.8378 -2.6840 205 197 184
-0.0097 0.8394 -2.7019 198 188 175
etc etc

But if I export the dense point cloud, same model, I get seemingly incorrect values for z axis, first few lines

-0.8732 1.4543 -6356755.8168
-0.8827 1.4062 -6356755.8348
-0.8887 1.4715 -6356755.8116
-0.8870 1.4534 -6356755.8185
-0.8990 1.4234 -6356755.8288
-0.9016 1.4706 -6356755.8125
-0.9136 1.4397 -6356755.8219
-0.9127 1.4105 -6356755.8305
etc etc

What might be causing this?

Hi Paul,
are the sparse and dense cloud in the same position in Metashape when toggling between the views? Are the export settings identical?

I've just tested the export of sparse and dense cloud on an unreferenced project and after loading both into CloudCompare, they are in the same position. Metashape 1.6.4.
Cheers.

Hello Paul,

Looks like a coordinate system issue.

Are you using the same coordinate system selection for both exports? And if the dense cloud instance in the chunk's contents of the Workspace pane has "Lock Transform" option enabled?
