General / Re: Tie Point Accuracy setting in Ground Control Settings

« on: September 20, 2014, 06:55:56 PM »

Hello everyone,

I'd like to refresh the topic about tie point accuracy.

As Alexey Pasumansky wrote:
"In fact tie point accuracy parameter effects on the weight of tie points during optimization process. Actually, changing this parameter is equal to changing all the others parameters in the opposite direction, so we do not recommend to change it except some extraordinary cases - marker/camera/scale-bar weights should be used."

Are all accuracy parameters just weights in fact?
How are they taken to calculations? In direct proportion? Inverse?
Alexey, could you elaborate on that?

Bug Reports / export edited points problem

« on: April 01, 2014, 02:39:47 AM »

Hello!

I have a problem with exporting points to the .txt file.

After building dense point cloud and a mesh I need to edit it and cut out small fractions.
When I export points to .txt, PS exports points also from the area I removed.
It is like I never delete anything despite I tried both, cutting from mesh and from dense cloud.
How can I get the xyz file from the edited area?

One more question; when I export sparse points what are the points I get? Are they coming from the point cloud (we get from alignment, not optimized with GCP) or is it decimated dense point cloud (my goal)?

I would be grateful for help.
