General / Fiducials and DEM strange behavor

« on: September 26, 2019, 12:15:54 PM »

Hellow, I'm trying work with old photograms, when I put all fiducials ( 8 ), I obtain a good errors  but when I generate dense cloud and depth maps, the depth maps are cut.
I tried to only put 4 fiducials and the errors are worse but depth maps aren't cut  .
some one knows why this behavor, I doing somethig bad or is a metashape bug?
I'm working with version 1.5.5 bulid 9097 (64bit)

General / About accuracies

« on: February 18, 2014, 01:31:25 PM »

I've doubts about errors in PS:
In Ground control setting for "marker accuracy", I don't understand exactly its meaning I think is the RMS (x,y,z) of GPS measures.
Are the errors on Ground Control Pane the accumulate error on GPS measures and photogrametric process?
I think understand errors for profesional use is essential.
Thanks Agisoft team.

General / Problem with DEM in shadows

« on: January 31, 2014, 12:50:43 PM »

Hi, I?ve a problem with shadows when I generate dense point cloud, shadows are below the surface (10cm aprox), the surface is a basketball court and the GCP were taken with very accurate GPS (double frequency), with a higth overlap 80%-80% and low noise sensor.
Also the surface (that is smooth) seems too noisy. If I set agressive map filtering, this improve but not enough.
I?m going to try mask shadows, but is tedius. Someone knows why this happen? I hadn?t this problem with others cases on irregular surfaces.
Thanks.

General / Help with new tool classify points

« on: January 23, 2014, 06:56:38 PM »

Hello I'm testing the new tool in 1.0.0 release to classify ground points. Seems great but the trees base (at 1.5m approx) are classified like ground, seem like stumps. I tried tuning the tool parameters without succes.
Somebody know how solve this problem, thanks.
