Camera Calibration / Flatfield correction

« on: February 27, 2025, 12:27:33 PM »

Can flatfield correction be done in Agisoft, i.e. correcting for the 'vignetting' effect? Can't find any discussions about it or info in the manuals.

Feature Requests / Re: Import GCP per pixel

Hi Alexey

The lines here are for one GCP which are covered by several images, so with different X and Y pixel positions. So I want to do that for several GCPs, i.e. each GCP appears in a few images.
Format: GCP_nr Image_nr X_pix Y_pix Long Lat Alt

1   image_01   284   130   28.136518   -25.428954   1137
2   image_02   265   259   28.136518   -25.428954   1146
3   image_03   257   406   28.136518   -25.428954   1134
4   image_04   77   62   28.136518   -25.428954   1122
5   image_05   84   188   28.136518   -25.428954   1132
6   image_06   92   323   28.136518   -25.428954   1136
7   image_07   95   468   28.136518   -25.428954   1136

thanks

Hi, I am using Ver 2.0.4 and have tried the above code (both the 2015 and 2019 versions). The latest one reads only 4 parameters, so there are no pixel coordinate values used. The earlier code does read pixel coordinates but nothing happens when I run the script. I have several images in the chunk of which a few are used with known x-pixel, y-pixel, x-coord, y-coord, z-coord for the GPCPs.

General / Gradient in mosaic

« on: February 01, 2024, 05:09:15 PM »

Hi, I have a gradient across my 5x5 km aerial survey mosaic due to changing solar illumination. Can I get rid of it in some way? I am able to remove striping with the color calibration but it doesn't help for the gradient.
