To add, actually a 163 km above ground camera height is corect, that is about the height at which the

Hi Haruki, Yes, from my experience, in 8-bit images, SGM and MGM tend to create artefacts or even

Hi Oleg, I have tested the new build with a SPOT 6 stereo pair using the exact model; everything

The Community Sensor Model or any other model creates a camera object that can trace rays to and from

It is advised to mapproject the images with the cameras used in your stereo processing onto the prior

This agrees with our own experience. In shadows, SfS cannot give a good result. The sfs_blend

James, Normally you have to go through ransac indeed if not all of your preprocessing data exists (

>Do you think changing this parameters will help later in the alignment? Likely not. Bundle

The sat_sim tool is not strictly speaking meant for unprojecting an image. That said, I think it

Thanks a lot for the support. The latest release of aster2asp is working fine with hdf4 format of

Jeremy, I am glad there is progress. I am not sure why one needs to set --threads 1 for mapprojecting

ASP 3.6.0 got released, for Linux, Mac Intel, and Mac Arm, as both tarballs and conda packages. More

Hi Oleg, Interesting, I will definitely try this out! When choosing the stereopairs, I did choose a

It looks that you either need to put version 4, so: VERSION_4 PINHOLE fu = 2689.859992 fv =

Could you clarify, I don't understand how using the DEM I used for mapprojection aids in

The key issue seems to be that a huge number of your interest points got removed as outliers. Maybe

I think the site http://imbrium.mit.edu/ has a lot of DEMs, likely at 20 m/pixel or so. Note that, at
