Hello,

I'm trying to run the skysat_stereo scripts.
The installation seems fine, but when I run ./skysat_triplet_pipeline.py I have this error:

xxxxx@ctsat: /src/skysat_stereo/scripts$ ./skysat_triplet_pipeline.py /media/dati/xxxxx/Skysat/TestUncalib/ /media/dati/xxxxx/Skysat/TestUncalib/RefDEM/
Traceback (most recent call last):

AttributeError: module 'pyproj' has no attribute 'network'

I don't know how to solve this problem.
Can you please help me with this issue?
Many thanks

A common question is that how much of the 3D bundle adjustment setup can be applied to improve scene2scene alignment of mono collects.

• This is not straight forward, as in-track stereo geometry (within 1 collect) is weak.
• Key idea is to fix the matchpoints in the overlapping scenes in-track with a reasonable 3D world co-ordinate and then use bundle adjustment.
• Would take some work with ASP functions to achieve this.

From the line 147 to the line 168 of the skysat_triplet_pipeline.py, is the indentation correct?

In this function, the quaternion are not used at all. You could directly use the rotation matrix from ASP, no?

Additionally, for the quaternion, you could possibly use scipy rather than a third-party library: https://docs.scipy.org/doc/scipy/reference/generated/scipy.spatial.transform.Rotation.html

Update scripts to reflect changes by ASP 3.0.0

• Main changes should be around stereo calls.
• Will change the update frame_index.csv function a bit (in devel branch)

I downloaded ASP 2.6.2 as mentioned in the README. The skysat_stereo pipeline calls cam_gen with a --parse-ecef flag, but I get the following error:

Error parsing input:
unrecognised option '--parse-ecef'

Is this a versioning error?

Work with Oleg to nail down the best parameters for exporting RPC model from the improved, self-consistent and geo-registered frame cameras.

Hi,

I was wondering if there is possibility to do same calculation using your script for PlanetScope 4-band multispectral basic data?

Best regards,
Mohammad

Right now, the triplet stereo modes expect 3 collects. It would be good to generalise it to accept n number of collects. This would help if we have a bi-stereo vs a tri-stereo, or have 2 or more triplets collected over the same spot on the ground within a reasonable timespan.

Scripts which will not change:

• skysat_overlap.py
• skysat_preprocess.py
• ba_skysat.py
• orthorectification step in skysat_orthorectify.py
• Different modes in skysat_pc_cam.py

Scripts which will change:

• skysat_stereo_cli.py
• skysat_dem_mos.py
• mosaicing steps in skysat_orthorectify.py

Hi Shashank,

Thanks for composing this great tool for processing SkySat data.

I've encountered an issue when running skysat_overlap.py. The number of images I'm processing is 966. I understand this will generate 466095 combinations. When the script is saving the bound shapefile to my predefined directory. It is extremely slow in processing and always gets stuck during the process (usually stopped at 3% - 5%). I've tried changing the directory, but the issue remained unsolved.

I'm just wondering if there is any solution in your mind that can resolve this issue?

Cheers,
Shirui

I am running into issues when trying to run the triplet pipeline script, seems like the following three additional scripts are missing
clip_raster_by_shp.py
trim_ndv.py
dem_mask.py

Hi!

I've encountered the following error after trying to run the triplet pipeline script I'm a beginner with respect to conda environments etc and programming, but I think the installation was successful.

(skysat_stereo) csir@csirstell:~/skysat/skysat_stereo/scripts$ ./skysat_triplet_pipeline.py -h
Traceback (most recent call last):

from imview import pltlib
ImportError: cannot import name 'pltlib' from 'imview' (/home/csir/miniconda3/envs/skysat_stereo/lib/python3.7/site-packages/imview/init.py).

Your feedback with this is appreciated.
Many thanks.
