NASA Ames Stereo Pipeline (ASP)
NASA Ames Stereo Pipeline is a suite of free and open source automated geodesy and stereogrammetry tools designed for processing stereo images captured from satellites (around Earth and other planets), robotic rovers, aerial cameras, and historical images, with and without accurate camera pose information. It produces cartographic products, including digital terrain models (DTMs), ortho-projected images, 3D models, and bundle-adjusted networks of cameras. ASP’s data products are suitable for science analysis, mission planning, and public outreach.
Usage
Ames Stereo Pipeline is included in the following module:
- ames-stereo: 3.2.0
Load the module:
module load ames-stereo
You can test that Ames Stereo Pipeline is loaded successfully with
stereo -help
Running parallel_stereo can be very computationally expensive, so it should be run via batch job system. The software developers recommend reserving full nodes for Ames Stereo Pipeline.
Example batch job
#!/bin/bash
#SBATCH --output=asp.log
#SBATCH --nodes=1
#SBATCH --ntasks=40
#SBATCH --mem=50G
#SBATCH --time=5:00:00
#SBATCH --partition=small
#SBATCH --account=project_200XXXX
module load ames-stereo
parallel_stereo [options] <images> [<cameras>] <output_file_prefix>
The parallel_stereo program is the primary tool of the Ames Stereo Pipeline, it has a lot of different options described in detail in documentation.
Ames Stereo Pipeline supports also multi-node batch jobs, see its PBS and SLURM documentation for details; please notice that in Puhti, in addition to the mentioned arguments, you need to provide the --account argument and use the correct --partion-names.
