Tracks on Mars

by JackDesBwa 2019-09-11 06:54:28

The Curiosity rover currently on Mars planet sends photographs of its cameras on a regular basis. They are automatically added to a public repository when they arrive. Of course, they are often of low interest for the wide public.
Due to low bandwidth and low signal, a lot are lost and most are transmitted in low definition, low resolution, low quantification, black and white. Most cameras are b/w anyway. There are several stereoscopic cameras onboard and sometimes the two parts of the pair manage to come back to Earth.
I found two corresponding shots with quite interesting photographic content. They were taken on SOL2449, which converted to Earth time is 2019-06-27. The bare photographs can be found at https://mars.nasa.gov/msl/multimedia/raw/#/?slide=2449 and are credited to NASA/JPL-Caltech without copyright. The cameras are separated by approximately 42cm, with f/12 aperture and a 37mm-equivalent lens (45° field of view).
There is quite work to go from bare images to such a stereo picture, mainly because of the quantification and levels mismatch. However the longest part is definitely to find matching images in the first place.
