Ce sol-ci, il a command\u00e9 au rover de prendre une s\u00e9rie de clich\u00e9s du rover lui-m\u00eame, dans sa globalit\u00e9, peu avant que celui-ci ne commence la longue proc\u00e9dure d&rsquo;int\u00e9gration Mastcam34. Le but ? Pouvoir compl\u00e9ter ce panorama comme tant d&rsquo;autres qui n&rsquo;int\u00e8grent pas le rover dans la sc\u00e8ne. Et je suis parvenue \u00e0 faire un r\u00e9sultat jamais obtenu auparavant : un panorama r\u00e9ellement complet et couleurs !<br \/>\nLe travail ne fut pas simple : tout d&rsquo;abord les images Mastcam ne furent pas envoy\u00e9es en couleur mais en noir et blanc avec matrice de Bayer. Ensuite, il me fallait faire correspondre images Mastcam et images Navcam de fa\u00e7on \u00e0 ce qu&rsquo;elles puissent bien se compl\u00e9ter. Apr\u00e8s, la mise en couleur de la sc\u00e8ne Navcam.

And what a view ! It&rsquo;s simple : it&rsquo;s one of the most spectacular panorama ever recorded.<\/em><br \/>\n<em>And I wanted to do things right. With the very helpful initiative of <a href=\"https:\/\/www.dougellison.com\" target=\"_blank\" rel=\"noopener\">Doug Ellison<\/a>, in charge of programming Navcam panorama at JPL, the dream was reachable. This sol, he commands the rover to take a set of pictures of the rover itself, full body, just right before a full Mastcam34 integration. The goal ? To complete this panorama because most of them don&rsquo;t include the rover deck. And I did manage to have a result never obtain before : a true complet color panorama !<\/em><br \/>\n<em>The process was not simple : first, Mastcam pictures weren&rsquo;t downlinked in colors but in greyscaled-jpeged-Bayered form. Then, I had to match Mastcam and Navcam images in order to have a smooth transition between them. After, the colorization of the Navcam scenery.
