Ce drone nomm\u00e9 Ingenuity. Qui embarque deux cam\u00e9ras, l&rsquo;une en noir et blanc et poss\u00e9dant une faible r\u00e9solution (640&#215;480 px mais un fort taux de rafraichissement) et l&rsquo;autre en couleurs en haute r\u00e9solution (4208&#215;3120 px). C&rsquo;est donc avec forte curiosit\u00e9 que j&rsquo;ai regard\u00e9 ce que je pouvais faire avec. Finalement, j&rsquo;ai pu trouver un bon \u00e9quilibre des couleurs, le d\u00e9vignettage (un enfer\u2026) est assez bien et la correction g\u00e9om\u00e9trique aussi. Du coup, hop, ma premi\u00e8re Carte Postale martienne, depuis le ciel ! Prise au Sol 133, et on doit \u00eatre \u00e0 une dizaine de m\u00e8tres d&rsquo;altitude, pour un vol de plusieurs centaines de m\u00e8tres.<\/p>\n<p>I had largely underestimated the potential of this drone shipped with Perseverance rover. This drone named Ingenuity. Which carry two cameras, one in black&amp;white in a low resolution (640x480px but with a good framerate) and the other one, in color, high res (4202&#215;3120 px). This is with a strong Curiosity that I looked over them, guessing what&rsquo;s what. Finally, I found a good color balance, devignetting (the hell\u2026) is pretty good, as the geometrical correction. And so, my first martian Postcard, from the sky ! Taken on Sol 133, ten meters above for a hundreds meter flight.<\/p>\n<p><a href=\"https:\/\/www.db-prods.net\/blog\/wp-content\/uploads\/2021\/07\/Sol133_IngenuityColorCam_Postcard.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-large wp-image-9452\" src=\"https:\/\/www.db-prods.net\/blog\/wp-content\/uploads\/2021\/07\/Sol133_IngenuityColorCam_Postcard-900x900.jpg\" alt=\"A picture from Ingenuity drone, showing the martian landscape from a few meters above the ground.
