Hi Everyone. I am starting a thread for discussions of the many ways people are interacting with Perseverance (and potentially other missions). These subjects are getting spread around other threads and maybe getting in the way of basic mission updates etc., so this is a place to bring this together. Feel free to contribute to it.
I am going to start by asking about panoramas - what's the best way to do this with Perseverance images, especially Navcam images from every end of drive? Phil -------------------- ... because the Solar System ain't gonna map itself.

Many people I know, including myself, encounter problems mosaicking Perseverance's NavCam images using regular softwares : AutoPano, PTGuy, Hugin, ICE, etc. (*). When it comes to include the lowest part of the images, those are so much distorted that the results are ugly (sometimes the softwares show no result at all). (*) After devignetting and color correction For me it's not really about that. For me, it's about those colours. I mean seriously, Curiosity color pictures are very homogeneous, there is little to correct between them (maybe sometime a little bit of R/B balance, exposure) but THAT'S ALL. Why Perserverance imagery is so off ? All of it, both Nav/HazCams, Mastcam or WATSON. Because, stitching pictures, remove vignetting, I can do that. But when it comes to color weirdness like this, I can't. Even with a "single" picture like those full res Navcam cut in many pieces, there is this difference between the frames. I don't why we have that but it's annoying. And I think it's not encouraging, because I read people about the "real colors" of Mars saying that Percy imagery is deceiving, too yellow, or too blue, or too something, and why so different than Curiosity ? -------------------- |
