Hi I'm completely new to 3D Zephyr

[JonsBack]

i hope I'm not making some horrendous mistake by posting here but I'd like some input / help with this problem I'm having.

So I've uploaded 44 images; making sure they were all cropped to the same size and had the same brightness. Yet, Zephyr deemed that only 14 of them were usable. When I chose "Human Body" for the category, should I have chosen "Aerial" or "Close Range"? Maybe it's because I took my images from a video? Or maybe in the Photos Selection Page of Project Wizard, I should have chosen "Import Pictures from Video"?

Whatever the case, I'd be happy to hear some suggestions. One link is for the video, the other is for the images I took.

Im pretty sure you never want to crop or edit the images as zephyr will have a much tougher time constructing the model

Also aerial would only be good for drone type fly over projects

Hi JonsBack,

no worries! Every question is welcome

From your screenshot it looks you cropped out the rotating helm, is that what you want to reconstruct?

Copyright discussion aside, those images are too small while there may be some way to orient them, zephyr works best with bigger images. So while it is possible to orient them, i wouldn't expect a too good mesh out of those screenshot.

The "import from video" function simply splits a video (mp4, mpeg, etc) into jpgs or pngs. For those kind of images close range is the correct choice as it works better when the images are from the same distance /
have the same focal lenght.

As cguy pointed out, cropped images are usually a no-no so that is also another challenge you have to deal with. You could potentially get something out of it if you are cropping them the same exact size since it is a virtual camera, it would result with the same virtual intrinsics parameters.

I would usually ask you for the dataset, but since you're extracting frame from a video with a standard youtube license, i'm afraid i can't help your processing it unless you're the owner or permission from the owner. However, feel free to ask anything anytime and if you have your own dataset i will be happy to help you processing it

Ah what a shame that I can't do anything with those images! My plan was to get a 3D model of the helmet, load it into blender, convert it into an STL and use this program called Pepakura that allows me to make templates out of it. From there I could assemble it in real life and it'd look pretty cool.

Unfortunately, Ubisoft hasn't released any character models and ripping models from the game is another realm of difficulty and doesn't work with some games. I had hope for this method because the alternatives are unknown or just suck. I guess I could just measure the helmet and what degrees it curves at or whatever.

Oh and I didn't even realize I was potentially stepping on a big video game publisher's toes by doing this, I really don't intend to use this maliciously.

Thank you for your responses.

No worries

I think that if you do it for your own personal use it's still in the fair use realm, but by policy we can not host that material on our servers as that would not be personal use for us.

You could try taking screenshots in game, although, to be fair, there are software that can rip 3D model directly from computer memory which is probably a better way to obtain it. I did with screenshot for fun a while back to recreate the car model of my rocket league car ( https://sketchfab.com/models/f4cbf21...1b3d8d071f4c84 ) so if you don't need 100% accuracy it is something doable.
