I am a newbie to photogrammetry, learning & experimenting every day. It is always a pleasure to learn from an experienced user, so thanks for making these in-depth guide videos.
Honestly, even the mesh resulting from the downscaled image set looks fantastic to my eye and is absolutely sufficient for even high quality work. Great technique! For my work (gaming), i’d be happy to even downscale and decimate the mesh further! With a good normal map and the right lighting; it’ll still look beautiful!
glad to hear it! With their Epic acquisition and their price decrease, I no longer use this method and just process the photos at their full res. But glad to hear it works for you!
Unless I completely skipped past where do you tell RC to use the full res textures for texturing? And where do you tell RC to use the downscaled for 3d model?
If you haven't already figured it out. He loaded the downscale images as _gyommetry and the normal version as _textures and RC can tell the difference between the two folders and acts accordingly when processing
Not only will using the FULL resolution images take ages, especially on smartphones (and even mid range cameras) I find almost always lens blur or resampling artifacts to start stacking to the point where important features blur across twice the pixels anyway.
That is right. The difference in geo & texture quality is negligible with the photos I take with my a5100 W/ kit lens at full res vs downscaled images. There is a whole lot of lens blur even in full-res images thus downscaling the image doesn't really cause a lot of harm to me. I would like to test using a high res camera & sharp lenses and see what sort of results I could achieve.
I was just thinking if this was possible. Amazing method. PS: Honeyview and Affinity Photo can also batch downscale. Though I find Affinity less reliable, it is way faster (depending on CPU threads, it's fully parallel)
Azad Balabanian Gotcha. So the key is to find the sweet spot between scaling down, and accuracy eh? Man, this stuff is interesting. I’m using it to make reference to remodel buildings. Working great.
beautiful work! fascinating technique. By the way, do you know how to save/export a point cloud point (rcp file extention) to import in autocad? On the recent Reality Capture I can fin only export geometry files like obj. Thank you for the informative video.
Thank you, great video. I just started to use the PPI. Does it make sense to convert / downscale the original images in different file formats? For example to convert to 50% tiff? Or png? Goal is to keep price low and still have reasonable amount of details. Thanks
You can paste the directory link into the "File Name" Box and press enter, it will send your directly to the folder that you want. This has been in windows since 95. Thought you might want to know.

You can just copy the path into the "File name" and press enter to easily jump to this path 😉
a tip : you can watch movies on flixzone. Been using them for watching all kinds of movies these days.
@Jad Casen yup, been watching on Flixzone for months myself :)
@Jad Casen Definitely, I have been watching on flixzone for since november myself :D
2:43 you can copy paste the path. put it into File Name and press enter
Good to know!

This didnt work for me. I added both folders but it comes up to $3 with only 68 images from both folders.

Depending on the lens/sensor combo, yes, definitely

Yes there are quite a few ways of doing it. I just outlined one
lovely stuff
Thanks for this. Good stuff.
Is there a big accuracy hit from downscaling? Sounds interesting.
RC is really quite amazing. What fun
Andy Tanguay yes, with tricky to align datasets, downscaling can introduce problems. You just have to try and iterate

Very helpful video. Starting a business and every dollar counts before ya have paying clientele
exciting, I didn't know PPI was a thing.

Any file format supported by RC works with this method IMO, so JPEG, PNG, TIFF (among others that I dont know about). I typically use JPEG however
amazing content
What PC do you use?

good to know
Cool trick

Awesome!
Thanks a lot
Wait could I use this to make.like rocks float around my character in the real world or like a tree randomly blows up.or something
The Sony a7R II is not a DSLR. It's a mirrorless camera
stylac excellent comment

I stand corrected.
Thank you.
