I run the commercial roofing division for a GC, and am looking for alternatives to paying shitloads of money for Eagleviews. I'd like to start doing my own measurements with photogrammetry and not pay Pictometry or Maxar shitloads of money. My questions is what is the best software someone has actually used, and what's my sort of minimum drone spec for this? I was hoping to use my Mini 3 Pro or one other owners has a newer Mavic. I have a Pro Controller. We are also looking at buying a Matrice 4T for thermal surveys, but some alternatives that aren't going to get ass fucked by the federal government would be appreciated.

I'm interested in the topic, and since you don't seem to be getting many replies (because the topic is a bit niche) I will offer what little I can on it.
I have heard good things about CaptureReality, and they have a demo for architectural work, and a colleague of mine has used it with drones for his work and seemed fairly happy with it.
You could add that to your list of software to consider, and it is free if you're beneath a certain income I think, like $1M maybe. Check that.
Since you are asking about something actually interesting that doesn't involve gaming hardware, brand flamewars, AI coom, pseudo-/pol/ or media piracy, on /g/, you should not expect many good answers.
Oh, possibly try /diy/ too. Not great there either but why not cast a wide net?

unironically start a thread on /diy/. they're more of a technology board than the technonolgy board these days. also less a bunch of fags.

I have tried, and no one on /diy/ actually does this for a profession.

Again, /diy/ is gay. I think I'm going to give Pix Pro a shot, unless there is a standalone program I can pirate to test. I have a Pro Controller that runs bootleg Android, so apparently Pix Pro mapping software will work. From what I've read, a Mini Pro 3's camera is good enough. I'm not trying to map 3D surfaces. Most of the shit I need images of is basically (in the literal sense) flat. We are definitely not below the income level for anything free, nor the potential service threshold. Pix Pro is like 30 in bucks a month for my needs ATM. I already do pretty extensive overheads of my projects, so some software mapping/photo interval support might be useful. It's not my money, and I have basically full autonomy to do (and spend) as I please.

To be clear, I expect to spend a shitload of money on measurement imagery. They already probably spend a five digit amount on imagery a year just on shingle jobs. Their current vendor is Eagleview (Pictometry), and they take your asshole for commercial or residential multi-family reports. Theirs are flyovers. RoofScope (Maxar) is cheaper. Theirs is satellite based. They don't say the resolution, but knowing they do glownigger work for the government and I don't have direct access to the imagery (just measurements), it's pretty accurate. My guess is they use the "good" 10cm-ish resolution images. I can't imagine they have two sets of imaging satellites, especially given they are headquartered in Denver next to Buckley (whom they definitely work for). They are cheaper; however, It would still be thousands of dollars a year. I really just want something cool. If I could use a big boy Matrice with AESA scanning radar to find hail damage on roofs, I could 100% talk them into buying something crazy. I would need to get a Part 107 license.

Are you tied to photogrammetry or can you take alternative approaches?
I'm thinking about either lidar on drones or possibly segmentation models, but I don't know much about hail damage and what it looks like, so that may not work for this. I also don't know much about what kind of output you need here. Whether it's binary there is hail damage or there isn't, or it's "there is this much hail damage" or where it is and how large each dent is or what.
There's enough information needed to work out what you could do here that it's in paid work territory, and while you're getting paid to know about it, it sounds like enough work and knowledge sharing that I would want to be paid too to keep spending time thinking about it. On the slim chance there was any person on here who did your exact same job, they'd probably be thinking the same thing.
As far as drones, if you want an American one, I think that is something /diy/ actually can help you with. The drone general there will remember what the name of that one worthwhile American drone company is, but I don't. I do remember it was considerably more expensive than the Chinese ones for the same level of capability, but I also get why you'd not want to send China detailed images of a bunch of potentially sensitive (or even if not) American buildings. The amount of data those things send back is crazy.

There is no "software", it's just autograd.
Everyone thinks the singularity will come from language models, no, the singularity happened over ten years ago with autograd. You just describe what you want and the machine gets you there. That's how they got language models to begin with. If you read any of these ML papers: LLMs, photgrametry, etc. It's all the same. They only ever describe the models forward and that's because they personally don't write software to back propagate updates, autograd just does it.
There's no software.

Skydio is one. The issue is that most of the US made drones and US made for the DoD...and priced as such. Skydio is 30k for a thermal drone. DJI Matrice 4T is 8k.

I can get know reference measurements using a laser distance finder if I needed to. I thought it uses the resolution of the camera to determine 1 pixel = whatever unit of measure?

We are getting a Matrice 4T one way one another solely for thermal surveys. It's the only way to really do them because I'm not going out to some fucking building at 4 AM or 11:00 PM to do a thermal walkthrough. Thermal drone is 10 minutes versus 1-2 hours. Measurements would just be a bonus. I would be using my Pro 3 because I have a Pro Controller running Android for now. Plus it's nice to have a show for these property management fags. They love this shit.
