Hello everyone are new to the forum.
I am a gemetra that has been using cad for 20 years but now for passion I want to get "more" in appearance 3d and especially in tools to use.
step to the question. I often have to detect facades, which I do with the classic disto, roll and hard meter. I have a drone, a nice dji mavic 2 zoom.
I read that there is a program, true of the topoprogram (but there will be dozens) that allows the creation of a cloud of points starting from photographic relief. you can use the drone or rod and camera.
then there is a "program" of the acca, fotus, the classic photo editor.
Now, my goal is to lighten the important work, the " dream" would, fly, take pictures, return to the office, minimizing situ measurements. I have to say that often I happen to maintain facades of real estate, so drawings "simple" (not bound) 99% in 2d and useful also for the drafting of the plots to put to contest, in short, I need the classic prospectus 2d!
the problem (see also my inexperience) is this:
true that I told you, allows the creation of the infamous cloud of points;
fotus is a photo straightener.
Now, considering that I don't need a millimeter accuracy (I can also discard 5/10 cm, so much I need for computing and fading the practice, no utc will tell me that at the end of the work I raised/lowed the facades of 5 cm...!) I ask you:
then how does my classic prospectus 2d become?
I ask you this question because I was told that then I take the cloud of points, the orthogonal "turn", the shelter and get the 2d, and then.... why not use a classic photo straightener?
What gives me more (and I need) a cloud of points?
I repeat to myself it serves the classic facade to be inserted in the practice to the common and to be used for the preparation of the compute ( plaster surfaces, surface painting etc.)
thank you all, and please be clear in the answers, I am always a novice!
 
specific, I don't need a software that automatically does it, I need a 2d also recalculating that I do to my case (what so far I got from restitution of the roll, laser, hard meter!). but be careful the return from cloud of points should simplify me compared to the return of the classic relief in situ!
I want to figure out whether or not I need a cloud of points.
I make stupid example: I go to the dealer, I want a car that goes from roma to napoli, the dealer makes me see a model that goes on the moon, one that goes on mars, one that turns around the sun.... but if you take the dealership for the neck and ask him "this car, on the highway, from roma to napoli there or not?"... the half suffocated responds sadly "ehm....no...no... there is not..."
That's what I want to avoid.
Thanks again
 
software that create mesh by getting them from movies or photos perform the so-called tracking of points. after which with the process called solving recreate a 3d environment of the points themselves.
goes as long as the mesh is made only after the tracking operation of the points.
Depending on what you want to do, you may not need to have a cloud of points, but only the most characteristic points that will serve to recreate the building.

If millimeter accuracy is not so important then I recommend this software.
does not create clouds of points, but you can choose only the points that interest you and you do not need to do any straightening of the photos. great to reconstruct a facade or the entire 3d of the building starting from a series of photos taken around the building itself. other software instead create the cloud of points and do it automatically, but to have good results you have to be sorry, because they are wrong a lot and because you have no way to intervene in what they are doing.

or, in limited cases, starting from a single photo, and always in case the millimeter accuracy is not important you can proceed in this way (in the video I used 3ds max, but of course it is feasible with any other similar software.
 
This software is much more challenging than others, but far better results. Track points (from photo, or video frames) both automatically and manually. the author of the video performs manual tracking. .
 
Yes, it is possible to reconstruct the perspective also with 3ds max. It is possible to proceed with attempts or with the classic match room, however, a minimum of 5 points are required to be distributed in the 3 axes.
syntheyes is one of the many software specialized in the so-called matchmoving, that is able to reconstruct the position of the room from a single photo very easily, but it is also able to reconstruct the path of a video room by tracking points from a video.
can calculate the distortion in the photos and frames of a video and correct it and also stabilize moving videos.
also pftrack or boujou are not bad, but syntheyes provides a lot of options for tracking and tracking
 
3ds' perspective match is faster and more intuitive than syntheyes'. I never used it because it was introduced with version 14 and I instead had the 9. In the meantime, I used syntheyes.
syntheyes is phenomenal to make undistort on a single photo or even on all frames of a video when problems arise in matchmoving due to distortion in videos.

good for now I try with voodoo

has a thing uguale sketchup :eek:vanishingImmagine.webp

Did you try syntheyes too? syntheyes in my opinion has tracking correction options that I haven't found in other software of this type. It's not userfriendly, but mastery at work. I've never tried voodoo, but I've heard of it.

I only managed to do this with syntheyess. pftrack went straight to tilt because of the distortion of the video, which I always corrected with syntheyes
