since I have been having problems finding a program to use for something of this sort, this is great! going to give it a shot. thanks for explaining so well.
Thank you very much! Very nice walk-through! Glad I found your channel! 🙂
Glad you enjoyed the walk-through! Its actually fun building little models this way! 😀
Awesome video. Just video I watched. Will subscribe
Welcome aboard! Glad the video was helpful to you.
Great video Rich! Are you able to also add additional photos taken from the ground in addition to the video for the alignment process?
I haven't tried adding more images from the ground. In theory you should be able to combine different flights together.
Hi Rich thanks ever so much for putting these videos online I’ve been following your channel for a number of years and I’ve seen many parallel interests that I share with you and I can wish you nothing but current and future happiness and success all the very best from Chris
Glad to have you following along with the channel!
Hello!
Congratulations for the video, it was very good and very well explained.
Would you happen to inform the following characteristics of the video and processing?
Video:
1- What gimbal angle did you use?
2- Did you use the video format as wide or 4:3?
Processing:
3- Alignment, advanced.
4- Dense cloud, advanced.
5- Mesh, advanced.
6- Texture, advanced.
Thank you very much!!
I can't remember the gimbal pitch used, been a little while. Went with the wide video. Sorry to say I don't remember all of my settings in Metashape for this one, it's been a while since I produced the video, and when I was done with the video I deleted the project.
After aligning photos & going back to workflow, “Build Dense Cloud” isn’t an option. Thoughts?
Awesome video and tutorial! What do you export it to so that it's viewable in 3d mode for a client?
I show my 3D models on Sketchfab. You can upload your point cloud or model to Sketchfab, and then share it / embed it on your own website.
Would this technique also work for video taken from a typical grid pattern flight? Can you choose the image selection rate -- roughly how many minutes of video produced 60 images? Thanks for a very interesting video.
Yes, absolutely, this would work. In the Metashape video import you can vary the frames, and you should test it out as I can remember which setting makes more images, and which makes fewer. Be sure to make a folder for the Video Import images to be stored. I forgot one time and had several hundred PNGs saved to my desktop. Whoops. 😀
dzięki
Hi Rich, the video is very interesting and very well explained!!! Please, could you tell me how to generate an output of the 3D model to be able to view it in a browser and in Autocad? Thank you so much!!! Horacio
There are many outputs from Metashape. I usually use a PLY file, and upload it to Sketchfab (a service that hosts 360 models) so my clients can the model. There are outputs for CAD as well. If you're into 3D modeling there are many tools out there beyond just drone models.
Great work. Could you export it to a 3d software like blender or unreal engine?
I have worked with models in Blender, but I have not done any work with Unreal engine. I use Metashape and WebODM for generating models, and the big part for Blender would be making sure I've exported the models in a format Blender will be happy with.
nice job. How would it cope with a 'fish eye' distorted camera footage (like from a gopro) ? would you use the raw video, or would you need to 'de-fisheye' it first ?
I haven't tried it with a fish eye like the GoPro. Could be an interesting experiment to see how Metashape handles it. Here's one thing I do know. Metashape is more than a program for drone modeling. People have been doing photogrammetry before drones hit the market place. I've seen some amazing models generated with ground based cameras as well. So I wonder how wide or distorted the images could be going into Metashape. Would be an interesting experiment to walk around the home with a GoPro and see what gets generated.
@@AZ-Drone Well, I flew and filmed with a RunCam Orange 5 (about same fish-eyeness factor, as a cheap GoPro equivalents). The 3d model got generated. A bit skewed, but that may have to be fixed by tweaks in the Metashape. Still, quite impressive, for the little effort required :) Next I may try to program area scan, to fly in parallel lines. See what that produces.
What's up with the transparent circle in the middle of the frame? Is shooting in 5.4K overkill(Air2S)? Any requirements with frame rate/shutter speed? I'm going to try this...I like it a lot. Thanks!
When I did this one I was just shooting HD, 60fps. I kept the speed a little lower, and I probably could have done it a little faster.
Very impressive! Is all the processing you show in this video achieved with a Mac Studio (I'm asking just to have a reference)? Was this example entirely done with MetashapePro Standard edition?
This processing was done on a Mac Studio. I also just tested this morning on my old iMac that has the Standard Edition of Metashape as well. You can import from video to the standard version. Just don't try it on my old iMac as it is a "little slow". Running this model on the Mac Studio? Yeah, nice and quick!!!
@@AZ-Drone Good to know, my iMac CPU is a Quad-Core Intel i5 from 2015, I can see that it will be too slow for this, hope to upgrade to Mac Studio M2 next year!
@@ricci.hidalgo Just to let you know...I also have a Mac Mini M1, and it has surprised me with how speedy and stable it is. Before I got the studio I was using the mini for smaller models as well.
@@AZ-Drone Yes I know, I have a MacBook Air M1 that has also very good performance on FCP, but still aiming to the Mac Studio for other reasons.
I had a request to film a road for evaluation purposes and i tried to import it n follow steps you showed but the result was horrible n i wonder if there is something that i missed n if i do need to take a reference ground control points as well if i have a multiple videos so i can work with every single video in a chunk n stitch them together for final result
In the case of documenting a road I'd probably lean toward doing a model with Drone Harmony or Map Pilot Pro to generate an orthomosaic model. Unlike orbiting a house where we have a point of interest, a road probably wouldn't come across well. How long is this section of roadway?
Can you use this software to get dimensions? Like calculating the width of the roof?
I think once you turn it into a 3d model, if you know a few dimensions of something in the shot (Truck length, door width, etc) then you can scale the whole thing based on that
Hi, thanx for your video. One question : did you program the flight or you flew manually ?
The video for this one was pre-planned. Just a quick little waypoint series around the site.
@@AZ-Drone thanx. With third part (litchi) or DJI software ?
@@MDC.42 I used Litchi on this one.
@@AZ-Drone thanx. I didn’t understand that important point in the video :-(
What is KPRC? You mean the television station? Like, your drone was close to a transmission tower?
KPRC is our regional airport here in Prescott. If you pop over to Skyvector.com you can see aeronautical charts across the US. And if you use their search tool for KPRC you'll see all the relevant information about the airport. Also, Embry Riddle Aeronautical University is here is Prescott, so we have a lot of student flight traffic here.
I downloaded this app to my MAC Book Pro... But I am having huge problems.... It crashes constantly... I haven't been successful with one model yet.... Is there a setting or preference you may have some insight into that may need to be changed? My MAC is 7+ years old now so that might have an impact... Other software I am trying (learning with) WebODM, DroneDeploy, SkyBrowse, doesn't seem to have this issue so I am curious if I may have missed something.
Sorry to hear its crashing on you. I have used it on a 2017 iMac, and been able to produce small models (turning everything else off). But super slow. On my Mac Studio M1 with 32GB of ram it works very well. But on a 7+ year old Mac? Not sure it will work very well unfortunately.
Have you ever tried to pull a Metashape model into a drafting software like Autodesk Revit? I work at an Arch/Engr firm and am trying to think of ways that I could implement my drone interest into my day job. I could see it being handy with expansion projects, where the architects are modeling an existing structure from scratch, so that they can then model the new addition, in order to show renderings of what the final project would look like.
Sorry for my extreme delay, this one slipped past me. Metashape allows for a lot of export options for models. I know that there are several videos and tutorials here on TH-cam about Metashape and Revit. I'd suggest checking some of those videos out. Also check out what file formats Revit can work with, and compare that to the export options Metashape has.
@@AZ-Drone I found one workflow that requires you to go through AutoDesk Recap first, and then create a .rcp or .rcs for Revit. I tried a OBJ file directly into Revit and it looked kind of wonky, lol.
@@JoeBoone82 Years ago I started looking into AutoDesk Recap myself. I was trying to find the best way to render models. I didn't spend enough time on the demo when I tested it.
@@AZ-Drone I guess if your client had wanted the 3d models for viewing, which file type and/or viewer would you have used to share the file with them? I imagine they would need software, or a web based brower, to open the .obj or whichever file you extracted from metashape?
A fun one to play around with is Luma Labs AI. I would like to try a SkyBrowse model at some point in the near future as well.
What video resolution did you use for input?
The video was shot at 1920 x 1080 at 60fps. The cruising speed was set to 8mph.
Hello, I followed your video instructions but the software says it cannot extract video data, what should I do?
Not sure on that one. Have you searched google for that specific message?
Hello, I followed your video instructions but the software says ''A media resource couldn't be resolved'', what should I do?
That sounds like you might have moved the video file from its initial location. I think I did that once and got the message you received.
Hi Rich! Thank you for the video. I'm just trying out metashape so I'm using the trial version for now. I do not have the dense cloud option in the dropdown menu (workflow) - Only option available is point cloud. Is it because of the version I am using?
Thank you!
It could be the version is the issue. I know the latest version has come out recently, and I haven't updated yet but plan to soon. Just need to find a little time between projects to test out the latest. Normally I align photos first, then generate the dense point cloud second. Under the workflow, what items are there?
@@AZ-Drone I just downloaded it recently so I don't know about older versions. under workflow I got: Align Photos - Build Mesh - Build Texture - Build point Cloud and Build Panorama.
there is no way to import an mp4 file correctly in my case, as it says "a media resource couldn't be resolved"
Do you know the reason why and how to solve that?
Thanks
Did you have any luck? I'm getting the same error.
@@MrDennisrsjr did not investigate, so surely it will behave the same way
You have to download the basic K codecs for your computer.
@@HoboChedda I guess that'll be done from the meta shape website?.. I'll search for downloads. Ta!
It doesn't working when i imput drone video "A media resource couldn't be resolved" . I make video from Dji-Mavic 4, 4k 60 fps and Metashape Pro
Just checking the steps you took. Open Metashape, go to File, go to Import, select Import Video, and select your video file. The file formats can be avi, flv, mov, or mp4.
I installed the k-lite codec and it worked.
How to Export orthofo images larger than 4 GB?
At present I haven't produced an orthomosaic that comes in over 4GB. Out of curiosity, how many images went into to making an ortho over 4GB?
@@AZ-Drone all proceshigh quality, average 1250 images
can u attach the drone video link
Unfortunately I think I deleted that video. Just did a search on my system and didn't find it.
By the way I don’t mean to sound presumptuous but I actually own a copy of Archie soft pro and if you ever want to collaborate with any projects then please let me know my name is Chris Chase I’m a UK citizen but based in Cyprus I would be happy to process any data DSM DTM et cetera like yourself I also use QGS and the software with RTK drones et cetera anyway Rich all the best
For some reason TH-cam put your comment in "held for review". Sorry about that, just fixed it.
Are there any similar programs that can do this that are not made by companies based in Russia?
Wow, didn't even realize that Metashape is from Russia. It's been so many years since I purchased it. There are other applications that will allow you to extract frames from your videos for the purpose of modeling. One that I just read up on to answer your questio is photomodeler.com. This program will let you extract images for use in modeling. If I were to use it I'd extract my stills with it, then pop it into WebODM (installed on my Mac already) and see how it works.
hi there!! can you please send me the 3d model for mail?? i really like to see ir closer!!
Unfortunately I can't. I've deleted that project, and apparently didn't share it on Sketchfab.
