Drones - The RIGHT way to Calculate Volumes with Agisoft Metashape

Calculating volumes in Metashape (and other photogram software) is simple, maybe too simple.

In this video we take a look at the correct method, as well as some tips and tricks to help you calculate more accurate volumes!

i absolutely love your videos you have taught me so much

Hi, I don't know if you believe me but I watched all your videos related to Agisoft and learned a lot so for these series of videos I am very grateful. I was trying to follow you step by step until I needed to draw a new polyline over the old one to divide the first shape, but the old shape vertex markers and points were not visible to snap on. I tried a lot to find out why but with no result. I am using the latest version of Agisoft.

great. more real life work tips would be welcomed. thnx

Thanks for the instructional videos. I want to ask a question. In a documentary about Egypt, they were measuring the length and height of the pyramids using Realty Capture. How to make basic measurements such as door, window lengths or building height on the building where we created the 3d mesh model with Agisoft and pix4d? It would be very helpful for survey areas if you prepared a video on this subject. thanks.

Very interesting and helpful Video.
What are the specifics of your hardware you are using for agisoft?
Can't wait to see more of your Videos :)

Can you make a video on ortho colour adjust for particular areas

[MrDennisrsjr]

Im having trouble understanding best fit and mean plane. I am trying to calculate the volume of a pile of mulch sitting on a slope. Would best fit be the correct option for this scenario?

Ganhou uma inscrita! Excelente explicação! Uma dúvida: não houve classificação de pontos, então esse MDE é o MDS?

I'm just starting to do stock piles so this is very helpful. Unfortunately I have several piles in bunkers and some up against vertical walls on one side. There are also some where the edged of the piles are obscured by trees. Some piles have conveyors that need to be removed.
I've been making Ortho's and DTM's but now I think I need to watch your other video to see how you got to where this video started. I think I've been doing it differently.

Do you offer courses that go into more detail than the YT videos?
Thanks!

[jerseyshoredroneservices]

I'm back again LOL
When you calculated the different results with the two different methods, how did you decide that the 2-part method gave the correct answer? Was it just that the profile(s) were more uniform? How confident are you that the result was correct and why?
I'm asking the tough questions because I want to know how to answer them for myself and potential clients. I don't feel right about selling a service when I lack confidence in the results and/or wouldn't be able to answer that question for a client.

I've been practicing a lot and even did some of my Metashape projects on the Measure Ground Control platform to compare the results. MGC uses Pix4D cloud for processing.
The results are similar between MGC and Metashape but both seem very large. For example one pile came out to 600 yd3. I started thinking about how many loads of material that is. With big 10yd trucks there would be 60 truck loads of material. It just seems like too much. Is it normal for the actual volume to be different that what it appears to be visually?

Thanks again!!

Hello
How did you clip the densecloud at the size ouf your boundery box and generate a DEM only the size of the box ( not all the photo set )

[jerseyshoredroneservices]

While watching this video again after watching the other ones I see that you didn't classify ground points and built the DEM from the dense cloud using all classes 2:01
When measuring stockpiles is it typical to do it this way or are there times when we should classify ground points and build the DEM as a DTM, using the ground class. Is that how we remove conveyors and other machinery from the piles? THANKS!
Edit: When I did classify ground points I noticed that the top of one pile disappeared. I did it three times with different settings but always lost the top of the pile. I saw this when I filtered by ground class. I don't think this is good since I need to calculate the volume of the pile.
I'm confused now...

How can I calculate the volume excavated? .. that does not protrude from the ground

If I run my flight and data capture using dronelink can I then upload the data into Metashape?
