Thank you very much for the detailed explanation of the three systems, I am teaching myself to use Agisfoft Metashape for developing 3d models of cave interiors. Your video has really helped, I have just rendered your zip file of Church rock with excellent results the output quality is confirming my techniques and results for image capture underground. Excellent video.

In the future, the 2 others might become an option too, but my favorite aspect of photogrametry is that being a "standard" 3D model, it can be edited in something like Blender, fixed, simplified, reworked, given PBR textures, and then used as an optimized asset in a game engine, like Unity, and for exemple, uploaded to VRChat. So after having done all the drone videos, you could just, be there as a friend, with a properly scaled world, then have your friend walk towards it, showcasing just how big it actually is.

I'm curious if you have used your Insta 360 1 for the photogrammetry? I know that Meshroom supports 360 images. There may be instances where you are unable to use the drone for aerial shots, but could mount your 360 camera on a long selfi-stick to get over the subject.

I'm not into software war camps, but why using zbrush for cleaning up if you can use blender for free? Is there a huge benefit sticking to zbrush?

I have used blender, I'm just more familiar with and more proficient with ZBrush. I also hate blender's interface :) It's one of the worst softwares I've ever used. However, it IS free. I last used it 3-4 years ago, maybe it has gotten better.

Insta360 One R - I've had it for about 4 years and have mixed feelings about it - sometimes it's great, other times it will freeze and shut down for no reason - and to my eye the footage is decent. For the price it's a good little 360 camera.

Cool.....but where's the moon?
@MatthewBrennan 3 ай бұрын
During totality the moon moves in front of the sun (it's the black "hole" with sunlight shining around it) - when it's not occluding the sun, it's not visible (because the light is coming from behind it)... Unfortunately, the exposure settings on the 360 camera don't make it possible to really see the moon occluding the sun because there is enough light to still overexpose that area - but the shift from full/partial sunlight to eclipse is still pretty dramatic.

No - the photogrammetry is a DJI mavic 2 and a Sony A7Rii. Although, as I was watching the 360 footage, I think I will try to digitize one of the grave markers using the spherical video (the one that I walk around completely).

@MatthewBrennan 4 ай бұрын
360 imagery won't give you results like properly captured "photogrammetry"-style data - the typical 360 sensors are small, and you're cramming a lot of data into not-many-megapixels. If you absolutely have to use 360 data, good even scene lighting and a good 360 sensor are key, more than the processing technique.

You'd want to use LiDAR or structured light, or a combination of LiDAR and photogrammetry. I have digitized wrecked cars before using photogrammetry - and LiDAR is often used to document crash scenes.

I used a Mavic 2 for this model. I have used a number of different drones for photogrammetry in the past, but haven't tried the Mavic 3 yet, although I don't think the Cine model adds anything particularly useful for traditional photogrammetry.

no, probably not, because the Gaussian splatting is based on image data, not LiDAR data. You could use a photogrammetry program to align your LiDAR datasets to imagery, though.
