Drone LiDAR vs Photogrammetry | Epic Stadium 3D model

We need to create a 3D model of this football stadium! See how a LiDAR Drone and DJI Inspire 2 Photogrammetry mission compare on capturing the FULL 3D model of the Stadium.

I was expecting you would be merging the two data sets- using the images to texture the LIDAR model.. would that be possible at all - and give a more accurate 3D model ?

You physically look like you're in pain from forcing such a big smile lol

Is there a way to blend the data from lidar with photogrammetry by matching your GCPs? Could it help to make the photorealistic 3d model more accurate?

I dig his depth of knowledge and enthusiasm! It’s refreshing.

First: You guys make great videos!!! At this video it looks like you compare the LiDAR point cloud with the 3D mesh model from photogrammetry (based on pc)... How does the photogrammetry point cloud looks like? This would be the right comparison in my opinion.

Even with the "not so great" Inspire Camera Setup (for photogrammetry) you should get a point cloud which delivers more information then the bad looking drone deploy mesh model.

Combining the laser scan with photogrammetry in software like Reality Capture or Metashape would get you a great model with great textures.

The LiDAR data are really amazing! But it is not fair to compare a LiDAR point Cloud with a photogrammetry 3D Mesh. These are 2 different things!

Hi can you compare the 2 datasets against each other, maybe run a section through and see how the look against each other?

[rushee]

Aye its Todd from breaking bad, great video btw

Have you tried to integrate both data into a single 3D model? There are software that can process both data, to get the best of both worlds (3D constrain and precision from Lidar, and photographic texture from photogrammetry), and in fact, it can increase overall spatial resolution.

Can lidar data be used by architecture for construction ??

[zteaxon]

It would be amazing to get some device that uses both lidar AND photogammetry and then uses AI to interpret the data and make a 3D model.
I think if the geometry would get interpreted by an advanced AI the model could get near perfect.

Did you also used SLAM for localization while doing point cloud registration or only feature matching ?

[label]

Hi, which software you are using to process your lidar data?

[anujkul]

Can u measure the depth of the stairs / stands using photogrammetry or u need LIDAR for that. Also MSL height ?? or do u take that from GPS ??

Oblique photos are critical for 3D rendering. I cannot stress enough just how important oblique photos in your Drone Deploy uploads. Especially for stockpile volume calculations.

[jybyrd]

Id like to see using LIDAR to measure surface elevation through overgrown property. Important for landslide mapping.

This would be good for flight sim 2020 add ons, epic video mate

Hi great video, I would like to mention that IMO you could be using a better photogrammetry setup, you are comparing a high-end quality lidar system (among the different lidar possiblities) vs a more or less mid-end quality photogrammetry system (among the different photogrammetry systems possibilities) from my point of view. Also you are comparing the point cloud of the lidar post process vs the mesh of the photogrammetry postprocess, I don't know if drone deploy can postprocess the pointcloud but in pix4d, sometimes I see point cloud more accurate and sharp than the mesh. I really like this sector and I've been testing lidar vs photogrammetry sometimes trying to improve the photogrammetry weak points trying to reach the "easy to get" lidar quality.

Are you doing the landfill in Columbia Missouri
