Beyond the content itself, it's clear you put thought and consideration into the production value as well. Extremely good video, can't wait to see more
I feel like you didn't do too much justice for the M3E especially with its smart oblique feature. I'm certain the pointcloud with smart oblique turned on would register a lot more points especially in the built up area test case.
Any idiot could have seen that when Amazon shifted ALL their tech to video cameras and the software / recognition algorithms to use with them. Instead of planting rfid in their automated stores, they put cameras everywhere and progressed with making it so they could do just about EVERYTHING with just video :P
@ I see you fixing with that big boy to that rock robotics are three v2 i’m saving up for that. It is the ultimate photogrammetry and LiDar combined game changer.
Nice Dyl. Hey can you share the settings you use for the L2, and the path? I seem to miss a lot of data, area, detail, even using the L2. The automatic path generated by the DJI Pilot seems to have quite a bit of spacing between the runs and cuts the area a bit short, generating some circular scans as it turns at the ends of each run , and manually editing the path is something I haven't been able to do with the M350/L2 setup
Great tutorial Dylan !! Quick question. Are you releasing any LiDAR-related courses soon ? Seems like there's not enough training material out there for people wanting to get into the LiDAR field. I'm talking about thorough courses like detailed workflows, acquisition (settings, flying patterns etc...), processing, exporting and so on. Thanks man, keep up the great work !!! Merry Christmas !
Wow ! Impressive differences ! So, photogrammetry is a better use if there's no vegetation ^^ And it's too bad that those technology cannot combine each other into a single camera. Maybe in few years... BTW thank you for the video ! I really enjoyed 👍👍
@@DylanGorman I came here looking for more info on exactly this part. I would love to see a video on combining them, either from a single drone that has both technologies, that captures it all simultaneously, or methods used to combine them after the fact, potentially from different drones flying different flights - maybe using ground control points, or some other method of overlaying the data.
This video is wonderful. Your explanations are on point. It's a fun ride if you need this 'STUFF'. My approached comes from a photography point of view. I just want to capture art. Examples might be a barrier island at sunrise, a horse farm in the snow, how about a neighbor's beach front property with ocean and their surrounding property. Pieces of Art that customers can commission. This is what I want to do. My question is...do I really have to step up to the Enterprise Drones or can I still use my DJI Air2S? Yes, the Air2S couple with a third party software like DroneLink or something else. I just want ART. Thanks for listening.
I have the DJI Mavic Air 2s I would like to see more videos on that particular drone all what I could use it for photogrammetry and ladder, which I’m pretty sure lied or out of the question
Incorrect. No need for Lidar in zero canopy area. Riegl Lidar systems start at $50,000 and unless you're using that you're not serious anyway. Besides, after exhaustive testing, I can get as good data from a $5000 setup as a $80,000 one. But most people won't test for years. They haven't got the time, money, patience or desire.
Can you elaborate on when you said the maps won't be "survey grade" since you aren't using GCPs? In talking with people in the industry about adding an RTK module to my drone, I've been told the RTK would reduce or completely eliminate the need for GCPs. If you had RTK during these maps, how accurate were they compared to a non-RTK flight? Thank you.
Hi, so I want to use drone mapping and monitoring to help me with crop health on my farm. Which can identify problematic areas in terms of fungus and insect pressure the best? Lidar or multispectrul
You most likely will be best served with a multispectral drone. They're a little over 4500 bucks without a remote from B&H I think. The ones I've seen have the RTK module, and I'm not really sure you need that. I think you need additional gear to really take advantage of that feature - ground gear, like telemetry equipment like surveyors use. But - it's a 700 dollar add-on so if you might need it, maybe can use it, and you don't really save anything by omitting it ...
Have a project that requires to scan a large 3 story building for the purposes of recreating Arch Plans “ as built”. No vegetation. Would photogrametry be enough? Thx
Yes it would work out really well! I have a dedicated workflow on my online course if you are interested that guides you on how to capture high-quality 3D models. Otherwise, capture lots of photos from as many angles as possible and you should get a good model.
In relation to building façade inspections, I assume that photogrammetry would be more effective for referencing specific areas of the façade? The example you provided, showcasing the exposed rebar on the silo, is an excellent illustration. However, I also need the capability to scan areas beneath tree canopies. I'm curious whether LiDAR can deliver image quality comparable to the one you demonstrated for the exposed rebar. Thanks for all the info in the video - I just subscribed to your channel.
Yes, but Ive just got L2, do you think I should get M3E for specific tasks or just try do it with l2 or instead of buying M3E get P1? Hmmm - considering for models / facades/ im surveyor proffesional licensed so you have a clue what Im doing mostly @@Louisianahelicam
@@DylanGorman Yes, but as you can do it in mm accuracy instead of cm accuracy you would attract a whole different class of customers, and you could survey much larger areas from a higher altitude.
@@DylanGorman Very true, but usually those who are willing to pay for mm accuracy have deeper pockets, but require more convincing to get as a client. Don't get me wrong, the L2 is extremly good as a filler for the gap in the market.
Seems to me it's not an either or situation, use sensor fusion! We were doing it on a small scale back in the 90s surveying days. Worked for a startup making laser survey hardware and software. Make a laser range map, take a bunch of pictures, map the pix onto the 3d range data. Took a whole day sometimes of computing time. Compute is so much cheaper today, and algorithms are better. Surprised you're not doing this, yet. ;-)
Good evening! I'm really interested in your videos and would love to help take your channel even further. My name is Val, and I'm a video editor who specializes in creating shorts and TikToks. I’d be happy to offer 3 free shorts as a sample of my work. If you like what I create, we can discuss potential collaboration moving forward. Looking forward to hearing from you!
I think you guys in the US are not aware of how lucky you are with your drone laws, flying a M350 RTK above public spaces without any other preparation or fencing is impossible in Europe, NOT EVEN WITH A M3E.
Neither the answer for now is Gaussians. I would say get the data, use postshot to train it and go Gaussian splats. The difference is remarkable and life like environments.
How did you get your start? Are you an engineer? Can anyone get work or is it a niche engineering thing? Nobody in Canada will let or use your inspection data unless you got the papers to prove you know what your talking about.
Thanks!

Awesome work Dylan, best explaination/comparison by far.
great video, very well composed, relevant, no bs. subbed!

Great video brother, I need to get out there for some training soon. Great info and tutorial 👍
We’ve got more workshops coming up next year!
The title is good. When my friend bought a Faro scanner for $45k the rep said wait until photogrametry comes out. lol.
Oh boy lol, not what you want to hear after spending $45k

I usually do a 35%-45% side overlap with 70% frontal. 8-15mph speed for capture and between 180ft-260ft agl
Thanks Dylan. Looks like I should pick up your course.

You can 100% combine both technologies together!
The L2 has both LIDAR and an RGB camera. Thats how the point cloud is colourised.

Photogrammetry for everyday use. Lidar for professional use 👍

How much can you charge for Lidar versus the photogrammetry?

Without GCPs, how would you know if RTK is accurate?
One or two checkpoints?
Why use a point cloud, when you have access to a good GCP created 3D model, with no tree canopy's?

@@wzfellguard1 Not sure. I only use what I build for mapping
I am mapping/scaling/sizing whales over the ocean so which method is better?
To be fair, the Teledyne LiDAR is 10 times more accurate (5 mm vs 5 cm), does 500 Khz puls rate and can do much higher altitude mapping.
That system is also $150K+....
@@DylanGorman Yes, but as you can do it in mm accuracy instead of cm accuracy you would attract a whole different class of customers, and you could survey much larger areas from a higher altitude.
@@TheEsseboy I think it also depends on the customer. 85% of my clients don't need mm accuracy, 3-5cm is more than enough.
@@DylanGorman Very true, but usually those who are willing to pay for mm accuracy have deeper pockets, but require more convincing to get as a client. Don't get me wrong, the L2 is extremly good as a filler for the gap in the market.
Do you see DJI coming out with a sub $2,000 Lidar drone for hobbyists?
AwsAWsome

@@DylanGorman no offense man, love your videos and congrats on your business!
No real answer, really depends on what your use case is and where/what you're mapping.
Hey cool, can anyone help me get started in this field. I'd owe you.......big time.....
I’ve got free and paid courses on my training platform if your looking for dedicated training

Not yet! As much as I love gaussian splats, they still have a long way to go before they are used for commercial grade work.
You can’t use the photogrammetry for anything and the lidar .. but I’m speaking from a visual look. I think the lidar is the way to go for data.
@@DylanGormannot to mention how for so many things you need a closed mesh. Not exactly something Gaussians are known for.
