    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

    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

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.

      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.

    • @notsure7874
      @notsure7874 20 ชั่วโมงที่ผ่านมา

      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 ...

      @DylanGorman  2 หลายเดือนก่อน +1

      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.

    • @1carlos83
      @1carlos83 2 หลายเดือนก่อน +2

      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.

    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. ;-)
