Wow, this is excellent. I fly nearly every job as almost a backup insurance plan. If I miss a manhole, I can grab it from my point cloud. But pretty impressed with the accuracy.

We often do as well. It really doesn't add much time at all especially in you're flying with an RTK enabled drone.

30:09 my goodness thats a long processing time. Great video thou. Learned a lot thanks.

Especially for a relatively small site. My GPU and CPU are a bit dated. Once I replace them in a few weeks I'll run the dataset again and tweak some settings and create a video comparison on processing times. I imagine it wont be hard to cut that down by 400-500%

@@ryutsuisen This was on my older computer, i7, 64gb ram, 1070 GTX but I was running an older version of Agisoft. When I updated it, it really cut down on processing times. With my newer laptop and newer ver of metashape Id be looking at a couple hours to process this out. This one I flew with a P4P.

@@The3rdDimensionSurveying thank you! Great video btw. I'm new to photogrammetry and been practicing with my Air 2S and Metashape trial version. Been enjoying that software a lot compared to using RealityCapture. First personal project I worked on to practice with Data Acquisition and processing with different settings in Metashape. kzread.info/dash/bejne/c3yFtJt6j5q-Yco.html

good informative video. Something I do for my Orthomosaics is instead of a Geo .tiff or ECW I use a free program called IrfanView64 and use that to convert to a .jpg. It dramatically reduces file size and quality is still good while maintaining the EXIF data for for programs such as Civil 3D or Carlson Software. Once again thanks for the info.

Very interesting. Agisoft exports jpeg and they are a much smaller file size but I've never used them in C3D before. I am definitely going to try this and add a comparison into my next video. Thanks for the tip!

Great video! Thank you for taking the time to create this. What are your recommendations for converting .tif files to .ecw? I have licenses for ArcMap, LP360, and Civil 3D and I was hoping one of these could convert it but I haven't found a way yet. I am seeing that many people are using Global mapper to do it. Thanks!

I've always used global mapper myself. I know ECWs are a proprietary format so I'm not too sure if there are any open source pieces of software that are capable of the conversion. If you find an answer to this question please let me know!

@@The3rdDimensionSurveying Great! Thank you and I will let you know if I find anything.

Think you will find Reality capture does a better job for this kind of work. Also running flight plans that consistently vary in elevation will produce better results with less shots. This is due to the way photogrammetry triangulates the data. Its part of why you see better results with the very oblique path as well. the more variation, less uniform, the better your results from my experience.

Im using CloudCompare in the majority of the video

What is the price of this processing??

You’d have to look up Agisoft Metashape. I have no affiliation with them.

"the processingcomputer i'm using is no slow*** it was designed to process photogrammetry ... its 5 years old" that made me laugh so hard 🤣🤣🤣 even after 2 years your pc is slow af, compared to an average new one.
