Our drone mapping course is free of charge to all who are interested. It does cost us to have it online so if you can donate to help offset the cost, Please do.

In this video, I show how to make your 3D model look good even if your data doesn't. This lesson is long but has many little-known secrets to fixing problem areas that can occur when using photogrammetry. - วิทยาศาสตร์และเทคโนโลยี
Finally, a professional video tutorial for Agisoft! I have a suggestion for improvement: at the timestamp 24:22, instead of opting to select everything and then deselect using a different view, consider using the 'visible selection' option. This way, you will exclusively choose the element you are currently viewing, eliminating the selection of elements positioned behind it
Thank you for that suggestion. I didn’t even know about that option. I will definitely give it a try.
Thank you for the nice explanation. I first learned how to use Agisoft from you 4 years ago. I also thank you for this. I'm your subscriber, you haven't posted for a long time, this post was very useful. We are a company that makes mine maps and calculates their volumes in Turkey. We use agisoft in these studies. We use the agisoft workflow prepared by the USGS and prepare our maps accordingly. If you want to use it, I can share it with you. Thanks again for your sharing.
@dakin7563 first let me say, I am honored that you have found my videos helpful. Thank you for telling me. It is true I have been away for a while. I hope to make more helpful content soon. I would love it if you shared the information with me from the USGS. you can send it to guardmy6@gmail.com
That was excellent, thanks. I just hope that it works on the standard edition, as there is no way I can afford the pro!
I wish I could tell you it will but I do not know which features work in the standard. If you are a student in school then you can get the pro version much cheaper!
Great tutorial, I'm only familiar with Pix4D but watching this it looks as though Metashape has far more functionality to edit and refine a project. From your experience, do you find Metashape better than Pix4D?
@user-fh7ku2yc5v In many ways I consider Agisoft better than any other photogrammetry software. It does allow for more control of your project. I compare Agisoft to a German Shephard- It is not the best at any one thing but it is really good at everything. I am still looking for a way to make a better-looking Ortho but I can't complain
about the quality it currently makes.
@@GM6DroneMapping Thankyou for your insight!
photogrammetry still relies on classical algorithms. we need much more sophisticated machine learning techniques. The potential is very significant.
Something like google earth/streetview is an obvious opportunity for breakthrough because they have the means. Good photogrammetry could make models that look better than if the best humans made them instead of the clay blobs we get now.
@DanFrederiksen I whole heartdly agree with you and have a lot more I could say on that topic. For now I will just add, utilizing Unreal Engine does wonders for the models. I recently worked with a gaming company and saw what is possible. I am only a baby with Unreal Engine but the potential is huge.
Completely agree, and proof of this is the time it takes for data processing in almost any project instance. We need algorithms more related to AI than massive (slow and often deficient) processing. There is a lack of software that recognizes objects and, based on that, optimizes calculations.
good example: NVIDIA Instant NeRF

Everyone is using the professional version of metashape on all these tutorial videos, is everyone really paying the $3.5k to use the software or is there something I'm missing?
Yes I believe most people are paying $3500. It is cheaper than Pix4D. You can also get the same version as a student for $500. You just need a school email address
@@GM6DroneMapping aren't there significant differences for the student version? (I'm not familiar with that one) and thanks for getting back to me so quickly!
No, exactly the same.
