After a long break, here’s something special! Thanks to the joint effort with @Weird_Old_World, we now have a 3D model of the mysterious Zone X (Cusco) with tunnels, built from 7,400 images from Insta360 X3 camera and drone footage. Enjoy! https://t.co/NFP0xMQzUd

Huge thanks to @Weird_Old_World for the amazing drone footage of Ollantaytambo, which allowed me to create a photogrammetric model of this fascinating site! A total of 1,357 images were extracted from 4K videos, and the final mesh contains 17 mill. faces. https://t.co/mBedqZZuDA

Thanks to another amazing collaboration with @Weird_Old_World, a photogrammetric 3D model of the nearly 200-meter-long Calle Inca Roca street in Cusco was created. The reconstruction required only 1,179 frames extracted from a 4K iPhone video! Enjoy the animation with nice music!
Another photogrammetric 3D model created by the relentless Marián Marčiš. Go check his other work on his page @mariusderomanu3. This one is of Calle Inca Roca / Hatun Rumiyoc, a famous street in Cusco’s historic center. Try to spot the iconic 12-angled stone. I’ll link the 3D

Another exciting collaboration with @WeirdOldWorld 🙂. Some geoglyphs in Nazca are so large that they only fit into a drone's frame from a greater height, but then the lines become less distinct. An excellent opportunity for photogrammetry 😉. Enjoy the short animation!
In a remote corner of the Palpa desert lie some rarely (if ever) observed geoglyphs, made up of lines in the sand so fine and rocks so small that they can’t be seen on satellite images (at least not the ones available to the public) and you can’t really see them from the ground

Who would like to see a real movie based on this epic trailer? I had the pleasure of collaborating with @Weird_Old_World once again to create something special—packed with Easter eggs—that only this community will truly appreciate. Enjoy and have fun! 😀

Hold onto your hats! Thanks to a joint effort with @Weird_Old_World, we've photogrammetrically mapped 2.2 km² of Sacsayhuaman, all the way to the Temple of the Moon and the Snake Cave. Stay tuned until the end of the video!

This one was tougher, but we did it. Thanks to the amazing drone videos from @Weird_Old_World, we were able to photogrammetrically reconstruct almost the entire Sacsayhuamán site using Agisoft Metashape software — 1,103 images, 200 million points.

Just experimenting with @RealityCapture_. Big thanks to HistoryforGRANITE for providing drone video footage of the Khafre pyramid. 1,911 images were aligned in 2 h 37 m, and a mesh with 16.7 million points was generated in 2 h 8 m. Animation created in @CloudCompareGPL.

Each of the methods produced slightly different results, but one thing is clear: Every one of you, with all your videos and scans, is mapping the ancient sites and objects within them and collecting data usable for real scientific purposes. Keep up the good work! (3/3)

The width of the face is approximately 0.75 m. If we neglect the damaged parts, we can see significant deviations in symmetry, especially in the area of the eyes (± 10 mm). Even on the cheeks, there are deviations of up to 5 mm. I leave the conclusions up to you. (2/3)

This is the power of social networks: Thanks to the video from @FunnyOldeWorld, LiDAR scan from @outofspace2, and Luma AI mesh from @ArtifactFNDN, we now have three independent datasets confirming the same result about the degree of symmetry of the granite head in Ramesseum.(1/3)

Is there anyone who has more photos or videos of this head in Ramesseum (Luxor)? Big thanks to @FunnyOldeWorld for one of her older YouTube videos, from which it was possible to partially reconstruct the 3D model. However, for a reliable analysis of symmetry, we need more data.

Nevertheless, it is still an admirable achievement. Deviations in the polished crown are greatest in the restored parts on the peripheral edge, but ancient craftsmen preserved symmetry with an error of up to 5 mm in the upper curved parts. (3/3)

Photogrammetric analysis shows significant asymmetry in both crowns, with deviations in some places exceeding 1 cm, which for an object with a height of up to 2 m represents a relative error of 1:200 or worse. Units for values in the images are in meters. (2/3)

Everyone who has been to the Luxor Temple surely knows these remnants of granite statues. Especially the crown on the right image is perfectly polished, and one would say that their surfaces are perfectly worked and symmetrical. Well, they are not...(1/3)
