Hello everyone,
I attach to this post my entry for #RCdragons competition.
The entry I submit is a 3D model of a dragon that can be found in Ljubljana on the Dragon Bridge.
At the moment I took the photos of the dragon I was at the very beginning moment went I discovered photogrammetry. I didn't know exactly how to do it properly so I did a lot of mistakes. I took 492 photos in a big hurry, 24 minutes, but I have only selected 424 out of them for the model but still a couple of them are not clear enough due to f-stop and exposure time. The weather changed a lot in this short amount of time from cloudy to sunny and then quite dark for sunset.
I estimate the height of the dragon to be around 5-6 meters which made is quite difficult to shoot photos of it. I handheld the camera on the tripod to take upper part photos so multiple photos I took were blurry. The model has a couple of problems regarding the wings which can be seen in the attached photos. I did clear a bit the bad parts with the lasso tool which can be seen in the attached photos.
A video made in RealityCapture can be found on Youtube:
Location and time: Ljubljana, Dragon Bridge, 2016/10/12 7:05pm
Technical data:
Nikon D7000 camera and Sigma 17-70 f2.8-4 Contemporary lens
424 photos selected with various zoom levels, f-stops and ISO values
Shooting time: 24 minutes (was on a big rush but I really wanted to take photos of it)
The model was processed on high detail and then I simplified it and then cut off with the lasso tool mainly the upper parts from the wings.
Hope to get back there one day and shoot it properly.
Best regards everyone,
Cristian from Romania

Here in Finland there's hardly any outdoor dragon statues. That's why I asked help from my Vietnamese friend. He brought me a small 20 cm tall wooden dragon statue. He said the statue was bought years ago in some random Vietnamese tourist gift shop.
The wood was very reflective so I decided to use 3d scan spray. This is first time I used 3d scan spray (some of my fingerprints visible :D). In fact this is my first proper small scale scan. At my work I'm scanning buildings with drone for BIM modeling.
I also bought a cheap light tent and led panels to get the best possible result.
- Camera: Canon EOS 5D Mark IV
- Lens: Canon 24-70mm EF f2.8L II USM
- 250 photos
- Reconstructed on high detail
- Raw model 28 milj poly -> simplified to 1,2 milj poly

And some CGI fun!

Dragon at Drakenfontein, 's Hertogenbosch
Another scan from my trip to Netherlands, located in 's Hertogenbosch also know as Den Bosch
small city close to Utrecht, this dragon is a part of their famous Drakenfontein, which of course means Dragon fountain. It is the famous monument of the city, erected in 1903 as a drinking fountain, but never served this function. The statue was built in memory of the twin daughters of a local esquire who both died tragically in 1881 at the age of only 17.
This shooting was the most hilarious one. When I did the research online, the pictures I found had the fountain empty, without water. Sure enough, when I arrived to Den Bosch with a tight schedule to do the shooting and return back, the fountain was full of water. I started the shooting while thinking how to get inside the fountain. First I thought i will just get in bare feet, but it was still very cold. In the end , I've asked for ladder in the local cafe, fortunatelly they've borrowed me one and I used it to move close to the dragon by doing little hops on the ladder. That day, it was the day of annual carnival and people were already in an upbeat mood, up for some pranks. One guy tried to grab and steal my ladder so I could not leave the fountain, fortunately, I've defended the ladder and his shoes got wet :D.

Zmajski most – the Dragon Bridge, Ljubljana
Hi Cristian!
Seems we scanned the same dragon! :) I hope my submission is not duplicate since we compete in a different category and my post is still eligible.
Zmajski most, the Dragon bridge is a remarkable Art Noveau architecture piece inaugurated in 1901. The four dragon sculptures decorating it, were designed by Giorgio Zaninovich.
As I had so many dragones to process, to reconstruct the set captured in Ljubljana I decided to try Google Cloud Platform Compute Engine. After some trials and errors, I managed to start the virtual machine, log in with the remote desktop and install the RC. I acquired additional Steam licence to be able to process two datasets in parallel.
Technical data about scanning process:
Sony A5100 24MPx ASP-C CMOS + 16-50mm PZ OSS
Extendable rod
Ladder
Samsung S8 as a remote control
ARW exported to PNG
Shooting for 3 hours

Hi Dragon Hunters ;)
Dragons are around us. They are in legends, museum, art galleries...some of them are on the streets. But not only as sculptures. On the streets of Szczecin (Poland) we can meet dragons on the historical street pumps. They were built in the XIXth century. Until today people can use them to provide water (not suitable for drinking!). Why these dragons? Because they are historical, beautiful and...quite difficult to model with close range photogrammetry - they are glossy. Of course in RC everything is possible :)
You can find simplified model on my Sketchfab account*:
https://skfb.ly/6IFOO
*I had a lot of problem with upload directly from RC. Only Sketchfab API token helped.More detailed model on my server:
http://www.archservice.pl/models/pompazeromskiego.htmlOf course, everything was done only in RealityCapture (photo align, reconstruction, clean, manual selection retopo, texture).
328 photos with Sony Alpha 6000+16-50mm Sony Lens with tripod, about 2 hours taking photos, about 2 hours processing.
PS
Dozens of pumps (some of them with dragons) are still waiting for their photo sessions ;)

Lego – Dragon Dance 80102, Chinese New Year
As there are not many dragons in Europe left and I managed to capture only five of them, I tried to think outside the box and come up with the solution for the challenge. I decided to get a box of LEGO.
Conveniently enough, the LEGO website lists all the sets with dragons.
https://www.lego.com/en-us/products/categories/animals/fantasy-animals/dragonsWith by girlfriend, we both agreed that the set we like most is the limited edition for the Chinese New year, titled Dragon Dance with the code number 80102.
When I played with the LEGO set, it always felt for me like I am inside of my creations. Now with the photogrammetry and VR, I can transcend the scales and teleport myself next to that plastic dragon and be as small as the LEGO figure.
I have a touching memories of LEGO, it shaped my technical skills so much. I wish I could say thanks again tomy mother and my grand father for all the effort and risks they take to get my my favourite toy. As a kid I never understood, why we had to hide the sets while crossing the borders back to the communist Czechoslovakia. But now I understand, how risky it was for my grandfather, who was a former political prisoner.
Location:
home
Technical data about scanning process:
Sony A5100 24MPx ASP-C CMOS + 16-50mm PZ OSS
CPL filter 40.5mm
Tripod
50 images for texture + 100 images after applying baby powder
Markers and color chart pad
Shooting time about 8 hours, lot of failed sets as the parts are not rigid enough and very glossy even with CPL.
Processing time about 1 hour.

Hi everyone! Here's my last minute entry to the competition.
You can find this statue in Dundee, Scotland, guarding the east of high street. It is the work of Alistair Smart and Tony Morror, and was erected in the 1990s.
This statue is based on the local Dundee legend of the Nine Maidens or The Strathmartine Dragon. Dragons are also present on Dundee's coat of arms.
According the legend, an old farmer had sent one of his nine daughters to take water from the well. As she didn't return, he sent his other daughters, one by one, but none of them came back. When he went to look for them, he found them dead, at the feet of a dragon. The old farmer couldn't fight the beast, and went to the town to look for help. Martin, the lover of one of the maidens, would be the one to slay the dragon while the townfolk shouted "Strike, Martin". According to the legend this was the origin of the name of Strathmartine , a village near Dundee.
This legend is also thought to be related to Balluderon stone (also known as Martin's Stone), a Pictish symbol stone which depicts a dragon-like creature.
I have used a Nikon D610 camera with a Nikkor 35mm. ISO-200, f/3.5, 1/160.
261 photos walking around. No tripod.

*I have uploaded the model directly to Sketchfab. I hope it's okay. I have been trying to upload it through Reality Capture, but haven't been able to due to some sort of error (script error).

That was really quite a nice experience to try your product. It is awsome with great results. I am on the way to work on improving my skills with this program.
Entry created for Dragons Around the World´s Competition/ "RC for newbies" category.
Location:
The dragon is a symbol of the Klagenfurt city and can be found in the new square, right in the middle. Legend has it that a water dragon who ravaged the neighborhood and killed the local people was killed by the Duke of Carinthia and in his honor the city of Klagenfurt was founded (it can also be translated as "lamentation from the ford";
Thank you.
Viktor
