Notes about capture 3d

Will be great to acquire some nice gadgets avaiable over there, but budget acts!

So some photogrammetry concepts are good to learn, and internet is our friend.

For most of us solutions as David are very welcome. And don't forget freenect! and besides them there are other solutions that can fit your requirements without spending lot of money. A perfect example is Skanect.

By my side, OpenCV is the future because hardware seems not to be a problem. Not easy anyway...

And keeping an eye at Leap...

Improving data

Finally, the first capture with interesting points marked on its back. Not only this, also scanned before and after five miuntes of exercice... As expected, shapes are different. Love it.

Next step, to cad.

Horses, more than a hobby.

So yes, that is. Since a child. With the time I worked with them, as a guide or as a stableman. And now mainly using a computer between us. My actual goal is to provide a perfect fited tree to manufacture hand-made saddles at JVentura.

To do that a long way was done. Lot of processes are involved, many of them with dedicated hardware. Even today I'm in new improvements, always trying to do the best.

Do a custom fitted saddle means that we need to mesure all, says your back-shape horse and your desired position. Then a mold is calculated and cnc machined to obtain one particular saddle tree. We use carbon-fiber laminated shapes as a tree, so later leathers, inserts and foams are added.

And this is my job: from taking measures to machine the mold.

First of all I check for contractures, as is not a good idea to design a saddle for a contractured back-horse. When it becomes relaxed (many professionals do it) we can proceed. So then I digitally scan it's back shape, in this way I can calculate a perfect fitted surface tree. Finally a mold is prepared and machined.

Our partner laminates the carbon fiber over the mold: this very important stage is done by high skilled professionals. The result is saw-cutted, obtaining the tree or carbon-laminate frame, where the saddle is arround hand-made constructed.

You can see it in JVentura site.

This blog tries to be a collection of experiences and results from my job.

Live scans

well, can't finish without showing the actual situation.

decimated, detextured, deanyelse, but that is:

Updated: using sketchfab to show 3d models. Nice site btw.

Capture 3d data

And just to finish for today, let's show one way I used to use to scan moving shapes.

Using the great piece of soft photomodeler.com. Seems that actually they are implementing more cv libraries, but still not used them.

To scan them, 3 calibrated cams are used, with some proper software. The pros: very high end results (low residuals, hig res,...) The con: as low vertex as markers are procesed. Manually, of course ;)

One CAD shot

Maybe a screenshot shows better what I do. In this case a backhorse mesh is used to design a carbon-fiber laminated frame.

Regarding mesh, just say that it was captured with a dedicated scanning solution. The goal is to produce a perfect fitted saddle for high preformance purpose.

First thought

Hi all,

probably I must started this blog long time ago...

let's see now how long it will runs!
