Taking Measurements from a Photo using Tracker (3D Universe)

As part of the e-NABLE volunteer community, I spend a great deal of time making free prosthetic devices for people who need them (mostly children who wouldn't be able to otherwise afford them).
Part of the process involves taking measurements of the recipient's hand in order to properly scale the files for 3D printing. Most often, these measurements are obtained from photos.
This video shows how to use the free Tracker software to obtain the necessary measurements from a photo in just minutes, and then how to enter those measurements into e-NABLE's new Handomatic web application to generate STL files in exactly the right size.
Thanks to Marc Petrykowski, who provided me with the info about this software. And thanks to all of the e-NABLE volunteers who have worked so hard on building the new Handomatic web application!

Fantastic video, thanks for making it. Just found your video and then the software after I watched the video.

@nicholashall3479 10 лет назад

Fantastic work. I was stumped on what to do with the intake photos that I received until I watched this. Thanks for taking the time to shoot and edit this!

@bhawnasoni5982 4 года назад

this video came out to be very useful for me. I am doing my research in hand and foot measurements for height estimation and i am trying to use this software to study the digital images also but m not able to find any research papers related to this. Can you please help me if you have any knowledge regarding this?

@viniksven 2 года назад

Search for Photogrammetry, Homography, Direct Linear Transform, etc.

@indhu1625 3 года назад

Is it only for parts of body.? Or I can measure height of any images like wall of the building?

@3duniverseOrgWelcomesYou 3 года назад

You can measure anything you like, as long as the image is taken from a good angle (for a building, you'd want as close to 90-degree angles as possible). Then you'd have to have some kind of distance reference. So for example, you could measure the width of a window and use that to calibrate the image. Then you could measure walls, roof, etc.

Apparently the software it´s no longer available online, can you share the software with a link if it's freeware? In advance thanks!

This is for 2-d measurement. How to get to the depth of the object?

My son suffered amputation, but he has his thumb, how do? help me? please

@3duniverseOrgWelcomesYou 10 лет назад

Hi, margareth margoth. The work I do producing 3D printed prosthetic devices is through a volunteer community called e-NABLE (enablingthefuture.org). We have over 1500 volunteers around the world, ready to help you get a 3D printed device that would work for your son, at no charge to you. To get the process started, just fill out our information gathering form here: goo.gl/lW1uX6 Someone from the e-NABLE Matching Team will then help to find an appropriate e-NABLE volunteer (maybe even in your local area) to assist.

@alanhong5897 10 лет назад

Hi margareth margoth , I sent a message to Filipe about this, but I thought it would be good to ask you too. Do you have a picture of your son's hand? Filipe mentioned that the thumb was lost.

@margarethmargoth 10 лет назад

Alan Hong My son lost his hand and has only the thumb, Philip doing the prosthesis him, but I am part of an association that takes care of developing technology for amputees (Adsta) and I'm an amputee who has just lost every hand thumb, for that I was interested in your project, you have the entire normal hand, just missing the thumb, we need the tutorial Adsta can print, thanks waiting contato..abraço

webapp is no longer available, can you help me with that?

@3duniverseOrgWelcomesYou 5 лет назад

There's updated guidance for determining device size from photos here: enablingthefuture.org/resources-2/e-nable-device-sizing/

@3duniverseOrgWelcomesYou 5 лет назад

Also, did you look here? It looks like the download is still available: physlets.org/tracker/

@carltarder2193 8 лет назад

how do i use webapp.e-nable.me/ if I need to build a raptor reloaded hand or is that not possible?

@3duniverseOrgWelcomesYou 8 лет назад

The Handomatic web app currently only supports the Raptor Hand 1.0 (original design) and the Cyborg Beast. You'll need to download the Raptor Reloaded STL files from Thingiverse and scale them as needed. There are instructions available along with the files on Thingiverse. www.thingiverse.com/thing:596966
