creating a single 3D image from 2D jpgs

[miazanoapte]

Unfortunetly I have no photo of the actual object, that's why I need to reconstruct it from these photos heh.

 

Not really, what you see is the object from above (through the laser gun so to speak), you're actually seeing "into" it. I don't have sides of the object, just "slices" of it as the laser passed through. Think of it like a huge loaf of bread that's been cut in equal thin slices. Stack 'em all next to each other and you've got the loaf again.

 

Where the light travels deep you've got bio-tissue. Where it doesn't you've got either a piece of bone or one of the screws.

were looking at bone? now im really lost:)

 

If you do the procedure i mentioned you can make a top surface of your part. before you import jpegs create layers for each of your jpegs. This is a big task for someone who has never worked with cad before. how much time do you have to do this?

"were looking at bone? now im really lost"

 

So was I even though the word "mandible" had come up a couple of times. But now I'm interested as I used to work in an operating room as a surgical technician.

 

Is this mandible from a human or an animal? Why all the interest in it and what is this really all about? I know there is some very sofisticated 3D imaging equipment and software used within the medical community that can produce some spectacular images of tissue and bone.

Sorry for not giving all the details from the beginning but i didn't want to include aything not relevant to the problem (which remains basically the reconstruction of a 3D OCT scan from 2D photos). But if it helps...

 

So an optician tagged me next to him and got me doing all sorts of things (me being a student around there and all that).

 

There was a demonstration at which he assisted, with a mandible of a young dog with two screws bolted through which was used as a probe for an OCT scan with a laser.

 

The probe has been destroyed, he only has a collection of photos left. Now he asked me to take these scans and recreate the mandible with them, but simply the shape is irelevant, it must also hold the information gathered in the scan (with the light going through it and everything). He took a picture of computer-screen with the image those guys had created with a specialised software, but sadly i don't have it.

 

In those photos you have a laser hitting the gum, the bone and the screws and basically you see how far the laser "penetrated" those materials. This isn't really true however, because of the geometry of the picture, what you actually see there is imprecise.

 

But it could be solved if somehow i'd manage to reconstruct the probe and see exactly what has happened.

 

Edit: i'm not really pressed by time, but i hate not being able to cope with things heh. I have a while to think things over and mayhaps find a solution.

 

Oh, I forgot, I don't know, perhaps "jaw" is more suitable in English then "mandible". Sorry if it misguided you.

well it would be a long process but from the jpegs you could create an image in general, however relating all of the scan"depths" would be impossible as i see it. You really need to look into some software that handles grey scale imaging.

You're not going to be able to accomplish the task with AutoCAD. Period.
