large cool.. i actuall made a optical maser scanner 12 years back and getting the edge in of the optical maser to give a sharp edge was a pain and the generated scan always came out jagged edge.. your edge sleuthing seems to give a smooth edge. i am tempted to try it but make a bit Sir Thomas More sophisticated using a platform raising up and down in milk. have you tried and true other whitened dyed liquids that wont spoil afterward a while?

Instead of adding salt how about victimisation table salt insteaqd of a liquad? have the salt drain out like in an hourglass.

thanks for sharing. very clever glide slope.

how many viewing angles are required if there are overhangs? do u postulate to take a set of pictures from different angles for over hangs? how does this work?

thanks

This is a really clever mind. I enjoyed seeing what you've finished.

The comments on the experient post you connected to are fascinating, and address very much of the thoughts I had while considering your take on this method acting. Worth a look for anyone curious :)

Nice to see the direction you've appropriated this. Thanks for communion!

chilly! that's really nice inspired idea for similar process this just príncipe blow muy mind, thnks forma share. share-out is caring

The cheapest not the just about cheap I think.

So as good as in 2007

A little besides manual - spooning milk in the scanned container and clicking to take the image every now and then. GotMesh is zero more expensive and much less work for scan wear't you think ?

Often, the simpler ideas are the best. The conception bestowed here is smashing and quite economical compared to alternatives for 3D scanning. It can also make up very impressive.

There are a couple of issues to solve to clear it flatbottom to a greater extent versatile. None are show stoppers, as seen in previous comments. They retributive need further thought.

Someone mentioned merely making several scans, changing the object's position; fetching more time but very effective at addressing odd shape objects and keeps whole cost down. At worse, 6 scans should be needed - each face of a 'block'. Doing more would imply overhangs (hidden spaces / voids). Still thinkable with approach taken Here, just more work to scan and then sew together consequent meshes.

The use of a clear-cut liquid with a floating layer of (near) opaque "oil", whether it's fetching the images from the top or bottom (swimming proof television camera required) address problem of the milk going bad at some point, cost and recycling of the liquid, ... downbound to contrast with targe to scan past changing the coloration of the floating "oil". There is always the possibility of dynamic the colour of the object itself - promptly level of (removable) paint (ex: matte black to contrast with shiny white milk). It needs to personify thin none pooling, so it doesn't change the object shape during the scanning process.

Giving the use of goods and services of liquids, the object to be scanned of necessity to comprise water validation and 'solid' (not leaky) so it does non absorb the liquid, specially i which spoils. Depending on the object, solution would be to give a sealer. It power also help colour and/or return the glare out, contingent the sealer being used.

The exercise of a very fine pulverise would introduce need for shaking to keep surface level flat (a consistent 'body of water line' tracing the objective) Merely it would also require a infantile fixation method for the object (invalidate object from moving around !)

The effect of the objects shape on the Z settlement, as indicated away others, can be addressed in several ways. The simplest could be to register the height of liquid's surface over clock. It would then be sync'ed with the time seal of the images. A simple approach power be using the OSD (on screen display) concept. That is, to have a read-out of the height within the field of the camera which so gets processed by the software to 'read' the presentation (unadjustable location and height) and 'rigid' the Z consequently. The declaration of the readout would have to be as nice as a 3D printer's Z axis. I suspect a float rigged to some sort of whole number micrometer ? It might not be 'cheap' enough. There power live a way to do this purely a machine display : the float lateen-rigged to a right 'swayer' positioned nonconvergent to the camera's field. As the float follows the liquid's surface, it moves a marker along the ruler; marking is heights enough contrast that package can pick it up and forecast position. The camera's resoluteness, along with the marker shape/contrast, becomes the limit for the precision of the calculated Z. There mightiness not represent even a need for a ruler - just a reference point and knowing the camera's declaration.

The GotMesh 3D scanning concept bathroom be a very viable low toll overture to get precise net of exactly about any liquid imperviable(ed) objects of any size. Naturally, I'm not ready to dip my car to drive a 3D model of it, but it would represent possible (and out there, there's a person thinking close to it now - LOL)

Way to hold out YenFre, kudo's to you. Fantastic idea !

I think I will try this to scan the body/shell of my model (1/10 scurf) monster truck. Melanise the shell using something like Pasti-Dip paint (it can exist peeled off 'easily' without damaging), scan it with GotMesh, and then alter the resulting mesh to make my ain variant. Sequent 3D model could live CNC'ed to make a modeling to thermo form a new tailored shield. The hardest part, for me, would to paint the body in some catchy formula. Tada... I conclusion up with a selfsame unique monster hand truck at negligible monetary value !

I conscionable Gotmesh'ED ! And I'm loving it. ;))

Have you tried a compounding of super fine backbone and vibration to even the "layers"? Just a intellection that occurred when I came across this build. I will follow trying this when life story settles down again.

No I have non but that is a really operative idea. I will give to judge it. Thank you for commenting and throwing that impermissible there for everyone.

do you have a telecasting its hard to understand this stairs

Non yet. I will try to post one by this Mon. Thank you for the interest group.

Nice work, military personnel, i love that first-rate-simple thought!

However, if i understand it right, then i see another combined only right smart less problematic flaw side by side to the "nates half"-thing: the z-axis vertebra-reference. it looks like you constantly secrete the milk by its natural flow, which first follows a somewhat complex diferential equation ascribable the constantly changing altitude and related insistence of the liquid.

Second yet if id did flowing constantly, the liquid height would change faster where the object is large, consuming more of the volume, so the Milk River-volume in that height region is far faster than where the object is small. Of course, this effect might be negligible when using large boxes and small objects As you do.

What i lack to say is if you wish to bugger off a precise and undistorted image in the z-direction, you would have to mention from each one image of the time lapse not to the time itself, merely to the actual liquid height at that time. Idk exactly what the expenses of employing a precise dissolved height measurement would be, only it would make this wonderful machine even put to work in accordance to physically correct principles!

And another thing i'd like to remark: I would suggest using soy Milk River, because it is superintendent cheap and easy to make yourself in large amounts and flat easier if its not intented for human consumption!

Now i hope i dont come about like super-self-important, but these were the thoughts that struck me right after "oh god how impressive is this thing?!!".

> on the nose what the expenses of employing a precise liquid height measurement would make up,

You could always employment another camera giving a side view of the milk level (either against a ruled scale, OR just using OpenCV to find the level of the milk in the picture). Then it would comprise a case of taking pictures with the side-view photographic camera to encounte the right time to actuate the main camera.

Or, you might do it on a single camera if you can use a mirror (angular) to get a look on at the milk tied in the same field-of-view as the configuration image. Then IT becomes a case of taking (and throwing away) images until the Milk River level has touched by 1 "unit" of depth, and retaining that image, before repeating the process.

Ingenious scanning method :)

Thank you for the comment. Yes, the preciseness of the Z-summit could certainly be improved victimisation another camera. A mirror is a great way to nonmoving use one camera. Thank you for unselfish. To boot the camera could keep taking pictures but the script (political program) could align them supported their position instead of wait to take pictures based connected the tiptop.

Thank you for the comment. You bring up a very good point I did not think of that the shape of the object will vary the surface area cross-part and therefore drainpipe rate. We did taste to account for the difference in rate of flow from the height the of milk only we did non account for it in terms of the object itself. I wish continue to thing about a root to that. Also, I leave definitely endeavour soy Milk. I am glad you enjoyed this project.

I wouldnt use Milk River, but maybe SALT or baking soda

Thanks for the notice suggestion. I have tried both and from my experience milk works finer as the liquid to be drained must be completely opaque even at very lank thicknesses but I may rich person not added enough salt or baking soda.

Clever idea. I dont know much chemistry but could you float a thin bed of oil e.g. and and then ice-cream soda an multicoloured LED that would single colour or maybe flourese that thin bed. Then you could economic consumption the same liquid and change the colouration for maximim contrast with the item you are scanning. Then you could need an underwater picture at the same time - the underwater camera mightiness not work if lower fluid not transparent.
