Microfiche CAD scanning

Hello, I would like to know if some of you have been confronted with using microfiche, and have found a way to digitally extract the plans that are on it?

I found a reader (second-hand at 50€) but foudéze is complicated  to find something (about 110 plans on a card and fortunately I only have 4).

 

 

Hello

Maybe scanning companies allow you to digitize your microfiche?

Otherwise, with a scanner pushing the result to the maximum, it doesn't give anything?

Or with a camera and a macro photo?

The company that scans takes 2000€ per sheet.... gulp.... and gives them to you in pdf

The scan is not great, and I was told about a kind of magnifying glass to place on the scanner

To illustrate my point, here is a macro photo taken with my phone: with a good camera, you should be able to do even better!

Zoom in on the big drop at the top to see the quality!

I think it's an idea but to be taken with a lit background to bring out the white lines from the black background.

It reminds me of my board for PCB layers with a camera stand a bit like in the expert on TV lol

What are microfiche? ^^

James Bond brought you plans of the USSR!!

Do you have a DSLR (lens camera) available?

Because you can use any lens, even a basic 18-55 lens, by returning it with this very inexpensive adapter: http://goo.gl/YQ4IY5 for making impressive macro.

With microfiche in front of a light source (neon, or window), and a little patience, it's quite doable!

Bond my name is James Bond lol

So for information, microfiche is transparent sheet of paper in a format of 11 by 15 on which a multitude of plans are engraved. 

So I got some data from a caterpillar traxcavator 922A (and no it's not Russian but rather from  the other side) with all the detailed assembly plans of this wheel loader from December 1978

on 4 sheets I have about 400 plan and assembly instructions

 

Macro photography is not the best solution if used alone. It is necessary to have a translucent light surface to get the information out of the negative

And with a video projector that you try to set to zoom in as much as possible?

(I say that, I don't say anything) ;p

@Joss the video projector is very good when you have the image, but there the problem is already to extract the image.....

Oh, I understood that you only wanted 4 of the 110 shots!

Indeed, if you want all the shots, the macro photo solution will be very tedious!

yes, there are readers on leboncoin for 50 euros, but you can only display, but not scan!

Not really a practical solution!

It's huge your "lenses for macro" PL.

 

I didn't know, do you think it exists in universal? For the moment I only have a bridge and so I'm a little restrained...

Hello

Have you tried this.

Good luck.

@Bart @Hors-topic

I don't think it's compatible with your bridge because on a bridge, you can't remove the lens!

On a DSLR, you use the lens upside down!

@ christian, it's the same text as my link so there aren't many solutions

Well, I did a little research.

- Either you have your microfiche on your pc so there, you just have to convert them to dxf or other via a converter.

 

-Either you have microfiche physically, and then you need a special scanner or go through an annex company.

 

You can always try to tinker with your scanner to zommer in the middle, then run a trait recognition.

 

A link that may interest you: http://www.algolab.com/r2v.htm (convert any image to dxf. not tested)

 

What format are your sheets? (I'm a novice in this, but a brain of + is not too much =) )

@bart, they are about 11mm by 15mm wide (it's American format) 

For the moment I have found only used microfiche readers from garages (but I don't know what the size of the cards is in France)

there is a printer viewer for 150€ but the printer is defective....

otherwise the special cannon scanner used at 1000€ (it hurts to invest this price in an old thing to consult old plans)

I have to find a viewer and then with a camera take a picture.

this one could be processed by the software you indicated previously

What about a slide scanner? Can't it work?
