DIY Book Scanner

This is great! Now I have some thing to recommend for people without a Raspberry Pi.

dtic, I am continually astounded by the great things you are able to do with AutoHotKey.

Now that enough pieces of the laser scanning technique are working, I can now see a viable end to end workflow. ## Rig: The rig is essentially a copy stand with attached lasers and lighting. A single camera faces down on the page with two lasers pointing straight down at adjustable positions. The la...

Thanks, gerard. I will want to look into that when I get this more integrated into Spreads. Since I am running on a Raspberry Pi, it is always best to offload the work onto the client if possible. :) I've also been working with Pocketsphinx to see how well that works. The nice thing is that it is ve...

I've figured out a way to almost entirely get rid of the foreshortening problem. Compare these images: Original: https://files.app.net/wh25n7-cn Uncorrected: https://files.app.net/wh225MxY- Height-factor=2.0: https://files.app.net/whs2tEK5g The new height-factor is a command line option that you can...

Voice recognition has come a long way in recent years and it is very accurate when the vocabulary is small. There are open source packages for voice controlled projects on the Raspberry Pi. This would free hands for page flipping. And you could either avoid a foot pedal altogether or repurpose your ...

Thanks to Chrisoph's (guitarguy) help, I have managed to refine the laser scan postprocessing technique quite a bit. The current method will automatically detect left and right page boundaries, deskew, and dewarp all pages. The only hints you have to give it are to tell it whether it is an odd or ev...

I've been working with Cristoph over the last few days, and we have some very promising leads on new methods. The most promising method at the moment lets us dewarp pictures in a manner that is completely content-independent. Take a look at this paper: http://users.iit.demokritos.gr/~bgat/3337a209.p...

This is why I mentioned SpreadPi. A Raspberry Pi card is very cheap and then you can control the entire process from a windows computer and download a zip at the end.

FYI, the best way to do this is now the Spreads program by jbaiter. Using spreads, everything is controlled from your computer. The cameras will capture images at the press of a button and those images will be automatically downloaded and stored in the right order. Go check out the Spreads sub-forum...

I have some Python code that ostensibly implements the method in that paper. But it produces crazy results and I don't understand the math well enough to know what I am doing wrong. Send me a PM with your email address and I can send you the code I have if you want to look at it. For testing, you ca...
