Not sure if this will help - https://aws.amazon.com/rekognition/

Using computer vision may provide a good enough result for this use case. An interesting approach would be to segment the book piles and bulk scan the spines. There are projects that already tackled this problem:

Won't be as accurate as barcode scanning, but will be definitely less time consuming.

One of these days I need to write my essay titled "Rubbish has no SKU". I've seen a few of these, and the basic minimum difference between "pulp waiting to happen" and "bookshop" is basic shelving. Different shelves by category: fiction vs non-fiction and their subdivisions. Within the shelves, alphabetise. Now it's possible for browsers to actually find things. When you put them on Amazon this will also help find th…

At a local LP shop, they had a sign saying "If you misshelve a LP, you might as well steal it, at least someone will listen to it" (approximate translation). Shelving in instead central to many specialty shops!

Yes, but there is something to be told for wading through mountains of junk to unearth something notable, I think many book nerds connect to that feeling.

While I largely agree with your sentiment, I'd like to note that alphabetizing only assists those who know what they are looking for.

In a bookstore, this is a virtue. But we appear to be dealing with a book barn. Perhaps the patrons of book barn have not wandered in by accident while searching for a bookstore :)

For OP: I think you might be better off photographing the ISBN and then using a service or script to do a lookup and associate that with a cover and title. Various editions might not have their covers recorded in a database, and titles will give many dupes, but an ISBN will uniquely identify a book.

Additionally, OCR'ing stylized text is problematic. I wouldn't expect easy reading of covers, particularly of used books.

That's fantastic. I was after a similar solution and after playing with OpenCV, I can see how they put the pieces together.

Annoyingly, I was trying to scan multiple books in charity shops, when one of my favourites started putting their own stickers directly over the barcode (when it existed).

It may very expensive in time and resources to scan it all even if it is just the covers. You need to work out how long it takes to fetch a book from the barn or container, flatten/unbind if necessary, scan the cover, rebind, and put back. Then multiply by how many books...

I worked at a small startup in the early 2000s that somehow got massive contract to digitalise a Middle Eastern Oil & Gas company's very very extensive documentation library. We had an e-learning product where you could use a scanner to digitalise a printed book into online documentation.

Demos of scanning a book or two was really impressive. So surely scanning more than a million books/manuals/charts will be just as easy. Not quite.

Think we calculated it would take years as the bottleneck is the manual unbinding and re-binding before and after scanning. Scale that to a million and it was not the 2 months project initially forecasted. Buying more scanners and hiring more local staff scaled that part horizontally and improved the speed but still a long project.

However the client "forgot" to pay us for a few months, the bank and our accountants forgot to check and we went bankrupt soon before we really got started. Though at least I got a trip to the Middle East for a few weeks.

The challenge is, if the catalogued book is not immediately associated with where to find it if retrieving it later, all is in vain...
