How could you use your digital camera to digitize and scan text?
Including doing OCR on them?
I am a student trying to save money on copies you need from a libraries. (Aren't digicams expensive enough already?) Sometimes papers are not that good anyway and you only need sections of them. I know there are ways to tell an OCR software to read a file from the file system, but I haven't found an end-to-end, comprehensive explanation about how to do this, and AFAIK there is no web site that consistantly lists features in comparison charts Most hits I found after googling for it were about using cameras primarily to take pictures, which might be not the case for the large amount of students that would basically use them as scanners. I tech monkey I know was telling me about high res imaging cameras, which come with a PCI card to plug into a PC so that 'you get what you see' functionality which is useful for running the OCR right and keep working at the same time. Could you explain to me at least your experience with such things? What are the involved issues? I guess all cameras are not created equal. Which ones are best for text scanning? Those best for B&W Mode or gray scale? I think this is pretty much doable with current commercial gadgets, but I just don't know how. |

The suitable rig would be a copy stand. Once that's in place then it would
be a piece of cake. In article , says... In om (Albretch) wrote: Including doing OCR on them? Since the free copy of ABBYY "Fine Reader Sprint 4.0" which came with my old scanner can do it, I'm assuming that any OCR software can be pointed at digital photos of pages of text and convert them. I just grabbed my Canon A60 (a 2MP camera), photographed a piece of paper on my desk, downloaded the resulting JPEG and OCRd it. The parts of the page that were in reasonable focus and not too distorted perspective-wise came out pretty clean. If you had a suitable rig with a camera mount and some lights, you should get decent results. -- Bert Hyman St. Paul, MN |
