Our business has field workers collect thirty-question free response forms from program participants at remote locations. Forms are standardized with identically-sized boxes (we will provide the form that is used and can modify it if necessary), and participants are identified by a sticker applied to the top of the sheet that contains a QR code that uniquely identifies the participant. We cannot expect that the stickers will be perfectly aligned, only that they will fall completely within a predefined region. We need a server-side solution that will allow field workers to upload pdfs of the answer sheets to our server and will then read the QR code and capture images of the thirty boxes and store them in a folder on our server with a unique name for each image. Our in-house programmers will handle all further processing from there. Because the pages will be scanned, the answer boxes will not be perfectly aligned in all cases, so the software will need to be able to find the answer boxes on the page and capture the full box (and ideally very little beyond the borders of the box). The software should be written in PHP if possible so our programmers can perform ongoing maintenance as we make changes to our form in the future. Attached is a copy of the form we are currently using.

Hello, I have gone through your given details and also reviewed your PDF.. The problem with scanning manually is there will be lot of variations withregard to angles the document is scanned at and also registration.. So the only solution is to make a program that search the regions and captures them.. Such program can be made but I need some examples of filled documents scanned to see the variation before givingyouidea for time and price. Could you please send me 5 or more scanned images from a filled PDF to review and get back to you with my offer. Thankyou

Hello Project Manager, I am an expert programmer and I have written several scripts that process PDF documents. I can develop a PHP/MySQL solution through which your participants can upload PDF documents and further processing is carried out on the server. Best regards, John.

If you could upload your sheets in JPEG format, the whole process would run much more efficiently. This task is basically a matter of graphic data processing, and that can be done much better over a graphic format like JPEG. Then we could easily locate and read the QR code, capture the answer boxes and store them again as JPEG files in a folder on your server. This is not difficult in itself, but it's very computational intensive because graphic processing involves checking hundreds of tausends of pixels and that is yet for a standard processor a heavy load, that's why we should try to avoid performing additional format conversions. PHP adds besides that an overhead due to the interpretation, but is indeed at the server the most practical solution nowadays, so we would try to optimize the code as much as possible letting it anyway clear enough to allow for easy maintenance in the future. The whole could be ready to test in no more that two weeks. Regards The Bramfeld Team
