1it cost me less than 10 euro
2it can go about 8 with 9 pages per minute . 500 pages per hour in best cases.
3every page has almost the same ankle with the light source . (in 2 cameras diybookscanner this is stable )
4you can calibrate the perfect ankle between glass and camera lens with the mirror trick. (in 2 cameras diybookscanner this is also stable )
5i am using a audio trigger from selfie stick . The bluetooth trigger has compatibility issues after a lot a pages or if for any reason i stop scan when i begin i have connect them again and recalibrate glass-lens ankle.
6 you can change between glass -lens the distance and keep it stable .
if you finish the scanned book , have already a usb cable connected only in smartphone. then connected on a laptop and take the capture pages to check them. that's why if you put out the smartphone from the selfie stick smartphone case , copy pages to your pc you will need to put it back and capture the missed pages. so the distance or the position of the lens will change .check exactly where you put your smartphone every time.( in 2 cameras diybookscanner use sd card cable to avoid that) .
also you can find which is the best glass-lens distance with abbyfinereader. there is a command detect optimal resolution. the more it gives you the better the image. if you have a 2 camera diybookscanner the cropped images even or odd should have the same size. my images usualy are 510 or 540 suggested dpi i can go better (640 ) but i have light problems and need to change other camera position . so i let it just more that 500 and cropped pages on the same size for the context of the page. scan tailor experimental rescale them on the same size but odd or ever pages will have darker letters if you have much different lens-glass distance on your cameras. more than 300 suggested dpi gives you he same ocr results . more than 500 suggested dpi looks the same with for your eyes .
7 you can change perfect where the camera centre . before you start to capture a book change this distance with the screws , so lens focus on the centre of the context. use white tape on the glass on the top and the bottom of the page and try to keep it there all the pages .
8 try the smartphone case from the selfie stick be stable. if it turns centre of the content where lens focus change , glass-lens distance change
9 in a 80 pages book i have one blurred pages .
10 you can move it in librarys but try a dark environment to scan
11most important . try not to watch the light source while you scan. put a paper so you don't have light in your view. dude seriously is kind of trippy to watch a light source all the time.
i became kinda obsessed with distance and mirror ankles because if you fix the mechanic part which is the challenge .
-how to stabilize yours camera in the perfect position and how to find that- you spend less time for a better digitalize of your books.
its took me 6 steps to edit images with abbyfinereader . its the only program with the command straight text line massively .now i use only scan tailor to edit images. that means for 600 pages 40 minutes less for the processes of the images. i wanted command straight text line inside scan tailor . but the solution its mechanic . thank you whoever you are guy or girl with the mirror trick.
