Editing Bookscanner (section)

=== Software ===

(See also: [[Book Scanner Software]])

The scanning is handled by a [https://github.com/danyq/diybookscanner Python script] that uses gphoto2 to connect with the cameras and displays images of the scanned pages in an HTML view. Three USB ports are required for the monitoring computer: One each for the two cameras, and one for the keyboard or triggering mechanism. Post-processing is handled with [http://scantailor.sourceforge.net/ ScanTailor], an [https://gist.github.com/WD-42/7595388 OCR script using Tessaract], and [https://github.com/thisisparker/bookscanning various other scripts].

Live View is obtained through a utility called Darktable. It supports "tethering mode". It may even be possible to use Darktable as a complete book assembly application. Not sure yet.

Alternative for liveview from a python library

There is a toolkit called [http://chdk.wikia.com/wiki/CHDK Canon Hack Development Kit] ([[CHDK]]) which might be useful for cameras not supported by gphoto2.

There is a firmware upgrade for Canon DSLR cameras like the 5D Mk II called [http://www.magiclantern.fm/ Magic Lantern] which is popular. The supported models of cameras have a high resale value.
