Instead of using an actual scanner, use this program to extract document content from a photograph, removing all the background, and adjusting the document perspective. Who needs scanners, anyways?
This is still a work in progress.
./simplescanner <source image> <dest image>
You will need
- CMake v2.8
- OpenCV (works on OpenCV v3.1.1, but the code itself should work on v2.4, but I haven't tried)
- C++ 11
Once those are installed, outside the cloned code, create a build folder, and then:
$ cmake -DCMAKE_CXX_FLAGS=-std=c++11 <path to source folder>
$ makeAnd you should be all good to go.
