Raspberry Pi and optical mouse ==> hand held scanner
|
|
|
|
This project emulates one you can find here:
|
|
|
|
http://spritesmods.com/?art=mouseeye
|
|
|
|
which converts a cheap optical mouse in to a hand held scanner.
|
|
|
|
It is very crude - for my mouse the scanner is 16x16 pixels and covers
|
|
an area less that 1mm square, so you can imagine how hard it is to
|
|
get an accurate and complete image.
|
|
|
|
You could improve things by using a better quality mouse, I think, because
|
|
this real cheap one tends to forget to report movement every now and then.
|
|
Also, if you were in to image processing you could stitch the 16x16 pixel
|
|
images together much more accurately than by relying solely on the movement
|
|
reported by the mouse itself.
|
|
|
|
Anyway I can across a link to the spritemod site and fancied giving a
|
|
go. If you want to try, then go to the spritemod site for the details
|
|
of how to connect to the mouse sensor. My mouse has an A2030 sensor
|
|
which has the same interface as the ones mentioned on the spritemods
|
|
page.
