libdots is a 2D localization library based on Anoto® technology. It is used to localize a camera-equipped device on a surface with a printed encoded pattern. It is written in pure c and has no external library dependencies other than libc. Tools to generate the dotted pattern and overlay it onto any PDF file is included (written in c++). Download link for the entire source achive can be found below.
It has been successfully compiled and tested on:
- The PIC32MZ1024ECG064 microcontroller, built with xc32 v1.34.
- Ubuntu 14.04, 15.04, 15.10
