Abstract: Aiming at the problem of self-localization for the mobile robot, a new infrared landmark localization module of embedded mobile robot is proposed. The module uses a single matrix initial calibration algorithm and camera initial calibration method to calibrate the camera before the process of localization. Experimental result shows that this module is effective on the embedded processors, and the precision of position localization is in the range of millimeter, the angle localization is less than 6°.
