Progress Report - January 2012

Good progress has been made on developing COLREGs-compliant path planning algorithms. Currently, modified forms of A* are being developed in addition to integrating the dynamics of various types of vessels.

A ship simulator package, 'Virtual Simulator' has been procured for training and generating videos to be used for obstacle detection purposes.

For obstacle detection, the hardware include a high-definition camera in conjunction with a laser range sensor. Standard background subtraction techniques along with Kalman filter based prediction algorithms are employed to estimate the current position of the obstacle and its projected position in the future.
