Paper Abstract

In the paper, an on-line detection system for ships in lock of is presented. The system has three functions: (1) Judging whether there are ships in lock in time; (2) Detecting whether ships cross the forbidden lines in lock; (3) Observing whether there are ships out oflock. Therefore, the system not only maintains the normal and fast working of lock,but also ensures safety of lock. The detection method is based on the optical flow of gray-level probability.
