A Vessel Flow Detection System based on Laser Sensors

weiqing Li, Youtao Yang, Shihong Shen


A system using two laser sensors for vessel flow detection was introduced. Mathematical morphology on ship contour detection was studied and vesselâ??s contour was reconstructed based on geometric space projection, vesselâ??s width threshold filtering and connected graph merging. Also, the necessity of vesselâ??s contour reconstruction is verified by experiments. A data fusion method based on two laser sensors was researched for vesselâ??s length detection, which using spatial adjustment and data correlation to calculate the speed, and to estimate the length of a vessel. Finally, a vessel flow detection system was built and worked fine.
