Abstract

Reports research into the use of sonar in determining the size, position and orientation of underwater cylinders. The triple scan method of cylinder location is used, with range data being pre-processed to increase the system accuracy and robustness. The performance of the three different data enhancement algorithms investigated is compared by testing on both real and synthetic data, showing the best results to be obtained by a heuristic ellipse fitting algorithm
