Abstract
At the narrow space in the dry dock, it is extremely difficult to measure the three-dimensional (3-D) surface profiling of the ship. Therefore, the authors considered to draw on our knowledge and experience for the 3-D laser beam scanning equipment. Because the 3-D laser beam scanner is a three-dimensional noncontact surface profiling equipment, this is much help to the effective work for the measurement of 3-D shape on the ship with an ease never before possible. Furthermore, the latest in 3-D laser beam scanners are becoming increasingly cheaper and more powerful. In this case, we had to use the 3-D laser beam scanner at the narrow space in the dry dock. Therefore, we adopted the way which is the measurement of 3-D surface profiling of the ship at the ground points on the parallel line to the keel line. This is an effective work procedure to get the information of the 3-D surface profiling of the ship.
