DEVELOPMENT OF A THREE-DIMENSIONAL CO-ORDINATE MEASURING SYSTEM FOR LARGE STRUCTURES

Modern shipbuilding methods call for a high degree of accuracy to cope with the complicated design of large structural blocks. In practice it is difficult to embrace three-dimensional shape and size using conventional measuring equipment, owing to its poor reliability and accuracy. The authors describe the development of a three-dimensional measuring system using laser beams and a modified triangulation method. Examples of the success of the system when applied to the measurement of a block for a large ULCC are given. The advantages of the system are given and discussed. Order from BSRA as No. 49,457.
