In general, for ship-building, construction methods are modularized into large blocks and produced by moving them through a super-large crane to complete them. Large blocks have the effect of reducing the total work, but when the actual block is joined, there are more errors than the actual design due to deformation due to welding, corrosion, heat, and suffer a lot of difficulties when joining the block.

Precise block measurement is a high priority, and several methods have been announced. In the early days of Joseon, blocks were surveyed in pairs of two, one by one, and then the methods used in civil engineering were applied due to the development of surveying techniques. However, the above methods have been used by many people and airborne, so recently, the laser distance measuring method is used.

As a method using a laser, there is a method using a laser guide for measuring feces (Patent No. 2001-0001524), a method of surveying using a non-targeted light wave measuring instrument (Patent No. 2005-0090173), and the like.

Conventional methods have a disadvantage in that it is not very effective in the domestic shipbuilding environment having a large number of blocks and a narrow location environment because a certain space between the target and the measuring device is required.
