Abstract:	To enhance the digitalization level of shipbuilding, this study focuses on the construction methods and applications of digital shipyards. The design of different quantities and layouts of reference points is based on the dock's spatial dimensions, the principles of reference point arrangement, and the required measurement accuracy. An assembly coordinate system is established using the horizontal reference plane determined by the electronic level and the longitudinal movement direction of the assembly system equipment. A digital measurement process specification is developed based on the constructed spatial measurement field. Finally, using a specific ship structure model as an example, three typical application scenarios are introduced: segment assembly positioning measurement, total segment alignment positioning measurement, and structural internal equipment base positioning measurement. The construction of the spatial measurement field in the shipyard lays an important foundation for the subsequent creation of a digital shipyard. [ABSTRACT FROM AUTHOR]
