The invention has the beneficial effects as follows: the present invention, by setting up the large data platform of precision, realizes the database purchase of accuracy data.By setting up parent ship database, completing the large data reserve in basis of follow-up ship and marine engineering product, carrying out the significant data reference source of accuracy control work (comprising reversible deformation setting, precision surplus, compensation enlarging etc.) as follow-up ship.
Accompanying drawing explanation
Fig. 1 is the structural drawing of large ship of the present invention and extra large work construction accuracy data storehouse system.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Refer to Fig. 1, large ship of the present invention and extra large work construction accuracy data storehouse system, comprise accuracy data storehouse 1, accuracy data database management module 2, precision measure module 3, subscriber interface module 4, Registration of Measuring Data module 5 and explanation module 6.
Subscriber interface module 4 realizes system and intercoms mutually with user, guides user to control modules.That is: subscriber interface module 4 connects accuracy data database management module 2, precision measure module 3 and explanation module 6, realizes mutual.
Precision measure module 3 accepts the control of subscriber interface module 4, measures sectional construction, total group, carries each stage accuracy data, and be transferred to accuracy data storehouse 1 and accuracy data database management module 2.Accuracy data storehouse 1 stores each precision measure data and the Precision Theory data of large ship and the construction of extra large work.
Accuracy data database management module 2 connects accuracy data storehouse 1, realizes data acquisition, data retrieval and data maintenance.Concrete, accuracy data database management module 2 comprises: data acquisition module, data retrieval module and data maintenance module.Data acquisition module obtains accuracy data from accuracy data storehouse 1 and precision measure module 3.Data retrieval module detects accuracy data in accuracy data storehouse 1.Data maintenance module is safeguarded accuracy data in accuracy data storehouse 1.Subscriber interface module 4 shows the result that data acquisition module, data retrieval module and data maintenance module export.Thus in conjunction with ship building period, influencing each other and connecting each other in analysis precision database between each precision unit.Accuracy data storehouse consistance, accuracy and completeness are checked.Realize the management and utilization to precision and accuracy data storehouse.
Precision measure data in Registration of Measuring Data module 5 pairs of accuracy data storehouses 1 and Precision Theory data are mated, and particularly, after Registration of Measuring Data module 5 obtains boats and ships measurement data, corresponding geometric model is extracted in link model storehouse.The data type of analysis to measure cloud data, theoretical by the registration of Quaternion Method algorithm, slightly to begin registration based on model geometric feature, reduce the rotation translation offset error between measurement data point set and design point set, ICP iterative algorithm is utilized to complete the accuracy registration of segmentation feature data and design data, that automatically carries out measurement data and process model data slightly to mate and Optimum Matching calculates, and obtains the coordinate figure that measurement data points rotates translation, thus output matching result.
The matching result of no data collision is transferred to subscriber interface module 4 by explanation module 6, or is transferred to subscriber interface module 4 after having the matching result of data collision to clear up.
Above embodiment is used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, various conversion or modification can also be made, therefore all equivalent technical schemes also should belong to category of the present invention, should be limited by each claim.
