Description
Technical field
The present invention relates to a kind of method for building up of model, particularly a kind of method for building up about marine oil facility three-dimensional model.
Background technology
In the process of marine oil industry development growth, being accompanied by construction scale of projects progressively enlarges, the work in every relevant with engineering also becomes increasingly complex, the cost that engineering project is managed with management also promotes rapidly thereupon, be the most significantly engineering information collection, processing, store and utilize the lifting of cost.The Chinese Sea oil is through nearly 30 years development, investment construction assets reach hundreds billion of offshore oil and gas fields, but offshore oilfield was all gone through for several times more than 80% at the labour platform and was renovated at present, all there is the not enough phenomenon of record that renovates in a lot of the transformation, and caused many incomplete problems of engineering information data that renovate.Because of of the remote past, the design documentation at initial stage also has disappearance in various degree to part at labour platform itself in addition, therefore all brings a lot of inconvenience to setting up with renovating of later stage at the model of labour platform.
In collection and storage to the technical information of engineering, at present Main Problems is: 1, current current new edition data standard and coding rule all be based on newly-built, in the engineering information data of Jianping platform, but for using as a servant platform, particularly of the remote past at the labour platform, there is some difference for its design specifications and new edition, and owing to participate in the background difference of design side, also there are differences and contradictions the coding rule of design document in itself to part at the labour platform.Therefore, the importing in labour platform engineering information faces compatible problem.2, the phenomenon of the enlarging of offshore platform ubiquity and new and old combination, therefore, also must need in the engineering information system engineering information Information integration of new legacy platform to be got up to store and call, and the problem of the old and new's part combination will inevitably appear in this process, and this problem is not only the combination for model, also comprises engineering information combination in larger scope, because new legacy platform data is processed division of labor difference, rule is different, and especially the docking of three-dimensional model will face series of problems.
Lose comparatively serious old production vessel and chemical plant for data, prior art adopts the outdoor scene restored methods such as 3 D laser scanning to make it true reappearance usually, but also there are the following problems for the method: 1, because offshore oil facility volume is usually larger, utilize the data volume of the offshore oil facility model that 3 D laser scanning method scanning obtains huge, not only computing machine itself there is strict requirement, and directly offshore oil facility integral body is carried out reverse modeling by magnanimity point cloud and need to spend long time; 2, the digital model itself of setting up by reverse-engineering only has surface information, without any engineering attribute, institute's beared information amount seldom and can not customized development, so so that the actual application value of reverse three-dimensional model have a greatly reduced quality, its function rests on more model and browses and represent, for deeper application, then have too many difficulties to cope with maintenance work such as renovating of offshore platform.
Summary of the invention
For the problems referred to above, the purpose of this invention is to provide a kind of modeling speed fast, take a short time, and can be for the method for building up of the marine oil facility three-dimensional model of partial data information be provided at labour platform engineering facility.
For achieving the above object, the present invention takes following technical scheme: a kind of method for building up of marine oil facility three-dimensional model may further comprise the steps: 1) adopt three-dimensional laser scanner repeatedly offshore oil platform to be carried out entire scan; 2) adopt reverse engineering software that the cloud data that each scanning obtains is carried out respectively pre-service; 3) adopt reverse engineering software that the marine cloud data of multi collect is spliced, obtain to reflect the mass cloud data set of offshore platform integral; 4) the original design drawing of employing offshore oil platform is set up the original three-dimensional model of offshore oil platform in Forward modeling software; 5) the mass cloud data set is imported in the existing Forward modeling software by corresponding plug-in unit; 6) mass cloud data set is mated with the original three-dimensional model of offshore oil platform align, the structure of three dimensional point cloud and original three-dimensional model generation difference is carried out mark; 7) to each structure of mark, according to the cloud data of relevant position, in Forward modeling software, carry out the three-dimensional digitalization model that modeling obtains offshore oil platform; 8) store three-dimensional digitalization model, and set up the three-dimensional model that meets the offshore oil platform present situation according to three-dimensional digitalization model.
Described three-dimensional laser scanner adopts come card HDS6000 scanner.
Described Forward modeling software adopts PDMS software.
Described reverse engineering software adopts come stuck point cloud software.
It is by the LMI interface of PDMS software come card CloudWorx plug-in unit to be installed that described step 5) imports to the mass cloud data set in the existing Forward modeling software by corresponding plug-in unit, by described come card CloudWorx plug-in unit, utilize the Cyclone software of come card that the mass cloud data set is imported in the PDMS software.
The present invention is owing to take above technical scheme, it has the following advantages: 1, the present invention is owing at first adopt laser scanner in building or built the offshore oil facility of finishing and scan, then the design drawing according to original offshore oil carries out modeling to original offshore oil facility, and by cloud data and original offshore oil facility three-dimensional model are compared, the part that difference occurs is carried out modeling by cloud data, obtain the three-dimensional entity model of complete reflection offshore oil equipment, therefore the present invention not only can carry out fast quick-recovery to the three-dimensional model of existing offshore oil facility, obtain the accurately three-dimensional entity model of existing offshore oil facility, and provide complete electronic data for follow-up offshore oil facility keeps in repair and transforms.2, the present invention is because a part-structure for the offshore oil facility that changes carries out three-dimensional modeling according to a cloud, therefore do not need a large amount of cloud datas is carried out modeling, requirement to computing machine reduces, can finish modeling in common computer, so that method practicality of the present invention is higher.3, the present invention adds relevant engineering attribute by original offshore oil facility drawing to the part-structure of the offshore oil facility set up by cloud data, not only so that offshore platform have an intuitively visual effect, and can renovate and maintenance work provide complete design considerations to offshore oil facility follow-up.4, the present invention is by on the three-dimensional model basis of original offshore oil facility, and the accuracy that the mode of checking by a cloud has improved data makes to obtain the present situation that three-dimensional model more meets the offshore oil facility.The present invention can be widely used in the Chinese Sea oil in the renovating of labour platform facility.
