Problems solved by technology

[0003] The purpose of the present invention is to provide a method for converting three-dimensional data measurement of a ship based on a coordinate system to two-dimensional data measurement in order to solve the above-mentioned problems. By using the three-dimensional target as a reference, the part exceeding the standard of the product is corrected to reduce the risk of the product after welding. Cutting correction amount, reduce welding quality problems and deformation problems caused by secondary welding, and at the same time improve the simulation loading and application of the product in the segmented construction stage

Embodiment Construction

[0042] The present invention will be further described below in conjunction with examples.

[0043] The invention discloses a method for converting three-dimensional data measurement of a ship into two-dimensional data measurement based on a coordinate system, comprising the following steps:

[0044] (1) Determine the three-dimensional datum

[0045] Project the absolute reference onto each production station, and establish three-dimensional space coordinates at the production station;

[0046] The production station includes twenty rows of tire racks, each row includes twenty tire racks, and the distance between two adjacent tire racks is one meter;

[0047] Both the ECO-BLCOK analysis and the ECO-OTS simulation are carried out based on the reference point. The reference point cannot be adjusted under the current requirements, because it is to ensure the uniform precision control of the whole ship, reduce the cumulative deviation and realize the follow-up process optimizatio...

Abstract

The invention discloses a method for converting ship three-dimensional data measurement to two-dimensional data measurement based on a coordinate system. The method comprises the following steps: (1) determining a three-dimensional reference; (2) preparing a three-dimensional production station; (3) mounting a three-dimensional reference target; and (4) carrying simulation at a production station. According to the invention, problems can be found in time, later correction time can be shortened in segmented manufacturing time, measurement work and analysis work can be greatly reduced, field production efficiency is improved, and labor cost is reduced.

Description

technical field [0001] The invention specifically relates to a method for converting three-dimensional data measurement of a ship into two-dimensional data measurement based on a coordinate system. Background technique [0002] At present, in order to improve the segmentation quality, the shipbuilding industry conducts whole-process monitoring, and there are many difficulties and problems in the monitoring process. Among them, 3D data measurement is one of the monitoring methods, and at this stage, domestic large-scale enterprises are quite dependent on 3D data control methods. , and at this stage total station and analysis software are expensive, in order to reduce the equipment cost of shipbuilding enterprises and ensure the accuracy of product manufacturing, it has become the key research direction of the industry. Contents of the invention [0003] The purpose of the present invention is to provide a method for converting three-dimensional data measurement of a ship ba...
