The method of connecting the middleware model of the pipeline connection with the pipeline at both ends in the 3D scene

Abstract

The invention provides a method for achieving butt joint of a pipeline connection middleware model and pipelines at the two ends in a three-dimensional scene. The method comprises the steps that 1, a to-be-processed point dataset of the pipelines is obtained on a pipeline plane of the three-dimensional scene; 2, the point dataset is judged according to situations, and the pipeline connection middleware model of the angle type needing to be selected is obtained; 3, a to-be-processed point dataset is judged according to the situations, and the rotation angle of the pipeline connection middleware model is obtained; 4, the results obtained in the step 2 and the step 3 are stored in corresponding layer datasets, and butt joint of the pipeline connection middleware model and the pipelines at the two ends is conducted. Accordingly, butt joint of the pipeline connection middleware model and the pipelines at the two ends can be accurately achieved in the pipeline plane of the three-dimensional scene.

Description

technical field [0001] The invention relates to a method for realizing the connection between a pipeline connection middleware model and pipelines at two ends in a three-dimensional scene, in particular, selecting the angle type of the pipeline connection middleware model on the pipeline plane of the three-dimensional scene and rotating the model to a corresponding angle for matching with the pipeline connection middleware model. The method of docking the two ends of the pipeline. Background technique [0002] In the 3D scene, when the pipe network data is imported into the application system, there are two-way, three-way and other characteristic points in the connection points between the pipelines, and in the 3D scene, there are also directions, rotation angles, etc. And the connection angle of the two pipelines. If one of the above three conditions is wrong in the 3D scene, what is displayed in the system is also wrong. Such as figure 1 Shown is the result of errors af...

AI Technical Summary

Problems solved by technology

[0004] When the operator adds the pipeline connection middleware model to the 3D scene, because the initial alignment direction of the pipeline connection middleware model is basically horizontal and horizontal, it is not accurately connected to the pipeline, but deviates somewhat, which results in The display error is very ugly
