A pipeline position detection method based on 3D scanning

Abstract

The invention relates to a pipeline position detection method based on three-dimensional scanning, which includes selecting a plurality of control reference points on the wall, setting target marks at the same time, measuring the coordinates of the control reference points in the construction coordinate system, and scanning the position of the pipeline , and scan the reference point target at the same time, convert the scanned data into the construction coordinate system, intercept the scanned data of the pipeline, sort the pipeline data according to the wall, select a section of cross-section data according to the requirements, and separate the inner data of the pipe and the data of the inner side of the pipe according to another column of data For the data outside the pipe, calculate the coordinates of the center of the pipe from the assumed theoretical radius to obtain the actual value of the center and radius of the pipe. The invention not only can obtain accurate detection results, but also solves the problem of pipeline position inspection in nuclear power construction, especially when the pipeline volume is particularly large, and improves the safety, flexible detection, and convenient measurement of pipelines located at high altitudes. Help meet the quality control needs of on-site construction.

Description

A method of pipeline position detection based on 3D scanning technical field The present invention relates to the technical field of nuclear power plant construction, in particular, to a kind of pipeline position based on three-dimensional scanning Detection method. Background technique [0002] There are many plant equipment and pipelines in nuclear power plants, and many pipelines are reserved for walls and bottom plates. During construction, inspections are frequent and measurement times are frequent. The wall is high, the construction site conditions are poor, the inspection is inconvenient, the safety performance is not easy to guarantee, and the inspection takes a long time, which is not conducive to The optimization of the construction period cannot ensure the quality of the work. SUMMARY OF THE INVENTION In view of the above-mentioned problems, the object of the present invention is the problem that the background technology proposes, provides a kind of using...
