[0002] Pipes are common materials in engineering construction, and pipeline reconstruction is common in engineering reconstruction. When arranging pipeline reconstruction or laying, it is necessary to determine the size of the pipeline. The size of the pipeline includes the location data of the pipeline, the outer diameter of the circular cross-section, and the three-dimensional data of the center of the pipeline. Among them, the center data of the pipeline cross-section is the most difficult to measure, especially when the on-site environment of the engineering reconstruction is relatively complex and it is difficult to use the measurement equipment.

[0003] Traditional prisms can display their own three-dimensional data. Based on this, the applicant designed a convenient measuring device, using the principle of three points forming a circle and concentric circles to ensure that the center of the circle formed by the three prism centers is the same as the center of the pipe. In this way, the spatial three-dimensional data of the center of the pipe can be obtained by calculation. Utility Model Content
