Embodiment Construction
[0033] The invention provides a method for fitting the mileage and geographic space coordinates of pipeline body data to solve the technical problems in the prior art that the direction of the pipeline cannot be accurately calibrated and the location of defects.
[0034] The technical solution in the embodiment of the present application is to solve the above-mentioned technical problems, and the general idea is as follows:
[0035] Establishing the alignment database of the pipeline specifically includes: modeling the data objects with geospatial coordinates or mileage and establishing the association relationship between each data object; after the alignment database is established, the detection results and Aligned data objects are respectively added to the alignment database; hard point selection and hard point alignment are performed on the data objects contained in the alignment database, wherein the data objects in the alignment database include two types, the first data...
