A method for establishing a comprehensive
pipe rack information
database comprises steps as follows: S1,
point cloud data of an
underground pipeline network are acquired through a
laser scanning instrument; S2,
data registration and transferring are performed; S3,
noise data are rejected; S4, the
point cloud data without the
noise data are subjected to data
thinning processing; S5, a pipeline surface model is established; S6, a pipeline model is drawn; S7, pipeline information is extracted; S8,
system configuration parameters are read, extracted
pipe point and pipeline data are checked, and checked results are listed on a table according to the mistake type; S9, a two-dimensional
planar graph of a pipeline is drawn, the type and the material of the pipeline and the
pipe diameter information are marked, and finally, a pipeline result map is obtained; S10, the pipeline result map, a three-dimensional diagram of the pipeline model and the two-dimensional
planar graph of the pipeline are stored in the
database. According to the method, base establishing for underground pipelines can be rapidly completed, and the pipe rack data are vectorized.
