A method for
dynamic data visualization and updating of
subsea pipelines integrating BeiDou positioning is disclosed, relating to the field of
marine engineering digitization and 3D
visualization technology. This method constructs a marine digital twin
data architecture consisting of a
perception layer, a data layer, a fusion layer, a model layer, and an
application layer. The
perception layer integrates BeiDou positioning terminals, pressure sensors, temperature sensors, and
sonar detection equipment deployed along the
subsea pipeline to collect pipeline position coordinate sequences, environmental parameters, and
seabed topography data in real time. The data layer standardizes, cleans, and encrypts multi-source heterogeneous data for storage. The fusion layer employs an adaptive
Kalman filter algorithm to tightly couple BeiDou positioning data and inertial navigation data to obtain
centimeter-level accuracy in the dynamic spatial position of the pipeline. By constructing a real-time fusion architecture of high-precision BeiDou positioning data and multi-source sensor data,
dynamic visualization updates and secure interaction of the
subsea pipeline's spatial position, operational status, and structural morphology are achieved.
