Augmented reality visualization of underground pipelines using geospatial databases and KM markers

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• identifying, using an augmented reality (AR) system, one or more kilometer (KM) markers that are nearest a location;
• superimposing, by the AR system, virtual representations of the KM markers onto a real-time displayed scene of the location captured by a camera of the AR system;
• obtaining, by the AR system using KM marker information of a user-selected KM marker, fiducial information of a fiducial marker of a pipeline associated with the user-selected KM marker, wherein the fiducial marker is identified according to a standard shape recognizable by the AR system;
• obtaining, by the AR system using the fiducial information, segment coordinates of the pipeline, wherein the segment coordinates are based on spatial coordinates of the fiducial marker;
• determining, by the AR system, a relative position of the pipeline to the real-time displayed scene captured by the camera, wherein the relative position of the pipeline is determined based on a direction in which the camera is pointed, coordinates of the camera, and the segment coordinates of the pipeline;
• and
• superimposing, by the AR system, a three-dimensional (3D) model of the pipeline onto the real-time displayed scene captured by the camera.

A computer-implemented system, comprising:

• one or more processors;
• and
• a non-transitory computer-readable storage medium coupled to the one or more processors and storing programming instructions for execution by the one or more processors, the programming instructions instructing the one or more processors to perform operations comprising:
• identifying, using an augmented reality (AR) system, one or more kilometer (KM) markers that are nearest a location;
• superimposing, by the AR system, virtual representations of the KM markers onto a real-time displayed scene of the location captured by a camera of the AR system;
• obtaining, by the AR system using KM marker information of a user-selected KM marker, fiducial information of a fiducial marker of a pipeline associated with the user-selected KM marker, wherein the fiducial marker is identified according to a standard shape recognizable by the AR system;
• obtaining, by the AR system using the fiducial information, segment coordinates of the pipeline, wherein the segment coordinates are based on spatial coordinates of the fiducial marker;
• determining, by the AR system, a relative position of the pipeline to the real-time displayed scene captured by the camera, wherein the relative position of the pipeline is determined based on a direction in which the camera is pointed, coordinates of the camera, and the segment coordinates of the pipeline;
• and
• superimposing, by the AR system, a three-dimensional (3D) model of the pipeline onto the real-time displayed scene captured by the camera.
