Abstract
A system for calculating and visualizing a position of buried assets during a buried asset locate procedure in a target area includes an electromagnetic locate device (ELD) including electromagnetic antennas configured for sensing an electromagnetic (EM) field emanating from a buried asset at a target area, and an augmented reality system comprising a camera, a display, inertial sensors for measuring motion and distance moved, and processors configured for reading camera and sensor data, calculating motion and distance moved, generating a 3D model representing the target area, generating a 3D vector field representing the EM field emanating from the buried asset, calculating a position and type of the buried asset based on the 3D vector field and the 3D model, creating an object in the 3D model that represents the buried asset, and rendering video of the target area and the position and type of the buried asset.
