US Patent 10564127 Augmented reality visualization for pipe inspection

A defect visualization system includes an augmented reality display system to display an image representing a defect, such as missing metal, in a ferromagnetic material when a user gazes at a portion of the ferromagnetic material hosting the defect, based on magnetic field data provide by a magnetometry system, thereby facilitating locating the defect and replacing magnetometers after the defect has been repaired, even if location references originally present on cladding material are lost or destroyed during the repair.
