Assignee: KONINKLIJKE PHILIPS N.V.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 4:
5. An augmented reality (AR) based servicing guidance method comprising:
performing a first service call to service a medical imaging device undergoing service during the first service call, the medical imaging device comprising a transmission computed tomography (CT) imaging gantry, a positron emission tomography (PET) imaging gantry, a magnetic resonance imaging (MRI) device, a gamma camera for single photon emission computed tomography (SPECT) imaging, or a combination thereof;
during the first service call, recording video of the medical imaging device undergoing service during the first service call;
using a computer, authoring AR content including the operations of receiving user input at the computer identifying at least one location of interest (LOI) in the recorded video of the medical imaging device undergoing service during the first service call and performing computer vision (CV) processing to align AR content with the recorded video of the medical imaging device undergoing service recorded during the first service call including aligning a portion of the AR content with the at least one LOI;
performing a subsequent service call to service a medical imaging device undergoing service during the subsequent service call;
during the subsequent service call, and using (i) a server computer and (ii) a mobile device including a display and a camera, presenting the authored AR content to a service person performing the subsequent service call by operations including:
acquiring a live video feed of the medical imaging device undergoing service during the subsequent service call using the camera of the mobile device and transmitting the live video feed from the mobile device to the server computer;
using computer vision (CV) processing performed by the server computer, aligning the authored AR content with the live video feed of the medical imaging device undergoing service during the subsequent service call;
transmitting the AR content aligned with the live video feed of the medical imaging device undergoing service during the subsequent service call from the server computer to the mobile device; and
displaying on the display of the mobile device the authored AR content aligned with the live video feed of the medical imaging device undergoing service during the subsequent service call; and
using the electronic processor and the mobile device, performing a servicing preview by performing the CV processing to align the authored AR content with preview video substituted for the live video feed of the medical imaging device undergoing service during the subsequent service call produced by the camera of the mobile device and simultaneously displaying on the display of the mobile device both the authored AR content aligned with the preview video and the preview video displayed as an underlay of the authored AR content.
