Abstract
A smart helmet includes a heads-up display (HUD) configured to output graphical images within a virtual field of view on a visor of the smart helmet. A transceiver is configured to communicate with a mobile device of a user. A processor is programmed to receive, via the transceiver, calibration data from the mobile device that relates to one or more captured images from a camera on the mobile device, and alter the virtual field of view of the HUD based on the calibration data. This allows a user to calibrate his/her HUD of the smart helmet based on images received from the user's mobile device.
Claims21
A smart helmet comprising:
- a heads-up display (HUD) configured to output graphical images within a virtual field of view on a visor of the smart helmet;
- a transceiver configured to communicate with a mobile device of a user;
- and
- a processor in communication with the transceiver and the HUD, and programmed to:
- receive, via the transceiver, a facial structure model of a face of the user created by one or more captured images from a camera on the mobile device,
- determine calibration data based on the facial structure model, and
- alter the virtual field of view of the HUD based on the calibration data.
(canceled)
A system for calibrating a heads-up display of a smart helmet, the system comprising:
- a mobile device having a camera configured to capture images of a face of a user;
- a smart helmet having a heads-up display (HUD) configured to display virtual images within a virtual field of view on a visor of the smart helmet;
- one or more processors configured to:
- create a facial structure model of the face of the user based on the captured images;
- determine one or more facial characteristics of the user based on the facial structure model;
- determine an offset value for offsetting the virtual field of view based on the one or more facial characteristics;
- and
- calibrate the virtual field of view based on the offset value to adjust a visibility of the virtual images displayed by the HUD.
One or more non-transitory computer-readable media comprising executable instructions, wherein the instructions, in response to execution by one or more processors, cause the one or more processors to:
- capture one or more digital images of a face of a user via a camera of a mobile device;
- create a facial structure model of the face of the user based on the captured images;
- determine a facial feature of the face based on the facial structure;
- transmit a signal from the mobile device to a smart helmet, wherein the signal includes data relating to the facial feature of the face;
- receive the signal at the smart helmet;
- and
- calibrate a virtual field of view of a heads-up display of the smart helmet based on the received signal.
