Situational awareness systems and methods
Example systems and methods are described that help increase the situational awareness of a user of a helmet, such as a motorcycle helmet. One or more cameras are physically coupled to the helmet, where each camera includes a lens and an associated image sensor. Each camera is configured to generate a video feed, which is presented to a user on a display. The video feed represents a field-of-view around the helmet, and may be projected onto a surface, such as the visor of the helmet, thereby enabling enhanced situational awareness for the user of the helmet.
1. A helmet comprising:
a first image sensor configured to generate a first video signal located along a first optical axis;
a second image sensor configured to generate a second video signal located along a second optical axis that is substantially parallel to the first optical axis, wherein the second image sensor includes an image sensing surface and is disposed such that the image sensing surface is oriented in a direction that is opposite to the orientation of an image sensing surface of the first image sensor;
a first lens assembly optically coupled to the first image sensor, wherein the first lens assembly projects a 180-degree field-of-view onto the first image sensor;
a second lens assembly optically coupled to the second image sensor, wherein the second lens assembly projects a 180-degree field-of-view onto the second image sensor;
one or more processors configured to independently process the video signal generated by the first image sensor and the video signal generated by the second image sensor, wherein the first video signal includes the 180-degree field-of-view projected by the first lens assembly on the first image sensor, wherein the second video signal includes the 180-degree field-of-view projected by the second lens assembly on the second image sensor, wherein the one or more processors independently correct for any distortion present in the first video signal to generate a first corrected video signal, and wherein the one or more processors independently correct for any distortion present in the second video signal to generate a second corrected video signal; and
a projection system that projects the first corrected video signal and the second corrected video signal onto a visor of the helmet for viewing by a user, wherein the first corrected video signal offers a 180-degree field-of-view, and the second corrected video signal offers a 180-degree field-of-view to the user.
2. The helmet of claim 1 , wherein the combination of the first corrected video signal and the second corrected video signal presents a 360-degree field-of-view to the user.
3. The helmet of claim 1 , wherein the user can select either the first corrected video signal or the second corrected video signal for viewing.
