Augmented reality head-up display for overlaying a notification symbol over a visually imperceptible object

A method for displaying graphics upon a windscreen of a vehicle, the method comprising:

• receiving, by a controller, a plurality of detection points that indicate a presence of an object from one or more non-visual object detection sensors and image data from one or more cameras;
• comparing the plurality of detection points with the image data of an environment surrounding the vehicle to identify a visually imperceptible object located in the environment;
• in response to identifying the visually imperceptible object, determining a notification symbol that signifies the visually imperceptible object;
• and
• instructing, by the controller, a graphic projection device to generate the notification symbol upon the windscreen of the vehicle, wherein the notification symbol is overlaid at a position upon the windscreen where the visually imperceptible object would normally be visible, wherein the graphic projection device includes a projection device that creates an excitation light that creates the images projected upon the windscreen.

An augmented reality head-up display system for displaying graphics upon a windscreen of a vehicle, the augmented reality head-up display system comprising:

• one or more non-visual object detection sensors to detect objects in an environment surrounding the vehicle;
• one or more cameras that capture image data of the environment surrounding the vehicle;
• a graphic projection device for generating images upon the windscreen of the vehicle, wherein the graphic projection device includes a projection device that creates an excitation light that creates the images projected upon the windscreen;
• and
• a controller in electronic communication with the one or more non-visual object detection sensors, the one or more cameras, and the graphic projection device, wherein the controller executes instructions to:
• receive a plurality of detection points that indicate a presence of an object from the one or more non-visual object detection sensors;
• compare the plurality of detection points with the image data of the environment surrounding the vehicle to identify a visually imperceptible object located in the environment;
• in response to identifying the visually imperceptible object, determine a notification symbol that signifies the visually imperceptible object;
• instruct the graphic projection device to generate the notification symbol upon the windscreen of the vehicle, wherein the notification symbol is overlaid at a position upon the windscreen where the visually imperceptible object would normally be visible;
• determine a rate of approach towards the visually imperceptible object by the vehicle;
• and
• adjust at least one visual parameter of the notification symbol based on the rate of approach towards the visually imperceptible object by the vehicle.
