DISTORTION AND PERSPECTIVE CORRECTION OF VECTOR PROJECTION DISPLAY
First Claim
1. Method to represent graphical images upon a transparent windscreen head up display of a vehicle describing an operational environment for the vehicle, the method comprising:
- monitoring data describing critical information in the operational environment for the vehicle;
monitoring a location of a viewpoint of an operator of the vehicle;
determining a desired graphic to represent the critical information in a viewing space based upon the data and the viewpoint;
transforming the desired graphic in the viewing space into a projected graphic in a projection space defined by the surface of the windscreen;
transforming the projected graphic in the projection space into patterns of projected light in a projector space; and
generating commands to a graphics projection system based upon the patterns of projected light.

Abstract
A method to represent graphical images upon a transparent windscreen head up display of a vehicle describing an operational environment for the vehicle includes monitoring data describing critical information in the operational environment for the vehicle, monitoring a location of a viewpoint of an operator of the vehicle, determining a desired graphic to represent the critical information in a viewing space based upon the data and the viewpoint, transforming the desired graphic in the viewing space into a projected graphic in a projection space defined by the surface of the windscreen, transforming the projected graphic in the projection space into patterns of projected light in a projector space, and generating commands to a graphics projection system based upon the patterns of projected light.

11. Method to represent graphical images upon a transparent windscreen head up display of a vehicle describing an operational environment for the vehicle, the method comprising:
-
performing a first pass computation cycle, comprising; determining a viewing space for a desired graphic; transforming the desired graphic from the viewing space into an intermediate projected graphic in a virtual display plane located proximate the windscreen; and transforming the intermediate projected graphic in the virtual display plane into a projected graphic in a projection space defined by a surface of the windscreen; performing a second pass computation cycle, comprising; transforming the projected graphic in the projection space into patterns of projected light in a projector space; and generating commands to a graphics projection system based upon the patterns of projected light.

12. System to display graphical images upon a windscreen of a vehicle describing an operational environment for the vehicle, comprising:
-
the windscreen comprising a transparent windscreen head up display; a vehicle sensor system monitoring conditions in the operational environment; an enhanced vision system system manager; monitoring the vehicle sensor system; determining critical information warranting display upon the windscreen based upon the monitored vehicle sensor system; and generating display requirements based upon the critical information; an occupant viewpoint sensing system; a graphics system; monitoring the occupant viewpoint sensing system; monitoring the enhanced vision system system manager; determining a desired graphic to represent the critical information in a viewing space based upon the display requirements and data from the occupant viewpoint sensing system; transforming the desired graphic in the viewing space into a projected graphic in a projection space defined by a surface of the windscreen; transforming the projected graphic in the projection space into patterns of projected light in a projector space; and generating commands to a graphics projection system based upon the patterns of projected light. - View Dependent Claims (13, 14, 15)
