Projecting location based elements over a heads up display
First Claim
1. A computer implemented method comprising:
- generating a three dimensional (3D) model of a real world scene within a specified radius from a vehicle, based on a digital mapping source of the scene;
associating one or more positions in the 3D model with respective location aware entities (LAE);
estimating a current view direction of a viewer in the vehicle; and
superimposing three-dimensional graphic symbolic indicators respectively representing the LAEs onto a windshield of the vehicle in specified positions selected according to the estimated current view direction of the viewer such that the viewer, the symbolic graphic indicator on the windshield, and the position of the LAE in the 3D model are substantially on a common line of sight of the viewer,wherein the three-dimensional symbolic graphic indicators comprise at least one three-dimensional direction arrow,wherein the arrows are superimposed on the windshield only some of the time, when considered needed by the viewer to identify a desired turn of the vehicle.

Abstract
Methods and systems for projecting a location based elements over a heads up display. One method includes: generating a three dimensional (3D) model of a scene, based on a source of digital mapping of the scene; associating a position of at least one selected LAE contained within the scene, with a respective position in the 3D model; superimposing the projecting onto a specified position on a transparent screen facing a viewer and associated with the vehicle, at least one graphic indicator associated with the at least one LAE, wherein the specified position is calculated based on: the respective position of the LAE in the 3D model, the screen'"'"'s geometrical and optical properties, the viewer'"'"'s viewing angle, the viewer'"'"'s distance from the screen, the vehicle'"'"'s position and angle within the scene, such that the viewer, the graphic indicator, and the LAE are substantially on a common line.

4. A system comprising:
-
a processor; and a projector configured to; generate a three dimensional (3D) model of a scene within a specified radius from a vehicle, based on a digital mapping source of the scene and associate one or more positions in the 3D model with respective location aware entities (LAE); estimate a current view direction of a viewer in the vehicle; superimpose three-dimensional graphic symbolic indicators respectively representing the LAEs onto a windshield of the vehicle, in a two dimensional (2D) specified projection area selected according to the estimated current view direction of the viewer, such that the viewer, the graphic indicator on the windshield, and the position of the LAE in the 3D model are substantially on a common line of sight of the viewer, wherein the three-dimensional symbolic graphic indicators comprise at least one three-dimensional direction arrow, wherein the arrows are superimposed on the windshield only some of the time, when considered needed by the viewer to identify a desired turn of the vehicle. - View Dependent Claims (5, 6, 7, 8)

9. A computer program product, the computer program product comprising:
-
a non-transitory computer readable storage medium having a computer readable program embodied therewith, the computer readable program comprising; computer readable code configured to generate a three dimensional (3D) model of a real world scene within a specified radius from a vehicle, based on a digital mapping source of the scene; computer readable cock configured to associate one or more positions in the 3D model with respective location aware entities (LAE); computer readable code configured to estimate a current view direction of a viewer in the vehicle; and computer readable code configured to calculate a position on a windshield of the vehicle of at least one three-dimensional symbolic graphic indicator associated with at least one LAE, wherein the calculation is based on;
the estimated current view direction of the viewer, such that the graphic indicator, and the LAE are substantially on a common line of sight of the viewer,wherein the three-dimensional symbolic graphic indicator comprises at least one three-dimensional direction arrow, wherein the arrows are superimposed on the windshield only some of the time, when considered needed by the viewer to identify a desired turn of the vehicle. - View Dependent Claims (10, 11, 12)
