1. A method of providing a display for an operator of a vehicle, said vehicle having a right boundary, a left boundary, a video camera, and a ranging device, comprising:

  • a. providing a video display, including a left side, a top, and a right side, wherein said video display displays images from said video camera on said vehicle;

    b. providing an arch metaphor, extending from said left side of said video display, over said top, to said right side of said video display;

    c. displaying ranging data collected by said ranging device on said arch metaphor, wherein,i. said ranging data is dividing into ranging sectors,ii. each of said ranging sectors is correlated to an arc sector on said arch metaphor,iii. a range for each ranging sector is correlated to a color selected from a predefined color scale,iv. said ranging data is displayed on said arch metaphor according to said correlated arc sector and said correlated color;

    d. providing a right clearance indicator movable along said arch metaphor, with a position of said right clearance indicator along said arch metaphor being determined by a first amount of clearance between a projected right boundary of said vehicle and a first object that is nearest to a right side of said vehicle; and

    e. providing a left clearance indicator movable along said arch metaphor, with a position of said left clearance indicator along said arch metaphor being determined by a second amount of clearance between a projected left boundary of said vehicle and a second object that is nearest to a left side of said vehicle;

    f. wherein said position of said right clearance indicator is determined on said arch metaphor byi. providing a central axis extending outward from said vehicle in a forward direction,ii. providing a projected right boundary extending forward from said right boundary of said vehicle,iii. of those ranging sectors lying to the right of said central axis, determining a closest point that is closest to said ranging device,iv. passing a first range vector arc through said closest point on said right of said central axis,v. determining a right boundary intersection lying at the intersection of said first range vector arc and said closest point on said right of said central axis,vi. determining a right boundary vector passing from said ranging device through said right boundary intersection,vii. using said right boundary vector to control movement of said right clearance indicator along said arch metaphor;

    g. wherein said position of said left clearance indicator is determined on said arch metaphor byi. providing a projected left boundary extending forward from said left boundary of said vehicle,ii. of those ranging sectors lying to the left of said central axis, determining a closest point that is closest to said ranging device,iii. passing a second range vector arc through said closest point on said left of said central axis,iv. determining a left boundary intersection lying at the intersection of said second range vector arc and said closest point on said left of said central axis,v. determining a left boundary vector passing from said ranging device through said left boundary intersection, andvi. using said left boundary vector to control movement of said left clearance indicator along said arch metaphor.
