Abstract

The utility model relates to a navigation device taking a 3D arrowhead as an intersection turning informatory sign, which comprises a CPU unit, a GPS unit, a map database, a path turning data storageunit, a path drawing data storage unit, a turning sign model storage unit (i.e. an arrowhead model database) and a map generating and 3D arrowhead drawing unit. When a turning point shows in a screen,a corresponding 3D arrowhead is obtained from the arrowhead model database and then the 3D arrowhead is moved to an intersection needing display; the size of the 3D arrowhead increasingly becomes larger as the intersection becomes closer; and the direction pointed by the 3D arrowhead is consistent with the turning direction of the intersection.

The utility model content

Technical problem to be solved in the utility model provides a kind of with the guider of 3D arrow as crossing reminding turning sign.

For solving the problems of the technologies described above, of the present utility model with the guider of 3D arrow as crossing reminding turning sign, comprise: CPU element, being used for of linking to each other with CPU element determined the GPS unit from car end position, what link to each other with CPU element is used for according to destination and the described map data base that the vehicle ' guidance information is provided from car end position, and vehicle speed sensor that links to each other with CPU element and the angular-rate sensor that is used for determining direction of traffic, it is characterized in that: CPU element also is connected with the route turning data storage cell that is used for providing according to described vehicle ' guidance information corresponding route turning information, the path describing data storage unit that provides corresponding path to draw information is provided, be used for providing the turn marking model storage unit of corresponding turn marking according to described route turning information, generate and the 3D arrow is drawn the unit by the map of drawing described turn marking and drawing corresponding 3D arrow, and the touch-screen that when turning point is in screen, is used for dynamically showing the 3D arrow by little and the earth.

Further, described CPU element also is connected with the RAM that is used to store ephemeral data.

Further, described CPU element also is connected with the voice suggestion generation unit that is used for prompting the place ahead direction information when screen displaying 3D arrow.

The utility model has positive effect with respect to prior art: (1) is of the present utility model with in the guider of 3D arrow as crossing reminding turning sign, CPU element is obtained corresponding route turning information according to the vehicle ' guidance information from the route turning data storage cell, from the describing data storage unit of path, obtain corresponding path then and draw information, and obtain the coordinate of next turning point by guidance information, when turning point is in screen, from rotation arrow model bank (being turn marking model storage unit), obtain corresponding 3D arrow, then this 3D arrow being moved on to the crossing that needs to show locates, and along with drawing near of this crossing, this 3D arrow is also changed by little and the earth gradually; And 3D arrow direction and the crossing direction of turning round is consistent when showing.

Embodiment

(embodiment 1)

See Fig. 1-4, the guider of present embodiment comprises: CPU element 1, being used for of linking to each other with CPU element 1 determined the GPS unit 2 from car end position, what link to each other with CPU element 1 is used for according to destination and the described map data base 4 that the vehicle ' guidance information is provided from car end position, and vehicle speed sensor 5 that links to each other with CPU element 1 and the angular-rate sensor 7 that is used for determining direction of traffic, it is characterized in that: CPU element 1 also is connected with the route turning data storage cell 6 that is used for providing according to described vehicle ' guidance information corresponding route turning information, the path describing data storage unit 11 that provides corresponding path to draw information is provided, be used for providing the turn marking model storage unit 12 of corresponding turn marking according to described route turning information, generate and the 3D arrow is drawn unit 9 by the map of drawing described turn marking and drawing corresponding 3D arrow, and the touch-screen 3 that when turning point is in screen, is used for dynamically showing the 3D arrow by little and the earth.Described CPU element 1 also is connected with the RAM10 that is used to store ephemeral data.Described CPU element 1 also is connected with the voice suggestion generation unit 8 that is used for prompting the place ahead direction information when touch-screen 3 shows the 3D arrow.

See Fig. 2, CPU element 1 is obtained corresponding route turning information according to the vehicle ' guidance information of user preset or generation automatically from route turning data storage cell 6, from path describing data storage unit 11, obtain corresponding path then and draw information, and obtain the coordinate of next turning point according to guidance information, when turning point in the screen of touch-screen 3 when (being in the indication range), draw unit 9 by map generation and 3D arrow and draw described turn marking and draw corresponding 3D arrow, show the 3D arrows by touch-screen 3 at last;

See Fig. 3, after CPU element 1 is obtained the routing information that the next one turns to crossing (being turning point), CPU element 1 is obtained corresponding turn marking model according to described route turning information from turn marking model storage unit 12, CPU element 1 is calculated described the turning to and the road angle of crossing that turn to, then with turn marking rotation and move to this crossing, and turn marking carried out perspective transform, draw at last and show the 3D arrow.

See Fig. 4, after obtaining the routing information that turns to the crossing in CPU element 1, obtain the path that turns in the marquee, and path-line is extended to face by certain width, simultaneously planar arrow is moved to turning point, and angle is rotated arrow by path, then face is extended to 3 D stereo by certain altitude according to the arrow model, describe each face of 3 D stereo at last, thereby draw corresponding 3D arrow.
