Among the present invention, the user is when using the GPS onboard navigation system, navigating instrument can provide the overall style of 3D three-dimensional bridge (such as more points of interest in gateway such as large-scale Pan Qiao, the extra large bridges of mistake), and for the client generates entering of bridge and withdraws from the path of navigation of road, the real-time animation that shows simultaneously this section path of navigation, the broadcasting speed of the animation of this section path of navigation and user's road speed are synchronous, so that the client is like a cork by complicated bridge.
Application scenarios of the present invention is below described.
At first, on the navigation map product, according to the actual conditions at scene, each key element of drafting 3 D three-dimensional bridge model and the road related with bridge, thus be used in conjunction with map vector data.By collection in worksite photo (comprise on-the-spot number of track-lines, car letter, bridge just concerns, enters and withdraw from road relation), so that 3D three-dimensional bridge model and actual bridge are consistent, south point mates to the west of carrying out with data ground, gives the longitude and latitude corresponding with data for the southwest point of model after the coupling.
Then, navigating instrument calculates path of navigation by latitude and longitude coordinates, and generation and the user synchronous animation of speed of driving, the use so that the user navigates.Guiding enters and withdraws from the road by the navigating instrument setting during user, and optimum path is calculated by latitude and longitude coordinates by the navigating instrument system, and generates when car travels with the synchronous animation of vehicle speed and guide.When the client in when driving, behind the navigating instrument path planning, system can choose a more excellent path for the client.Simultaneously, by bridge the time, bridge model can call in system, and is corresponding for the path that the user selects with navigating instrument according to the longitude and latitude that extracts bridge model, show the animation by bridge with the user of driver visual angle simulation with all or part of navigating instrument window, assisted user passes through bridge.
Simultaneously, can pass through the frame number broadcasting speed of the animation of running speed control simulation, on the path of navigation that system generates, each section longitude and latitude point one to one that is complementary with map datum is arranged, longitude and latitude in actual longitude and latitude point by the car process and the data, judge the longitude and latitude that garage passes through, thereby so that the broadcasting pictures of animation and running speed are synchronous.
The present invention has following beneficial effect: (1) provides the 3D stereoscopic model of the bridge that coincide with the scene, and each that can intuitively understand bridge complex enters and withdraw from the three-dimensional situation at crossing; (2) provide by what latitude and longitude coordinates generated and enter bridge and withdraw from the path of navigation of bridge, and generation and the car synchronous animation of speed that travels, the intelligent navigation path of using by bridge as the user, thus easily provide a more intuitive intelligent navigation by the large bridge of complexity for the user.
The above is preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from principle of the present invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
