Abstract
The invention provides a navigation system and a navigation method. The navigation system comprises a portable navigation device and a head-up display. The navigation system is mainly characterized in that the portable navigation device generates a first navigation image and a second navigation image according to an electronic map and navigation information and displays the first navigation image, and the second navigation image is output to the head-up display so as to project the second navigation image onto a windshield, wherein the first navigation image is a more detailed and complicated image; and the second navigation image has more obvious navigation information or icons. The system can reduce the risk of accidents caused by distracting to identify the navigation images on the windshield of drivers.
Description
[technical field]
The present invention relates to a kind of navigational system and method thereof, particularly a kind of navigational system and method thereof that allows the HUD projection have the image of tangible navigation information.
[background technology]
At present, guider is general gradually, and more and more drivers rely on guider the required information of travelling is provided, for example cartographic information, the route planning that arrives the destination and navigation information or the like.Guider can be divided into vehicle navigation device and personal navigation apparatus generally.Vehicle navigation device is that vehicle is built in the vehicular computer in just when dispatching from the factory, and its screen and operation-interface are disposed in the vehicle in the control desk.And personal navigation apparatus is a portable electronic devices, and it is not connected with vehicular computer, and the user uses in the time of can or driving on foot the time.Yet present guider is all not good or screen is too small by the screen position, causes the driver when driving, sight line must be removed travel and watch guider, even the identification navigation information of must diverting one's attention, increase the risk factor of driving virtually.
Cause is in view of the caused problem of guider, some vehicle just is provided with a HUD (Head-Up Display in driver's seat the place ahead, HUD), in order to the projection navigation information on windshield, allow the user watch navigation information, reduce the unexpected possibility that takes place while driving from windshield.In addition, along with personal navigation apparatus (Personal Navigation Device, PND) more and more general, more and more users wish that PND can combine with HUD, so the screen image that some HUD also can receive PND projects on the windshield again.Yet, the many of the screen of PND can show more detailed electronic chart and many navigation informations, so complicated image projecting not only can't be assisted the driver to windshield, allow divert one's attention navigation information on the identification image of driver on the contrary, and then increases the unexpected possibility that takes place.
Because above-mentioned every problem addresses the above problem in order to take into account, the inventor proposes a kind of navigational system and method thereof based on research and development and many practical experience for many years, with implementation and the foundation as the above-mentioned shortcoming of improvement.
[summary of the invention]
In view of this, purpose of the present invention is to provide a kind of navigational system and method thereof exactly, to solve the problem that combines the projection information too complex that produced because of HUD with portable navigation device.
The invention provides a kind of Portable navigational system, it comprises a portable navigation device and a HUD.Wherein, this portable navigation device produces one first navigation image according to an electronic chart and a navigation information, produces one second navigation image according to this first navigational system and a processing handling procedure again.At last, again this second navigation image is sent to HUD.And this HUD is just in order to receive and the described second navigation image of projection.
In addition, the present invention proposes a kind of air navigation aid, and it comprises the following step: at first, produce one first navigation image according to an electronic chart and a navigation information.Then, navigate image to produce one second navigation image according to a rules of arrangement and first.At last, the second navigation image projecting is gone out.
Compared with prior art, it is more detailed and complicated image that the present invention is provided with one first navigation image, one second navigation image is navigation information or the icon image that more obviously navigates, and by this system, can reduce the risk that navigation image on the identification windshield meets accident of diverting one's attention because of the driver.
