Method of displaying symbol information in vehicle navigation and its apparatus {METHOD AND APPARATUS FOR DISPLAYING SYMBOL INFORMATION OF CAR NAVIGATION}

The present invention relates to a technique for displaying symbol information in vehicle navigation. More particularly, when a display condition for a symbol of each landmark satisfies a preset 3D display condition, the symbol is selectively expressed as a 3D symbol. The present invention relates to a method and apparatus for displaying symbol information in vehicle navigation.

As is well known, a navigation device is mounted (or mounted) on a moving object, such as a vehicle, and its current position from global positioning system (GPS) satellites in the air via its internal or external GPS receiver. Receives a value (coordinate value) and displays various service information necessary for navigation, such as the current position of the moving object, the moving direction of the moving object, the distance to the destination, the current moving speed of the moving object, the driving route of the driver setting, and the optimum path to the destination. It provides a function for providing various service information necessary for driving (driving) of the vehicle.

In addition, the navigation device may allow the driver to easily recognize landmarks such as gas stations, airports, harbors, national parks, beaches, banks, department stores, convenience stores, schools, golf courses, amusement parks, fishing spots, restaurants, and the like. It provides a service that displays (displays) related 2D symbols and names on a monitor. Here, the 2D symbol for each landmark is generally expressed as a polygonal shape symbol of the same size.

Accordingly, the driver can effectively recognize what the landmark means, even if the driver briefly looks at the 2D symbols and names displayed on the monitor of the navigation device while driving.

However, the conventional method of expressing 2D symbols of the same size for each landmark only provides 2D symbols of the same size regardless of the importance or user preference of each landmark, thereby limiting the driver's visibility. I had to have.

In other words, when a specific landmark is expressed as a 3D symbol whose size is relatively larger than a 2D symbol according to the importance of the landmark or user preference, the visibility by the driver may be greatly improved. There is no suggestion on the concept of selectively expressing the symbols having.

Of course, all landmark buildings or regions displayed on the map may be considered to be constructed and displayed as a 3D model, but in this case, there is still a problem in securing visibility of symbol display according to importance or preference, and also the map Increasing the capacity of the data introduces another problem, where the speed of edge and symbol display is relatively slow.

According to one aspect of the present invention, when the navigation mode for displaying a travel route map information screen is executed on a monitor, the present invention provides a method of detecting occurrence of a landmark that is a symbol display target and symbol display when the landmark is detected. Checking whether a condition satisfies a preset 3D display condition, and when the preset 3D display condition is met, extracting a 3D symbol corresponding to the landmark from a storage block and displaying the same on the monitor; A symbol information display method in a vehicle navigation is provided.

According to another aspect of the present invention, there is provided a method of detecting a occurrence of a landmark that is a symbol display target when executing a navigation mode for displaying a driving route map information screen on a monitor, and when the landmark is detected. A process of checking whether a mark is a preset 3D display target, and a process of checking whether a symbol display condition for the landmark meets a preset 3D display condition when the landmark is the preset 3D display target And retrieving a 3D symbol corresponding to the landmark from a storage block and displaying the 3D symbol corresponding to the landmark on the monitor when the preset 3D display condition is satisfied.

According to another aspect of the present invention, when a storage block for storing 2D or 3D symbol information corresponding to each landmark and a navigation mode for displaying a driving route map information screen are executed, generation of a landmark that is a symbol expression target is performed. A landmark detection block for detecting a symbol, a 3D adaptive selection block for determining whether the landmark is a predetermined 3D expression target when the landmark is detected, and whether the symbol expression condition satisfies a preset 3D expression condition; When the preset 3D display condition is satisfied, the apparatus provides a symbol information display apparatus for vehicle navigation including an information extraction block for extracting a 3D symbol corresponding to the landmark from the storage block and outputting the 3D symbol on the monitor.

According to the present invention, when the occurrence of symbol display for a landmark is detected when executing the navigation mode, it is checked whether the symbol display condition for the landmark satisfies the preset 3D display condition, and the preset 3D display condition is satisfied. When the 3D symbol corresponding to the symbol is drawn out and displayed on the monitor, the visibility of the landmark by the driver (cognition) can be significantly improved.

1 is a block diagram of an apparatus for displaying symbol information in vehicle navigation according to the present invention;
2 is a flowchart illustrating a process of selectively expressing 3D symbols and 2D symbols corresponding to landmarks according to symbol presentation conditions when executing a navigation mode according to the present invention;

The technical idea of the present invention is that, unlike the above-described conventional method of expressing 2D symbols of the same size for each landmark, if the occurrence of the symbol display for the landmark is detected when executing the navigation mode, the symbol for the landmark Check whether the display condition meets the preset 3D display condition, and when the preset 3D display condition is satisfied, the 3D symbol (3D model or 3D animation) corresponding to the symbol is drawn and displayed on the monitor (display). By this means, the present invention can effectively solve the problems in the conventional manner through such technical means.

Here, the preset 3D display condition includes a map display angle (an angle between the map and the position of the eye looking at the map, which can be selected from an angle range of 0 to 90 ° C.) and the map scale factor. When the angle is at least greater than the preset reference angle and the map scale is at least greater than the preset reference scale, it may be determined that the preset 3D display condition is satisfied.

This is to minimize the case that the display angle is difficult for the driver to recognize the 3D symbol, or that the map is relatively large and the symbol is crowded to complicate or interfere with information transmission. That is, in the present invention, even if the landmark to be expressed is designated as the display of the 3D symbol, if the predetermined 3D display condition is not satisfied, the present invention is displayed as the 2D symbol instead of the 3D symbol.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, the operation block 102 refers to a touch screen, a touch pad, or the like mounted on a display screen such as an LCD display panel, for example, and a user (or a driver) may use a user interface in the operation block 102. Through operation, various service operations required for driving a vehicle may be provided, for example, operation services for inputting a destination, selecting a driving route, and searching a map of a specific point, etc., and operation signals generated according to a user's operation may be controlled. Provided to block 106.

In addition, the operation block 102 allows the user to select a 3D symbol representation for a particular landmark (eg, select a gas station, golf course, etc.), or select (set) a map display angle and a map scale as a 3D representation condition, or When a user interface for receiving detailed information about a landmark occurs, a control block 106 is generated by selectively generating a corresponding 3D symbol display selection signal, a map display angle selection signal, a map scale selection signal, a detailed information request signal, and the like. ), Such as deliver. Here, as an example, by selecting a reference angle of 45 degrees or more and a reference scale of 1/800 or less, for a landmark when the map display angle is 45 degrees or more and the map scale is 1/800 or less It can be set to display as a 3D symbol (3D model or 3D animation). That is, the driver can select only the landmarks he prefers as the 3D display target, and can arbitrarily set the 3D display conditions (map display angle and map scale factor). Here, the map scale used may be 1/50, 1/100, 1/200, 1/400, 1/800, 1/1600, 1/6400, 1/12800, 1/100000, etc. have.

Passed to block 1064.

In addition, the 3D adaptive selection block 1064 searches for symbol presentation information (ie, landmark information of the 3D presentation object selected or set by the user) previously stored in the additional information storage block 1084 based on the provided landmark detection signal. By checking whether or not the landmark is a 3D display target, and whether or not the current symbol display condition satisfies the preset 3D display condition when the target is a 3D display target, A corresponding 3D symbol presentation signal is generated and delivered to the information extraction block 1066. Of course, if the detected landmark is a 2D display object, the 3D adaptive selection block 1064 will generate a 2D symbol display signal and transmit it to the information extraction block 1066.

As an example, assuming that the reference angle is 45 degrees or more and the reference scale factor is preset to 1/800 or less, if the detected map display angle is 60 degrees and the map scale factor is 1/400, In the 3D adaptation selection block 1064, it is determined that the 3D display condition is satisfied and will generate a 3D symbol display signal including the identifier information of the landmark.

Next, the information extraction block 1066 executes a search for the map information storage block 1082 in the map database 108 based on the current coordinate values of the vehicle provided from the GPS reception block 104 when executing the navigation mode. Map information on the driving route selected by the user (eg, optimal route, shortest route, highway priority route, etc.), and map information data based on the extracted map information are provided to the image processing block 110. When the voice guidance service is needed, the voice guide data is extracted from the voice table (not shown) in the map information storage block 1082 and provided to the voice processing block 112.

Also, the information extraction block 1066 is a 3D symbol data (3D model data or 3D animation data) for the landmark from the additional information storage block 1084 when the 3D symbol presentation signal is transmitted from the 3D adaptive selection block 1066 Extract and transfer the 2D symbol data for the landmark from the additional information storage block 1084 to the image processing block 110 when the 2D symbol presentation signal is transmitted. Provides the functionality of

Further, when the detailed information request signal is input from the operation block 102 in accordance with the present invention, the information extraction block 1066 extracts detailed information about the landmark from the additional information storage block 1084 to display the image processing block ( 110) to provide such a function.

To this end, the map information storage block 1082 in the map database 108 stores map information data and various voice guidance data required for providing a navigation service, and the additional information storage block 1084 stores each land. Stores 2D symbols and / or 3D symbol data corresponding to a mark, detailed information for each landmark, symbol display information (landmark information of a 3D display target selected or set by a user), preset 3D display condition information, and the like. It is. Here, the detailed information for each landmark is detailed description information that is useful for users to know about the landmark, for example, assuming that the landmark is an amusement park, business hours information, age-specific fee information, discount card, etc. Information, play type information, and so on.

Next, the image processing block 110 optionally includes 2D or 3D symbols corresponding to the landmarks through graphic processing of map information data delivered from the information extraction block 1066 when the navigation device is executing the navigation mode. Configure a map information screen (driving route map information screen) or a combined map information screen combined with detailed information in the form of a pop-up menu, and the map information screen or the combined map information screen configured as described above may be a monitor (not shown). For example, an LCD panel).

The voice processing block 112 converts the voice guidance data selectively provided from the information extraction block 1066 into an analog voice signal when the navigation device is executing the navigation mode, and amplifies the voice to a predetermined level and removes noise. And the like, and output a voice signal processed as described above to a speaker (not shown). Here, the speaker may be a speaker of an A / V device or an audio device mounted in a vehicle, or a speaker mounted in the navigation device itself.

Next, a series of processes for selectively displaying (displaying) 2D or 3D symbols corresponding to each landmark detected during execution of the navigation mode using the symbol information display apparatus of the present invention having the above-described configuration will be described. Explain.

When executing the mode (step 202), the landmark detection block 1062 in the control block 106 searches for a landmark that searches for the additional information storage block 1084 based on the location information provided from the GPS reception block 104. When the landmark is generated (steps 204 and 206), if the landmark is detected as a result of the check, a landmark detection signal corresponding to the landmark is generated and provided to the 3D adaptive selection block 1064.

In response, the 3D adaptive selection block 1064 searches for symbol presentation information (ie, landmark information of the 3D presentation object selected or set by the user) previously stored in the additional information storage block 1084 (step 208). It is checked whether the detected landmark is a 2D display target or a preset 3D display target (step 210).

If it is determined in step 210 that the landmark is a 2D display target, the 3D adaptive selection block 1064 generates a 2D symbol display signal and transmits it to the information extraction block 1066, and as a result, extracts the information. Block 1066 extracts the 2D symbol for the landmark from the side information storage block 1084 and transfers it to the image processing block 110 so that the 2D symbol for the landmark is displayed (displayed) on the monitor (step). 216), processing then proceeds to step 220, described below.

On the other hand, as a result of the check in step 210, when the landmark is a 3D display target, the current symbol display condition is searched (step 212), whereby the current symbol display condition satisfies the preset 3D display condition. (Step 214), if the result of the check here does not meet the preset 3D presentation condition, then processing proceeds to step 216, whereby the 2D symbol for the landmark is displayed on the monitor.

If it is determined in step 214 that the predetermined 3D presentation condition is satisfied, the 3D adaptation selection block 1064 generates a corresponding 3D symbol display signal and provides it to the information extraction block 1066. Here, the symbol presentation condition may be, for example, a map display angle and a map scale factor.

In response, the information extraction block 1066 extracts the 3D symbol for the landmark from the side information storage block 1084 and transfers it to the image processing block 110, whereby the 3D symbol (3D) for the landmark is displayed on the monitor. The model or 3D animation) is displayed (displayed) (step 218) and subsequent processing proceeds to step 220.

That is, the user may receive a service for detailed information of the landmark by touching a 2D symbol or a 3D symbol displayed on the monitor, and for this purpose, in step 220, whether or not the user interface is generated Check it. Here, the user interface is generated from the operation block 102 according to the user touch and provided to the information extraction block 1066.

If it is determined in operation 220 that a user interface for a symbol of a specific landmark is generated, the information extraction block 1066 extracts detailed information about the landmark from the additional information storage block 1084. The image is transferred to the image processing block 110, and as a result, detailed information in the form of a pop-up menu is displayed (displayed) on the monitor (step 222). Here, the pop-up menu for the detailed information may be set to be turned off when the user interface (touch) occurs again or to be turned off automatically after a predetermined time elapses.
