Method, binarization method, pattern matching method, and the like, may be executed alone or in combination.
[0023]
On the other hand, the current position information of the vehicle is calculated by the position information obtaining means 204 using information of the GPS antenna 101 and the vehicle speed sensor 105 shown in FIG. The map data is stored in the storage unit 209, and as a storage medium of the storage unit 209, a CD-ROM, a DVD-ROM, or the like has already been widely used for this purpose. In addition, a configuration may be adopted in which necessary data is updated as needed via a network in a rewritable storage medium such as a hard disk or a RAM. The storage medium is not particularly limited as long as the storage medium can store map information.
[0024]
The route search means 205 uses the current position information, the map data, and the destination information input by the user 208 via the input operation means 210 or the voice input / output means 207 to obtain an optimal route from the current position to the destination. To explore. Various algorithms have been proposed for the optimal route search algorithm, including those that have been put into practical use and those that are under study, but are not particularly limited.
[0025]
The guidance data creation unit 206 creates guidance data that represents the optimal route searched by the route search unit 205 using the feature information of the route change point extracted by the image analysis unit 202 and the map data. The guidance data created by the guidance data creation unit 206 effectively uses image information, text information, and voice information, and is output to the user 208 via the display unit 203 and the voice input / output unit 207.
[0026]
The voice input / output unit 207 has a microphone and a speaker, and is used for voice input from the user 208 and output of guidance data from the guidance system to the user 208. The display unit 203 uses a CRT (Cathode Ray Tube), a liquid crystal, a PDP (Plasma Display Panel), an organic EL (Electro Luminescence), or the like, and displays guidance data to the user 208.
[0027]
Next, a guidance processing operation performed in the guidance system according to the present embodiment will be described with reference to a flowchart shown in FIG.
[0028]
First, the user 208 using the guidance system starts the guidance system (step S301). The user 208 sets an arbitrary destination in the guidance system via the voice input / output unit 207 or the input operation unit 210 (step S302). The guidance system analyzes the information of the GPS antenna 101 and the vehicle speed sensor 105 shown in FIG. 1 by the position information acquisition means 204, and acquires the current position information of the automobile 113 (step S303).
[0029]
If the current position information is obtained, the route search means 205 searches for an optimal route from the current position to the destination with reference to the destination and the map data in the storage means 209 (step S304). The searched optimum route is presented to the user 208 via the display means 203 and the voice input / output means 207. At this time, a plurality of searched route candidates are output according to conditions, and the user 208 The user 208 may be selected, or one optimal route determined by the guidance system may be presented to the user 208.
[0030]
When the optimum route from the current position to the destination is determined in this way, the user 208 confirms it and starts running the automobile 113 (step S305). During traveling, the guidance system updates the current position information by the position information acquisition unit 204 again at a certain timing, for example, when a set condition such as elapse of a certain time or running a certain distance is satisfied (step S306).
[0031]
Thereby, the guidance system can always grasp the latest current position of the automobile 113.
[0032]
Then, when the latest current position is grasped, the current position information and the map information are updated as to whether or not the current position is around the destination (step S307) and whether or not it is near the course change point (step S308). The determination is made with reference to the determined route information.
[0033]
Here, if the current position is around the set destination, the fact is notified to the user 208, and the route guidance processing ends (step S315).
[0034]
If the current position is neither near the destination nor near the course change point, the user 208 continues to run the car 113 (step S305) and updates the current position information, and determines whether the current position is the destination and the course change point. (Steps S306 to S308) are repeated.
[0035]
Further, when the current position approaches the course change point, the guidance system takes an image of the vicinity of the course change point by the photographing means 201 (step S309). The image photographed by the photographing unit 201 is input to the image analyzing unit 202, and the feature information of the course change point is extracted using the above-described image analysis algorithm (step S310).
[0036]
Here, first, an obstacle on the road at the course change point is detected, and it is determined whether or not the course change is possible (step S311). For example, when the road at the course change point is cut off or under construction, the fact is notified to the user 208 (steps S316 and S317), and another route not using the corresponding course change point is notified. A re-search is performed (step S304).
[0037]
Here, it is assumed that an image as shown in FIG. 4 is taken around the course change point. The guidance system sets the route that changes the route to the left at this intersection as the optimal route. At this time, the image analysis unit 202 obtains information that the building 401, the factory 402, and the signboard 403 under construction are adjacent to this intersection. In this way, the guidance system recognizes that the road to be changed is under construction and the passage is impossible, and immediately searches for another route again, as shown in FIG. The construction mark 501 is displayed on the map data, and the voice input / output unit 207 notifies the user 208 of guidance information such as "the left turn is under construction" and "the course will be changed". If there is no obstacle on the road or if it is determined that traffic is possible even if there is an obstacle, the obstacle and other features such as signs, buildings, installations, other automobiles, and motorcycles The guide data is created for the user 208 so that the user, the bicycle, the person, and the like can be used as a mark of the course change point (step S313), and is presented to the user 208 (step S314).
[0038]
Specifically, it is assumed that an image as shown in FIG. 6 is taken around the course change point. The guidance system sets the route that changes the route to the left at this intersection as the optimal route. At this time, the image analysis means 202 informs the intersection that a building 601 with a red roof, a convenience store (convenience store) 602, a signboard 603, and a gas station 604 are adjacent to each other, and a blue car 605 is running in front of the intersection. can get. Further, information is also obtained that the course change direction is between the building 601 with the red roof and the convenience store 602, and that the blue car 605 traveling ahead is making a similar course change.
[0039]
If such information is obtained, the guidance system, as shown in FIG. 7, the blue car 701 marked as "follow" the map data on the display means 203, the building 702 with the red roof, the convenience store 703, the signboard 704. And the gas station 705 is displayed so as to stand out more than other information. The voice input / output means 207 presents guidance information to the user 208 such as "turn left", "the road between the building with the red roof and the convenience store", and "the same route as the blue car ahead". It becomes possible.
[0040]
The user 208 knows such detailed information of the actual site in advance and grasps the specific situation of the course change point in advance, so that when the course is changed, the user can refer to the information to make a smoother response. Can be expected (step S314). When the course change is completed, the user 208 drives the car 113 again along the road (step S305).
[0041]
By repeating the processing from step S304 to step S314 as described above, the user 208 can efficiently reach the set destination.
[0042]
The voice guidance at the course change point described above and the display guidance shown in FIGS. 5 and 7 are merely examples, and it goes without saying that the present invention is not limited to this.
[0043]
In the present embodiment, the photographing means 201 performs photographing only when the car 113 approaches the course change point, but may continuously photograph while the guidance system is running, and may store it as a driving record. .
[0044]

Even if the holding method is changed, the lens can always be directed forward in a direction in which the photographing can be performed, and image information in the traveling direction of the user 208 is acquired.
[0053]
The image information obtained by the photographing unit 201 is analyzed by the image analyzing unit 202. Here, characteristic information of a course change point is extracted by analyzing color information, luminance information, frequency information, pattern regularity information, and the like of the image. The characteristic object here refers to, for example, a road, a traffic sign, a signboard, a building, an installed object, another automobile, a motorcycle, a bicycle, a person, and the like. Furthermore, the various information in the image and the image analysis processing method used in the image analysis for obtaining the characteristic object information on the course are not limited to the above-mentioned ones. Method, binarization method, pattern matching method, etc., may be executed alone or in combination.
[0054]
On the other hand, the current position information of the user 208 is calculated by the position information acquisition unit 204 using information from the GPS antenna 802. The map data is stored in the storage unit 209, and as a storage medium of the storage unit 209, a CD-ROM, a DVD-ROM, or the like has already been widely used for this purpose. In addition, a configuration may be adopted in which necessary data is updated as needed via a network in a rewritable storage medium such as a hard disk or a RAM, and any storage medium that can store map information is not particularly limited. Absent.
[0055]
The route searching means 205 uses the current position information, the map data, and the destination information input by the user 208 through the input operation means 210 or the voice input / output means 207 to find an optimal route from the current position to the destination.

There are various algorithms for searching for the optimum route, including those that have been put into practical use and those that are under study, but are not particularly limited, and any method may be used.
[0056]
The guidance data creation unit 206 creates guidance data that represents the optimal route searched by the route search unit 205 using the feature information of the route change point extracted by the image analysis unit 202 and the map data. The guidance data created by the guidance data creation unit 206 effectively uses image information, text information, and voice information, and is output to the user 208 via the display unit 203 and the voice input / output unit 207. The voice input / output unit 207 has a microphone and a speaker, and is used for voice input from the user 208 and output of guidance data from the guidance system to the user 208.
[0057]
The display unit 203 uses a CRT (Cathode Ray Tube), a liquid crystal, a PDP (Plasma Display Panel), an organic EL (Electro Luminescence), or the like, and displays guidance data to the user 208.
[0058]
Next, a guidance processing operation executed in the guidance system according to the present embodiment will be described using a flowchart shown in FIG.
[0059]
First, the user 208 using the guidance system starts the guidance system (step S901). The user 208 sets an arbitrary destination in the guidance system via the voice input / output unit 207 or the input operation unit 210 (step S902). The guidance system analyzes the information from the GPS antenna 802 shown in FIG. 8 by the position information acquisition unit 204 and acquires the current position information of the user 208 (step S903). If the current position information is acquired, the route search means 205 searches for an optimal route from the current position to the destination with reference to the destination and the map data in the storage means 209 (step S904).
[0060]
The searched optimum route is presented to the user 208 via the display unit 203 and the voice input / output unit 207. At this time, a plurality of searched route candidates are output according to conditions, and the user is allowed to select from them. Alternatively, one of the optimal routes determined by the guidance system may be presented.
[0061]
When the optimum route from the current position to the destination is determined in this way, the user 208 confirms it and starts moving (step S905). During movement, the guidance system updates the current position information by the position information acquisition means 204 again at a certain timing, for example, when a set condition such as elapse of a certain time or movement of a certain distance is satisfied (step S906).
[0062]
Thereby, the guidance system can always grasp the latest current position of the user 208. Then, when the latest current position is grasped, the current position information and the map information are updated as to whether the current position is around the destination (step S907) and whether it is around the course change point (step S908). The determination is made with reference to the determined route information.
[0063]
Here, if the current position is around the set destination, the user 208 is notified to that effect and the guidance processing operation ends (step S915). If the current position is not near the destination or the route change point, the user 208 continues to move (step S905), updates the current position information, and determines whether the current position is the destination and the route change point. (Steps S906 to S908) are repeated. Further, when the current position approaches the course change point, the guidance system takes an image of the vicinity of the course change point by the photographing means 201 (step S909). The image photographed by the photographing unit 201 is input to the image analyzing unit 202, and the feature information of the course change point is extracted using the above-described image analysis algorithm (step S910).
[0064]
Here, first, an obstacle on the road at the course change point is detected, and it is determined whether or not the course change is possible (step S911). For example, when the road at the course change point is cut off or under construction, the fact is notified to the user 208 (steps S916 and S917), and the re-routing of another route not using the corresponding course change point is performed. A search is performed (step S904).
[0065]
Here, it is assumed that an image as shown in FIG. 4 is taken around the course change point. The guidance system sets the route that changes the route to the left at this intersection as the optimal route. At this time, the image analysis unit 202 obtains information that the building 401, the factory 402, and the signboard 403 under construction are adjacent to this intersection. In this way, the guidance system recognizes that the road to be changed is under construction and the passage is impossible, and immediately searches for another route again, as shown in FIG. The construction mark 501 is displayed on the map data, and the voice input / output unit 207 notifies the user 208 of guidance information such as "the left turn is under construction" and "the course will be changed". In addition, if it is determined that there is no obstacle on the road or that it is possible to pass even if there is an obstacle, obstacles and other features such as signs, buildings, installations, other automobiles, motorcycles, Guidance data for the user 208 is created so that a bicycle, a person, and the like become a mark of a course change point (step S913), and is presented to the user 208 (step S914).
[0066]
Specifically, it is assumed that an image as shown in FIG. 6 is taken around the course change point. The guidance system sets the route that changes the route to the left at this intersection as the optimal route. At this time, the image analysis means 202 obtains information that a building 601 with a red roof, a convenience store 602, a signboard 603, and a gas station 604 are adjacent to this intersection, and a blue car 605 is running ahead. Further, information is also obtained that the course change direction is between the building 601 with the red roof and the convenience store 602, and that the blue car 605 traveling ahead is making a similar course change.
[0067]
If such information is obtained, the guidance system, as shown in FIG. 7, the blue car 701 marked as "following" the map data on the display means 203, the building 702 with the red roof, the convenience store 703, the signboard 704, and The gas station 705 is displayed so as to be more prominent than other information, and the voice input / output means 207 “turn left”, “the road between the building with the red roof and the convenience store”, and “blue ahead” It is possible to present to the user 208 guidance information such as "It is the same path as a car."
[0068]
The user 208 knows such detailed information of the actual site in advance and grasps the specific situation of the course change point in advance, so that when the course is changed, the user can refer to the information to make a smoother response. Can be expected (step S914). When the course change is completed, the user 208 moves again along the road (step S905).
[0069]
