Specifically, the CPU, various programs interpreted and executed on the CPU (a basic control program such as an OS, and a program that is activated and specified on the OS). And an internal memory such as a RAM for storing the program and various data. In particular, the driving support program according to Embodiment 1 is substantially installed in the driving support device 50 via an arbitrary recording medium or network, thereby substantially configuring each unit of the control unit 51. Note that the information stored by the RAM of the control unit 51 includes destination information and registered location information. Here, the “destination” is a position set as the final destination of the host vehicle. The “registered place” is a position registered for setting as a destination or a stopover. For example, the registered place information is configured by associating the position (coordinates) of the registered place with an image.

  The control unit 51 includes an image acquisition unit 51a, a character recognition unit 51b, a shooting intention estimation unit 51c, and a driving support unit 51d in terms of functional concept.

  The image acquisition unit 51a is an image acquisition unit that acquires image data captured by an imaging device. Here, the “photographing device” is any device capable of photographing image data, and includes, for example, a digital camera and a mobile phone with a photographing function. The specific acquisition method for the image acquisition unit 51a to acquire image data from the photographing device is arbitrary, for example, wired communication via a communication cable, wireless communication such as Bluetooth, or various recording media, Image data can be acquired.

Further, the map information includes facility information (for example, the name, address, coordinates, and genre of the facility) for specifying the destination.

(processing)
Next, driving support processing executed by the driving support device 50 configured as described above will be described. FIG. 2 is a flowchart of the driving support process (steps are abbreviated as “S” in the description of each process below). First, when the user inputs image data captured by the imaging device to the driving support device 50, this image data is acquired by the image acquisition unit 51a (SA1). Next, the character recognition unit 51b performs character recognition on the image data acquired by the image acquisition unit 51a (SA2). If the character recognition can be performed normally (SA3, Yes), the process proceeds to SA4. If the character recognition cannot be performed normally (SA3, No), a predetermined value is displayed on the display 30. Is displayed (SA7), and the driving support process is terminated. Here, the case where the character recognition could not be performed normally is, for example, a case where the character recognition process could not be completed due to poor image quality of the image data or a case where the character recognition process could be completed. However, this includes the case where no character is included in the character recognition result.

  When the character recognition can be normally performed (SA3, Yes), the shooting intention estimation unit 51c specifies the dot pitch of the image data, and the specified dot pitch is a dot set in advance in the data recording unit 52. It is determined whether or not the pitch is greater than a threshold value (hereinafter referred to as “reference dot pitch”) (SA4). That is, when the subject of the image data is a printed matter, since the printed matter is printed with dots having a constant pitch, it is determined based on the constant pitch whether the subject is a printed matter. Here, the pitch of the average CCD element used in the imaging device that captured the image data is the reference dot pitch. If the dot pitch of the image data is larger than the reference dot pitch, the subject of the image data is Assume that the image data is a printed material, and if the dot pitch of the image data is equal to or less than the reference dot pitch, the subject of the image data is not a printed material. However, a dot pitch other than the CCD element pitch may be used as the reference dot pitch. Depending on the setting of the reference dot pitch, if the dot pitch of the image data is the same as the reference dot pitch, or if the dot pitch of the image data is less than or equal to the reference dot pitch, the subject of the image data is a printed matter. You may make it determine with there.

  When it is determined that the dot pitch of the image data is larger than the reference dot pitch (SA4, Yes), the shooting intention estimation unit 51c captures the printed matter and inputs the image data to the driving support device 50. This is because the spot information printed on the printed material is used for assistance in the driving support device 50, and the intention to capture the image data is the intention to set the spot information included in the subject of the image data as the destination. Based on the estimated character recognition result of SA2, the destination is set (SA5). For example, the name, address, genre, etc. of the facility are extracted from the character information acquired by the character recognition of SA2, based on the well-known language analysis logic, and the extracted name, address, and The coordinates of the facility corresponding to the genre and the like are acquired from the map information DB 52a, and the destination is set using the acquired coordinates. By setting the destination in this way, the user's own vehicle detected by the current position detection processing unit 10 when the user gives an instruction by a predetermined method or automatically after the processing of SA5 is performed. A route from the current position to the destination is searched by a known route search logic, and the searched route is guided to the user via the display 30 and the speaker 40.

  On the other hand, when it is determined that the dot pitch of the image data is not larger than the reference dot pitch (SA4, No), the shooting intention estimation unit 51c sets the shooting intention of the image data to the point information included in the subject of the image data. It is presumed that it is not intended to be set to the ground but intended to be set to the registered place, and based on the character recognition result of SA2, the registered place is set and the icon is displayed (SA6). For example, when the name, address, genre, etc. of a facility can be extracted from the character information acquired by the character recognition of SA2 by the same method as SA5, SA5 is based on the name, address, genre, etc. The coordinates acquired by the same method as above are registered in the RAM of the control unit 51 as the coordinates of the registration place. Alternatively, when the name, address, genre, etc. of the facility cannot be extracted, and the coordinates are added to the image data, the coordinates are registered in the RAM of the control unit 51 as the coordinates of the registration location, and the image If no coordinates are added to the data, the coordinates of the current position detected by the current position detection processing unit 10 are registered in the RAM of the control unit 51 as the coordinates of the registration location. At this time, the image data is registered in the RAM in association with the coordinates. By setting the registered location in this way, the user can instruct the registered location from the RAM of the control unit 51 by giving an instruction by a predetermined method at an arbitrary timing thereafter, and on the map information in the map information DB 52a. The image data of the registered place is read from the RAM of the control unit 51 and displayed on the display 30. Then, when the user sets the displayed registered location as a destination by a predetermined operation, a route from the current position of the host vehicle to the destination is searched by a known route search logic, and the searched route is The user is guided through the display 30 and the speaker 40. The display of the icon means, for example, that an icon having a predetermined shape is superimposed on the coordinates of the registered place specified as described above in the map information read from the map information DB 52a and displayed on the display 30. Although the shape of the icon is arbitrary, it is preferable that the icon has a shape that allows the user to easily grasp that the address acquired from the image data is displayed. By displaying the icon in this way, the user can easily grasp the address included in the subject of the image data by associating it with the map information, and if necessary, by giving an instruction by a predetermined method, the icon can be displayed. By setting the displayed address as a destination, a route from the current position of the host vehicle to the destination is searched by a known route search logic, and the searched route is displayed via the display 30 and the speaker 40. Be guided to.

(effect)
As described above, according to the first embodiment, the shooting intention of the image data is estimated, and driving assistance using the image data is performed based on the estimated shooting intention. It becomes unnecessary to give an instruction, and convenience in performing driving support using images can be improved.

  In addition, since it is estimated that the shooting intention of the image data is the intention to set the point information included in the subject of the image data as the destination, the point information is automatically set as the destination, etc. Convenience in performing destination setting using can be enhanced.

  Further, when it is determined that the subject is a printed matter, it is estimated that the shooting intention of the image data is the intention to set the point information included in the subject as the destination, and the point information included in the subject is Since it is set to the ground, the destination can be automatically set by inputting the image data with the printed matter as the subject, and the convenience in setting the destination using the printed matter can be enhanced.

  Further, since it is determined whether or not the subject is a printed matter based on the dot pitch of the image data, it is difficult to determine whether or not the subject is a printed matter based on information included in the subject. However, it can be determined whether or not the subject is a printed matter.

[Embodiment 2]
Next, a second embodiment will be described. In the second embodiment, when it is determined that the image data includes unique point information, it is estimated that the shooting intention of the image data is an intention to set the unique point information as a destination. This is a form of providing support. The configurations of the second embodiment and the subsequent embodiments are substantially the same as the configurations of the first embodiment unless otherwise specified, and this configuration is substantially the same as the configuration of the first embodiment. The same reference numerals and / or names as those used in Embodiment 1 are attached as necessary, and the description thereof is omitted.

(Constitution)
First, the configuration of the driving support system according to the second embodiment will be described. The driving support system 1 can be configured in substantially the same manner as the driving support system 1 according to the first embodiment, but the function of the shooting intention estimation unit 51c is different and a template is stored in the data recording unit 52. It is different.

  Here, the template specifies the configuration of the stylized image data in order to estimate the shooting intention of the image data based on the configuration of the image data. In the second embodiment, as the configuration of the stylized image data, there are two types: a configuration in the case where the image data includes unique point information, and a configuration in which the image data includes a plurality of point information. It is assumed that two types of templates are set: a template for specifying the former configuration (hereinafter referred to as “unique template”) and a template for specifying the latter configuration (hereinafter referred to as “multiple templates”).

  FIG. 3 is a diagram illustrating a single template 60 registered in the driving support system 1. This unique template 60 includes a store name area 61, a store introduction text area 62, an address and telephone area 63, a first in-store photo area 64, and a second in-store photo area 65 in the size and arrangement shown in the drawing. It is configured to include. That is, in the second embodiment, it is assumed that the introduction information of the shop is included as the only point information, and the image data having a configuration that matches the template 60 is an image including the only point information. It is data, and the information displayed in the address and telephone area 63 is specified as the information indicating the address and telephone.

  FIG. 4 is a diagram illustrating a plurality of templates 70 registered in the driving support system 1. The plurality of templates 70 include a first display area 71 to a fourth display area 74. In each of the first display area 71 to the fourth display area 74, a store name area 75, a store introduction text area 76, an address. The telephone area 77 is configured to include the illustrated size and arrangement. That is, in the second embodiment, it is assumed that introduction information of a plurality of shops is included as a plurality of point information, and image data having a configuration that matches the plurality of templates 70 includes a plurality of point information. The image data that is included, and the information displayed in the address and telephone area 77 is specified as the information indicating the address and telephone of each store.

  The unique template 60 and the plurality of templates 70 are arbitrarily created by the user and stored in the data recording unit 52 by the user in a predetermined method at an arbitrary timing prior to a driving support process described later. For example, the example shown in FIGS. 3 and 4 is an example of a unique template 60 and a plurality of templates 70 that reflect a typical configuration of an introductory article of a store published in a magazine, and the magazine is photographed with a photographing device. This is an example stored by the user when it is assumed that image data is acquired. Therefore, when it is assumed that image data of another configuration is acquired, the user creates a template that matches the other configuration and stores it in the data recording unit 52. As a specific method for creating this template, for example, a known drawing process can be applied.

(processing)
Next, driving support processing executed by the driving support device 50 configured as described above will be described. FIG. 5 is a flowchart of the driving support process. However, SB1 to SB3 and SB7 are the same as SA1 to SA3 and SA7 in FIG.

  When the character recognition can be performed normally (SB3, Yes), the shooting intention estimation unit 51c specifies the area where the character is displayed in the image data. Then, the photographing intention estimation unit 51 c reads the unique template 60 and the plurality of templates 70 from the data recording unit 52, and the configuration of the area where the characters are displayed in the image data is identified by the unique template 60 and the plurality of templates 70. It is determined which of the configurations specified by (SB4). That is, the image data acquired in SB1 includes the store name area 61, the store introduction text area 62, the address and telephone area 63, the first in-store photo area 64, and the second in-store photo area 65 in FIG. If it is configured to include the size and arrangement shown in the only template 60, it is determined that the configuration of the image data matches the configuration specified by the template 60 only. Alternatively, the image data acquired in SB1 includes the first display area 71 to the fourth display area 74. In each of the first display area 71 to the fourth display area 74, the store name area 75 and the store introduction are included. When each of the body area 76, the address, and the telephone area 77 is configured to include the size and arrangement shown in the plurality of templates 70 in FIG. 4, the configuration of the image data is specified by the plurality of templates 70. It is determined that it matches. Here, not only when the configuration of the image data acquired in SB1 completely matches the configuration specified by the template 60 or the plurality of templates 70, but the configuration specified by the template 60 or the plurality of templates 70 is used as a reference. In the case where it is included in a predetermined allowable range set in advance, it may be determined that it matches only the configuration specified by the template 60 or the configuration specified by the plurality of templates 70. For example, the image data acquired in SB1 includes the first display area 71 to the fourth display area 74, and only the address and telephone area 77 are included in each of the first display area 71 to the fourth display area 74. If included, even if the address and telephone area 77 are included in a size and arrangement different from those shown in the plurality of templates 70 in FIG. It may be determined that the configuration specified by the template 70 is matched.

  When it is determined that the image matches only the configuration specified by the template 60 (SB4, Yes), the shooting intention estimation unit 51c sets the shooting intention of the image data to the point information included in the subject of the image data as the destination. Estimating that the intention is to be set, the destination is set based on the character recognition result of SB2 (SB5). For example, among the character information acquired by the character recognition of SB2, only the address in the template 60 and the character information acquired from the range corresponding to the telephone area 63 is used to determine the address based on the well-known language analysis logic. Extraction is performed, and a destination is set based on the extracted address.

  On the other hand, when it is determined that it matches the configuration specified by the plurality of templates 70 (SB4, No), the shooting intention estimation unit 51c sets the shooting intention of the image data to the point information included in the subject of the image data. It is presumed that it is not intended to be set to the ground but intended to be set as the registered place, and based on the character recognition result of SB2, registration place setting and icon display are performed (SB6). For example, in the character information acquired by the character recognition of SB2, the character information acquired from the range corresponding to the address and the telephone area 77 in each of the first display area 71 to the fourth display area 74 of the plurality of templates 70. The address is extracted based on the well-known language analysis logic, and the registration location is set based on the extracted address in the same manner as the process of SA6 in FIG. Alternatively, similar to the processing of SA6 in FIG. 2, the registration location is set based on the coordinates added to the image data and the coordinates of the current position detected by the current position detection processing unit 10, or icon display is performed. Furthermore, when the user sets a registered destination as the destination, the route to the destination can be searched.

(effect)
As described above, according to the second embodiment, the shooting intention of the image data is estimated, and driving assistance using the image data is performed based on the estimated shooting intention. It becomes unnecessary to give an instruction, and convenience in performing driving support using images can be improved.

  In addition, since it is estimated that the shooting intention of the image data is the intention to set the point information included in the subject of the image data as the destination, the point information is automatically set as the destination, etc. Convenience in performing destination setting using can be enhanced.

  In addition, when it is determined that the image data includes unique point information, the intention to capture the image data is estimated to be the intention to set the unique point information as a destination, and the unique point information is Since the destination is set, the destination can be automatically set by inputting image data including only point information, and the convenience in setting the destination using the image data is improved. be able to.

[Modifications to Embodiment]
Although the embodiments of the present invention have been described above, the specific configuration and means of the present invention can be arbitrarily modified and improved within the scope of the technical idea of each invention described in the claims. Can do. Hereinafter, such a modification will be described.

(About problems to be solved and effects of the invention)
First, the problems to be solved by the invention and the effects of the invention are not limited to the above contents, and may vary depending on the implementation environment and details of the configuration of the invention. May be solved, or only some of the effects described above may be achieved.

(Reciprocal relationship between the embodiments)
Between the first and second embodiments, part of the configuration and processing may be interchanged, or one configuration and processing may be applied to the other. For example, the process of estimating the user's shooting intention using only the template 60 or the plurality of templates 70 in the second embodiment may be added to the first embodiment. Specifically, when it is determined that the subject is a printed matter in the determination based on the dot pitch, the determination using only the template 60 or the plurality of templates 70 is performed, and the configuration of the image data is specified by the template 60 only. If it matches the configuration, the destination is set based on the result of character recognition from the image data. If the image data configuration does not match the configuration specified by the template 60, character recognition is performed from the image data. Based on the result, icon display and registration location setting may be performed.

(About character recognition timing)
In each of the above-described embodiments, the determination of image data capture intention is performed after character recognition is performed. However, character recognition may be performed after determination of image data capture intention is performed. For example, as a modification of the processing of FIG. 2, it is determined whether or not the dot pitch is greater than the reference dot pitch after image acquisition. If the dot pitch is greater than the reference dot pitch, character recognition is performed and character recognition is performed. If it is possible, the SA5 process may be performed based on the character recognition result, and if the character recognition is not possible, an SA7 error display may be performed. If the dot pitch is not larger than the reference dot pitch, character recognition is performed. If character recognition is possible, the process of SA5 is performed based on the character recognition result, and character recognition is not possible. In some cases, if coordinates are added to the image data, the process of SA6 is performed based on the coordinates, and if no coordinates are added to the image data, an error display of SA7 is performed. Good.

(About driving support according to the user's intention to shoot)
In the first and second embodiments, when it is estimated that the intention of photographing the image data is not intended to set the spot information included in the subject of the image data as the destination, the registered location setting and icon display are performed. However, any other driving assistance may be performed. For example, an address is extracted from character information obtained by character recognition of image data based on a well-known language analysis logic, and when there are a plurality of the extracted addresses, the plurality of addresses are listed. You may display on the display 30 in a format.
