(Embodiment 1)
In the present embodiment, a map output device that automatically outputs a map including a departure point and a current point will be described. In addition, the map output apparatus in this Embodiment is utilized for the object for walks and a water moving body, for example.

  In the present embodiment, a map output device that clearly indicates the current location and the departure location will be described.

  In the present embodiment, a map output device that outputs distance information related to the distance from the departure point to the current position will be described. The distance information here is usually a straight line distance.

  FIG. 1 is a block diagram of a map output device 1 in the present embodiment. The map output device 1 includes a storage unit 11, a processing unit 12, and an output unit 13.

  The map output device 1 may be held by a person or may be installed on a moving body. The moving body is preferably a water moving body. A surface moving body is a moving body that travels on the water such as the sea, a lake, or a pond. Examples of the water moving body include a water jet, a marine jet, a water motorcycle, a yacht, a ship, and a jet ski. The mobile body is preferably a mobile body that needs to return to the starting point, such as a water mobile body.

  The storage unit 11 includes a map information storage unit 111 and a departure position information storage unit 112.

  The processing unit 12 includes a departure position information acquisition unit 121, a current position information acquisition unit 122, a map information acquisition unit 123, and a distance information acquisition unit 124.

    The map information acquisition unit 123 includes a scale determination unit 1231, a map information acquisition unit 1232, and a determination unit 1233.

  The output unit 13 includes a map information output unit 131 and a distance information output unit 132.

  The storage unit 11 can store various types of information. The various types of information are, for example, map information and departure position information described later.

  The map information storage unit 111 can store map information. Map information is information constituting a map. The map information includes, for example, a map image (may be referred to as map symbol information), one or more objects displayed on the map, and the type of the object. The map information is in KIWI format, for example. However, the format, content, etc. of the map information are not questioned. The map information includes, for example, term information including map symbol information indicating a map symbol and position information indicating a term and a position of the term on the map. The map symbol information is, for example, a bitmap or vector data constituting the map. The term has an object (character string) written on a map. The position information is information having latitude and longitude on a map, X and Y coordinate values on a two-dimensional plane, and the like. The map information preferably includes map symbol information and term information for each scale. The object refers to a place name, a building, a scenic spot, a place name, a park, a mountain, a sea name, a territorial sea name, a lake name, a pond name, a trench name, or the like displayed on the map.

  In addition, maps include, for example, topographic maps, ocean maps, terrain maps, geological maps, land use maps, residential maps, route maps, road maps, guide maps, aerial photographs and satellite photographs that can grasp terrain and roads, etc. The ones with symbols or letters written on them. The map may be not only a land-based map, but also a map of the sea, a lake, or the like, an aerial map, or a map of a building. In addition, the map here is a map where the path through which the moving body passes is not determined, a map where the path through which the moving body passes cannot be specified, a map where the area where the moving body can pass is wider than the threshold, and an area where the moving body can pass However, it is preferable that the map is not a road but an area wider than a threshold.

  The departure position information storage unit 112 can store departure position information. The departure position information is information indicating the departure position. The departure position information usually includes latitude and longitude information. However, as long as the departure position information can identify the departure position, the form, structure, etc. are not limited.

  The processing unit 12 performs various processes. The various processes include, for example, a departure position information acquisition process, a current position information acquisition process, a map information acquisition process, a distance information acquisition process, and the like which will be described later.

  The departure position information acquisition unit 121 performs a departure position information acquisition process. The departure position information acquisition process is a process of acquiring departure position information which is position information indicating a departure point. The departure position information acquisition unit 121 includes, for example, a GPS receiver, and the GPS receiver acquires current position information at the time of departure. However, the method by which the departure position information acquisition unit 121 acquires position information does not matter. The departure position information acquisition unit 121 may acquire position information using radio waves from three or more mobile phone base stations, for example. Note that the current position information acquired by the departure position information acquisition unit 121 is departure position information. Moreover, the trigger which the departure position information acquisition part 121 acquires departure position information does not ask | require. For example, the departure position information acquisition unit 121 may acquire departure position information, which is current position information, when the engine of the moving body on which the map output device 1 is mounted is turned on. In addition, the departure position information acquisition unit 121 may acquire departure position information that is current position information, for example, in accordance with a user instruction. Furthermore, the departure position information acquisition unit 121 may acquire the departure position information by using the mobile terminal on which the map output device 1 is mounted as a trigger.

  The departure position information acquisition unit 121 normally accumulates the acquired departure position information in the departure position information storage unit 112.

  The current position information acquisition unit 122 continuously acquires current position information, which is position information indicating the current location. The current position information acquisition unit 122 includes, for example, a GPS receiver, and the GPS receiver acquires current position information at the time of departure. Note that the operation in which the departure position information acquisition unit 121 acquires position information and the operation in which the current position information acquisition unit 122 acquires position information are usually the same.

  Here, continuously acquiring the current position information means acquiring the current position information at least twice. The current position information acquisition unit 122 may acquire the current position information periodically or may acquire the current position information irregularly.

  Note that the method of acquiring the position information by the current position information acquisition unit 122 is not limited as in the departure position information acquisition unit 121.

  When the departure point and the current point indicated by the latest current position information acquired by the current position information acquisition unit 122 are no longer in a predetermined positional relationship, the map information acquisition unit 123 departs from the departure point and the latest current position information. Map information including the current location indicated by is newly acquired.

  When the departure point and the current point indicated by the latest current position information are no longer in a predetermined positional relationship, the map information acquisition unit 123 newly adds map information on a map with a scale different from the scale of the map being output. It is preferable to obtain the above.

  Here, the predetermined positional relationship is usually a relationship regarding the distance between the departure point and the current point. In addition, the predetermined positional relationship is usually that the distance between the departure point and the current point is so close that the predetermined relationship is satisfied. Further, the predetermined positional relationship is, for example, that both the starting point and the current point are so close that they are included in the output map. Also, the predetermined positional relationship is, for example, when the map is output so that the current point is the center of the map, the more the departure point exists on the map, the more the departure point and the current point are. The distance is close. The predetermined positional relationship is, for example, when the map is output so that the departure point is the center of the map, the more the current point exists on the map, the more the departure point and the current point are. The distance is close.

  That is, the map information acquisition unit 123 normally always acquires map information including the departure point indicated by the departure position information and the current point indicated by the current position information.

  The map information acquisition unit 123 determines that the departure point or the current point indicated by the latest current position information acquired by the current position information acquisition unit 122 is not included in the map information output by the map information output unit 131. It is preferable to newly acquire map information including the current location indicated by the latest current position information.

  The map information here is normally stored in the map information storage unit 111. However, the map information acquisition unit 123 may receive map information from a server device (not shown). When the map information acquisition unit 123 receives map information from a server device (not shown), the map information acquisition unit 123 normally requests map information to be output to the server device, and receives map information corresponding to the request from the server device. To do. Since the technique for receiving the requested map information from the server device is a known technique, detailed description thereof is omitted. Further, the map information requesting method, the request command configuration, etc. are not limited.

  In addition, the map information acquisition part 123 acquires map information normally by the scale determination means 1231, the map information acquisition means 1232, and the judgment means 1233. However, the map information acquisition unit 123 may acquire the map information by another method that does not depend on the scale determination unit 1231, the map information acquisition unit 1232, and the determination unit 1233. For example, when one piece of map information is stored in the map information storage unit 111, the map information acquisition unit 123 sets the area including the departure point indicated by the departure position information and the current point indicated by the current position information. Cut out from one piece of map information, the cut out map information may be enlarged or reduced in accordance with the size of the display, and output map information may be acquired.

  The scale determining means 1231 constituting the map information acquisition unit 123 determines the scale of the map including the departure point indicated by the departure position information and the current point indicated by the current position information. The process for determining the scale may be a process for acquiring a map ID corresponding to the scale, a process for acquiring information indicating the scale, or the like.

  In addition, when position information of two points (departure point and current point) is given, processing for determining map information of a map including the two points and processing for determining a scale of a map including the two points are known techniques. Therefore, detailed description is omitted.

  When the scale determining means 1231 determines that the determining means 1233 is not included, it is preferable to determine the scale of newly acquired map information. However, the scale determining means 1231 may determine the scale of the map information every time the current position information is acquired. In addition, the timing which the scale determination means 1231 performs a scale determination process does not ask | require.

  The map information acquisition unit 1232 is map information corresponding to the scale determined by the scale determination unit 1231 and acquires map information including the departure point and the current point. The processing of the map information acquisition unit 1232 is a known technique.

  The determination unit 1233 determines whether or not the departure point and the current point indicated by the latest current position information acquired by the current position information acquisition unit 122 have a predetermined positional relationship.

  For example, the determination unit 1233 determines whether or not the current location indicated by the latest current position information acquired by the current position information acquisition unit 122 is included in the map information output by the map information output unit 131.

  For example, the determination unit 1233 may determine whether or not the departure point is included in the map information output by the map information output unit 131.

  The determination unit 1233 also determines, for example, whether or not the departure point and the current location indicated by the latest current location information acquired by the current location information acquisition unit 122 are included in the map information output by the map information output unit 131. You may do it.

  The distance information acquisition unit 124 uses the departure position information and the current position information acquired by the current position information acquisition unit 122 to acquire distance information related to the distance from the departure point to the current point. The distance information is preferably a linear distance. However, the distance information is the distance of the route passed from the departure point, and may be the distance to the current point.

  The output unit 13 outputs various types of information. The various information includes, for example, map information, distance information, a departure point mark that is a mark indicating the departure point, a current point mark that is a mark indicating the current point, and the like. Note that the departure point mark and the current point mark are usually output on a map. The mark is usually a mark or a design.

  The output unit 13 may output a movement trajectory of a moving body (not shown) on which the map output device 1 is mounted. That is, the output unit 13 includes two or more positions indicated by two or more current position information that the current position information acquisition unit 122 continuously acquires from the position indicated by the departure position information acquired by the departure position information acquisition unit 121. A trajectory constituted by the transitions of may be output. Note that the output unit 13 normally outputs a trajectory using a line. However, the output unit 13 may output the locus using two or more points.

  The output here is usually a display on a display, but projection using a projector, printing with a printer, sound output, transmission to an external device, accumulation in a recording medium, other processing devices, It is a concept that includes the delivery of processing results to other programs.

  The map information output unit 131 outputs a map using the map information acquired by the map information acquisition unit 123. Note that the output of the map using the map information may be referred to as the output of the map information.

  The map information output unit 131 outputs a map using the new map information acquired by the map information acquisition unit 123.

  Even when updating the output of the map, the map information output unit 131 preferably outputs the current location indicated by the current location information continuously acquired by the current location information acquisition unit 122 in a manner that clearly indicates on the map. It is. Note that the map information output unit 131 normally uses the current location mark to clearly indicate the current location. The map information output unit 131 holds the current location mark in advance. There is no limitation on the shape, data structure, contents, etc. of the current location mark.

  Even when the map information output unit 131 updates the output of the map, it is preferable to output the departure point in such a manner that the departure point is clearly indicated on the map. Note that the map information output unit 131 normally uses a departure point mark to clearly indicate the departure point. The map information output unit 131 holds the departure point mark in advance. There is no limitation on the shape, data structure, contents, etc. of the departure point mark. Further, the departure point mark may be the head point of the movement locus.

  The distance information output unit 132 outputs the distance information acquired by the distance information acquisition unit 124. The output mode of distance information does not matter. The output mode of the distance information may be a number or a symbol such as a bar.

  The storage unit 11, the map information storage unit 111, and the departure position information storage unit 112 are preferably non-volatile recording media, but can also be realized by volatile recording media. The process in which information is stored in the storage unit 11 or the like is not limited. For example, information may be stored in the storage unit 11 or the like via a recording medium, information transmitted via a communication line or the like may be stored in the storage unit 11 or the like, Alternatively, information input via the input device may be stored in the storage unit 11 or the like.

The processing procedure of the departure position information acquisition unit 121 is usually realized by software, and the software is recorded on a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  The output unit 13, the map information output unit 131, and the distance information output unit 132 may or may not include an output device such as a display or a speaker. The output unit 13 can be realized by output device driver software, or output device driver software and an output device.

  Next, operation | movement of the map output apparatus 1 is demonstrated using the flowchart of FIG.

  (Step S201) The departure position information acquisition unit 121 determines whether it is time to perform departure position information acquisition processing. If it is time to perform the departure position information acquisition process, the process goes to step S202. If it is not time to perform the departure position information acquisition process, the process returns to step S201.

  (Step S202) The departure position information acquisition unit 121 acquires departure position information. The departure position information acquisition unit 121 accumulates the departure position information in the departure position information storage unit 112.

  (Step S203) The map information acquisition unit 123 acquires map information including departure position information. Here, the map information acquisition unit 123 normally acquires map information of a default scale from the map information storage unit 111. The map information acquisition unit 123 holds default scale information in advance. The default scale may be the initial value of the scale, or the scale of the map that was displayed last.

  (Step S204) The map information output unit 131 outputs a map using the map information acquired in step S203.

  (Step S205) The output unit 13 outputs a departure point mark at a position on the map indicated by the departure position information. The departure point mark is a mark indicating the departure point.

  (Step S206) The current position information acquisition unit 122 acquires current position information.

  (Step S207) The determination unit 1233 determines whether or not the current location indicated by the current location information acquired in Step S206 and the departure location indicated by the departure location information are in a predetermined positional relationship. If it is in the predetermined positional relationship, the process goes to step S212, and if it is not in the predetermined positional relation, the process goes to step S208.

  Note that the determination unit 1233 determines, for example, whether the current location indicated by the current location information acquired in step S206 and / or the departure location indicated by the departure location information exists on the map acquired in step S204. You may judge. In such a case, if it exists on the map, go to step S212, and if not, go to step S208.

  (Step S208) The scale determining means 1231 determines the scale of the map including the current location indicated by the current location information and the departure location indicated by the departure location information.

  (Step S215) The processing unit 12 determines whether to end the process. If it is determined that the process is to be terminated, the process is terminated; otherwise, the process returns to step S206. For example, when it is determined that the vehicle has arrived at the departure point, or when an instruction to turn off the power is received, the processing unit 12 determines to end the processing.

  In the flowchart of FIG. 2, the map information acquisition unit 123 acquires map information after determining the scale of the map to be output. However, the map information acquisition unit 123 may update the map information so that a map including both the departure point and the current point is output.

  Hereinafter, a specific operation of the map output device 1 in the present embodiment will be described.

  Now, it is assumed that the map output device 1 is a map output device for a water moving body. The map output device 1 has a first mode for outputting a map that always includes the departure point and the current point. Note that the map output device 1 does not need to output both the departure point and the current point in modes other than the first mode. In addition, the mode is switched according to a user instruction.

  Further, it is assumed that the map information storage unit 111 stores a map of a scale of two or more stages.

  In such a situation, it is assumed that the user turns on the engine of the water moving body on which the map output device 1 is mounted.

  Then, the departure position information acquisition unit 121 determines that it is time to perform the departure position information acquisition process.

Next, the departure position information acquisition unit 121 acquires the current position information (x ₁ , y ₁ ) using the GPS receiver provided. This position information (x ₁ , y ₁ ) is departure position information. Then, the departure position information acquisition unit 121 accumulates departure position information (x ₁ , y ₁ ) in the departure position information storage unit 112.

Next, the map information acquisition unit 123 is map information including departure position information (x ₁ , y ₁ ), and acquires map information of a default scale from the map information storage unit 111.

  Next, the map information output part 131 outputs the map shown in FIG. 3 using the acquired map information.

  Next, the output unit 13 outputs the departure point mark 31 at the position on the map indicated by the departure position information. Reference numeral 32 denotes a water moving body. Here, it can be said that the departure point mark 31 is a current point mark. It may also be said that 32 is also a current location mark.

Next, it is assumed that the user has driven the water moving body and traveled on the sea. Then, it is assumed that the current position information acquisition unit 122 has acquired current position information (x ₂ , y ₂ ).

Next, the determination unit 1233 determines that the current location indicated by the acquired current location information (x ₂ , y ₂ ) and the departure location indicated by the departure location information (x ₁ , y ₁ ) are in a predetermined positional relationship. Judge whether there is. Here, it is assumed that the determination unit 1233 determines whether or not the current location indicated by the current location information and the departure location indicated by the departure location information exist on the output map. Then, the judging means 1233 has the current location indicated by the current location information (x ₂ , y ₂ ) and the departure location indicated by the departure location information (x ₁ , y ₁ ) on the output map (predetermined in advance). It is determined that the positional relationship is satisfied.

  Next, the output unit 13 outputs the current location mark on the output map. Here, the current point mark has the same shape as 31.

Next, the distance information acquisition unit 124 acquires distance information between the departure point and the current point using the departure position information (x ₁ , y ₁ ) and the current position information (x ₂ , y ₂ ). The distance information here is a linear distance.

  Next, the distance information output unit 132 outputs the acquired distance information. An example of such output is 401 in FIG.

  Then, it is assumed that the user drives the water moving body and proceeds on the sea. Then, the current position information acquisition unit 122 continuously acquires new current position information one after another. Then, each time the current position information is acquired, the determination unit 1233 determines whether the current location indicated by the current location information and the departure location indicated by the departure location information are in a predetermined positional relationship. .

  And when the situation which has a predetermined positional relationship continues, the output map is not updated. Then, the output unit 13 advances the current location mark on the output map and outputs the current location mark. Moreover, the output part 13 outputs the movement locus | trajectory of a surface moving body with a line. The movement trajectory of the water moving body is, for example, 402 in FIG.

Next, it is assumed that the current position information acquisition unit 122 has acquired new current position information (x _n , y _n ).

Next, the determination unit 1233 determines that the current location indicated by the acquired current location information (xn, yn) and the departure location indicated by the departure location information (x1, y1) are not in a predetermined positional relationship. That is, the determination unit 1233 determines that both the current location and the departure location are not displayed on the currently output map.

Next, the scale determining means 1231 determines the scale of the map including the current location indicated by the current location information (x _n , y _n ) and the departure location indicated by the departure location information (x ₁ , y ₁ ).
