JP 2000-148209 A

  Since the above-mentioned maps that are generally marketed / distributed are prepared for healthy persons, the road route of the map itself can be recognized by the user for wheelchair users, but for wheelchair users. I can't recognize the slope of the road, that is, I can't recognize if I can go through the road shown on the map by a wheelchair, and I actually go to the road thinking that I can pass When I tried, there was a problem that there was a possibility that it could not pass.

  In addition, as a commercially available / distributed map, there are landmarks on the map in which the landmark name is written in Braille. For example, the location of the station and the location of the school on the map can be recognized. Even if it was possible, there was a problem that the route of the road between the landmarks could not be known. Also, the map is printed with a scale indicating the distance tomorrow at the end according to the scale, but the distance between landmarks cannot be recognized, especially for wheelchair users. There was a problem that it was difficult to recognize the distance required for traffic.

  Furthermore, there is a problem in that maps that are generally available on the market cannot obtain necessary information for color blindness or color blindness. Specifically, for example, a road such as a road or a railroad is drawn, and a plurality of landmarks such as a station, a park, a police station, etc. are arranged. Or, in the case of a color scheme that is unrecognizable by color blind people, the color blindness or color weakness cannot recognize the presence of the toilet.

  For this reason, the color blind person or the color weak person who referred to the conventional map recognized that the toilet does not exist in the park, and had the fault of saying that he would go out to the park. Especially for wheelchair users, confirmation of the existence of toilets that can be used in wheelchairs is an important issue when going out. .

  The first object of the present invention is to eliminate the above-mentioned problems caused by the prior art, and to provide a map information printing method and printing system for printing a barrier-free map. A second object of the present invention is to provide a diagram information printing method and printing system for printing a map that allows a blind person to recognize a road route between landmarks. A third object of the present invention is to provide a map information printing method and printing system for printing a map that allows a wheelchair user to easily recognize the inclination and distance of a road. It is a fourth object of the present invention to provide a map information printing method and printing system for printing a map with an easy-to-see color scheme, without being limited to the presence or absence of color blindness.

  In order to achieve the above object, the present invention prints map information that prints a map based on route information such as a road route, landmark information added to the route information, and height difference information corresponding to the route information. In the method, a map information database storing the route information and a height difference information database storing height difference information corresponding to the route information of the map information database are used. When the difference information is greater than or equal to a predetermined inclination angle, when generating a height difference mark representing the height difference for each route that is greater than or equal to the inclination angle, and printing the map information including the route using the route information and landmark information, A first feature is that a map is printed with a height difference mark attached to the route.

  In the map information printing method, the map information database includes data representing a roadway with a sidewalk, and when printing the map information, a plurality of protrusions protruding from the map along the roadway with a sidewalk. Printing the map information, the map information database includes distance data of a roadway with a sidewalk, and when the map information is printed, the land along the roadway with the sidewalk is printed. According to a third aspect of the present invention, the distance information between the marks is printed linearly on the edge of the map, and in any one of the map information printing methods, the color of the landmark information in the map information database causes color blindness. If there is a possibility, the color information correction definition database for changing the color information to other color information is provided, and the color of the landmark information is defined as a color information correction definition. Change in color is not caused color blind with reference to the database and fourth feature to print the map.

  Furthermore, the present invention provides a map information printing system that prints a map based on route information such as a road route, landmark information added to the route information, and height difference information corresponding to the route information. A map information database for storing, a height difference information database for storing height difference information corresponding to the route information of the map information database, and a control unit for controlling printing of the map with reference to each database, When the height difference information for each route of the route information in the map information database is greater than or equal to a predetermined inclination angle, the control unit generates an elevation difference mark representing the height difference for each route that is equal to or greater than the inclination angle, and the route information and When printing map information including a route using landmark information, a fifth feature is that a map is printed with an elevation mark added to the route.

  Furthermore, the present invention is the map information printing system, wherein the map information database includes data representing a roadway with a sidewalk, and when printing the map information, a plurality of protrusions protruding from the map along the roadway with a sidewalk. The map information database includes distance data of a roadway with a sidewalk, and when the map information is printed, a land along the roadway with a sidewalk is printed. According to a seventh aspect of the present invention, the distance information between the marks is printed linearly on the edge of the map. In any one of the map information printing methods, the color for changing the color information to other color information An information correction definition database is provided, and when the color of the landmark information in the map information database may cause a color blindness, the control unit may change the color of the landmark information.

<Description of configuration>

<Description of system configuration>
As shown in FIG. 1, the main configuration of a printing system that implements a map information printing method according to an embodiment of the present invention is route information (specifically vector information) / route information that is road information on a map. Station information or station information to be attached to the station / Color information to be added to the route information and landmark information (for example, “blue” for the station, “red” for the police), etc.) / Specificity associated with the landmark information and others Map information database 130 for storing information (for example, “station name”, “police name”, “tourism place name”, and other guidance texts) and information such as an inclination angle and direction at an arbitrary point by taking aerial photographs at different angles A map height difference information database 130 for storing information on the direction and angle of inclination of the designated or selected road based on the aerial photograph information 180 including the map information database; When the color of the 130 specific information may cause the above-mentioned color blindness (for example, red characters in the background blue), the color information correction definition database 150 for changing the color information to other color information, When the content of the specific information in the map information database 130 may cause color blindness (for example, fine characters), the change definition database 160 of the specific information content for changing the content of the specific information to other specific information; A print information database 170 for storing print information for printing a map based on the information stored in each of the databases 130 to 160, and a printing apparatus for printing a map using the map information stored in the database 170 190, a management server 110 that is connected to the outside via the public communication network 120 and controls the databases 130 to 160. Provided.

  As shown in FIG. 7, the map height difference information database 140 is designated or selected based on aerial photograph information 180 including information such as an inclination angle and direction at an arbitrary point by taking aerial photographs at different angles. For storing information on the direction and angle of inclination of a road, and a management number field for the road / an inclination start coordinate field for storing an inclination start coordinate value / an inclination end coordinate field for storing an inclination end coordinate value / Slope slope distance (m) calculated using trigonometry from the start and end coordinates of the slope / Slope angle calculated in the same manner (degree) field / Slope rate calculated by the slope angle (%) field / An inclination direction column indicating the direction of the inclination / the slope includes a specific information column for storing annotation information indicating that the wheelchair cannot pass, for example.

  For example, in the map height difference information database 140, in the road management number “A10031”, the distance from the coordinate (Xa, Ya) to the coordinate (Xf, Yf) is an inclined road, the distance is 20 m, and the inclination angle is 2 .8 °, the inclination rate is 4.9%, and the inclination direction is vector K.

  The data in the management number column / tilt start coordinate column / tilt end coordinate column is provided based on aerial photographs. In this embodiment, the server 110 uses the data to determine the slope slope. Each data in the distance (m) column / inclination angle (°) column / inclination rate (%) column / specific information column is calculated and stored. The items stored in the specific information column are, for example, a practical climbing angle of 6-10 degrees with a general electric wheelchair, 15 degrees at the maximum, and a practical climbing angle with a self-propelled wheelchair is 3-4 degrees. May be stored in a table (not shown) and automatically given when the value of the tilt angle column exceeds the table value, or road surface information such as unpaved roads may be obtained from the map information database 130 and stored. good.

  In the color information correction definition database 140, as shown in FIG. 6A, for example, the specific information changes “road note” to “dark blue”, and “border line between road and city area” changes to “black”. ”,“ Notes and leader lines for important information ”are changed to“ black ”, 20% yellow stitches are placed in important areas such as sightseeing spots, and“ highway ”is“ light green ” "National road" is changed to "Magenta (a color material that absorbs green light and reflects red light and blue light)". A correction table indicating a relationship with information is stored. In other words, the database 140 includes specific information indicating characters / lines / regions that are difficult to see even for people with color blindness, and colors that can be easily recognized by a normal person regardless of the presence or absence of color blindness. The relationship is stored.

  Other examples of correction definitions are: “Red” is changed to “Vermilion”, “Green” is changed to “Blue with strong bluish color”, “Purple” is changed to “Purple close to red”, “Vermilion” Three colors (red, orange, yellow) with different apparent brightness are allocated to the color between red and yellow, "blue color" is allocated to "light blue" and "blue", and "light blue and yellow fine lines" A definition that changes (including text) to “blue” is conceivable.

  The specific information content change definition database 160 stores the content of specific information that may cause color blindness and the content of change processing for the specific information. For example, as shown in FIG. If the specific information is “thin text”, it may be changed to “bold text”, and even if the color is changed using the color information correction definition database 150 according to the original color scheme included in the map information, it may lead to color blindness If there is a possibility that it may cause a sense of incongruity for a healthy person, for example, it is stored that an annotation character drawn with an arrow is added or a white character is changed without changing the character color . The annotation characters to be added are, for example, annotations and arrows by characters such as “wheelchair toilet”, and the determination that there is a possibility of causing a sense of discomfort for the healthy person is “color hue” and “saturation”. By making correspondence with “brightness”, a table such as a contrast that is easy for a healthy person to see / a contrast that does not feel uncomfortable is prepared, and the table can be easily determined by referring to this table.

  The present invention is intended for wheelchair users but also for color vision disorders, so these color vision disorders will be described. First, human vision recognizes colors by having three types of pyramidal cells that individually sense red / green / blue in the retina of the eyeball, but one type of the cone cells is lost. In this case, it is said that color blindness is caused, and that when one of the three types of sensitivity curves is shifted and close to the others, color weakness is caused. In addition, the color blindness may cause a mutation in a gene of a visual substance that feels red and a gene of a visual substance that feels green. Since the red and green visual substances have a large overlap of sensitivity curves, It is known that there is a slight difference in how the colors appear, although either of them can cause similar symptoms.

  In addition, the color blindness is not simply what color is difficult to recognize, and is different in appearance depending on the correlation between a specific color and other colors. '', `` Red '', `` red '', and `` blue '', for example, `` red '' becomes `` dark and sunken '', and the background is blue with `` red '' or brown with `` warm (blue) If there is "green" (which does not contain any), the whole appears brown and characters cannot be identified. This occurs, for example, when most of the text colors in the text are different from some text colors. Specifically, if “red” or “fine print” is present in the black text, It is known to be difficult to see.

<Description of operation>
The operation of the map printing system and printing method configured as described above will now be described with reference to FIG.
FIG. 2 shows a procedure for executing the map printing method according to the present embodiment. This processing procedure includes vector information indicating a route such as a road route, landmark information added to the vector information, and the like. Step 10 for acquiring map information consisting of color information to be added to the vector route information and landmark information, specific information including notes, and other additional information (tourist information and others), and based on the aerial photograph information 180 Step 17 for creating the map height difference information shown in FIG. 7 and the vector information obtained in Step 10 and the data obtained in Step 17 as inputs, and Step 18 for selecting road information through which people can pass from this vector information. And slope slope distance (m) / slope angle (°) / slope rate (%) column / slope direction / specific information column corresponding to the road management number stored above. To extract, to perform the steps 19 people on the map to grant the height difference mark to passable road information.

  As shown in FIG. 4, the height difference mark indicates the degree of inclination with respect to the road distance in%, and in the example shown, the road with an inclination of 0.4% continues for 40 m. The inclination may be changed to an actual inclination angle.

  Next, this processing procedure extracts color information from the map information obtained in step 10, for example, color information correlation including hue / saturation / lightness / color adjacent color relationship or background color relationship. Step 11 to be performed, color information correction processing step 13 referring to the color information correction definition database 150 described above based on the color information extracted in Step 11, and specification referring to the specific information content change definition database 160 described above By executing the change processing step 14 of the information itself, map data that can be recognized even by color blindness is created.

  In the present embodiment, the height difference mark created in step 19 and the map data subjected to color vision correction in steps 13 and 14 are added in step 15 to provide information on the inclined surface for wheelchair users. For the color difference mark and color blind persons, the map data corrected in color is used, and the map effective for these obstacles is printed in step 16 so that everyone can recognize and use regardless of the obstacles. Easy maps can be printed.

  As shown in FIG. 3, the printed map according to the present embodiment is a map 30 on which a plurality of landmarks 34 and roads 31 are printed. For example, a height difference mark 33c is added to the road 31c and [<< ] Or [>>] or the like indicating the direction, the distance of the road 31c is 142 m, the slope is 5.4%, and the direction is the direction from the right to the lower left of the drawing (<<). Can be printed. For this reason, it is possible for wheelchair users to know in advance the inclination of the road to be visited.

  In addition, the printed map according to the present embodiment has a color scheme changed to a color that is difficult to cause color blindness even for color blindness, so that it is easy for color blindness to recognize the contents of the map. it can.

  Furthermore, although only the map information to be printed has been described in the above embodiment, the present invention is not limited to this, and for example, the color described in the above embodiment for map information displayed on the Internet or a mobile phone. In this case, the embodiment stores the definition information for converting the print information database 170 in FIG. 1 to be displayed on the Internet browser or the small screen of the mobile phone. Instead of the display information database, the map display information converted for screen display based on the display information database can be transmitted through the public line network.

  FIG. 8 is a diagram for explaining a map according to another embodiment of the present invention. The map according to the present embodiment is designed so that a blind person can recognize a landmark such as a station when printing the map. Braille representing the mark name, and the large convex part 70 and small convex part 71 for a blind person to recognize the route from the station to the school, for example, and a person who can see easily recognize the distance between the landmarks A distance guide column 60 between landmarks is provided. In FIG. 8, the illustrations common to those in FIG. 3, such as the tilt marks, are omitted because the drawings are complicated.

  First, the road on the map will be described as a premise in order to explain the convex portion. The road in this example has a lane at the center and a lane 40 with a sidewalk provided with sidewalks on both sides of the lane, and a lane with a sidewalk provided at the center and a pedestrian path only on one side of the lane. 41 and a general road 42 in which there is no particular distinction between a roadway and a sidewalk. The reason for distinguishing these three types of roads is that, even if the general road 42 is distinguished from a pedestrian traffic area and a car traffic area by, for example, a white line, for wheelchair users and blind people, While the traffic area is narrow and it is difficult to ensure safe traffic, the sidewalks and roadways 40 and 41 are separated by steps, guardrails, etc., and wheelchair users and blind people For this reason, in consideration of the fact that the road can be expected to be relatively safe, these dangerous roads are distinguished from relatively safe roads.

  The map according to the present embodiment stores the type data indicating the type of the road in the map information database 130 shown in FIG. 1, and when printing the map information, the map has a large convexity along the road 70 with sidewalks on both sides. The small convex part 71 is projected on the road 70 with the part 70 and the one-way sidewalk along the road, and is formed by printing using a special transparent curable ink. Similarly, each landmark is provided with its landmark name, for example, the school name of the school 51 in Braille 51t, the park name of the park 52 is provided in Braille 52t, and the police signature of the police 53 is as Braille 53t. It is formed by printing with a special transparent curable ink.

  When this map is used by a blind person, the relative positions on the map of a plurality of landmarks are recognized by, for example, interpreting the landmark names by hand touch, for example, the station 53 and the school 51 are braille. A relatively safe route can be understood by interpreting the position with 51t and 53t and then recognizing the position, and then tracing the path connecting the two with the large convex portion 70. Similarly, the route from the station 53 to the park 52 can be understood as a relatively safe route by tracing the large convex portion 70 and the small convex portion 71. The landmark names may be printed as a list together with visible characters at the end of the map, for example.

  Next, the distance guidance column 60 will be described. This distance guide column 60 linearly represents a distance on a route that actually passes between a landmark, for example, a route that reaches the school 51 from the station 53 via the police 53, as shown at the right end of FIG. Specifically, the distance (70 m) on the route from the station mark 61 that is the departure point to the top and the police mark 62 on the route and the distance (45 m) on the route to the police mark 62 are printed. It is a thing. This printing can be formed by storing the distance data of the road with a sidewalk in the map information database 130 and printing it at the end when the map is printed. In addition, in the area 64 of the distance guidance column 60, it may be displayed that a Braille block exists on the road / paved or unpaved. Further, the distance guidance column 60 may be provided in the horizontal direction according to the arrangement of landmarks in the map.

  The distance guidance column 60 is easy to recognize because the conventional scale is simply a linear distance scale, whereas the distance actually required by a person is arranged linearly between landmarks. Particularly for wheelchair users, it is important to recognize the distance required for actual traffic. In addition to the height difference marks described in the above embodiment, the height of the road to the landmark that the user wants to go from now on It is possible to easily obtain information for determining whether to use a taxi or the like, or to require an assistant, considering the difference, actual distance, own physical strength, and the like. The convex or braille printing is not limited to transparent and curable ink.For example, microcapsules containing a material that thermally expands by heating are contained in normal ink or provided in a base layer of paper, You may form by expanding the said microcapsule by irradiation of a laser beam.

  In addition to maps issued by public institutions, tourism associations, etc., the present invention can also be applied to tourism maps for mainly guiding landmarks such as city centers and tourist facilities. It can also be applied to the creation of maps on the web that sighted people can distribute over the Internet.
