Editing method of pedestrian network information

The invention relates to an editing method and a system thereof, in particular to a method for editing a pedestrian network information and a system thereof.

The Global Position System has been widely used in the navigation of traffic vehicles. In particular, car navigation is almost the most popular electronic product in recent years. According to the statistics of research institutions, the global navigation device (Personal Navigation Device, PND) The population of the population will grow from 1.79 million in 2009 to 134.31 million in 2014, with an annual growth rate of 99.2%. The popularity of navigation devices is thus visible. In recent years, with the increasing accuracy of satellite positioning technology, navigation devices have been further extended to pedestrian navigation.

However, the route that pedestrians can take with cars, the flexibility of road use, and the speed limit are very different. It is necessary for pedestrians to safely and unimpededly use the 4 navigation devices, and make good use of trails, shortcuts, building passages, etc. To open the sun and rain, we must rely on the huge but delicate maps of pedestrians, in order to truly play the advantages of pedestrian navigation.

As mentioned above, since the map data for pedestrian navigation is much more complicated than that for car navigation, the method of building it is also much more difficult. It requires an efficient and meticulous editing tool for route drawing, and the current map data editing tool is mainly used for drawing. Car navigation routes are used, and the characteristics and attributes of the pedestrian route cannot be expressed delicately, so it is necessary to find a solution.

Accordingly, it is an object of the present invention to provide an editing method for pedestrian network information that can improve editing efficiency and confidentiality.

Therefore, the editing method of the pedestrian network information of the present invention is performed on a computer device, and the computer device performs the following steps: First, a processing module loads a frame from a memory module. Then, a display module presents the frame. Furthermore, an input module receives a plurality of drawing instructions for the processing module to draw a pedestrian network including a plurality of pedestrian routes according to the drawing instructions, and set an initial value of the data corresponding to the plurality of pedestrian routes. . Then, the input module receives a plurality of first setting commands, so that the processing module sets the data after the editing of the pedestrian routes according to the first setting instructions, so that the data is set to a plurality of pedestrian facilities, a plurality of virtual links, and a plurality of Indoor passage. Then, the input module receives a plurality of second setting commands, so that the processing module sets the data after the editing of the pedestrian routes according to the second setting instructions. Furthermore, the processing module loads a vehicle road network from the memory module, and merges the pedestrian network into a combined road network. Then, the processing module detects whether the pedestrian route and the route of the combined road network comply with a check rule. Then, if the processing module detects that the combined road network complies with the checking rule, the processing unit stores the combined road network in the memory module.

The function of the invention is to use the detailed setting steps to edit the complicated pedestrian route and its subsequent data step by step, and use the verification rule to verify the correctness of the pedestrian route and the subsequent data to ensure the pedestrian network is correct. .

The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments.

Referring to Figures 1 and 2, a preferred embodiment of the method for editing the pedestrian network information of the present invention is a computer program executed on a computer device 1. In the preferred embodiment, the computer device 1 is a person Computer or a computer server. If executed on the computer server, the editor must connect to the computer server through a computer terminal for editing. In addition, if a collaborative operation is used, multiple editors can connect to the computer server through multiple computer terminals and edit at the same time. The technology of collaborative work has been widely used in the editing system of online operations, and will not be described here.

The computer device 1 includes a memory module 11 , an input module 12 , a display module 13 , and a processing module 14 . In the preferred embodiment, the memory module 11 is a memory function and a hard disk drive having a storage function for pre-storing a frame and a corresponding road network. In the preferred embodiment, the input module 12 is a keyboard, a mouse, etc., for the editor to input commands. The display module 13 is a screen in the preferred embodiment for displaying a picture. The processing module 14 is connected to the memory module 11, the input module 12, and the display module 13. In the preferred embodiment, the processing module 14 is a motherboard including a central processing unit. The computer program causes the computer device 1 to perform the following steps: First, as shown in step 21, the processing module 14 loads the frame from the memory module 11. Wherein, in the preferred embodiment, the image is an aerial image map including a plurality of blocks. Before the step 21 is performed, the frame may be first loaded by the processing module 14 from the memory module 11 for the editor to use the input module 12 to add annotations to the frame and each block thereof, and then store the image. To the memory module 11. The purpose of adding annotations is to record the features of the frame and its blocks for subsequent steps, so that subsequent editors can quickly understand the characteristics of the frame and its blocks. In addition, when the processing module 14 loads the image, the memory module 11 can also load a road network corresponding to the frame, and the road network is drawn by a complex vectorized vehicle route. It is also the way to form an existing electronic map.

Then, as shown in step 22, the display module 13 displays the frame 3 as shown in FIG. 3, and the toolbars and windows (not shown) for the plurality of editing are also presented in the display module 13. Editors choose. If necessary, the processing module 14 can display the driving route 31 of the road network corresponding to the frame through the display module 13 for the editor to refer to.

In addition, as shown in step 23, the processing module 14 receives a plurality of drawing instructions through the input module 12, and depicts a pedestrian network including a plurality of pedestrian routes, wherein each pedestrian route has a post-set data, and When these pedestrian routes are drawn, the initial values of the subsequent data are also automatically set. In the same manner as the aforementioned roadway network, in the preferred embodiment, the pedestrian routes are complex vectorized segments.

In the preferred embodiment, each of the pedestrian routes records the post-data in the memory module 11 in the form of a field of the database, and the post-data has a type attribute, a status attribute, and an aisle attribute. a step attribute, a step lift attribute, a foot attribute, an indoor mark attribute, a floor attribute, a departure floor link attribute, an arrival floor link attribute, a directional attribute, a restricted pass date attribute, and a restricted pass time attribute , a masking attribute and a masking scale attribute, but not limited to this, according to the characteristics of each pedestrian route, more attributes can be added. Table 1 shows the post-setting data of each pedestrian route in the preferred embodiment. Each attribute can be set to a corresponding value through the input module 12. In practical applications, the navigation software can be based on the pedestrian network. The post-set data is used as a reference indicator for automatic path planning.

As described above, in order to increase the simplicity of the operation, after each pedestrian route is drawn, the processing module 14 automatically sets the post-set data of the pedestrian route, and its attribute is first set to the preset value, with the type attribute. For example, the default value is "PD" (Pedestrian Lane, as shown in Table 2), and in the case of the ladder attribute, the default value is "N". If the pedestrian route is a stepped sidewalk, the editor can edit the ladder attribute value of the pedestrian route to "Y" and the step elevation attribute to "0" for setting. Among the ladder lifting attributes, 0 means that there are upper and lower steps in the pedestrian route, 1 represents the upper step, and 2 represents the lower step.

Except for the pedestrian-only road for pedestrians to walk, the roads that are regarded as lanes and roads can also be used by pedestrians. Therefore, the above-mentioned road routes also have such post-design materials, which can be edited to record their The characteristics of pedestrians. As shown in FIG. 4, if the road route 313 is a lane, that is, the road route 313 is not only for vehicles, but also allows pedestrians to walk, the editor can edit the type attribute of the road route 313. The value is "AL", the value of the status attribute is "39" (1+2+4+32=39, as calculated in Table 3), and the value of the aisle attribute is "LEFT_RIGHT" to set the route of the vehicle. 313 is the sidewalk shared by the vehicle and pedestrians.

If one of the lanes 311, 312 is a two-way road with a wide width, such as a provincial road, it is not only for vehicles, but there is no special sidewalk on the two sides of the road, but it can still be used for pedestrians to walk. The editor can edit the value of the type attribute of the vehicle route 311, 312 to "1W" and the value of the status attribute to "63" (1+2+4+8+16+32=63, as shown in Table 3). The value of the calculation) and the value of the aisle attribute are "RIGHT" to set the right side of the route 311, 312 for pedestrians to walk.

Referring to FIG. 1 and FIG. 2, then, as shown in step 24, the input module 12 receives a plurality of first setting commands, and the processing module 14 prepares the data after the editing of the pedestrian routes according to the first setting instructions. It is set up as a plurality of pedestrian facilities, a plurality of virtual links, and a plurality of indoor passages.

One of the first setting commands, by editing the value of the walking attribute, is used to set each pedestrian route as a sidewalk of a specific facility. As shown in FIG. 5, if an intersection has eight sidewalks 323 and four sections of zebra crossings 324, the editor can edit the value of the zebra crossings 324 to the zebra crossing to set the zebra crossings in the pedestrian lanes. .

Another first setting command is to edit the value of the walking attribute as a "virtual link" to set certain pedestrian routes as crossings of a particular facility. As shown in FIG. 6, according to the frame, the intersection 42 can traverse the park 41 to the intersection 43, and the editor can edit a pedestrian route 44 connecting the intersections 41, 42 at both ends, and the hiking attribute of the pedestrian route 44 The value is "virtual link". In addition to the park 41, such as the shopping center atrium, the lobby of the first floor of the government agency, etc. may be in line with the characteristics of pedestrian crossing.

A first set of instructions is used to construct a complex indoor passage. As shown in FIG. 7, if one of the pedestrian routes 51 is a section of the indoor passage, the editor can edit the value of the indoor marker attribute of the pedestrian route 51 to "Y", and the value of the floor attribute is "1" to set the pedestrian line. Route 51. As shown in FIG. 8, the first floor 61 has the pedestrian route 611 and an elevator facility 612. The second floor 62 has the pedestrian route 621 and an elevator facility 622, if from the first floor 61 to the second floor 62. The pedestrian route 63 must pass through the elevator facilities 612 and 622, and the editor can edit the value of the indoor marker attribute of the pedestrian route 63 to "Y", the value of the departure floor connection attribute is "1", and the value of the arrival floor connection attribute. It is "2" and the floor attribute is canceled to set the pedestrian route 63. In addition, such as escalators and stairs can be set in the above manner.

Then, the input module 12 receives a plurality of second setting commands for the processing module 14 to edit the data according to the second setting instructions.

One of the second setting commands is mainly used to mark whether the pedestrian route has the characteristics of sunshade and rain. The value of the masking attribute of the edited pedestrian route is "Y" and the value of the masking scale attribute is "10", which is used to set a specific pedestrian route to have a sunshade effect. Among them, the value of the occlusion ratio attribute is determined according to the actual appearance of the pedestrian route. For example, the awning can be completely shaded and protected from rain. The shielding proportion attribute can be set to "10", but the flower scaffolding can only partially shade the rain, depending on The effective shielding effect can be set to "1" to "9".

Another second setting command is mainly used to mark whether the pedestrian route has a transit time limit, such as a zebra crossing in front of the school and a crosswalk crossing that is open at a specific time. As shown in FIG. 6, FIG. 6 represents a road junction, and crossing lanes 325, 326 represent an intersecting pedestrian-specific multi-phase crossing. Assuming that the restriction of the crossings 325, 326 is only for pedestrians from 7:00 to 8:00, and from 14:30 to 16:30, the value of the first set of restricted transit date attributes (Day_1) is edited. "31" (see Table 4 from Monday to Friday), the value of the restricted traffic object is "63" (car, locomotive, pedestrian, truck, bus, bicycle), and the value of the item during the restriction period is "School_Day", The values of a set of restricted transit time attributes (Time_11, Time_12, Time13) are "00000700" (0 to 7), "08001430" (8 to 14:30), and "16302400" (16:30 to 24 points), the value of the second set of restricted transit date attributes (Day_2) is "96" (Saturday, day) and the value of the second set of restricted transit time attributes (Time_21) is "00002400" (all day).

Referring to FIG. 1 and FIG. 2, further, when the pedestrian route is newly completed, and the vehicle route is completed, as shown in step 26, the processing module 14 loads the vehicle road network from the memory module 11, The vehicle road network includes the information that has been recorded after the record, and the road network of the pedestrian network and the above-mentioned repaired road network is a combined road network. Among them, the combination of the road network and the pedestrian network is actually the integration of the database data, the same field will be consolidated into one, and the different fields will expand the fields that were not included in the original. In the road network part of the road, the vehicle road network first loaded in step 21 is mainly used to set the relevant attributes of pedestrian traffic. Therefore, in step 26, the relevant attributes of the pedestrian traffic on the road network and the traffic of the vehicle are The related attributes are consolidated here. The integration of the database is an existing technology and will not be described here.

Then, as shown in step 27, the processing module 14 detects whether the pedestrian route and the route of the combined road network meet a check rule. If not, the process module 14 generates the process as shown in step 28. A prompt message is displayed on the display module 13. The prompt message may be a text message, but is not limited thereto, and may be imaged on the pedestrian route and the route of the vehicle. The inspection rule includes a first item and a second item. The processing module 14 checks the sub-steps 271-274 shown in FIG. 9 according to the first item and the second item.

Referring to Figures 1, 2 and 9, as shown in sub-step 271, the processing module 14 detects whether the pedestrian routes of the combined road network and the route of the vehicles meet the first item, that is, the pedestrian routes and Whether the route of the car is one-to-one corresponds to one of the post-set materials. For example, a certain route is loaded in step 21 and set to set the data. However, in step 26, when the original data of the route is imported, the correction may occur due to a takeover error. The vehicle route corresponds to two sets of data, and the subsequent data has conflicting data settings. If the pedestrian route and the route of the vehicle cannot correspond to one of the rear-end materials, the processing module 14 generates a related prompt message for display on the display module 13 as shown in sub-step 281.

The second project has a checkpoint pedestrian route node subproject, a check geometry error error subproject, and a data subproject after a check. As shown in sub-step 272, the processing module 14 executes the check pedestrian route node sub-item, that is, whether the second endpoint of each pedestrian route or the vehicle route is less than one of the other pedestrian route or the route of the vehicle. The threshold value, if it is, indicates that the pedestrian route or the route of the vehicle should be engaged, but the connection is not properly connected due to the negligence of the drawing. Therefore, as shown in sub-step 282, the processing module 14 generates a related prompt message to display on The display module 13. In the preferred embodiment, the threshold value is 1 meter, that is, if the one of the pedestrian route or the route of the vehicle is within one meter of the other pedestrian route or the vehicle route within the true ratio, It means that it should be connected with the pedestrian route or the car route.

As shown in sub-step 273, the processing module 14 executes the check geometry error sub-item, that is, checks whether each pedestrian route and the vehicle route are completely overlapped, or one of the pedestrian route or the vehicle route and another pedestrian route When the route of the vehicle is intersected, whether the terminal is connected, if any of the above, the processing module 14 generates a related prompt message for display on the display module 13 as shown in sub-step 283. For example, if one of the pedestrian routes intersects with another traffic route, if it is not connected by the end point, it means that the pedestrian route is vertically interlaced with another vehicle route, like the intersection of plane roads and elevated roads. situation.

As shown in sub-step 274, the processing module 14 executes the data sub-item after the check, that is, whether the values of the attributes of the data after each pedestrian route and the vehicle route are checked are in compliance with the regulations. For example, the value of the Status attribute should be a combination of numbers such as 0, 1, 2, 4, 8, 16, 32, and so on. The value of the step attribute (Stair) should be "Y" or "N", and should not be null. If the value of the step attribute is "Y", the value of the step-up attribute (GradeDir) should be "0", " 1" or "2". Other attributes have their own specific rules, which can be determined by the requirements of the subsequent data. If the above is the case, the processing module 14 generates a related prompt message to be displayed on the display module 13 as shown in sub-step 284.

Referring to FIG. 1 and FIG. 2, if the processing module 14 detects that the pedestrian route and the route of the combined road network meet the verification rule, the processing unit 14 stores the combined network in the memory module. In group 11, the pedestrian route and the route of the combined route network have established the above-mentioned detailed post-set information, and the navigation software can use the post-set data as a reference for the route planning of pedestrian navigation, so that the user is familiar with The local road conditions are unimpeded in the local people. For example, sunny or rainy days are always planning to have rain-covered walkways, cleverly avoiding dedicated roads that are not available for pedestrians at specific times, and using virtual links to guide pedestrians directly through parks or buildings.

In summary, the present invention can systematically complete the complicated editing of the pedestrian network, and the subsequent automatic inspection operation can effectively produce the map for the pedestrian navigation, so that the object of the present invention can be achieved.

The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
