Description

  The present invention relates to a system for producing spatial data related to geographic information, and more particularly to a spatial data production base system used in a photogrammetry relation. Further, the present invention relates to a spatial data production base system characterized by a process of structuring and editing spatial data related to geographic information, and a method for producing the spatial data.

Conventionally, spatial data related to geographic information has been obtained from the GIS geographic information system (G
IS: G o og a ph ic In fo t ima t i s yn s s tem (), it will be used for many purposes with the development and dissemination of the spatial data Various spatial data production systems for production and subsystems used in the spatial data production system have been proposed.

Since the spatial data includes necessary information regarding geographic information, the handling of the spatial data is wide, and it is used for various types of data, but it has a possibility of further development. For example, I
Information for grasping or guidance of traffic information in the Ts Intelligent Transport System (ITS: Int ile ig nt s s nt s t s s tem) In addition, it is used for emergency response support for disasters such as earthquakes, and geographical information about lifelines such as the status of lifeline facilities.

  The production of the useful spatial data is basically performed by combining various available subsystems according to the purpose of use, and this combination is performed using labor. Not only that, but because there is a need for manpower, there are many input errors or it is very expensive.

Basic and typical spatial data, for example, for photogrammetry, are used alone or in appropriate combination with subsystems such as a photogrammetry mapping system, a graphic editing system, and an attribute editing system, depending on the purpose. . These subsystems include the well-known CA
D system or GIS software is used.

However, recently, according to the penetration of geographic information standards, the CAD system includes complex attribute information including a variety of attribute information conforming to the geographic information standards because the data format is designed for graphic operations. Spatial data cannot be processed sufficiently. The G
Although the IS software is useful because it can eliminate the disadvantages of the CAD system to some extent, it cannot be said that a complicated three-dimensional shape mapping or editing function is sufficient.

Various subsystems and combinations thereof are known. For example, as a specific example, there is “height reproduction method three-dimensional digital mapping” provided by Asahi Koyo Co., Ltd.
Examples of combinations of subsystems are described in 0 0 4-0 3 8 0 4 4 (Patent Document 1), Japanese Patent Application Laid-Open No. 10-3 1 2 4 5 2 (Patent Document 2), and the like.

  In addition, the spatial data structured editing system used in the process of structuring and editing the spatial data used in the spatial data production base system largely depends on labor, and problems such as erroneous operation of input, labor, Time was required and the overall spatial data production infrastructure system was not satisfactory in terms of efficiency.

  Various spatial data structured editing systems have been proposed. For example, Japanese Patent Application Laid-Open No. 1-2 4 8 4 7 3 (Patent Document 3) and Japanese Patent Application Laid-Open No. 1 1-12 0 3 3 2 (Patent Document 4). However, it is currently not available to satisfy and satisfy the product specifications required as spatial data.

JP 2000 4 0 3 8 0 4 4 Japanese Patent Application Laid-Open No. Hei 10 3 1 2 4 5 2 Japanese Patent Laid-Open No. 11-2 4 8 4 7 3 Japanese Patent Laid-Open No. 1 1-1 2 0 3 3 2

  In the spatial data structured editing system, an efficient spatial data structured editing system that reduces the burden on the operator as much as possible, can easily input the product specifications, and has very few erroneous operations is desired. It is rare. Further, there is a demand for a spatial data production base system that uses such a spatial data structured editing system as a base of a spatial data production system that is efficient as a whole, has few erroneous operations, and has high productivity.

  A spatial data production base system using a spatial data structured editing system including an editing operation process according to a rule base file corresponding to a product specification defined at least in part by a geographic information standard is extremely useful for solving the above problems. is there.

  Various processes related to the present invention will be described below, and the spatial data production base system including some characteristic processes together with the spatial data structured editing system is very effective. The geographic information standard is well known in this field, but was formulated by the Geospatial Information Authority of Japan.

  For example, the spatial data production base system further includes a step of creating a stereo image of an object related to a survey photo or geographic information using two different images using a 3D graphics library in the step of plotting, If the video is a photographic video, use a plotting system for producing spatial data, comprising at least a step of correcting lens distortion and a step of correcting by a shooting point and direction. In this case, not only the processing speed can be further improved, but also high-quality spatial data can be obtained.

The plotting system will be described in detail. Surveying stereo, for example, aerial photo stereo, is an appropriate two-way aerial photo taken along the flight line.
A screen is selected, and the difference between the shooting positions is used for stereo. Stereo video systems using photographic video have been practiced for a long time, and the theory is well known.

However, unlike ordinary stereo photography, for example, in aerial photography, the shooting point and shooting direction are generally poor in stability of the shooting position because of shooting from inside an airplane in flight. is there. Therefore, these shooting points (
The altitude, latitude, and longitude) and shooting direction information are usually recorded corresponding to each image, and the shot image is stored together with the information regarding the shooting state. G
PS (G lobal positon ing system) and I M
The development of aerial photography is great with the development of U (In er tia Meas ur ing U nit). This is also true for surveying photographs using a fixed camera on the ground, as the accuracy of photogrammetry has increased as the correction of the photographing position has developed.

For example, Japanese Patent Application No. 2 can be used as a method of selecting appropriate two images from among a large number of survey photo images.
What is described in detail by the applicant of this patent in 00 4-1 9 5 2 0 6 can be used. On the other hand, in the case of the object using spatial data, the load of selecting an appropriate one from a large number of videos is eliminated. However, survey photographs and the like originally have a large amount of data, so the load on the system that handles them is large, and various measures for reducing the amount of data are various, but not enough. For example, an object is created from the obtained spatial data for the purpose of editing, and the object is observed and edited. In this case, both the object and the handling have a large amount of information. There was a problem.

The plotting system enables stereoscopic viewing without using an intermediate file by using a widely known three-dimensional graphics library in the area of games and the like.
Alternatively, stereoscopic vision can be realized without requiring a radial distortion correction image. As the basic program of the plotting system to be used, a known program can be used, but the process of obtaining a stereoscopic image is known in the field of games and the like.
It is obtained by applying a dimensional graphics library. As the representative three-dimensional graphics library, O pen GL or Di
What is called r e c t X is known and is preferably used in the present invention.

  The two different images of the plotting system are two photographic images in the case of survey photographs, but in the case of an object related to geographic information, two virtual objects that are stereoscopically configured from the spatial data It is a statue. In the case of the virtual object image, since it can be configured to be stereoscopically viewed from various angles, editing can be performed with accurate judgment in the editing process. The virtual object may be a point, a line, a surface, or the like.

The plotting system uses intermediate files (such as epipolar images and radial distortion corrected images) for stereoscopic viewing, etc.
Therefore, the processing is fast and the capacity is small, so that the entire processing can be performed efficiently and in a short time. Therefore, even if the graphic system is incorporated into an integrated system such as a spatial data production system including the graphic system, an efficient integrated system can be constructed without increasing the capacity. Further, since the object can be stereoscopically viewed using the obtained spatial data, the spatial data can be easily corrected and confirmed, and the quality of the spatial data can be improved. In addition, since it is possible to easily stereoscopically view the object from an arbitrary viewpoint and line of sight, for example, by controlling an excessive feeling, it is possible to display a terrain shape or to grasp a space in accordance with a reduced scale, and to obtain spatial data It is very advantageous for quality improvement.

FIG. 1 shows a processing procedure and a flowchart of the stereoscopic function of the plotting system. 1
To 6 represent processing or process, 1

The operator uses the invention according to the prior application of the applicant of this patent application, and stereo pair image data 12 relating selection of two adjacent stereo pairs (left and right images) from a large number of image groups.
Choose the appropriate one. In the pasting step 2, the images of the selected pair are pasted as textures separately on the right and left sides, respectively, on the appropriate objects by, for example, orthographic projection, and left and right textured objects are obtained.

As in the case of aerial photographs, the shooting position and shooting direction at the time of shooting, in other words, the viewpoint and line-of-sight direction, respectively, indicate the flight direction at the time of shooting.
If the direction perpendicular to the flight direction X 1 in the flight plane is Y 1, the direction perpendicular to the plane is Z 1, and the angles formed respectively are κ 1, φ 2, ω, the viewpoint position (X 1, Y 2) , Z) and line-of-sight direction (κ
, Φ, ω) are separately filed in the external localization file 1 3.

In the stereo model generation step 3, the external localization file 1
Based on the information of 3, the textured object is represented by 3
A stereo image model is arranged in a three-dimensional virtual space. The stereo image model is data 3

This information is also used in the stereo drawing step 4 and is corrected by the viewpoint and the line of sight so that the stereo image can be stereoscopically viewed. Known 3
Using the dimensional graphic library, the stereo image can be displayed on the stereo monitor 4 without creating an intermediate file.
Draw directly at 0.

While the stereoscopic image displayed on the stereo monitor is stereoscopically viewed 2 1, the operator plots the spatial data to create new spatial data 1 6.
Is obtained. The new spatial data 1 6
Is the existing spatial data 1 4
Are stored in the same format.

The above is the process of making a survey photograph in stereo. Based on the spatial coordinate values of the objects included in the existing spatial data and the new spatial data, the object model generation step 5
Then, the desired spatial data is arranged in the three-dimensional virtual space, and the arranged spatial data is used as a three-dimensional object model.

The data 3 6 of the three-dimensional object model is corrected by two arbitrary viewpoints in the stereo rendering step 6 so as to be formed as a stereo pair, and the two different images are obtained.
Using the dimensional graphics library, the stereo monitor 4 0 is directly drawn without using an intermediate file. At this time, stereo stereoscopic vision 2 in a later process
1 to adjust the settings so that the operator can easily see them. For example, the position, color, intensity, etc. of the illumination light source are adjusted to adjust the contrast. Further, the visibility of duplicate data can be improved by adjusting the transmittance of the obtained object.

  The operator confirms or corrects an error in the spatial data used for the object while performing the stereoscopic view 2 1 of the object on the stereo monitor 4 0. At this time, since the object can be stereoscopically viewed from an arbitrary viewpoint, it is easy to check errors and improve the quality of spatial data.

Although not shown, a known three-dimensional graphics library is installed in the plotting system, and as described above, the stereo drawing step 4

The model generation function and layout adjustment function of the dimensional graphics library are used.

  In the field of photogrammetry, it is very efficient to use a single format in the surveying process, and the spatial data production infrastructure system can convert data between various processes. In addition, it is easy to add complicated information, and as a result, spatial data with wide applicability can be easily obtained.

In the present invention, the photogrammetry includes both an analog method and a digital method. For example, the photogrammetry is performed using an aerial survey camera mounted on an aircraft, and an object (
This is a survey that uses a photographic method, such as surveying (features) or surveying using the results of a fixed camera installed on the ground. Further, the photogrammetry process refers to a process from the information obtained by the survey until the spatial data is produced.

The single format is a format of a common data format in which data is shared throughout the entire process.
It is a text file based on ML (eXt ns ib er M a k u lp a ng u a ge), and various graphic information, attribute information, layer management information, stereo setting information, etc. More preferably, it includes object management information capable of managing these pieces of information. Particularly preferably, a file format capable of storing all elements of the text file in binary format is used together with the text file. The text file and the file format are capable of complete mutual conversion, and the file format is capable of high-speed data input / output even for a wide area and a large amount of data.

Since the text file is completely compatible with each other between the file formats, a preferred one of the structure of the text file is selected as a representative, specifically, at least, preferably, X
It is characterized by including an ML header, other headers, stereo setting information, attribute information, layer management information, graphic information, and object management information.

The X M L header makes an X L M declaration, but this property is configured to be lost when converted to the file format. Furthermore, at least DT D (Doc ment nt pe te ft init ion: document type definition) and X
Defined as an operational rule by defining SL (Se nt s ive stile-s het het langu a gue: extended style sheet language) It is.

  The other header is a declaration of the file, and manages the system version number of the spatial data production infrastructure system and the version number of the file.

The stereo setting information records the viewpoint information of the view, and can select a monocular orthographic projection, a monocular center projection, and a stereo mode, and a wire frame and a texture are selected.
It is described by nine floating point real numbers of YZ coordinate values and unit vectors indicating the upward direction of the camera. In the case of stereo, two sets are required.

The attribute information allows the user to freely define attribute fields and edit them on the spatial data production infrastructure system. In the attribute field, the data type, field name, annotation character string, initial value, and the like are defined. Data type (
Pool, integer, single precision real number, binary, string, etc. can be selected.

The layer management information defines information relating to a layer that is a unit of data editing, and includes layer ID, layer name, group mode (group or non-group), group ID, display state (display /
(Not displayed) ・ Locked state (editable / locked / name cannot be changed)
Etc., and the link information of the stereo image pair is also recorded.

The graphic information is defined so as to correspond to all graphic elements that can be input and edited in the spatial data production infrastructure system. The graphic elements that can be handled include simple vertices, point clouds, vectors (
Array), single line, continuous line, arc, elliptical arc, circle, ellipse, face, triangular mesh (
TIN), polygon text (three-dimensional solid character string), label, group (parent-child relationship, number of subjects), and the like. The graphic element is an object I

The object management information manages the stereo setting information, the attribute information, the layer management information, the graphic information, and the like.
D, and the object I
D manages all objects using I D as a key.

  In the present invention, preferably, a single format is used as described above. However, in addition to the drawing step, it is more effective to include a step of assigning attributes and a step of assigning relationships between figures. Such a spatial data production system was not known. As a result, the obtained spatial data has much higher utility value and application value, and the process efficiency can be improved and high-quality spatial data can be obtained.

The step of drawing is a step of using what is generally called a drawing system, which is also called vectorization (Vectoorize), and is the shape, contour, or feature of a feature or road. This is a step of converting a point into digital data using a graphic element such as a surface, a line, or a point. For example, “Interpretation” provided by Asian Navigation, “Map Master”, Mitsui Construction Co., Ltd. (
Various systems are provided by Topcon Co., Ltd., but a three-dimensional system is preferably used. However, it is preferable to use the one converted so that it can be used in the single format.

The step of assigning the attribute is information on the attribute of the plotted data (information on the type and property of a feature such as a building or a road)
In the past, GIS software was used in the present invention. However, in the present invention, it is preferable that this be operated in the single format. is there. It is desirable that the drawing step is a three-dimensional one and has a stereo drawing function capable of stereoscopic viewing.

The step of providing the inter-graphic relationship is a relationship between the graphics (for example, whether or not the building graphics are in contact with each other at any point or face).
In the past, GIS software was used in the present invention. However, in the present invention, preferably, the information can be used in the single format. Used.

  The spatial data production infrastructure system according to the present invention is preferably configured as described above. However, it is desirable that various processes be performed in conformity with a geographic information standard, so that the entire system is efficient. Can be.

  The data format of computer graphics, the data format of the G I S software, and the data format of the CAD system are mainly utilized, and the overall data format is used with extremely low frequency of use. The preferred data format according to the present invention eliminates the traditionally required and used data format for the construction of spatial data so that the deficient part is compensated for in the data format area of computer graphics. Since it becomes an enlarged one, it can be used very efficiently and usefully. As a result, each of the conventional data formats eliminates what is lacking and provides satisfactory results.

  Since the spatial data production base system is preferably configured as described above, it is possible to perform efficient processing with consistent processing while producing spatial data from information obtained by photogrammetry. Therefore, it is possible to shorten the time, reduce labor, reduce costs, prevent erroneous operations, add sufficient information, etc., so that not only the spatial data can be produced very efficiently, but also the application of the spatial data is expanded.

Let D, delete mark and attribute data be variables. The selection of the object type is applicable to all cases of information related to inter-graphic relationships among the graphic information, the attribute information, and the information using the same attribute data class. Therefore, in the spatial data production infrastructure system, the spatial data production infrastructure system in which the single format includes the object type selection of the object management information is a preferred embodiment of the present invention.

The object I D manages all objects using I D as a key. In addition, object types of points, lines, planes, texts, and the like are graphic objects, and the drawing process 5 in FIG.

At that time, the attribute is used as an object type in the step of assigning the attribute, and the relationship is used as the object type in the step of assigning the inter-graphic relationship.

  The layer to which the object belongs is defined by the object management information. Furthermore, attribute data corresponding to each object type can be accessed using the attribute data of the base object class.

As the graphic information 6 3, conventionally known classes and variables are used. FIG.
Is a table for displaying the attribute data class, attribute definition class, and attribute field class variables.

The attribute data class uses a front and rear linked list, attribute information, attribute data size, and attribute data as variables. Various attribute data can be managed by a flexible data structure utilizing the forward and backward bidirectional link lists. For example, the previous or next attribute data class (

The data storage structure (data structure) is described in the attribute definition set of attribute definition class and attribute field class. It is a size defined by the number of attribute fields and the field size, and can handle variable size attribute data.

The example of FIG. 2 is as described above, but a more specific example of the step of assigning the attribute and the step of assigning the relationship between figures is shown in FIG.

And the traffic signal attribute 6 6 are assigned to the object I D, the object name, the object type, and the like. Further, for example, the utility pole attribute 6
7 and the traffic light attribute 6 6 are attached (relationship giving 6 9) or the object relation between the utility pole attribute 6 7 and the sidewalk attribute 6 8 is embedded (
Grant relationship 7 0).

  Another example using a single format is shown in FIG. FIG. 9 is a flowchart for creating spatial data compliant with the geographic information standard from aerial photograph image data, and is basically the same flow as FIG. Enter the process of plotting from the aerial photo image data 7 2, perform plotting 7 3 for stereo stereoscopic vision, go through graphic editing 7 4, and use the existing document 8 2 to edit field supplementary surveying survey 75 Go to the step of assigning the attribute, and edit the attribute 7 6 using the existing material 8 2. Next, the step of assigning the inter-graphic relationship is entered, and the inter-graphic relationship editing 7 7 is performed using the existing material 8 2.

Step 7 3 to step 7 7 are the next step 7 3.
In addition, a single format of the data file 8 1 of the spatial data production base system is used. The single format is shown in FIGS.

  After the editing step 7 7, the desired product is obtained at the product output 7 8, and the product specification 80 is referred to. As a result, spatial data conforming to the geographic information standard is obtained. High quality, efficient and error free products are obtained.

The spatial data production infrastructure system according to the present invention has a rule-based user interface (as an operation menu for guiding an operator who performs complicated plotting and editing work conforming to the geographic information standard (
RBU-I / F) is used. The rule-based user interface is a mechanism for controlling function restrictions of applications, and in the present invention, in particular, according to the type of graphic data, it can be used as a graphic type that can give available editing functions or relationships between graphics. This difference is a constraint condition (
Rule) is a mechanism for describing. Based on the constraint conditions, an interface for restricting operations is provided, and a reduction in user's erroneous operations can be expected.

  FIG. 10 is an example of the rule base file that is a feature of the present invention. It is characterized in that it conforms to a geographic information standard, and according to the geographic information standard, at least a part of the product specification can be supported. Taking traffic lights as an example, individuality, geometry, topology, inheritance, properties, relationships and functions are written.

FIG. 1 1 is a diagram for explaining the mechanism, operation, and embodiment of the rule-based user interface used in the rule-base file. Rule-based program 1
0 4 is first displayed as edit menu 1 0 6 on the screen for graphic input editing, attribute input editing and relevance input editing 1
Let 0 8.

The operator 1 0 5 selects any editing function from the displayed editing menu. For example, the graphic input editing is selected. The rule-based program 1
0 4 refers to the feature names described in the schema 1 0 2 of the product specification 1 0 1 and acquires all the feature names. For example, in the feature name, there are a traffic signal, a road information board, a road sign, a post and the like as the point feature, and there are a track, a boundary line, an optical fiber and the like as the line feature. In addition, the side features include sidewalks, roadways, vacant lots, and tree-planting zones.

For the selected editing work, the names of features that can be worked on are extracted from the operation of each feature in the rule base file 1 0 3 and displayed in the list on the screen 1
0 8 For example, the operation value is acquired for all the features in the rule base file, and the feature having the description of the graphic input editing is extracted from the operation values and displayed in the list on the screen. The rule base file 1
0 3 is as described in FIG.

The operator then selects the feature displayed on the screen. For example, a traffic signal is selected. According to the selection, a processing function necessary for the selected feature is acquired, and the rule base program 1 is selected for the selected feature.
0 4 obtains a type from the rule base file 1 0 3, obtains a data type, and further obtains a property and a subject attribute from the rule base file. Also, the rule-based program 1 for the selected feature
0 4 acquires the function and the operation attribute from the rule base file 1 0 3. For example, the traffic signal type is a point feature, and it has properties such as administrator, installation period, applicable structure decree, acquisition level and data validity period, and functions such as point arrangement, relevance assignment and attribute editing. Have.

The rule-based program 1 0 4 has the product specification 1 for the acquired data type, subject attribute, and operation attribute.
A possible value is acquired from schema 1 0 2 of 0 1, figure attribute 1 1 0, subject attribute 1 1
1 and operations 1 1 3 are defined respectively.

Further, the rule-based program 1 0 4 acquires a feature that can have a relationship with the selected feature. At this time, the rule base file 1 is selected for the selected feature.
Relevance is acquired from 03, and a feature that can have the relationship is acquired. For example, the features to which traffic signals can relate are in this case pillars, lighting facilities and three-dimensional crossing facilities.

The rule-based program 1 0 4 is the product specification 1 0 for features that may have the relationship.
The relation attribute is acquired from the schema 1 0 2 of 1 and the relation 1 is obtained as a feature having the relation.
1 2 is defined.

  The rule-based program 1 0 4 protects elements other than the operable elements, and protects those other than those defined as the features having the relationship so that they cannot be edited. For example, in the example of the traffic signal device, only the pillar, the lighting facility, and the three-dimensional crossing facility are locked so that they cannot be edited.

In accordance with the function menu 1 0 7, the rule-based program 1 shows the content obtained for the processing function necessary for the selected feature and the content obtained for the feature that may have the relationship.
0 4 is displayed on the menu so that the operator can operate it. In the above-described rule-based user interface mechanism, operation, and embodiment, the various processes are processes 1.
It takes place at 0 9.

  The operator performs input, editing, and deletion operations within the range of the operable features obtained by processing in this way and the provided functions, but protects unnecessary operations based on the product specifications. By doing so, the user's erroneous operation is reduced, and high-quality data can be obtained efficiently.

Since the spatial data production infrastructure system according to the present invention is as described above, it is easy to use by the user, has few erroneous operations, is efficient, can greatly shorten the editing work, and can shorten the delivery time. High-quality spatial data can be obtained. In addition, since the product specifications are available, the consistent spatial data production base system (including the spatial data structured editing system and the mapping system of the present invention) has the advantage of being accurate, excellent in product quality, and low in cost. Have Other effects are also clear from other descriptions.

  As the 3D graphics library, aerial photo image data 1 2 1 (7 2 in FIG. 9), photogrammetric plot 1 2 3 (7 3 in FIG. 9) and graphics are used. Involved in Edit 1 2 4 (7 4 in FIG. 9). For this reason, the edit integration function 1 3 4 for stereoscopic vision is involved in the spatial data data file 1 3 0.

  The spatial data production infrastructure system according to the embodiment of FIG. 12 develops a data format specification that covers specifications that can be defined by a geographic information standard that is a standard specification for spatial data exchange, and features that are not defined due to operator error. Alternatively, it is possible to prevent the input of data formats and attributes that are not defined, and by clearly formulating data format specifications, it has become possible to handle a wide variety of product specifications. In addition, since the rule-based user interface is realized, the operator's erroneous operation is reduced even in the case of complicated product specifications, and the quality of the finished product can be improved. In addition, it is not necessary to select the data definition or necessary operation function for each feature at the time of input and editing processing, and appropriate options according to the situation are displayed on the menu. You can learn editing operations in time. Further, stereoscopic viewing is possible without unnecessarily increasing the capacity, and further various stereoscopic viewing is possible, so that the quality of the obtained spatial data can be improved and errors can be further reduced. In addition, since the single formatting is used, there is an advantage that consistent and efficient processing can be performed, and also the effect of expanding the applicability of the obtained spatial data.
