Description

The present invention relates to a spatial object pointing device, and more particularly, to a pointing device for a spatial object capable of specifying a real or virtual spatial object at an aimed point by aiming at a space.

In general, spatial positional information about a real or virtual spatial entity existing in a space is obtained as a map. In addition to the positional information, the map may include various information including the name of the spatial object. Hereinafter, the term spatial object is to be used in the broadest sense, and has a meaning in relation to space as a virtual concept such as traffic accidents, migratory birds, typhoon movement routes, as well as artificial or natural objects in the real world. It shall include even.

It can be said that GIS extends the concept of the map and constructs more systematically. GIS (GIS) is a computer application system that efficiently collects, stores, analyzes and outputs spatial data. For example, various fields such as buried property management, location selection of major facilities, real estate information, and disaster prevention Increasing usability. GIS is developing into the core of ubiquitous information infrastructure through popularization, industrial standardization of open GIS, componentization of GIS, Internet-based GIS development, and field integration with CAD / CAM.

On the other hand, GPS can be cited as the location information of a certain point. GPS uses DGPS (differential GPS) to reduce the error range to within 1-5m, and it is already used in navigation and other products.

Hereinafter, the configuration of the present invention in detail with reference to the accompanying drawings. However, the components having the same function by the same configuration may be omitted because the same reference numerals are kept even if the drawings are different.

According to the present invention, a mouse, which is a pointing device, specifies a plane object such as an icon on a computer screen, and performs a process of copying or deleting the specified plane object. Specifically, the present invention relates to an apparatus capable of performing an inquiry, upload, or the like, on a specified spatial object.

1 is an exemplary block diagram of a hardware block configuration of the spatial object pointing device of the present invention, and FIG. 2 is a flowchart illustrating an overall flow in which the spatial object pointing device of the present invention operates.

The space object pointing device of the present invention includes a space object aiming means (110), a space object specifying means (130), and a space object processing means (140).

The spatial object aiming means 110 is a means for obtaining physical geographic information by aiming the spatial object 20 at the reference point 10 toward the spatial object 20.

The reference point 10 is an arbitrary first point on the three-dimensional space. The spatial object 20 is located at another second point conceptually separated from the reference point 10 in a three-dimensional space. Here, the first point and the second point are usually physically different positions. However, the present invention is not limited thereto, and may be the same point. In this case, the physical position of the spatial object collimating means 110 becomes the position of the spatial object 20, and processing for the position is performed. Will be done. The spatial object aiming means 110 must be located at the reference point 10, but other components are not necessarily present together in one position. good.

The meaning of aiming means to direct the direction of the spatial object aiming means 110 in the specific direction. Although no viewfinder or monitor display is necessarily required, means for providing such visual information in accordance with the change in the aiming direction may be further provided. However, although not essential, in order to easily know the direction of orientation of the spatial object aiming means 110, a specific portion, such as an arrow mark or a protrusion, is provided on the outer shape of the spatial object aiming means 110. It is preferable if it is enough.

The physical information broadly means time and space physical information about a three-dimensional space including the reference point 10 and the spatial object 20. However, the physical information refers to the reference point 10 and the Refers to information on the direction and distance of the shortest path connecting the space object 20.

Thus, as a specific example, an observer aboard the Han River cruise ship in operation has a device of the present invention, and then aims at the space object aiming means 110 of the device of the present invention toward the third bridge of the Han River Railway Bridge. One example is the case. In this case, the position of the spatial object aiming means 110 at the moment of aiming is the reference point 10, and the direction and distance between the aiming point 10 and the third bridge pier of the Han River Railway become physical geographical information. .

The spatial object specifying means 130 is a means for identifying the spatial object 20 by mapping the absolute coordinates of the spatial object 20 obtained from the physical geographic information with a numerical map .

The absolute coordinates refer to absolute spatial coordinates specified as numerical values on a three-dimensional map. In contrast, relative coordinates refer to the difference in the coordinates of another point with respect to a point.

The numerical map refers to a map in which three-dimensional geographic information of longitude and latitude and three-dimensional geographic information up to altitude information using an elevation map are numerically implemented and are generally digitized and provided in a database form. . There are various types of numerical maps. For example, not only general numerical maps for spatial objects such as mountains and cities, roads, but also sewers, veins including groundwater, oil fields and veins. The thing which targeted this is mentioned. The positions and ranges of all the spatial objects included in the numerical map are specified by digitized three-dimensional coordinates.

The mapping means finding information about which spatial object is located at the coordinates by comparing the three-dimensional coordinates with the data of the numerical map. This is similar to the general database search technology, so detailed description thereof will be omitted.

Therefore, as a specific example, an observer aboard the Han River cruise ship in operation has the device of the present invention, and aims (aims) the spatial object aiming means 110 of the device of the present invention toward the third bridge of the Hangang Railway Bridge. When the direction and distance are obtained as physical geographic information, if the absolute coordinate of the reference point 10, which is the aimed position, is known, the absolute coordinate of the spatial object spaced apart from the reference point absolute coordinate by the direction and distance is known. By retrieving the absolute coordinates from the numerical map, it can be seen that the spatial object corresponding to the absolute coordinates is the third bridge of the Han River Railway Bridge.

The spatial object processing means 140 is a means for performing a predetermined process (S300) for the specified spatial object 20.

The specified space object 20 is a specific object, for example, such as 'Hangang Steel Bridge No. 3 Pier'. In addition, such specific objects are associated with various information, such as specifications, facility management department, construction company, maintenance history, lighting. The various types of information as described above may be provided in various forms and types of database. The spatial object processing means 140 is a means for accessing various information of the specific spatial object 20 as described above, and performing processing such as searching, updating, modifying, and transmitting.

The kind of processing is sufficient if it is any one process within a predetermined range, such as searching, updating, correcting and transmitting. It is possible to select one of a plurality of processing actions through the input means 152 (general purpose device), or to limit one processing action to one device (dedicated device).

Thus, as a specific example, when the Han River Steel Bridge No. 3 Pier is specified as the spatial object 20 to be processed, for example, the illumination of the spatial object 20 from the information database 158 connected through communication means, for example. The pattern data may be acquired and changed to an illumination pattern that turns on only purple lighting for the next 20 minutes, and then uploaded to the information database 158 (only if the management authority is verified, of course). Alternatively, for example, the historical data of the spatial object 20 may be obtained from the information database 158 embedded in the apparatus of the present invention, and the flood level data of the last 10 years may be read.

Here, the space object aiming means (110) is preferably composed of a direction specific part 112 and a distance specific part (118). Because direction and distance are the most important physical geographic information. Of course, you may further include a component that can obtain other physical geographic information.

The direction specifying unit 112 is a component that specifies a direction in which the spatial object 20 is located with respect to the reference point 10. In three-dimensional space, in particular, the direction or angle with respect to the horizontal plane, that is, the elevation angle, and the direction or angle with respect to the specific direction vertical plane, that is, the azimuth angle, are important. Therefore, it is preferable that the direction specific part 112 consists of the altitude angle specific part 114 and the azimuth angle specific part 116.

That is, the altitude angle specifying unit 114 is a component that specifies an altitude angle in the direction in which the spatial object 20 is located with respect to the reference point 10. In order to specify the altitude angle, there is a method of manually inputting through the input means 152, but it is preferable that the altitude angle is automatically and conveniently inputted to the control means 100 and processed through aiming. In this configuration, for example, the altitude angle particular section 114 is preferably made by a gyro sensor.

In addition, the azimuth angle specifying unit 116 is a component for specifying an azimuth angle in the direction in which the spatial object 20 is located with respect to the reference point 10. In order to specify the azimuth angle, there is also a method of manually inputting through the input means 152, but it is preferable that the azimuth angle is automatically and conveniently inputted to the control means 100 and processed through aiming. As a configuration for example, the azimuth specific portion 116 is preferably made of a compass, in particular an electronic compass.

On the other hand, in the dead-reckoning method for determining the azimuth angle where a GPS signal does not reach in recent tunnels, it is common to use not only an electronic compass but also a gyro sensor, but this expensive gyro sensor is not adopted. In addition, techniques for obtaining a similar effect by other alternative means have been disclosed. For example, in the 'Navigating Navigation System Using GPS and Dual Electronic Compass' (2004 Fall Conference, p. 103, Kim Yang-hwan, Dept. of Electronics Engineering, Pusan National University), two or more compasses are connected to each other. The technique to make it public is disclosed. Therefore, the azimuth specific portion 116 is preferably made by a combination of a plurality of compasses.

On the other hand, the distance specifying unit 118 is a component that specifies the distance from the reference point 10 to the spatial object 20. Even if the direction is determined by the direction specifying unit 112, the distance object needs to be specified because the spatial object 20 cannot be specified if it extends to the infinite origin.

In order to specify the distance, it is also preferable to input manually through the input means 152. If the direction is specified, by inputting the distance manually, it can have a virtual effect like the zoom function of the camera. Therefore, the distance specifying unit 118 is preferably made by a zoom means for inputting a distance value changed according to the operation of the slide switch (zoom switch). However, this is not limited, as soon automatically conveniently distance is measured through the aiming at the same time, and it also desirable to be processed is input to the control means 100, as the configuration for this purpose, for example, the distance specifying unit 118 rangefinder In particular, it is preferably made by a laser rangefinder.

Meanwhile, a process of specifying a spatial object with reference to a numerical map based on the physical geographic information will be described in more detail.

3 is an exemplary flowchart for specifying a spatial object, and FIG. 4 is an exemplary flowchart for determining relative coordinates of a spatial object.

The spatial object specifying means 130, which is hardware for such processing, preferably comprises a spatial object relative coordinate determining unit 120, a spatial object absolute coordinate determining unit 134, and a spatial object specifying unit 138. . Here, these components may be implemented as independent processing modules separated from the space object specifying means 130, respectively.

First, when the physical geographic information, that is, the direction and the distance of the spatial object 20 with respect to the reference point 10, is known, the relative position of the spatial object 20 with respect to the reference point 10, that is, the relative coordinate S210 is known. Can be.

The spatial object relative coordinate determiner 120, which is hardware for such processing, is a component that calculates a relative coordinate of the spatial object 20 with respect to the reference point 10. The spatial object relative coordinate determiner 120 preferably includes a vertical relative coordinate determiner 122 and a horizontal relative coordinate determiner 124. The vertical relative coordinate determiner 122 is a component that calculates a difference between the vertical coordinates of the spatial object 20 with respect to the reference point 10, and the horizontal relative coordinate determiner 124 is the reference point ( 10 is a component for calculating the difference in the horizontal coordinates of the spatial object 20 with respect to.

The principle of determining the relative coordinates of the spatial object 20 with respect to the reference point 10 will be described.

5 is a 3D graph for explaining a principle of determining relative coordinates of a spatial object with respect to a reference point.

If the east (E) is set to the x-axis, the north (N) is the y-axis, and the height direction (H) is the z-axis, a rectangular coordinate system is formed. With the origin of this rectangular coordinate system as the reference point 10, the observer places the spatial object aiming means 110 of the present invention, and is located at the east (E) x and north (N) y from this origin. It is assumed that the spatial object 20 is located at. A case where the point of height z of the space object 20 is aimed at the reference point 10 is considered.

First, consider the case viewed from the side.

6 is a vertical graph for explaining the principle of determining the vertical relative coordinates of a spatial object with respect to a reference point.

The measurement distance r is a known value by the distance special part 118, such as a laser rangefinder. In addition, the altitude angle θ is also known by the altitude angle special section 114 such as a gyro sensor. Therefore, the height difference z of the measurement point with respect to the reference point 10 is

, And the horizontal distance ρ from the reference point 10 to the space object 20 is

It can be seen that.

In this case, the height difference z is smaller than the sum (z1 + z2) of the terrain, for example, the height z2 of the hill, which is higher than the actual height z1 of the spatial object 20 and the height of the reference point 10. The height difference z may be used to verify a matching error of the spatial object 20. The height difference z or the tip height z1 + z2 of the spatial object 20 may be obtained based on the height 0 of the reference point 10, but is based on the geoid z0. It can also be obtained.

As such, since the horizontal distance ρ is known, the range is limited to the spatial object 20 on the two-dimensional horizontal numerical map at the altitude of the reference point 10.

Next, consider the case seen from the plane (from top to bottom).

7 is a horizontal graph for explaining the principle of determining the horizontal relative coordinates of a spatial object with respect to a reference point.

The azimuth angle φ is a known value by the azimuth special portion 116 such as a compass. follow

The east coordinate (x) of the measurement point relative to the reference point 10 is

And the radial coordinate (x) of the measurement point relative to the reference point 10 is

Becomes

Next, if the coordinates of the reference point 10 are known, the absolute coordinates of the spatial object 20 (S220) by considering the coordinates of the reference point and the relative coordinates (x, y, z) of the spatial object 20 together. Can be seen. The spatial object absolute coordinate determination unit 134, which is a hardware configuration for this purpose, determines an absolute coordinate of the spatial object 20 from the absolute coordinate of the reference point 10 and the relative coordinate of the spatial object 20. to be.

However, when the absolute coordinate of the reference point 10 is not known or when the absolute coordinate is changed due to the reference point 10 being moved, the coordinates of the reference point 10 at the moment of aiming are newly renewed. There are times when you need to get it. As a hardware configuration for this, the spatial object absolute coordinate determination unit 134, preferably comprises a reference point coordinate determination unit 132 for determining the absolute coordinate of the reference point (10). For example, as shown in FIG. 5, GPS receiving means for specifying the position of the spatial object aiming means 110 located at the reference point 10 constitutes the reference point coordinate determining unit 132, which is located at three points. The configuration which specifies the absolute coordinate of the said reference point 10 by the information from GPS satellites G1, G2, and G3;

Next, the absolute coordinates of the spatial object 20 are mapped to the numerical map. The spatial object specifying unit 138, which is a hardware configuration for this purpose, is a component that specifies the spatial object 20 by mapping the absolute coordinates of the spatial object to the numerical map 156.

In this case, for mapping, the spatial object absolute coordinate mapping unit 136 connected to the spatial object specifying unit 138 may be separately prepared, and the mapping may be performed by the spatial object absolute coordinate mapping unit 136. good.

As a result, the spatial object 20 is uniquely specified.

Here, the spatial object specifying unit 138 preferably obtains a unique feature identifier (UFID) that is a unique spatial object ID by the mapping. The UFID is an identifier designated to have uniqueness in one GIS numeric map.

Hereinafter, a configuration for improving the processing speed and improving specific convenience of the spatial object 20 will be described.

The numerical map 156 is pre-filtered before the mapping of the constituent spatial object 20, and the spatial object specifying means 130 preferably performs the mapping only on the filtered spatial object 20. To this end, filtering means (not shown) may be further provided.

The filtering means reducing the object of processing based on a predetermined criterion.

For example, some observers may be interested in only toxic bridges among numerous natural, artificial and abstract data. In this case, the information of the school, the mountain and the like is only noise. Therefore, it is possible to designate only the bridge to be matched in advance. Then, after the absolute coordinates of the spatial object 20 are calculated, the information filtered by a filter such as a school or a mountain in the vicinity is not matched, and only a bridge is matched. You can save a lot of time.

On the other hand, as a function widely used in applications such as CAD, there is a so-called 'snap' or 'magnet' function, which does not candidate all the points on the path of the pointing movement, but in a predetermined range of main parts For example, it does not move until the virtual boundary is exceeded, and when the virtual boundary is exceeded, it moves to the next main part. Also in the present invention, by providing such a function, the processing speed of matching can be reduced and the accuracy of matching can be improved.

8 is a view for explaining a snap function for smooth space object pointing when aiming at a space object.

Focus points a ', b', and c 'are set at a portion of the outline of each spatial object 20 aimed at the reference point 10. The focus points a ', b', and c 'refer to points set as if they have a virtual suction force, such as a magnet that sucks when the ferromagnetic material is brought closer.

In the focus points a ', b', and c ', virtual suction force ranges are set in advance. When the target is aimed by the spatial object aiming means 110 within the virtual suction force range and an absolute coordinate included in the range is obtained, the focus points a ', b', and c 'are provided. Aiming is performed so that the same processing as that obtained with the absolute coordinates of the focus points a ', b', and c 'is performed.

Therefore, even if aiming is made at a part spaced apart from the focus points a ', b', and c 'by a preset amount (range), the target point operates as if aiming is made at the focus point, and the preset amount (range) Only when aiming is made at a part spaced apart from the focus points a ', b', and c 'so as to deviate from), the target is operated as if the aim is made by passing to an adjacent focus point. This makes it possible to implement a so-called snap function .

In this case, the spatial object specifying means 130 only needs to perform the mapping on the spatial object 20 aimed at the focus point.

For example, in the case where aiming is made between point a and point a ', it is a point within the range of focus point a', so it is treated as if aiming is made at point a ', so that the space corresponds to the absolute coordinate of point a'. This is done by mapping with the object 20a. On the other hand, when the right boundary of the focus point b 'is the point b, and the left boundary of the focus point c' is the point d, when the aim is made at the point c, it is processed as if the aim is not made, There is no data. As the direction of aiming to this point c is changed and moves to the right beyond the boundary of the point d, the focus point becomes the point c ', so that the mapping of the space object 20c of the point c' is made.

In this way, by implementing the snap function, it is possible to interpolate the mapping candidate search between the spatial objects to be mapped, avoiding continuous mapping and enabling discrete mapping, Mapping can be done quickly and accurately.

On the other hand, by cutting off materials other than the aiming direction, the range of the numerical map can be limited to improve the mapping speed. Various methods are possible, but the method of converting in order of 2D plane grid map, 2D view grid map, and 3D view space object information map is effective.

FIG. 9 is a diagram for describing a 3D view space object information map for smooth space object pointing when aiming at a space object.

First, the numerical map 156 is converted into a 2D planar grid map having a predetermined radius centering on the reference point 10 before mapping. When the numerical map 156 is converted into a 2D planar grid map, the numerical map 156 is limited to information about a planar space of a circle shape having a predetermined radius about the reference point 10.

Of course, most maps are gridded in GIS. The numerical map data is processed to create a grid-grid map of variable size. The resolution (resolution) of the grid map is determined by the variable size of the grid spacing. If this is limited to a predetermined radius, the 2D plane grid map is obtained. This is illustrated in FIG. 9A. The data centered on this 2D planar grid map are absolute coordinates.

Thereafter, in particular, the 2D plane grid map includes only the spatial object 20 within the view azimuth angle within a predetermined range based on the azimuth angle in the direction from the reference point 10 toward the spatial object 20. It is limited to.

That is, in the 2D planar grid map, among the planar spaces having an azimuth angle of 360 ° centered on the reference point 10, the space is limited to only the spatial object 20 within a direction corresponding to the aimed azimuth angle or a predetermined width range of the direction. will be. This is a radial area defined by the angle of the left and right variable sizes with its azimuth as the base line. In this way, it is limited to the information about the fan-shaped planar space which makes the reference point 10 the vertex. This is a 2D view grid map because only information of the direction to be directed, that is, the direction that the observer is observing, is included. This determines the location of the area in real time as the observed azimuth angle of the device changes. This is as shown in Fig. 9B. The data centered on this 2D view grid map are also absolute coordinates.

Thereafter, in particular, the 2D view grid map includes a 3D view including only the spatial object 20 within a predetermined view elevation angle within a predetermined range based on an elevation angle of the direction from the reference point 10 toward the spatial object 20. Converted to a grid map.

That is, in the 2D view grid map, in the plane space of the elevation angle 360 ° centered on the reference point 10, only the spatial object 20 within the direction corresponding to the aimed elevation angle or a predetermined width range of the direction. It is three-dimensional. As is evident in the example of FIG. 6, in the planarized 2D view grid map that is equal to the height of the reference point 10, the hill and the building on the hill will overlap. Therefore, it is necessary to add information about the altitude of the spatial object 20 to map the three-dimensional absolute coordinates of the spatial object 20.

This becomes a radial region defined by the elevation angle as the baseline, and is defined as an angle of variable size up and down, and merges with the horizontal radial region formed in the 2D view map to form a three-dimensional cone. In this way, it is limited to the information about the three-dimensional cone-shaped three-dimensional space whose reference point 10 is a vertex. This is a 3D view grid map because only information of the direction to which the viewer is observing is included.

The location of the region is determined in real time as the observation elevation angle of the device changes. Assuming that this is a vertical cross-sectional view it is conceptually the same shape as (b) of FIG. The data centered on this 3D view grid map are also absolute coordinates.

Next, the 3D view grid map is an ID that is a unique identifier for the spatial object 20 in the three-dimensional space on the viewing angle line corresponding to the azimuth and elevation angle in the direction from the reference point 10 toward the spatial object 20. The information is converted into a 3D view space object information map.

The absolute coordinate of the center position of the space object 20 represents only the position of one point. By the way, the spatial object 20 usually has figure information having a center position and a range and shape in six directions. Therefore, in order to specify the spatial object 20 to which the matched absolute coordinate point belongs, it is necessary to consider such figure information. When the spatial object 20 is specified, representative information accessible to various information connected to the spatial object 20 is required. One example of such representative information is an ID, for example, UFID, which is unique and uniquely set for each spatial object 20.

The 3D view space object information map is conceptually as shown in FIG. The data obtained from the 3D view space object information map may be an ID of the specified space object 20, that is, UFID.

In this case, the space object specifying means 130 preferably performs the mapping only on the space object 20 of the 3D view space object information map. That is, the spatial object 20 can be specified by mapping the absolute coordinates of the spatial object 20 in consideration of the distance specified with respect to the 3D view spatial object information map. ID information, for example, UFID, can be obtained for the specified spatial object 20, so that predetermined processing can be performed on the spatial object 20. FIG.

The extraction condition of the target object including a single or multiple determined by the user is called "user filter". The data contents of the 3D view space object information map can be changed in real time by the user filter.

The data classified and extracted by the user filter condition are hereinafter referred to as "class".

Depending on the application, the target point of the device may move to each data unit of the 3D view space object information map, that is, a data unit belonging to a class, or move independently of it.

If position correction and origin adjustment are performed, this device selects one of the surrounding features belonging to the class, that is, the spatial object, and measures the distance and angle to determine the origin adjustment correction data. The corrected absolute position of the calibrated data measurer is calculated.

One point, two points, and three points can be corrected according to the application, and reference values of the measurement error of the absolute position and azimuth / altitude angle of the observer or the reference point 10 can be obtained.

Now, the ID is obtained by measuring the object and matching the angle and distance from the current position to the object with the 3D view space object information map to obtain the ID of the target belonging to the class or moving it to the data unit belonging to the class. You can get the related information by inquiring to.

Therefore, the spatial object is designated to display the observed result information on the display device or other processing depending on the application. Alternatively, the information database may be updated by inputting additional information in the field about the still / video or the target point at which the target point is photographed.

Hereinafter, the processing of the specified spatial object 20 will be described in detail.

The spatial object processing means 140 preferably performs a process on the information database 158 which stores the information on the respective spatial objects 20.

The information database 158 is additional information added to each spatial object 20 constituting the numerical map 156 and may be attached to the numerical map 156. Alternatively, it may be assumed that the numerical map 156 is provided as a separate database.

The information database 158 may be configured to be pre-built in the storage means of the apparatus of the present invention. Alternatively, when the direction angle, the altitude angle, or the distance of the spatial object 20 is determined, data belonging to the range is automatically downloaded from a server connected by communication from time to time and temporarily stored in the storage means of the apparatus of the present invention. May be

The processing may include inquiry, update, modification, deletion, transmission, etc. of items, and may be configured to verify processing authority when necessary.

Here, the spatial object processing unit 140 preferably includes an information database inquiry unit 142 and an inquiry result output unit 144.

The information database inquiry unit 142 is an element that inquires the information about the specified spatial object 20 from the information database 158. The most basic form of database use is lookup. The identifier of the spatial object 20 specified by the spatial object specifying means 130 is input to the information database 158 to obtain necessary information. Since the technical configuration of the inquiry can be implemented using a known technique, a detailed description thereof will be omitted.

The inquiry result output unit 144 is a component that outputs the inquiry result. The inquiry result may be obtained in a processed form through a preset filter or condition. In this case, the output includes a concept of not only outputting through the output means 154 but also transferring the data to another device through the communication means.

On the other hand, the spatial object processing means 140, it is preferable that the information database query unit 142 and the upload unit .

The information database inquiry unit 142 is an element that inquires the information about the specified spatial object 20 from the information database 158.

The upload unit is a component that updates and uploads data to the information database 158. That is, the user of the apparatus of the present invention can not only passively obtain information from the information database 158, but also correct wrong data, record new activities, change settings, and the like.

For example, when a color pattern for a building color interior lighting is databased, and the controller of the lighting means changes the color by reading the value of this information database, the manager of the lighting means uses the apparatus of the present invention. By aiming the lighting means of the building to access the information database to obtain the color pattern of the illumination, modify it, and upload it again to the information database, it is possible to change the color pattern of the subsequent lighting.

Hereinafter, a case of using the device of the present invention with respect to a specific specific use example, which is only the use example to the last, the present invention is not limited thereto.

FIG. 10 is a diagram for explaining the case where the spatial object is a building as an example of the process for the specified spatial object, and the process is an output of status information about the building.

In the case where the device of the present invention is aimed at a building, only the building is matched if the preset filter is limited to the building. In the case of using the snap function, even if the orientation is changed to an adjacent building, it is treated as being aimed at the adjacent building only when the orientation angle is out of a predetermined range. The processing speed can be increased by limiting the numerical map to the 3D view space object information map. The relative coordinate between the reference point 10 and the building 20 on which the spatial object aiming means 110 is located is determined, and the absolute coordinate of the building 20 is determined in consideration of the absolute coordinate of the reference point 10. The UFID of the building 20 may be obtained by mapping this to the numerical map 156. The embedded or online information database 158 can then be accessed and searched for by the UFID of the building to obtain information. The conditions of the information retrieval can vary depending on the application and the usage rights.

As shown in FIG. 10A, information for real estate transaction of the building may be obtained. The user is, for example, a real estate agent.

As shown in FIG. 10B, general administrative information such as the address, completion, and management of the building can also be obtained. This is the case, for example, when a user is a ward official.

As shown in FIG. 10C, tenant name information of the building may be obtained. This is the case, for example, when a user is an employee of a management office.

FIG. 11 is a diagram for explaining the case where the spatial object is a telegraph pole, and the process is an output of history information on the telegraph pole as an example of the process for the specified spatial object.

In the case where the apparatus of the present invention is aimed at the telephone pole, only the power equipment is matched if the preset filter is limited to the power equipment. In the case of using the snap function, even if the orientation is changed to the adjacent substation, it is treated as being aimed at the neighboring substation only when the orientation angle is out of the predetermined range. The processing speed can be increased by limiting the numerical map to the 3D view space object information map. Then, the relative coordinate between the reference point 10 and the telegraph pole in which the spatial object aiming means 110 is located is determined, and the absolute coordinate of the telegraph pole is determined in consideration of the absolute coordinate of the reference point 10, and the numerical map ( 156 to obtain the UFID of the telegraph line. Thereafter, the built-in or online information database 158 can be accessed and searched by the UFID of the telegraph pole to obtain information. The conditions of the information retrieval can vary depending on the application and the usage rights.

As shown in Fig. 11A, the installation date and inspection history information of the telephone pole can be obtained. For example, the user is an electric power facility inspection team of a utility company and wants to identify when the current problem occurred, the cause and the person in charge by examining the inspection history.

As shown in (b) of FIG. 11, general administrative information related to the specification of the telephone pole specification, voltage, GIS information, and the like may be obtained. This is the case, for example, when the user is the administrative manager of a power company.

As described above, the apparatus of the present invention can be applied to various fields. For example, as a general user, the device can be mounted as an additional device in a PDA to provide a guide function for climbing or traveling, or can be used as a front guide when driving a disabled person. For industrial use, KEPCO telegraph poles and buried items on-site inquiry / recorder (coordinates, video, etc.), on-site management equipment of various utilities (gas / water supply), local cable network site management equipment, real estate guide equipment, survey aids, mail / courier services, etc. It can be used as a field device for postal logistics delivery, a feature recognition and driving guide module of a driving robot, and the like. Or as a public use, it can be used as a site query / recorder, environmental survey query / recorder, digital map survey aid, traffic survey query / recorder for the management of public facilities. In addition, the Ministry of Construction and Transportation, National Research Institute of Korea, Environment Agency, National Geographical Institute, Forestry Research Institute, Resource Research Institute, Rural Development Administration, Transportation Society, Surveying Association, Meteorological Society, etc. develops precision and can be applied to military purposes.

The GPS signal can not be caught is divided into two cases.

If you can't catch GPS signal temporarily in the outdoors, you can use the gyro sensor and compass to predict the moving speed and direction, but you can't receive the GPS signal indoors. The device can be used in a ceiling or as open as possible to find out the current location using the received signal.

As such, the present invention can be configured to operate indoors as well as outdoors. This may be considered by dividing the position of the reference point 10, that is, the space object aiming means 110 and whether the position of the space object 20 is indoor or outdoor.

When the reference point 10 is located outdoors, the reference point coordinate determiner 132 preferably receives a GPS satellite signal outdoors. This is the case where the apparatus of the present invention is located outdoors, receives GPS signals from the GPS satellites G1, G2, and G3, so that the absolute coordinates of the spatial object aiming means 110 can be known.

However, the present invention is not limited thereto, and the reference point 10 may be located indoors. In this case, it is preferable that the reference point coordinate determiner 132 receives a beacon signal in the room.

The beacon generally refers to a signal transmitter capable of positioning by receiving a signal at three points or more in a three-dimensional space indoors or two or more points in a two-dimensional space indoors. This has almost the same principle as positioning by GPS satellites in the outdoors. However, it includes all means for positioning in the room, and is not limited to iGPS or indoor GPS by a specific technology.

When the reference point 10 is located indoors, the GIS absolute coordinates of the outdoor of the structure (for example, the building) forming the indoor space may be specified by GPS in the outdoor. In addition, the three-dimensional position of the beacon in the room is also a fixed value based on the GIS absolute coordinates in the outdoor. Therefore, if the relative position between the position of the beacon and the position of the reference point 10, that is, the position difference, is known, the absolute position of the reference point 10 as well as the absolute position of the beacon in the room as well as the absolute position on the GIS in the outdoor can be known. have.

On the other hand, when the spatial object 20 is located outdoors, the numerical map 156 is preferably an outdoor GIS numerical map. Even when the reference point 10 is located indoors, since the location of the reference point 10 on the outdoor GIS is known, the numerical map 156 may be an outdoor GIS numerical map.

When the spatial object 20 is located indoors, the numerical map 156 is preferably an indoor GIS numerical map. The indoor GIS numerical map is a numerical map of the location, size, and shape information of indoor features, artifacts, exhibits, and furnishings of the interior as a numerical map. It corresponds to the numerical map. When the reference point 10 is located indoors, the positional relationship between the position of the reference point 10 specified by the beacon and the spatial object 20 is easily derived, and when the reference point 10 is located outdoors In addition, since the outdoor location of the reference point 10 can be converted into the corresponding GIS location in the room via the fixed beacon, the numerical map 156 is sufficient as the indoor GIS numerical map.

On the other hand, the present invention can be miniaturized and mounted on other equipment. That is, not only when the apparatus of the present invention is itself an article, but also the apparatus of the present invention is a large quantity. It can be miniaturized according to mass production by production, stabilization of technology, and application of related technologies such as MEMS, and can be provided in a chip or modular form as if a digital camera module is inserted into a mobile phone or a notebook computer.

Therefore, at least one of the space object aiming means 110, the space object specifying means 130, and the space object processing means 140 is preferably mounted on a semiconductor chip or module. In this case, the respective constituent means may be implemented separately from each other, and in this case, data may be received through the communication means.

Although the configuration and operation of the present invention have been described above with reference to preferred embodiments, the present invention is not limited thereto, and modifications, improvements, and changes made within the scope not departing from the scope of the present invention are all interpreted as belonging to the present invention. Should be.

According to the present invention, aiming at a space, military, historic site tourism, and power equipment management to specify a real or virtual space object at the aimed point, access GIS information on the space object, and perform processing such as history. It can be applied to various industrial fields.
