Field of the Invention The present invention relates to a system for supplying dynamically changing information such as weather information to an aircraft or the like in real time, and more particularly to processing weather information or the like using three-dimensional coordinate data and displaying the data in a bird's eye view or the like. The present invention also relates to a three-dimensional information processing system and a three-dimensional information processing method for predicting the influence of weather and the like on operation.

[0002]

2. Description of the Related Art In order to operate an aircraft, it is necessary to carefully check a lot of information such as weather information around the route and routes of other aircraft for safety.

Conventionally, such information is displayed by a control organization for an aircraft pilot or the like as text data in the form of text, or the altitude of each object such as an aircraft is numerically displayed on a display or the like in a plan view from the viewpoint of the sky or the like. Notification was made using the system.

[0004] However, an aircraft sails over a three-dimensional sky, and it is necessary to recognize the positional relationship in a three-dimensional space with respect to such weather information and other information such as the route of other aircraft. is there.

For this reason, there has been a demand for a three-dimensional information processing method and a three-dimensional information processing system for displaying such weather information and the like in a three-dimensional graphic such as a bird's-eye view for easy understanding in more detail than a plan view.

[0006] Conventional techniques for displaying navigation-related information in a three-dimensional graphic are disclosed in Japanese Patent Application Laid-Open No. 03-04160.
0, JP-A-09-091600, JP-A-11-0445
There is a prior art disclosed in US Pat.

In the prior art disclosed in Japanese Patent Application Laid-Open No. 03-041600, there is proposed a technique for displaying the position of another aircraft in a three-dimensional graphic to avoid collision between aircrafts.

In the prior art disclosed in Japanese Patent Application Laid-Open No. 09/091600, the current position of the own device is recognized by using the GPS similarly to the car navigation system, and the terrain and high-rise buildings around the own device are recognized. 2. Description of the Related Art There has been proposed an aircraft navigation system for displaying a two-dimensional graphic.
The prior art disclosed in Japanese Patent Application Laid-Open No. H11-044551 is an aircraft navigation system using GPS, similar to Japanese Patent Application Laid-Open No. 09-091600, which receives position data of other aircraft and displays them in three-dimensional graphics. Sigiji has been proposed.

[0009]

As described above, the conventional three-dimensional information processing method and the conventional three-dimensional information processing system have the following problems.

Heretofore, it has not been possible to supply dynamically changing three-dimensional information such as weather information required for navigation of an aircraft or to display the information in three-dimensional graphics.

The conventional techniques disclosed in the above-mentioned Japanese Patent Application Laid-Open Nos. 03-041600 and 09-091600 are techniques for avoiding collision and for navigation, and cannot handle weather information.

Also, since weather information is information that changes dynamically unlike fixed data such as terrain, the latest detailed three-dimensional position data is required to display it in three-dimensional graphics. Yes, you need to get it. Furthermore, even if such detailed three-dimensional position data is obtained, in order to display the weather information in a three-dimensional graphic, the weather information is intangible information, so solid obstacles such as terrain and high-rise buildings are required. Unlike the display of an object, a display method such as displaying the surface by painting it out cannot be applied as it is. In order to display weather information, processing such as special color classification is required.

However, the prior art disclosed in Japanese Patent Application Laid-Open No. H11-044551 has a function of receiving weather information from a control organization in addition to a function of displaying fixed data such as terrain. There is no function to convert the data of weather information into a three-dimensional graphic based on the three-dimensional positional relationship, without a function for controlling the three-dimensional position data on the side of the control organization or the received aircraft.

In addition, when displaying information related to the navigation of the aircraft as a three-dimensional graphic, in order to pay attention to the influence of weather conditions during navigation, the range of the airspace that affects the operation of the aircraft in accordance with the weather conditions is calculated. Is displayed,
Furthermore, if this airspace is compared with the airspace of bad weather, etc., the effect of weather conditions on the operation is automatically determined, and if the airspace that affects the operation due to this bad weather is displayed in different colors, it will bypass the airspace of bad weather. This will be very useful for making decisions.

However, the conventional three-dimensional information processing method and three-dimensional information processing system do not realize these functions.

In displaying dynamically changing information such as weather information, it is preferable that not only the current state but also past records and future forecasts can be displayed. By sequentially displaying the data at each of these times in chronological order, it is possible to recognize the situation of dynamic changes such as weather information.

However, this function has not been realized in a conventional three-dimensional information processing method or a three-dimensional information processing system that displays information related to the operation of an aircraft in three-dimensional graphics.

In addition, automatic extraction / provision of information required by a specific in-flight aircraft is not performed.

A first object of the present invention is to solve the above-mentioned drawbacks of the prior art, and to provide weather information such as cumulonimbus clouds and bad weather in wind shears around aircraft routes, information on routes of other aircraft, and obstacles on the ground. By expressing all the positional relationships such as the three-dimensional mesh data, extracting the values of these information at each three-dimensional coordinate, and displaying a three-dimensional bird's-eye view together with the topographical numerical data, the user can An object of the present invention is to provide a three-dimensional information processing method and a three-dimensional information processing system for accurately confirming three-dimensional information, selecting an appropriate route, and performing safe operation.

A second object of the present invention is to solve the above-mentioned drawbacks of the prior art, to realize a clear notification of an operation obstacle such as bad weather and the location of the occurrence of the obstacle, and to provide an accurate operation for avoiding this operation obstacle. An object of the present invention is to provide a three-dimensional information processing method and a three-dimensional information processing system for assisting a determination.

A third object of the present invention is to solve the above-mentioned drawbacks of the prior art, and to display and change detailed three-dimensional positional relationship in order to confirm and grasp dynamically changing information such as weather information. To provide a three-dimensional information processing method and a three-dimensional information processing system.

Next, the operation of the present embodiment will be described in detail with reference to the drawings.

FIG. 2 is a flowchart for explaining the processing of three-dimensional information according to the present embodiment.

Referring to FIG. 2, the following five processes are sequentially executed in the process of three-dimensional information according to the present embodiment.

That is, three-dimensional mesh data of the airspace, such as the route of the aircraft 2, which is assumed to have an effect on the aircraft 2 is registered (step 201), weather information and the like are registered in the three-dimensional mesh data (step 202), weather information and the like. To determine the effect of the flight on the flight (step 203) and transmit the three-dimensional mesh data to the three-dimensional information display device 20 (step 20).
4) Display of three-dimensional mesh data (Step 205)
Is performed.

Next, each of these five processes will be described in detail.

Step 201: Register the three-dimensional mesh data of the airspace assuming the influence on the aircraft 2, such as the course of the aircraft 2, FIG. 3 shows the airspace for processing the three-dimensional information according to the first embodiment of the present invention. FIG. 4 is a diagram showing an example of three-dimensional mesh data stored in the storage unit according to the first embodiment of the present invention, and FIG. 5 is a block diagram showing an example of the first embodiment of the present invention.
It is a figure showing an example of an airspace corresponding to each coordinate of three-dimensional mesh data of an embodiment.

First, the three-dimensional information processing apparatus 10 receives and inputs current information such as the current position A (latitude, longitude, altitude) of the aircraft 2.

Next, based on the input current position A of the aircraft 2 and the information on the route and the like recorded in the storage unit 13, the predicted position B (n) after the designated time n minutes is calculated by the arithmetic unit 12. Is calculated.

In calculating the predicted position B (n),
By using the spherical trigonometry, highly accurate data can be calculated.

Further, in response to the result of the predicted position B (n), the calculation unit 12 receives the result of the predicted position B (n) and includes a columnar shape having a radius C centered on the sea route and including the current position A of the aircraft 2 and the predicted position B (n). Is registered in the three-dimensional mesh data as an airspace in which the influence on the aircraft 2 is assumed.

As a result, as shown in the example of FIG.
A cylindrical three-dimensional airspace having a radius C centered on the channel is selected. In the present embodiment, as shown in FIGS. 4 and 5, the coordinates of the three-dimensional mesh data are specified by associating the coordinates with the altitude, latitude, and longitude of the airspace.

Step 202: Registration of weather information and the like in three-dimensional mesh data Next, values of weather information and the like at each coordinate of the three-dimensional mesh data are registered.

The three-dimensional information of the current state of weather information (mainly bad weather information), future forecasts, and information related to the operation of NOTAM and the like is stored in three-dimensional locations (locations where bad weather occurs). It is registered for the coordinates of the mesh data. In the example shown in FIG. 4, the weather information is registered in the form of “level 1”, “level 2”,.

Step 203: Judgment of Influence on Flight Due to Weather Information and the Like Next, information on the airspace assumed to have an effect on aircraft 2 registered in step 201, and weather information and the like in each airspace registered in step 202 To determine the effect on the current flight.

In this embodiment, this determination is made by the operation unit 1
In accordance with 2, it is checked whether or not the coordinates of the cylindrical airspace centered on the route of the aircraft 2 in the three-dimensional mesh data and the coordinates of the airspace such as bad weather, which is expected to adversely affect the operation, overlap. Is determined to have an effect or problem on flight.

The investigation of the overlapping portion by the arithmetic unit 12 is as follows.
Each coordinate of the three-dimensional mesh data is identified by indicating whether the overlapping portion is a non-overlapping portion, and is recorded in the temporary storage file 14 together with the address data indicating the target aircraft 2.

In the example shown in FIG. 3, a columnar solid body indicating the airspace around the navigation route and a spherical solid body indicating the airspace where bad weather has occurred are overlapped. It is required that the aircraft 2 make a detour to the non-overlapping portion.

Step 204: Transmission of Three-Dimensional Mesh Data to Display Device Next, the three-dimensional information processing device 10 transmits three-dimensional mesh data to the three-dimensional information display device 20.

In the present embodiment, three-dimensional mesh data is transmitted from the three-dimensional information processing device 10 in the ground control agency 1 to the three-dimensional information display device 20 in the aircraft 2 above.

In the transmission of the three-dimensional mesh data, not only the method of transmitting the mesh data of all the airspaces near the route of the aircraft 2 but also the change of only the part changed from the previously transmitted three-dimensional mesh data. Data may be transmitted.

Further, three-dimensional mesh data representing the terrain on the ground is recorded in the storage unit 13 and transmitted to the three-dimensional information display device 20 together with the dynamically changing mesh data such as the above-mentioned route and weather. By doing so, it is possible to make it easier for a user such as a pilot to understand the display of the three-dimensional mesh data. This uses the numerical data of the terrain by the Geographical Survey Institute and can be used as semi-fixed mesh data.

In the case of displaying on the aircraft 2 as in the present embodiment, three-dimensional mesh data or the like representing such terrain is displayed on the three-dimensional information display device 2 in the aircraft 2.
By providing 0, the processing efficiency is further improved.

Step 205: Display of three-dimensional mesh data Finally, the three-dimensional information display device 20 displays three-dimensional mesh data.

This is because the transmitted three-dimensional mesh data is color-coded by the display unit 22 into an airspace near the navigation route or an airspace in bad weather, and the location designated by the user through the operation unit 23 is designated. The displayed information is displayed by a three-dimensional graphic.

Further, the overlapping portion of these airspaces may be displayed by further color coding. In this case, the determination of the overlapping portion can be performed by the calculation unit 12 in the three-dimensional information processing apparatus 10 in the same manner as the determination of the overlapping portion in step 203.

The display by the display unit 22 has a function of switching to a plan view display or a bird's-eye view display in which the viewpoint is set to the position of the pilot, so that information necessary for the pilot is simulated in a three-dimensional virtual space. It can be displayed on the screen. Here, in the processing of the three-dimensional information for displaying the bird's-eye view from the viewpoint specified using the three-dimensional mesh data, no special processing is required, and a processing system generally used at present is incorporated. This can be realized by:

As described above, in the three-dimensional information processing system according to the present embodiment, weather information such as cumulonimbus clouds and bad weather in wind shear around the route of the aircraft, information of the route of other aircraft, obstacles on the ground, etc. Can be expressed by three-dimensional mesh data, the values of these information at each three-dimensional coordinate can be extracted, and a three-dimensional bird's-eye view or the like can be displayed together with the topographic numerical data.

Next, a second embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 6 is a block diagram showing a configuration of a three-dimensional information processing system according to the second embodiment of the present invention.

Referring to FIG. 6, the difference between the three-dimensional information processing system of the present embodiment and the first embodiment shown in FIG. 1 is that storage unit 13 in three-dimensional information processing apparatus 10a has
Is provided with a three-dimensional information storage unit 17 relating to operation for storing and referring to three-dimensional information relating to various types of operation, whereby the storage unit 13 in the first embodiment can store the three-dimensional information. More types of information,
By providing the information to the user, the situation of the user can be more grasped.

The three-dimensional operation information storage unit 17 stores information on the airport (name, airfield reference point, etc.), runway information (runway number, runway magnetic direction, runway length, runway end coordinates and elevation). Etc.), VHF NAVAIDS (Radio Navigation Equipment) information (identification ID, frequency, coordinates, altitude, effective use range, etc.), air route information (air route name, configuring WAYP)
OINT, NAVAIDS name, etc.), ILS (instrument landing gear) information (ILS identification ID, frequency, magnetic direction, coordinates,

PROACH: WAIPOINT which constitutes the approach method;
NAVIDS information), spot information (spot number and coordinates of each airport), etc. are stored as three-dimensional mesh data for each three-dimensional coordinate such as information (AIS data) having position information necessary for operation. I have.

The information in the three-dimensional information storage unit 17 relating to this operation is transmitted to the communication unit 16 and the
Transmitted to the dimensional information display device 20a and operated by the user
The information selected in accordance with the operation by 3a is displayed on the display unit 22a by a three-dimensional graphic such as a bird's-eye view.

As in the first embodiment, this displayed three-dimensional graphic is displayed by superimposing a plurality of pieces of information or displaying overlapping parts by color.

Similarly, the processing of the other parts of the present system is the same as that of the first embodiment except that it corresponds to the addition of a new type of information.

The information in the three-dimensional information storage unit 17 relating to the operation is semi-fixedly recorded in advance,
The information is stored by a method suitable for each information, such as updating the new data as needed by the input unit 15a. When storing this information, the data is converted into three-dimensional mesh data by the arithmetic unit 12a and recorded as necessary.

As described above, the information in the three-dimensional information storage unit 17 relating to the operation is information having contents independent of each other, and individual information can be individually selected and displayed in the display. In addition, in each of the other units of the system (the control unit 11a, the operation unit 12a, the input unit 15a, the control unit 21a, the display unit 22a, the operation unit 23a, and the like), substantially the same processing is performed on each piece of information. Therefore, the type of information to be added using the three-dimensional information storage unit 17 relating to the operation need not be limited to the above example, and the required type of information is selected and added by the same method as in the present embodiment. By doing so, it is possible to display by a three-dimensional graphic such as an eye view.

Even if the type of information to be used is added or reduced in this way, the points to be changed in the system are few and easy. Therefore, in the three-dimensional information processing system of the present invention, if necessary, It is possible to sufficiently cope with addition and reduction of information types.

As described above, in the three-dimensional information processing system according to the present embodiment, in addition to the effects of the three-dimensional information processing system according to the first embodiment, it is possible to display more types of operation information. The user can understand the situation in more detail.

When displaying by the three-dimensional information display device 20 installed in the aircraft 2 as in each of the above-described embodiments, a part of the processing performed by the three-dimensional information It is good also as what to do. That is, it uses an arithmetic processing unit which is a part of the device in the aircraft 2, acquires position information of its own aircraft and other aircraft and information of its own flight plan while traveling on the aircraft 2 side, In the aircraft 2 such as the dimensional information display device 20, three-dimensional topographical numerical data by the Geographical Survey Institute or the like is stored.

For example, information from the three-dimensional information processing apparatus 10 is received by a personal computer via a network or the like, and is displayed using a software program for realizing the functions of the three-dimensional information display apparatus 20. It is good. In this case, various data such as topographic map information is stored on the personal computer side in a CD-R.
An embodiment in which these data are displayed together by using an OM or the like can be considered.

Further, there is no need to install the two devices of the three-dimensional information processing device 10 and the three-dimensional information display device 20 constituting the present system in different places, and the three-dimensional information processing device 10 has three-dimensional information.
