Each point (point) A, B, and C within 0 has the same elevation value (10), but may have different values at each point. The information presenting apparatus and method in the present embodiment for providing the viewer with mixed reality in this field 200 will be described below.

FIG. 1 is a block diagram showing the basic arrangement of the information presenting apparatus according to this embodiment.

Reference numeral 108 denotes an input unit composed of an information input device such as a keyboard, which specifies an instruction to start information presentation (presentation start instruction) and an instruction to end information presentation (presentation end instruction), and points. ID (pointer ID) to be used and an ID (observer I) that identifies the observer 105
D) can be entered. Further, when the computerized point ID and observer ID are stored in a readable storage medium, a storage medium reader for reading the computerized point ID and observer ID from this storage medium is added to the input unit 108. Good.

Reference numeral 100 denotes an observer position measuring unit composed of a measuring device such as a GPS or a computer, which measures the position of the observer 105. The measurement of the position of the observer 105 does not need to have sufficient accuracy, and may be any accuracy (rough accuracy) that does not hinder the processing described later. Further, when the input unit 108 is provided, the observer position measuring unit 100 does not necessarily have to be provided.

Further, the observer position measuring unit 100 is constructed by a real space image capturing device such as a CCD camera, and the position of a landmark (an object whose absolute position is known or its characteristic point) of the real space image is detected. The position of the observer may be calculated according to the above, or the position of the observer may be calculated from the degree of similarity between the real space image around the observer and the real space image in which the shooting position is stored in advance. .

Further, the observer position measuring unit 100 is constituted by a signal receiving device, receives a signal emitted by a signal transmitter placed in the physical space, and obtains the position of the observer from the content of the received signal. Good. In addition, any mechanism may be used as long as it is a mechanism for acquiring the position of the observer.

Reference numeral 107 is a viewpoint position database which stores the two tables shown in FIGS. FIG. 3 is a table in which the coordinate values of each point corresponding to each point ID are described, and FIG. 4 is the absolute height of the viewpoint of each observer corresponding to the observer ID of the observer including the observer 105 (FIG. 2 shows a table in which the description in the scale in the coordinate system shown in 2) is described.

Reference numeral 101 denotes an observer position information & viewpoint position information recognition unit, which receives a presentation start instruction from the input unit 108.
The operations of the observer position measuring unit 100, the input unit 108, and each unit except the observer position information & viewpoint position information recognition unit 101 are started. Further, the observer position information & viewpoint position information recognition unit 101 uses the input unit 108 to input the point ID and the observer ID.
Is received and held, and is output to the viewpoint position information extracting unit 102. When the observer ID cannot be received, the default ID is output to the viewpoint position information extracting unit 102 as the observer ID. In this case, the observer position measuring unit 100 may be omitted.

However, the present embodiment is not limited to this,
Besides, for example, the observer position information & viewpoint position information recognition unit 1
01 is the observer 1 input from the observer position measuring unit 100 instead of receiving the presentation start instruction from the input unit 108.
Whether the position of 05 is within a predetermined distance from the point whose coordinates are stored in the viewpoint position database 107, and whether the moving speed of the observer 105 is below a predetermined moving speed for a certain period of time. Judge and observer 105
When the position of is within a predetermined distance from a certain point and the moving speed of the observer 105 is equal to or lower than the predetermined moving speed for a certain period of time (hereinafter, this case will be referred to as “being at a point”), observer position measurement Unit 100, input unit 108,
The operation of each unit except the observer position information & viewpoint position information recognition unit 101 may be started. In this case, the presentation start instruction may not be input from the input unit 108. Similarly, the observer position information & viewpoint position information recognition unit 101 includes the input unit 1
Instead of receiving the point ID from 08, the point ID of the point closest to the viewpoint position of the observer 105 received from the observer position measuring unit 100 is acquired from the viewpoint position database 107 and output to the viewpoint position information extracting unit 102. Good. In this case, the point ID may not be input from the input unit 108.

Reference numeral 102 denotes a point ID and an observer I output from the observer position information & viewpoint position information recognition unit 101.
The viewpoint position database 10 based on the viewpoint position coordinates based on D
The viewpoint position information extraction unit specified from 7 outputs the specified viewpoint position coordinates to the mixed reality space generation unit 103.

Reference numeral 106 denotes a viewpoint azimuth / orientation measuring section for measuring the azimuth / orientation / orientation of the viewpoint of the observer 105, which is constituted by an azimuth / orientation measuring sensor or device (azimuth / orientation measuring device) such as a geomagnetic sensor or a gyro sensor. Since these azimuth and orientation measuring devices cannot be installed at the observer's viewpoint, the outputs of these azimuth and orientation measuring devices do not match the observer's viewpoint azimuth and posture. Therefore, the viewpoint azimuth and orientation detection unit 106
Calculates the viewpoint azimuth and posture of the observer by correcting the output of the azimuth and posture measuring device, and then outputs the result to the mixed reality space generation unit 103.

For example, as shown in FIG. 5, when a gyro sensor as an azimuth / orientation measuring device is fixed to the head of the observer 105, the azimuth / orientation relationship between the azimuth / orientation measuring device 106 and the viewpoint of the observer 105 is kept constant. Since it leans, by applying a fixed conversion formula to the output result of the azimuth and orientation measurement device,
The viewpoint posture of the observer can be calculated. Details of each unit in the figure will be described later.

Further, the viewpoint azimuth / orientation measuring unit 106 is constituted by a physical space image capturing device, and recognizes the position of a landmark (an object whose absolute posture is known or its characteristic point) in the physical space image on the photographed image. Thus, the viewpoint azimuth and orientation of the observer can also be calculated. In addition, any mechanism may be provided as long as it is a mechanism for acquiring the viewpoint azimuth and posture of the observer.

Reference numeral 103 denotes a mixed reality space generation unit for generating an image (MR image) for allowing the observer 105 to experience mixed reality, and the viewpoint position coordinates of the observer 105 from the viewpoint position information extraction unit 102 and the viewpoint. An MR image based on the azimuth and orientation of the viewpoint of the observer 105 from the azimuth and orientation measuring unit 106 is generated. The mixed reality space generation unit 103 is composed of an ordinary computer and outputs the generated MR image to the image display unit 104.

An image display unit 104 presents the MR image input from the mixed reality space generation unit 103 to the observer 105. The image display unit 104 is composed of an image display device such as an HMD or a computer display, and displays the MR image in front of the observer's eyes. To display. As the MR image presentation method, either a video see-through method or an optical see-through method may be used.

Reference numeral 105 is an observer.

A specific flow of presenting an MR image to an observer using the information presenting apparatus of the present embodiment having the above configuration will be described below with reference to the flowchart of the same process shown in FIG. The process of the information presentation device in this embodiment is the process after step S200.

In the following, it is assumed that the observer 105 exists in the field 200 as an example. Each point A,
B and C have a mark such as a foot mark indicating that the position is an available position of the information presenting apparatus according to the present embodiment, and a point ID that specifies this point is explicitly assigned. In step S100, the observer 105 is
Select one of the two points and stand exactly at that location.

As shown in FIG. 5, the observer 105 wears a PC, which is a part of the information presenting device, on his back, and has a wireless keyboard as an input unit 108 in his hand. Also,
GPS is attached as the observer position measuring unit 100,
The observer position measuring unit 100 constantly transmits the position of the observer to the observer position information & viewpoint position information recognizing unit 101. In addition, the observer 105, as shown in FIG.
As shown in FIG. 4, the HMD is mounted on the head, and the viewpoint azimuth and posture meter side part 1
A gyro sensor is attached to the head as 06.

Next, in step S200, the observer 1
05 inputs the point ID of the point where he stands and the observer ID attached to himself to the observer position information & viewpoint position information recognition unit 101 via the input unit 108. In step S200, if the observer ID is not input by the observer, the default ID stored in advance is set as the observer ID.

In step S200, the observer position information & viewpoint position information recognizing unit 101 acquires the position of the observer 105 from the observer position measuring unit 100, and based on this position information, the point at which the observer stands is determined. The point ID may be acquired. That is, the observer 105 can be read from the table shown in FIG.
The point closest to the point is identified, the identified point is determined to be the point where the observer stood, and the point ID
To win.

Next, in step S300, the observer issues a presentation start instruction via the input unit 108 to the observer position information &
It is input to the viewpoint position information recognition unit 101.

In step S300, the observer position information & viewpoint position information recognizing unit 101 acquires the position of the observer 105 from the observer position measuring unit 100, and determines the timing of starting information presentation based on this position information. Then, the presentation start instruction may be generated by the user and input to the user. That is, the point closest to the observer 105 is specified from the table shown in FIG. 3 stored in the viewpoint position database 107, and whether or not the specified point is within a predetermined distance set in advance from the observer 105 is determined. to decide. Further, it is determined whether or not the moving speed of the observer 105 is below a predetermined moving speed for a certain period of time by calculating from the moving distance of the observer 105 within the certain period of time. For example, when the observer 105 is present within a predetermined distance from the point B and at a predetermined speed or less for a certain period of time, the observer position information & viewpoint position information recognition unit 101 says that the observer 105 is at the point B. Judgment, as described above, generate the presentation start instruction,
Type in yourself.

Steps S200 and S300
May be performed first, or both may be performed simultaneously. Further, in step S200, when the observer 105 inputs the point ID and the observer ID, the presentation start instruction may be automatically input simultaneously. Also,
If the input unit 108 is installed at a point where the observer stands, in step S300, the observer 105
When the user inputs the presentation start instruction, the observer position information & viewpoint position information recognition unit 101 can know from which input unit the information is input, for example, by the unique code number of the input unit 108. You may leave it like this. By doing so, the observer 105 only has to connect the input unit to the information presenting device he or she wears and input the observer ID, and the observer position information & viewpoint position information recognition unit 101 can change the input from the input unit 108. The input observer ID is input, and the point at which the input unit 108 is installed is recognized from the unique code number of the input unit 108.

Next, in step S400, the observer position information & viewpoint position information recognizing unit 101 includes the observer position measuring unit 100, the input unit 108, each unit except the observer position information & viewpoint position information recognizing unit 101. The operation of the (starting unit) is started, and the point ID and the observer ID are sent to the viewpoint position information extracting unit 102.

Next, in step S500, the viewpoint position information extraction unit 102 acquires the viewpoint position coordinates of the observer from the viewpoint position database 107 from the input point ID and observer ID. For example, when the observer 105 is at the point A (point A), the coordinate value (100, 10, 15) of the point A is acquired from the table shown in FIG.
Next, referring to the observer ID, the height of the observer's viewpoint is acquired from the viewpoint position database 107 as the viewpoint position coordinates of the observer. For example, when the observer ID is 0002, the height of the viewpoint of this observer can be specified as 180 from FIG. As a result, when the observer whose observer ID is 0002 is at point A, the viewpoint position of this observer is
It is calculated by the coordinate value of the point A + the height of the viewpoint of the observer specified by the observer ID 0002, and the result (100, 1
90, 15). By doing so, the viewpoint position (viewpoint position coordinate) of each observer at each point can be obtained.

Then, in step S600, the viewpoint azimuth / orientation measuring unit 106 measures the viewpoint azimuth / orientation of the observer.

Next, in step S700, the azimuth and orientation of the viewpoint of the observer 105 measured by the viewpoint azimuth and orientation measuring unit 106 in step S600 and the viewpoint position coordinates acquired by the viewpoint position information extracting unit 102 in step S500 are mixed reality space. Send to the generation unit 103.

Next, in step S800, the mixed reality space generation unit 103 generates an MR image to be presented to the observer based on the observer's viewpoint position coordinates and orientation.

Next, in step S900, the HMD as the image display unit 104 outputs an MR image. As a result, the observer 105 can see the MR image based on his / her viewpoint position and azimuth / orientation at the point where he / she is, via the HMD. The method of generating the MR image is not included in the scope of this embodiment, and thus the description thereof is omitted here.

Next, in step S1000, it is confirmed whether or not there is an instruction to end the presentation of information. When the presentation end instruction is confirmed, specifically, when the observer 105 inputs the presentation end instruction to the input unit 108, the observer position measuring unit 1
00, the input unit 108, and the operation of each unit except the observer position information & viewpoint position information recognition unit 101 are stopped, and the process proceeds to step S1100. If the presentation end instruction is not input to the input unit, the process returns to step S600.

In step S1000, it is determined from the measurement result of the observer position measuring unit 100 whether or not the observer 105 is at the same point. If it is determined that the observer 105 is not at the same point, an instruction to end the presentation of information is given. Generate
The operations of the observer position measuring unit 100, the input unit 108, and each unit except the observer position information & viewpoint position information recognizing unit 101 may be stopped, and the process may proceed to step S1100. In this case, when it is determined that they are at the same point, step S600 and subsequent steps are repeatedly executed.

In step S1100, it is confirmed whether the entire system is to be terminated. If not completed, the process returns to step S100.

As described above, according to the information presenting apparatus and method of the present embodiment, when the MR image is generated based on the viewpoint position and the azimuth and posture of the observer at a plurality of points provided in the field in advance, The object to be measured is only the observer's viewpoint azimuth and posture, and the observer's viewpoint position can be specified by the point ID of the point at which the observer is present without measuring. As a result, an MR image in which accurate alignment between the real space and the virtual space is realized can be generated and presented to the observer without preparing a highly accurate viewpoint position measuring device.

Also, outdoors where equipment cannot be installed,
Even if a plurality of points are scattered over a wide range, an MR image in which the real space and the virtual space are accurately aligned can be generated and presented to the observer.

The name of the observer may be used as the observer ID. In that case, the observer ID described in FIG. 4 is changed to the observer's name. Further, either the observer ID or the observer's name may be selectable.

In the present embodiment, the observer ID and the point ID are manually input using the wireless keyboard as the input unit 108. However, the input unit 108 and the input voice are used for voice input. It may be configured with a recognition unit for recognizing. Further, when the observer ID and the point ID are input by a barcode, the input unit 108 may be configured by a barcode reader. In addition, the signal transmitters installed at a plurality of points provided in advance in the field and the signal receiver worn by the observer constitute the input unit 108, and the observer 105 pushes the switch of the signal transmitter to obtain points. The ID may be obtained.

In this embodiment, the point ID and the presentation start instruction (presentation end instruction) are manually input through the input unit 108, but as described above, the observer position measuring unit 1 is used.
00 may be used (hereinafter, non-manual). Further, the point ID and the presentation end instruction (presentation end instruction) may be manually or non-manually input, or a combination thereof.
