FIG. 3 is a diagram illustrating an example of a flowchart relating to an AR control process performed by each function in the AR providing apparatus 100.
First, in step S5, the measurement unit 40 identifies information (AR position information) indicating the current position of the AR providing apparatus 100 using so-called GPS from orbit information acquired from the satellite via the communication device 15. (taking measurement.
Next, in step S <b> 10, the orientation specifying unit (the orientation information acquisition unit 45 and the orientation information acquisition unit 50) specifies the orientation (azimuth and orientation) of the AR providing device 100. That is, the azimuth information acquisition unit 45 acquires the azimuth information calculated by the azimuth detection device 25. The posture information acquisition unit 50 acquires the posture information calculated by the posture detection device 30.

Next, in step S15, the astronomical information reading unit 60 reads (extracts) the celestial body information included in the AR visual field from the storage device 10 based on the position and orientation of the AR providing apparatus 100 and the current time. .
More specifically, first, the astronomical information reading unit 60 includes internal parameters of the display device 20, AR position information, orientation information acquired by the orientation information acquisition unit 45, and orientation information acquired by the orientation information acquisition unit 50. The range on the horizontal coordinate specified by the azimuth angle and the altitude is specified as the AR field of view.
Next, based on the AR position information and the current time, the astronomical information reading unit 60 converts the information on the position of the celestial body (red longitude, declination) included in the celestial information to the position (azimuth and altitude) in the horizon coordinate system. Convert to information. Then, the astronomical information reading unit 60 determines whether or not the converted position (azimuth and altitude) is included in the AR visual field, and extracts astronomical information of the celestial body at the position (azimuth and altitude) determined to be included. To do.
Next, in step S20, the display control unit 75 performs an extended image display process. Note that the processing from steps S5 to S20 is repeatedly performed when the power of the AR providing apparatus is ON. In addition, when the power of the AR providing device is ON, it is assumed that the video data of the real space captured by the imaging device 35 is acquired by the video acquisition unit 55.

FIG. 4 is a diagram illustrating an example of a flowchart relating to an extended image display process performed by each function in the AR providing apparatus 100.
First, the display control unit 75 reads various display modes from the storage device 10 (step S25).
In the present embodiment, as a display mode, a star attribute display mode capable of determining whether or not to display an image representing a star attribute, a constellation display mode capable of determining whether or not to display an image representing constellation information, Star highlight display mode that can determine whether or not to display an image that emphasizes stars, satellite attribute display mode that can determine whether or not to display an image representing attributes related to satellites, etc. A landscape display mode is provided that can determine whether or not to display an image.
Information (ON / OFF) of each display mode is input via an input device (for example, when a user presses a button provided for each display mode at an arbitrary position (for example, a frame portion) of the AR providing apparatus 100). It is set in advance.

In step S <b> 30, the display control unit 75 determines whether or not the star attribute display mode is ON (whether or not a setting for displaying an image representing an attribute related to a star is set). At this time, if it is determined that the star attribute display mode is ON, the display control unit 75 performs the process of step S35. If it is determined that the star attribute display mode is OFF, the display control unit 75 continues. Then, the process of step S40 is performed.
In step S <b> 35, the display control unit 75 generates an extended image that represents attributes related to stars based on the extracted astronomical information. More specifically, the display control unit 75 reads the name of the star included in the celestial information, the classification of the grade, and the name of the person who found the celestial object, and found the name of the star, the magnitude of the star, and the celestial object. An expanded image representing at least one of the names of the persons is generated. When a plurality of celestial body information is extracted, an extended image is generated corresponding to each celestial body information.
Note that the present invention is not limited to the configuration for generating the extended image for all extracted astronomical information. For example, an extended image may be generated only for stars of a predetermined grade or specified by an observer via an input device. Further, for example, an extended image may be generated only for a star for which a star name is set. FIG. 5A shows an example when the extended image 110 representing the attributes related to stars is displayed.

In step S40, the display control unit 75 determines whether or not the constellation display mode is ON (whether or not a setting for displaying an image representing constellation information is set). At this time, if the display control unit 75 determines that the constellation display mode is ON, it subsequently performs the process of step S45. On the other hand, if it is determined that the constellation display mode is OFF, The process of step S50 is performed.
In step S45, the display control unit 75 generates an extended image representing constellation information based on the extracted astronomical information. More specifically, the display control unit 75 is connected by the position information of the star (starting point) defined as shape information (an example of constellation information) regarding the constellation included in the celestial body information, and the star and the constellation line. The position information of the star (end point) to be read is read out, coordinate conversion and projection conversion are performed, and an extended image representing the constellation line is generated. When a plurality of celestial body information is extracted, an extended image is generated corresponding to each celestial body information. The display control unit 75 may generate an extended image representing the constellation line and the name of the constellation based on the constellation information included in the celestial information (information on the shape of the constellation and information on the constellation name to which the celestial body belongs). Good. FIG. 5B shows an example when the extended image 120 representing constellation information is displayed.

In step S50, the display control unit 75 determines whether or not the star emphasis display mode is ON (whether or not a setting for displaying an image emphasizing a star is set). At this time, if it is determined that the star emphasis display mode is ON, the display control unit 75 performs the process of step S55. If it is determined that the star emphasis display mode is OFF, the display control unit 75 continues. Then, the process of step S60 is performed.
In step S55, the display control unit 75 generates an extended image that emphasizes stars based on the extracted celestial body information. More specifically, the display control unit 75 recognizes the star that is originally visually recognized based on the information on the real vision diameter (an example of the size information) included in the celestial body information and the information on the real vision grade (an example of the grade information). An expanded image that emphasizes the star is generated, which is larger than the size of the star and brighter than the brightness of the star that is originally visually recognized. In addition, when the observer cannot visually recognize the star, that is, when the implementation diameter is “0”, the diameter is identifiable by the observer, and when the implementation class is “0”, the observer is identifiable. An extended image that emphasizes stars is generated as a high grade.
FIG. 5C shows an example when an extended image 130 that emphasizes stars is displayed. According to this configuration, the user can easily check the star even in a bright area such as an urban area or in a time zone where the sky is bright such as a moonlit night.
Here, an example in which the star emphasis display mode is ON / OFF has been described. However, not only the binary setting of ON / OFF but also the degree of emphasis can be adjusted steplessly like a slider bar. Good.

In step S60, the display control unit 75 determines whether or not the artificial satellite attribute display mode is ON (whether or not a setting for displaying an image representing an attribute related to the artificial satellite is set). At this time, if the display control unit 75 determines that the satellite attribute display mode is ON, it subsequently performs the process of step S65, and if it determines that the satellite attribute display mode is OFF. Subsequently, the process of step S70 is performed.
In step S65, the display control unit 75 generates an extended image representing an attribute related to the artificial satellite based on the extracted astronomical information.
More specifically, the display control unit 75 determines whether or not the artificial satellite exists in the AR view based on the position of the artificial satellite measured by the orbit measuring unit 65 and the current time. At this time, when the display control unit 75 determines that an artificial satellite exists in the AR field of view, artificial satellite attribute information (information for representing the artificial satellite, information on the name of the artificial satellite, And an information for representing the orbit of the artificial satellite), an extended image representing the artificial satellite, the name of the artificial satellite, and the orbit of the artificial satellite is generated. On the other hand, when the display control unit 75 determines that there is no artificial satellite in the AR field of view, the display control unit 75 subsequently performs the process of step S70. FIG. 5D shows an example when an extended image 140 representing attributes and the like related to artificial satellites is displayed.
When it is determined that there is no artificial satellite in the AR field of view, it is determined whether or not an artificial satellite is included in the AR field of view within a predetermined time (for example, 5 minutes). May be generated, a message indicating that the artificial satellite is approaching and an extended image representing the orbit of the artificial satellite may be generated.
The satellite attribute information may be stored in advance in the storage device 10 or may be acquired from a server or the like via the communication device 15 and stored in the storage device 10. .

In step S70, the display control unit 75 determines whether or not the landscape display mode is ON (whether or not the setting for displaying the extended image with the landscape in front is set). At this time, if it is determined that the landscape display mode is ON, the display control unit 75 performs the process of step S80. If it is determined that the landscape display mode is OFF, the display control unit 75 continues. The process of step S75 is performed.
In step S <b> 75, the display control unit 75 displays the generated extended image on the display device 20.
More specifically, the display control unit 75 includes information on the position of the celestial body (position in the equatorial coordinate system) included in the celestial body information used when generating the extended image, AR position information, the current time, and the precession. Based on the motion, etc., the coordinates of the celestial body in the virtual coordinate system (display coordinates) are converted by converting the position of the celestial body in the equator coordinate system to the position of the celestial body in the horizon coordinate system and projecting the converted position. calculate.

On the other hand, the coordinate correction unit 70 analyzes the video data acquired by the video acquisition unit 55, and calculates the coordinates of the celestial body included in the AR visual field (coordinates in the virtual coordinate system).
At this time, the coordinate correction unit 70 accumulates the luminance of each pixel of the plurality of image data when it is difficult to specify the celestial object with one image data of the video data (when there is not enough luminance). Subsequently, the coordinate correction unit 70 identifies the astronomical object by dividing the image data (AR visual field) into small regions (small regions) and integrating the luminance for each small region (integrating neighboring pixels). Subsequently, the coordinate correction unit 70 calculates the coordinates of the celestial body (corrected coordinates, which is an example of video coordinates) by assigning coordinates to the center of the small area (or the center of gravity of the accumulated luminance).
Then, the coordinate correction unit 70 displays the reference celestial object, for example, the brightest celestial object (the celestial object with display coordinates can be specified by an absolute grade or the like, and the celestial object with correction coordinates can be specified by brightness or the like). When the display coordinates calculated by the control unit 75 are compared with the correction coordinates and it is determined that there is a difference between the coordinates, the display coordinates are calculated based on the correction coordinates (in other words, the display coordinates and the correction coordinates). to correct. For example, when the display coordinates of the reference celestial body are (x, y), the correction coordinates are (x + 1, y + 1), and it is determined that there is a deviation, the display coordinates of the other celestial bodies are (s, t). Is corrected to (s + 1, t + 1). According to this configuration, it is possible to avoid a situation in which the user feels uncomfortable due to a difference between the display position of the extended image and the actual position of the celestial body due to the influence of the magnetic field or the like.

Here, when the coordinate correction unit 70 determines that the deviation exceeds the specified value (including the case where the celestial body of the video data cannot be specified), that is, partly or by an obstacle such as a building or a cloud. If all the celestial objects are not visible, the display coordinates and the correction coordinates are translated, rotated, etc. for all the celestial bodies, and whether or not the display coordinates and the correction coordinates match (the extended image and the image data are Judgment is made or not. At this time, if it is determined that they do not match, the coordinate correction unit 70 does not perform correction.
Then, the display control unit 75 controls the display device 20 to transmit (makes the celestial body visible), and displays the extended image on the display coordinates (or the corrected display coordinates). According to this configuration, even when some or all of the celestial bodies are not visible due to obstacles such as buildings and clouds, the observer can grasp the invisible celestial bodies. The display control unit 75 may display the generated extended image on the display device 20 by superimposing it on the video data.

In step S80, the display control unit 75 displays the extended image with the landscape in front.
More specifically, the display control unit 75 (coordinate correction unit 70) calculates display coordinates in the same manner as in step S75. Then, the display control unit 75 analyzes the video data acquired by the video acquisition unit 55, specifies a target (landscape such as a building or a cloud) other than a celestial body, and coordinates (landscape coordinates) of the range of the specified target. Is calculated. Then, the display control unit 75 controls transmission of the display device 20 and displays an extended image obtained by removing an image of a portion overlapping with the specified target from the extended image based on the landscape coordinates. FIG. 5E shows an example when the extended image 120 is displayed with the landscape 150 in front.
Here, the video data acquired by the video acquisition unit 55 is analyzed, and the coordinates of the celestial bodies included in the AR visual field (coordinates in the virtual coordinate system) are calculated. For example, three-dimensional map information is stored in the storage device 10. Further, it may be stored and it may be determined whether an obstacle such as a building or a mountain exists in the AR view based on the position / orientation / posture of the AR providing apparatus 100.
