<Functional configuration>
Then, as shown in FIG. 3, the information processing apparatus 400 has an acquisition unit 410, an analysis unit 420, and an estimation unit 430.

The acquisition unit 410 acquires the environment information around the user transmitted from the device 200.

Environmental information can be information about buildings around the user or information about celestial bodies that can be seen by the user. Details will be described later.

Further, the environmental information can be information acquired by various sensors of the device 200.

As an example, the device 200 includes a monocular camera, a stereo camera, an infrared depth sensor, an ultrasonic sensor, a millimeter wave radar sensor, a LiDAR (light detection and ranging), and the like as sensors.

The environmental information includes at least the posture information of the user obtained by the posture sensor of the device 200, in addition to the information acquired by the sensor.

The analysis unit 420 analyzes the environmental information acquired by the acquisition unit 410.

As an example, the analysis unit 420 is at least one from the information acquired from the sensor of the device 200, such as a monocular camera, a stereo camera, an infrared depth sensor, an ultrasonic sensor, a millimeter wave radar sensor, and LiDAR (light detection and ranging). Analyze the shape of the object. The objects referred to here are buildings, signs, roads, trees, people, etc. around the user.

The building mentioned here includes not only the entire building but also the internal walls, pillars, ticket gates, vending machines, and other installations. That is, the environmental information includes not only the environment around the user who is outdoors but also the environment around the user who is indoors or underground.

Then, the analysis unit 420 identifies what the object is from the shape of the object. Specifically, the analysis unit 420 acquires at least information regarding the position. Information regarding the position of such an object may be acquired from a map database stored in advance in a predetermined storage device.

The map database manages the shape of the object and its position information in association with each other. When the object is a building or the like, the shape of the object includes the shape of the entire appearance of the building, the shape of the appearance of a part of the building, the shape of a part of the inside of the building, and the like. In the case of a wall or the like, the shape of the wall when forming a straight line, the shape of the wall when forming a corner or a curve, and the like are included.

Further, the analysis unit 420 analyzes the distance between the user and the object from the information acquired by the sensor.

As described above, as an example, the analysis unit 420 obtains information on the position of the object, the distance between the user and the object, and the posture information of the user by analyzing the environmental information acquired by the acquisition unit 410. be able to.

Then, the estimation unit 430 estimates the position of the user who wears or possesses the device 200 based on the result analyzed by the analysis unit 420.

Specifically, the position of the user is estimated based on the information regarding the position of the object obtained from the analysis unit 420, the distance between the user and the object, and the posture information of the user. Specifically, since the position of the object is specified, the position of the user can be estimated based on the posture information of the user and the distance between the object.

If one object is not specified, the position of the user should be estimated based on the posture information of the user and the distance between the objects by using the positions of other identifiable objects. Can be done.

According to the above configuration, it is possible to provide a technical improvement that solves or alleviates at least a part of the above-mentioned problems of the prior art. According to the above embodiment of the present disclosure, the position of the user can be estimated without using the GPS function.

Note that the transmission of the environmental information from the device 200 to the acquisition unit 410 can be performed at intervals close to real time, or can be performed at a specific timing.

The specific timing is, for example, a timing in which a feature point is included in the environmental information acquired by the sensor of the device 200 or the posture information of the user.

The case where the feature points are included in the environmental information is, for example, when the user is walking in the building and the shape of the object is recognized as a corner (turning corner). Therefore, it is necessary to set such a shape in advance as a feature point.

On the other hand, if the environmental information does not include the feature points, the estimation unit estimates the position assuming that the user is traveling straight ahead.

With such a configuration, the amount of communication can be reduced and the burden of analysis processing can be reduced.

Also, the acquisition of environmental information by the sensor can be performed at a specific timing when the user's posture information includes feature points. The feature point in this case is when the user is recognized as turning a corner. Therefore, it is necessary to set such a shape in advance as a feature point.

Even if there is a discrepancy between the predicted user position and the estimated user position, such an event can be improved by making corrections each time the feature point is passed.

As mentioned above, the environmental information can be information about the buildings around the user.

At this time, the information processing system 100 further has a generation unit 440 as shown in FIG.

The generation unit 440 generates a map around the user based on the result analyzed by the analysis unit 420.

The map around the user is the map database described above. That is, the map database contains at least information about the shape of the building. The information regarding the shape of the building includes the information obtained by analyzing the information acquired from the sensor of the device 200 and the information provided by the manager of the building or the like.

As described above, when one object is not specified and the position of the user is estimated by using the position of another identifiable object, the other object is specified and not specified. The building that should be in the position of one object is identified.

At this time, the information about the shape of the building already included in the map database is different from the information obtained by analyzing the information acquired from the sensor of the device 200.

The case where the information about the shape of the building already contained in the map database is different from the information obtained by analyzing the information acquired from the sensor of the device 200 is, for example, when the building is missing or rebuilt. For example.

In this case, the generation unit 440 can update the map database based on the information acquired from the sensor of the device 200.

Since the information about the shape of the building obtained by analyzing the information acquired from the sensor of the device 200 is useful real-time data provided by the user on the spot, the map database can be realized by such a configuration. You can get closer to the state.

The map database may include information on the location of the building. The information regarding the position of the building includes those obtained by the GPS function included in the device 200 or the user terminal 300, and those provided by the manager of the building and the like.

The map database generated in this way can be used in wearable devices such as smart glasses as three-dimensional map information.

Also, since the GPS function is not essential, not only maps related to buildings on the road but also detailed maps inside buildings and underground maps can be easily generated.

Further, as shown in FIG. 5, the information processing apparatus 400 in the present disclosure connects a plurality of devices of the same type or different types that can be worn or possessed by a plurality of users at different locations, or user terminals of a plurality of users and the Internet. It can be a server device that can be connected via.

At this time, the acquisition unit 410 acquires the environment information around the plurality of users transmitted from the plurality of devices.

The analysis unit 420 analyzes the environment information around the plurality of users acquired by the acquisition unit 410.

The generation unit 440 generates a wide-area map by generating and synthesizing maps around a plurality of users based on the results analyzed by the analysis unit 420.

According to such a configuration, the information processing apparatus 400 collects more information than the information provided by a single user, and it becomes possible to generate a map in a wider area.

The estimation unit 430 and the generation unit 440 can estimate the position of the user and generate a map around the user by using the SLAM (Simultaneous Localization and Mapping) method.

The estimation unit 430 has data that models a point cloud data feature having an image acquired from the device 200 in advance, object information detected from the image, and distance information acquired from the sensor unit described later. The location is estimated from similar features by comparing with the features of any or more of the above obtained from the device.

The learning model may be on either the server or the device 200 side. On the other hand, by sending all images and point cloud data to the server via the network, the network load increases and the response performance drops. By processing the feature amount extraction on the device 200 side, only the data necessary for feature comparison can be transmitted to the server, and the search performance can be improved.

Furthermore, by estimating the approximate position by GPS, the range for searching for features can be narrowed down and the search performance can be improved.

A known technique may be used for self-position estimation and environmental map creation using the SLAM method.

The device 200 has a sensor unit for acquiring environmental information around the user, and the sensor unit acquires the distance to an obstacle around the user two-dimensionally or three-dimensionally as environmental information. can do.

As an example, the sensor unit can be an infrared depth sensor, an ultrasonic sensor, a millimeter wave radar sensor, or a LiDAR (light detection and ranging).

The device 200 has a sensor unit that acquires environmental information around the user, and the sensor unit can acquire an captured image by imaging the surroundings of the user as environmental information.

The sensor unit can be, for example, a monocular camera or a stereo camera.

Further, the information processing apparatus 400 in the present disclosure can further have a guide output unit 450.

The guide output unit 450 outputs a guide for acquiring the information necessary for estimating the user's position to the user's device 200.

As described above, when one object is not specified or necessary information is insufficient, a guide is output to the user's device 200 so that the information of the other object can be acquired. be able to.

For example, if the device 200 is an earphone, a voice guide such as "Look at the building on the right for 〇 seconds" or "Please go forward 〇" can be output from the speaker.

If the device 200 is a smart glass, a character guide such as "Look at the building on the right for 〇 seconds" or "Please go forward 〇" can be output to the display unit.

In addition, the environmental information can be information about celestial bodies that can be visually recognized by the user.

At this time, the analysis unit 420 and the estimation unit 430 analyze the environmental information using the celestial method and estimate the user's position.

Such a celestial method measures the user's position by measuring the angle between the celestial body (sun, moon, planet, star) captured by the camera of the user's device 200 (smart glasses in this case) and the horizon (viewing horizon). Can be estimated. A known technique can be used for estimating the user's position using such a celestial method.

Further, the environmental information may include personal information about people around the user.

At this time, the generation unit 440 generates a map around the user including the person information.

Then, the information processing apparatus 400 is further connected to the information processing apparatus 400 and transmits a map around the user to another user's device associated with the user or the information processing terminal of the other user. It can have a transmitter 460.

The map including person information is, for example, a map in a conference room. Such a map contains information about the existence of a person and the positional relationship with the user.

Such a map can give a user who wears the device 200 and participates in a conference remotely as if he / she is in the conference room and actually participates in the conference.

For example, a seat in the conference room is assigned to the remote-participating user, and the remarks of the participant to the right of the seat can be output from the device 200 of the remote-participating user so as to be heard from the right side. ..
