FIG. 3 is a diagram showing an example of an image output from the camera 22. FIG. 3 shows an example of an image of a balcony of an apartment, which is captured by the user operating the camera 22. The image includes the floor 101, which is a candidate landing site for the drone 1, and balcony openings 102A and 102B through which the drone 1 enters the apartment including the floor 101.

The sensor 23 measures the distance to objects around the terminal device 2 and outputs depth information corresponding to the distance. In other words, the depth information of each pixel represents the distance to the target. The sensor 23 is configured by, for example, LIDAR (Light Detection and Ranging, Laser Imaging Detection and Rang).

The speaker 25 outputs sound.

The position specifying unit 26 specifies the position of the terminal device 2. The position specifying unit 26 specifies the position of the terminal device 2 using satellite navigation. For example, the position specifying unit 26 specifies the position of the terminal device 2 based on radio waves received from a plurality of GPS (Global Positioning System) satellites. The location of the terminal device 2 can be specified by latitude and longitude, for example. Satellite navigation uses a global navigation satellite system (GNSS) such as GPS, but the satellite positioning system is not limited to GPS.

The storage unit 27 is a volatile memory element such as SRAM (Static RAM) or DRAM (Dynamic RAM), a non-volatile memory element such as flash memory or EEPROM (Electrically Erasable Programmable Read Only Memory), or a magnetic memory element such as a hard disk. It consists of a storage device, etc. The storage unit 27 stores a computer program 27P executed by the control unit 28. Furthermore, the storage unit 27 stores data obtained when the computer program 27P is executed.

The control unit 28 is composed of a processor such as a CPU (Central Processing Unit), and includes a drone information acquisition unit 30, a spatial information acquisition unit 31, and a functional processing unit realized by executing a computer program 27P.

FIG. 4 is a diagram showing an example of drone information.
The drone information 52D includes drone size (height, width, depth), hovering accuracy (vertical, horizontal), and position accuracy (vertical, horizontal). Hovering accuracy (vertical, horizontal) and positional accuracy (vertical, horizontal) are examples of the flight accuracy of the drone 1. According to the drone information 52D, for example, the sizes of the drone 1 in the height direction, width direction, and depth direction are 300 mm, 500 mm, and 500 mm, respectively. Further, the hovering accuracy of the drone 1 in both the vertical direction and the horizontal direction is ±0.1 m. Furthermore, the positional accuracy of the drone 1 in both the vertical and horizontal directions is ±50 mm. In addition, RTK (Real Time Kinematic) improves the positional accuracy of the drone 1 by correcting the position information of the drone 1 obtained from a satellite positioning system such as GPS based on the corrected position information of a reference station installed on the ground. By using a technique called ``, the positional accuracy of the drone 1 can be improved to within a few centimeters.

The spatial information acquisition unit 31 calculates spatial information including the three-dimensional positions of objects existing around the candidate landing site of the drone 1 based on the depth information output by the sensor 23. The spatial information indicates the three-dimensional position of the object in a coordinate system preset in the terminal device 2 (for example, a right-handed coordinate system with the origin at the center of the lens of the camera 22 and the line of sight direction of the camera 22 as the X axis). Shown in coordinates. For example, the spatial information includes the three-dimensional coordinates of the floor 101, openings 102A and 102B, wall surface 103, window 104, pillar 105, and fence 106 in FIG. Note that since the openings 102A and 102B are spaces, the three-dimensional coordinates of the openings 102A and 102B are the coordinates of a point at infinity or an indefinite value.

The entry opening determination unit 32 determines an opening through which the drone 1 can enter the apartment including the floor 101 based on the drone information 52D acquired by the drone information acquisition unit 30 and the spatial information acquired by the spatial information acquisition unit 31. A certain approachable opening and an inaccessible opening, which is an opening through which the drone 1 cannot enter the apartment including the floor 101, are determined.

For example, the entrance opening determining unit 32 determines the horizontal and vertical sizes of each of the openings 102A and 102B shown in FIG. 3 based on the spatial information. The approach opening determining unit 32 determines the size of the area that the drone 1 may occupy from the size, hovering accuracy, and positional accuracy of the drone 1 based on the drone information 52D. In the example shown in FIG. 4, the approach opening determining unit 32 has a height-wise size of 450 mm (=300 mm+0.1 m+50 mm) and a width-wise size of the area that the drone 1 may occupy. 500mm+0.1m+50mm). The approach opening determining unit 32 determines that for each of the openings 102A and 102B, the horizontal size of the opening is 650 mm or less in the width direction that the drone 1 may occupy, and the vertical size of the opening is 650 mm or less. If the size of the opening is 450 mm or less in the height direction that the drone 1 may occupy, the opening is determined to be an accessible opening; otherwise, the opening is determined to be an impossible opening. For example, the entrance opening determining unit 32 determines the opening 102A to be an accessible opening, and determines the opening 102B to be an impossible opening.

The entry opening determining unit 32 determines the entry opening selected by the user among the determined entry openings as the entry opening into which the drone 1 will enter. The entrance opening determining section 32 transmits opening information regarding the determined entrance opening to the server 5 via the communication section 21 .

FIG. 5 is a diagram illustrating an example of aperture information.
The opening information includes opening coordinates (latitude), opening coordinates (longitude), opening height, and opening approach direction. The opening coordinates (latitude) indicate the latitude of the entrance opening, and are, for example, "YY.YYYYYY" (degrees). The opening coordinates (longitude) indicate the longitude of the entrance opening, and are, for example, "XXX.XXXXXX" (degrees). The opening height indicates the height of the entrance opening, and is, for example, "15 m". The opening entry direction indicates the direction of the entry opening with respect to the terminal device 2, and is, for example, "275 degrees." Here, true north is 0 degrees.

Here, the entrance opening determination unit 32 determines the opening coordinates ( (latitude) and opening coordinates (longitude). However, if the three-dimensional position of the approach opening indicates the coordinates of an infinite point or is undefined, the approach opening determining unit 32 determines whether the approach opening has an object around the approach opening (as shown in FIG. 3). In the example, the three-dimensional position of the entrance opening may be calculated from the three-dimensional coordinates of the pillar 105 and the fence 106). For example, when the entrance opening is the opening 102A, the entrance opening determination unit 32 may calculate a three-dimensional position obtained by extending the surface of the fence 106 upward as the three-dimensional position of the opening 102A. . Then, the approach opening determining unit 32 calculates the opening coordinates (latitude) and the opening coordinates (longitude).

The landing site determination unit 33 determines a possible landing site where the drone 1 can land based on the drone information 52D acquired by the drone information acquisition unit 30 and the spatial information acquired by the spatial information acquisition unit 31. The landing site determining unit 33 determines the possible landing site selected by the user among the determined possible landing sites as the landing site of the drone 1.

The movement route determining unit 34 is based on the spatial information calculated by the spatial information acquiring unit 31, the information on the approach opening determined by the approach opening determining unit 32, and the information on the landing site determined by the landing site determining unit 33. Then, the travel route of the drone 1 from the approach opening to the landing site is determined. For example, when the drone 1 enters the inside of the balcony from the entrance opening at a predetermined elevation angle and the drone 1 reaches directly above the landing site, the movement route determining unit 34 changes the course of the drone 1 vertically and lands. Determine the travel route to land at the location. The moving route determining unit 34 transmits the determined moving route information to the server 5 via the communication unit 21. Note that if there is an obstacle or the like between the approach opening and the landing point and the drone 1 cannot move, the movement route determination unit 34 does not determine the movement route and cannot determine the movement route. information indicating this is transmitted to the server 5 via the communication unit 21.

FIG. 6 is a diagram showing an example of travel route information.
The travel route information includes travel route coordinates (1) to (n), landing point coordinates, and reference coordinate orientation. Movement route coordinates (1) to (n) are the coordinates of n points that the drone 1 passes between the approach opening and the landing site. The landing point coordinates are the coordinates of the point where the drone 1 lands. For example, when considering a right-handed coordinate system in which the origin is the lens center of the camera 22 and the X axis is the line of sight direction of the camera 22, the drone 1 has coordinates (X1, Y1, Z1), ..., coordinates (Xn , Yn, Zn) and land at the coordinates (ZL, YL, ZL). The reference coordinate orientation indicates the orientation in the X-axis direction in the coordinate system, and is, for example, "0 degree". Here, true north is 0 degrees.

The accessible opening display unit 35 displays on the touch panel 24 the accessible openings and non-accessible openings determined by the accessible opening determining unit 32 in a distinguishable manner. For example, the accessible opening display section 35 may display accessible openings and non-accessible openings with frames of different colors superimposed on the image taken by the camera 22, or may display accessible openings and non-accessible openings with frames of different colors. The inaccessible opening may be displayed in a different frame.

A frame 111 is a frame that highlights the opening 102A, and a frame 112 is a frame that highlights the opening 102B. The frame 111 is not marked with a cross, which indicates that the opening 102A is an enterable opening. On the other hand, the frame 112 is marked with a cross, indicating that the opening 102B is an inaccessible opening.

The selection information acquisition unit 36 acquires information on the accessible opening selected by the user from among the accessible openings displayed on the touch panel 24 by the accessible opening display unit 35. Specifically, the selection information acquisition unit 36 acquires information on the position touched by the user on the screen from the touch panel 24, and based on the acquired position information and the display position of the accessible opening on the screen, Identifying the user-selected access opening. In the example shown in FIG. 7, the only accessible opening is the opening 102A, so the user selects the opening 102A.

The possible landing site display section 37 displays the possible landing site determined by the landing site determining section 33 on the touch panel 24. For example, the possible landing spot display section 37 may display an area including a possible landing spot superimposed on the image taken by the camera 22 in a different color from other areas.

Furthermore, the possible landing spot display section 37 displays the outline of the drone 1 on the touch panel 24 based on the drone information 52D. For example, the possible landing spot display section 37 displays a rectangular area that the drone 1 may occupy as the outline of the drone 1 based on the size, hovering accuracy, and positional accuracy of the drone 1. In the example shown in FIG. 4, the possible landing spot display section 37 has a rectangle of 450 mm (=300 mm + 0.1 m + 50 mm) in the height direction, 650 mm (500 mm + 0.1 m + 50 mm) in the width direction, and 650 mm (500 mm + 0.1 m + 50 mm) in the depth direction. indicate.

The surface 121 is a surface that includes a possible landing site for the drone 1, and is, for example, a blue surface. The rectangular frame 131 three-dimensionally indicates an area that the drone 1 may occupy.

The selection information acquisition unit 36 further acquires information on the possible landing site selected by the user from among the possible landing sites displayed on the touch panel 24 by the landing site determining unit 33. Specifically, in the example of FIG. 8, the user drags the rectangular frame 131 on the touch panel 24 and releases (drops) his or her finger at the desired position for the drone 1 to land. Note that movement of the rectangular frame 131 by dragging is restricted so that the rectangular frame 131 can be moved only within the plane 121 that includes the possible landing site. The selection information acquisition unit 36 acquires information on the position where the user has dropped from the touch panel 24, and identifies the possible landing site selected by the user based on the acquired positional information and the display position of the possible landing site on the screen. do.

[Processing procedure of delivery system 10]
FIG. 12 is a sequence diagram showing the processing procedure of the delivery system 10 according to the first embodiment of the present disclosure.
The server 5 transmits drone information 52D as shown in FIG. 4 to the terminal device 2, and the terminal device 2 receives the drone information 52D (step S1).

The camera 22 of the terminal device 2 captures an image of the balcony including the candidate landing site for the drone 1 as shown in FIG. 3 (step S2). Note that if the area including the landing candidate site does not fit within the photographing area of the camera 22, the user may pan the camera 22 to photograph a panoramic image wider than the photographing area.

Furthermore, at the same time as the image is captured, the terminal device 2 also captures the objects on the balcony shown in FIG. The distance is measured and depth information is output (step S3).

Based on the depth information, the terminal device 2 calculates spatial information around the candidate landing site, including the three-dimensional positions of objects existing around the candidate landing site (step S4).

Based on the drone information 52D and the spatial information, the terminal device 2 identifies an entry-allowed opening that the drone 1 can enter and an entry-impossible opening that the drone 1 cannot enter. Determine (step S5).

The terminal device 2 causes the touch panel 24 to display an image as shown in FIG. 7 (step S6). Thereby, the opening 102A, which is an accessible opening, and the opening 102B, which is an inaccessible opening, can be distinguished and displayed. Note that the terminal device 2 displays a message "Please specify the drone entrance" superimposed on the image.

The user selects, on the touch panel 24, the opening into which the drone 1 can enter, and the terminal device 2 acquires information on the selected opening (step S7). For example, when the user selects the opening 102A on the image shown in FIG. 7, information on the opening 102A (eg, position information on the image of the opening 102A) is acquired.

The terminal device 2 determines the entry possible opening selected by the user as the entry opening into which the drone 1 will enter (step S8). For example, the terminal device 2 determines the selected opening 102A as the entry opening.

The terminal device 2 determines a landing spot where the drone 1 can land based on the drone information 52D and the spatial information (step S9).

As shown in FIG. 8, the terminal device 2 causes the touch panel 24 to display an image including a surface 121 including a possible landing site for the drone 1 and a rectangular frame 131 indicating an area that the drone 1 may occupy ( Step S10). Note that the terminal device 2 displays a message "Please specify the landing site" superimposed on the image.

The user selects a landing spot for the drone 1 by dragging and dropping the rectangular frame 131 on the touch panel 24, and the terminal device 2 specifies the selected landing spot for the drone 1 (step S11). For example, the rectangular frame 13 shown in FIG.
When the user drops the rectangular frame 131 at position 1, the position in real space corresponding to the position of the rectangular frame 131 on the image is specified as a possible landing spot.

The terminal device 2 determines the possible landing site selected by the user and identified by the terminal device 2 as the landing site for the drone 1 (step S12).

The terminal device 2 displays an image on the touch panel 24 that shows that the drone 1 is calculating the movement route as shown in FIG. 9 (step S13).

The terminal device 2 determines the movement route of the drone 1 from the approach opening to the landing site based on the spatial information, the approach opening information, and the landing site information. The terminal device 2 displays an image showing the movement route 141 of the drone 1 as shown in FIG. 10 on the touch panel 24 (step S14). Note that if the moving route is not found, the terminal device 2 causes the touch panel 24 to display an image indicating that the moving route is not found, and cancels the subsequent processing.

The terminal device 2 transmits opening information (FIG. 5) indicating the position of the determined entrance opening and moving route information (FIG. 6) indicating the determined moving route to the server 5. Information and travel route information are received (step S15).

The server 5 determines the travel route of the drone 1 from the package delivery base to the opening based on the opening information. Furthermore, the server 5 determines a travel route from the delivery base to the landing point through the opening, based on the determined travel route and the travel route information received from the terminal device 2 (step S16).

The server 5 transmits travel route information indicating the travel route from the delivery base to the landing point to the drone 1, and the drone 1 receives the travel route information (step S17).

The drone 1 delivers the package to the landing site by flying from the package delivery base through the opening to the landing site according to the received movement route information (step S18).

If the drone 1 cannot deliver the cargo due to obstacles or the like during flight, it returns to the base and sends error information including information on the point to which it returned to the server 5. The server 5 receives the error information transmitted from the drone 1 (step S19).

Based on the received error information, the server 5 determines that if the drone 1 returns at a point between the opening and the landing site, there is an obstacle on the travel path of the drone 1 and the drone 1 returns to the landing site. Error information indicating that landing was not possible is transmitted to the terminal device 2, and the terminal device 2 receives the error information (step S20).

Based on the error information, the terminal device 2 notifies the user that the drone 1 was unable to land at the landing site due to the presence of an obstacle on the travel route of the drone 1 (step S21).

Therefore, by acquiring the drone information 52D and the spatial information, the terminal device 2 can determine the entry opening through which the drone 1 enters the space around the candidate landing site of the drone 1. Furthermore, the terminal device 2 can also determine the landing site of the drone 1. Once the approach opening and landing site are determined, the terminal device 2 can determine the movement route of the drone 1 from the base to the approach opening and the movement path of the drone 1 from the approach opening to the landing site. . For example, the user acquires spatial information using a distance sensor included in the terminal device 2 such as a smartphone, and the terminal device 2 acquires the drone information 52D from the external server 5, thereby allowing the user to acquire the drone 1 using a simple method. The travel route or landing point of the aircraft can be determined.

Even if the size of the opening is larger than the size of the drone 1, if the hovering accuracy or positioning accuracy of the drone 1 is poor, the drone 1 may come into contact with the area around the opening and enter the opening. It may not be possible. Similarly, even if the size of the landing site is larger than the size of the drone 1, the drone 1 may come into contact with the surroundings of the landing site and be unable to land at the landing site. In the first embodiment, the approach opening and the landing site can be determined in consideration of the hovering accuracy and positional accuracy of the drone 1. Therefore, it is possible to determine an entry opening into which the drone 1 can reliably enter and a landing site into which the drone 1 can reliably land.

Furthermore, the user can select any one of the plurality of accessible openings. As a result, the user can select an accessible opening by excluding an accessible opening that the user does not want the drone 1 to enter, or select an accessible opening that the drone 1 can easily enter. The entrance opening can be determined according to the wishes of the user.

Additionally, inaccessible openings into which the drone 1 cannot enter, such as when the size of the opening is smaller than the size of the drone 1, can be displayed separately from accessible openings. This allows the user to efficiently select an accessible opening.

Additionally, the user can select one of the possible landing sites. As a result, it is possible to select a possible landing site by excluding possible landing sites that the user does not want Drone 1 to land on, or to select a possible landing site where Drone 1 is likely to land easily, so that the landing site can be selected according to the user's wishes. A landing site can be determined.

Further, as shown in FIG. 8, a rectangular frame 131 indicating an area that the drone 1 may occupy is displayed on the touch panel 24. Thereby, the user can select a possible landing site in consideration of the external shape of the drone 1. Therefore, it is possible to reliably determine a landing site where the drone 1 can land.

Furthermore, as shown in FIG. 10, the movement route 141 of the drone 1 from the approach opening to the landing site can be displayed. Therefore, the user can be made aware of the moving route of the drone 1, and the user can be warned not to place anything on the moving route.

Further, if the terminal device 2 cannot determine the movement route of the drone 1 from the approach opening to the landing site, it notifies the user to that effect. This allows the user to take measures such as changing the landing site.

Additionally, the terminal device 2 notifies the user if the drone 1 cannot fly the travel route from the approach opening to the landing site. This allows the user to take measures such as removing obstacles on the travel route or changing the landing site.

The server 5 also acquires the position information of the approach opening determined based on the drone information 52D and the movement route of the drone 1 from the opening to the landing site from the terminal device 2, Determine the route of travel. The server 5 can transmit a movement instruction to the drone 1 based on the determined movement route. Thereby, the drone 1 can be controlled based on the movement route or landing point of the drone 1 determined by a simple method.
