<Management server function>
FIG. 5 is a block diagram illustrating the functions implemented in the management server 1. In the present embodiment, the management server 1 includes a communication unit 110, a flight mission generation unit 120, a first flight route acquisition unit 130, a flight route division unit 140, a past flight route calling unit 150, and a storage unit 1.
60, a report generation unit 170 is provided. The flight mission generation unit 120 includes a second flight route generation unit 121, a third flight route generation unit 123, a candidate flight route setting unit 125, a route editing unit 127, and a return route generation unit 129. Further, the storage unit 160 includes various databases of the flight route storage unit 162, the flight log storage unit 164, and the interface information storage unit 166. Further, as shown in FIG. 6, the flight route storage unit 162 includes the first flight route storage unit 1621, the second flight route storage unit 1623, and the third flight route storage unit 1625.
The return route storage unit 1627 and the past flight route storage unit 1629 are included.

The communication unit 110 communicates with the user terminals 2 and 3, the flying object 4, and the flying object storage device 5. The communication unit 110 also functions as a reception unit that receives flight requests from the user terminals 2 and 3. The flight request may include any of the flight location, flight purpose, and number of flying objects.

The flight mission generation unit 120 generates a flight mission. Flight missions include at least flight routes. The flight route is generated as a third flight route by the third flight route generation unit 123 with reference to the first flight route storage unit 1621 and the second flight route storage unit 1623. The first flight route will be described later. The second flight route is generated by the second flight route generation unit 121, and is automatically generated by setting the target turning radius, the number of waypoints (WP) during turning, and the like, as shown in FIG. 7, for example. It may be a generated configuration, it may be a configuration that calls a preset route and / or waypoint, or it may manually set a waypoint according to the shape of the object or the route length and working time of the second flight route. You may do so. Although the second flight route is a turning route as a specific example of the present embodiment, the route is not limited to this and may be an arbitrarily generated route.

The third flight route generation unit 123 combines the first flight route and the second flight route, thereby
Generate a third flight route. As one of the specific generation examples, each flight route is composed of a plurality of waypoints (including position coordinate information), and the closest waypoints (position coordinates) of the first flight route and the second flight route. ) Can be used as a connection point to generate a third flight route so as to fly continuously on both flight routes, but the present invention is not limited to this.

When there are a plurality of first flight routes searched or generated, the candidate flight route setting unit 125 generates a third flight route corresponding to each of the first flight routes, so that the plurality of third flight routes can be selected. Each can be selected and set as multiple candidate flight routes. As a more specific example, for example, as shown in FIG. 10, the flight time of each candidate flight route is displayed, and the candidate flight route related information (for example, color information) so that each route can be selected is displayed. Etc.) are set, and the user can select one of the flight routes.

After the third flight route is generated and selected by the user as described above, the route editing unit 127 changes a part of the route to a desired route according to the user's instruction, if necessary. As a result, when the first flight route searched or generated by the method described later does not satisfy all the route conditions, or when you want to create a new flight route based on the third flight route used in the past as described later. Even in (for example, increasing or decreasing the number of objects based on the previous flight result), it is possible to generate a flight route modified by the user as the final flight route.

The return route generation unit 129 generates a return route from the flight end point of the second flight route in the object to the flight start position or the flight end position different from the flight start position, and stores it in the return route storage unit 1627. .. This return route is combined with the first flight route and the second flight route when the third flight route is generated by the third flight route generation unit 123. The return route generation unit 129 does not necessarily have to be provided. For example, the flight start position may be automatically set as the flight end position, or the flight may be acquired from outside the management server 1 as in the first flight route. It may be configured.

The flight route may be, for example, a configuration in which the position where the aircraft is carried by the user is set as the flight start position or the user collects the aircraft at the flight end position without having the flight object storage device 5. Then, based on the information of the flight object storage device 5 managed by the management server 1 (for example, position information, storage state information, storage device information, etc.), the flight object storage device selected as the flight start position or flight end position. The configuration may be generated as a flight route including the position of 5.

The first flight route acquisition unit 130 acquires the first flight route generated outside the management server 1 via the communication unit 110, and stores it in the first flight route storage unit 1621. The first flight route is
For example, it is generated based on a bird's-eye view image (for example, satellite photograph or aerial photograph) taken from a satellite or an air vehicle or a map (for example, a map or a route map) showing the bird's-eye view image on a plane. .. As a more specific example, the first flight route is a movement route (for example, a roadway or a railroad track, etc.) along a path in which an animal including a moving body or a human being can move in a form different from that of the flying body.
It can be a route, a sidewalk, a mountain road, a beast road, etc.). This movement route is, for example, the user terminal 2,
API (Application Programming Interface) on 3
) Or application software, etc., based on the above image or figure, if you specify the flight start position, transit position, position of the object, etc., the location information will be sent directly or via the management server 1 to an external server. Etc. (not shown), it is transmitted via the network NW, searches for a route on which the moving body can move based on the position information, and transmits the result to the management server 1. The management server 1 acquires the route of the search result as the first flight route, and the first flight route storage unit 162.
Can be stored in 1. This eliminates the need to manually set all waypoints for the travel route to the object, reducing work load and work time. Further, since the flight is performed on the movement route, it is possible to acquire not only the information on the object but also the information on the movement route to the object. Therefore, for example, it can be used in various situations such as confirmation of road congestion status to an object, confirmation of route status to an object in the event of a disaster, and search of a mountain road when searching for a victim. The acquired information on the movement route at this time may be a moving image, or may be an image captured at an appropriate number of waypoints automatically generated.

Further, in the above-mentioned specific example, it is possible to reduce the load of the management server 1 by performing a route search outside the management server 1, but if the storage capacity and processing capacity of the management server 1 allow, it is managed. It is also possible to perform a route search within the server 1. Furthermore, in the specific example described above,
The first flight route is a moving route different from that of a flying object or a movement route along a route on which animals including humans can move, but the first flight route is not limited to this, and for example, a route obtained by image recognition (for example,). , Mountain range ridges, fences, roofs, electric wires, etc.), general search methods (eg Dijkstra's algorithm, best-first search, A algorithm, etc.) and AI
It is possible to target all routes that can be searched using such as.

When there are a plurality of objects, the flight route dividing unit 140 sets a flight start position on a first flight route that passes through a first flight route that passes through other objects other than the object that reaches the end of the plurality of objects as a transit point. Divide sequentially for each waypoint from. In line with this, in the third flight route generation unit, each of the divided first flight routes and the second flight route in each of the plurality of objects are sequentially combined from the flight start position to form the third flight. Generate a route.

The past flight route calling unit 150 calls the past flight route as the third flight route with reference to the past flight route storage unit 1629. The third flight route generated in the past is manually or automatically stored in the past flight route storage unit 1629. A part of the past flight route can be changed by the route editorial unit 127 before or after the call.

The interface information storage unit 166 is a display unit (display or the like) of the user terminals 2 and 3.
Stores various control information for display in.

The report generation unit 170 generates report information for transmission to the user terminals 2 and 3 based on the flight log storage unit 164. In the present embodiment, for example, it is acquired by the aircraft 4 on the flight route (on the first flight route and / or on the second flight route) and / or on the return route set in the flight mission. Information (still image, moving image, voice and other information) is stored in the flight log storage unit 164.
