JP7706416B2 - Utilization device, utilization method, and utilization program - Google Patents

Description

This disclosure relates to a platform that enables users to use analysis services for images obtained by satellites.

In a system that operates a wide variety of observation satellites to provide users with observation data, when a user requests it, archived data acquired during previous operations or new data acquired during new operations must be processed in response to the request.
The user needs to choose an operator and a satellite. The user needs to choose archive or new observations. The user needs to choose a service. The user needs to consider how to combine them. Since there is no criteria for choosing these (or only partial criteria), there is a possibility that the data suitable for the information required may not be available.
If operators do not have the required satellites, the required archives and the required services, they cannot (or will have to wait long to) act - in other words, there is an opportunity cost.

Patent Document 1 discloses the following technology: The system identifies satellites and orbital paths capable of observing an area requested by a user. The system then uses a combination of these to determine an observation plan for efficiently observing the requested area.

JP 2019-127124 A

Lack of know-how on satellite utilization means users are unable to determine how best to use which satellites. For example, users cannot determine what satellite data they need, how much data they need, how frequently they need data, and whether to archive or use new observations.

The utilization device of the present disclosure is
a request receiving unit that receives a user request indicating a necessary condition for an analysis service of an observation image obtained by observation from an observation satellite;
a satellite candidate search unit that uses a satellite database in which satellite information of each of a plurality of observation satellites is stored to search for one or more observation satellites corresponding to the one or more pieces of satellite information that meet the necessary conditions as one or more observation satellite candidates;

The observation request unit 150 receives new images as follows.
First, the observation request unit 150 transmits an observation request.
An observation request is data for requesting observation by a selected satellite, and indicates the selected satellite, observation time, observation area, etc.
For example, the observation request unit 150 transmits an observation request to an operation system of a business operator that operates the selected satellite. The operation system receives the observation request, causes the selected satellite to perform observation in response to the observation request, receives new images obtained by the performed observation, and transmits the new images to the utilization device 100.
The observation request unit 150 then receives the new image.

However, if the selected combination does not include any observation satellite candidates, step S220 is not executed.

In step S230, the image analysis unit 160 analyzes the new image and the selected image using the selected application.
However, if the selected combination does not include any satellite candidates, analysis of new images is not performed. Also, if the selected combination does not include any archived image candidates, analysis of selected images is not performed.
