Image processing method and data structure of metadata
Provided is an image processing method for image processing on a plurality of captured images obtained by operation of a formation flight. A satellite cluster management device and an image analysis server as image processing apparatuses perform predetermined image processing on the basis of satellite specification information for specifying an artificial satellite associated as metadata with a captured image captured by the artificial satellite.
1. An image processing method, comprising:
receiving, by an image processing apparatus, from an artificial satellite of a plurality of artificial satellites, an image captured by the artificial satellite and metadata associated with the captured image,
wherein the metadata includes:
a satellite cluster identifier that identifies a satellite cluster, wherein the satellite cluster includes the plurality of artificial satellites,
a satellite identifier that identifies the artificial satellite,
first information that indicates a latitude of an imaging target in the captured image and a longitude of the imaging target in the captured image, and
second information that indicates an acceleration of the artificial satellite at a time of the capture of the image; and
performing, by the image processing apparatus, specific image processing on the captured image based on the metadata.
2. The image processing method according to claim 1 , wherein the metadata further includes third information associated with a relative position of each artificial satellite of the plurality of artificial satellites.
3. The image processing method according to claim 2 , wherein the third information includes:
an arrangement sequence of each artificial satellite of the plurality of artificial satellites, and
distances between the plurality of artificial satellites.
4. The image processing method according to claim 1 , further comprising:
receiving, by the image processing apparatus, a plurality of images captured by the plurality of artificial satellites,
wherein the plurality of images includes the image; and
performing, by the image processing apparatus, the specific image processing on the plurality of images based on the metadata.
5. The image processing method according to claim 4 , wherein the specific image processing corresponds to resolution enhancement processing.
6. The image processing method according to claim 4 , wherein the specific image processing corresponds to three-dimensional measurement processing.
7. The image processing method according to claim 4 , wherein
the plurality of images is captured from a same position with a time difference, and
the image processing method further comprises extracting, by the image processing apparatus, a change in an object in the plurality of images.
8. The image processing method according to claim 4 , wherein the plurality of artificial satellites includes a plurality of imaging devices having a same performance.
9. The image processing method according to claim 4 , wherein the plurality of artificial satellites includes a plurality of imaging devices having different performances.
10. A non-transitory computer-readable medium having stored thereon, computer-executable instructions which, when executed by a processor, cause the processor to execute operations, the operations comprising:
receiving, from an artificial satellite of a plurality of artificial satellites, an image captured by the artificial satellite and metadata associated with the captured image,
wherein the metadata includes:
a satellite cluster identifier that identifies a satellite cluster, wherein the satellite cluster includes the plurality of artificial satellites,
a satellite identifier that identifies the artificial satellite,
first information regarding a relative position of each artificial satellite of the plurality of artificial satellites,
second information that indicates a latitude of an imaging target in the captured image and a longitude of the imaging target in the captured image, and
third information that indicates an acceleration of the artificial satellite at a time of the capture of the image; and
performing specific image processing on the captured image based on the metadata.
11. The image processing method according to claim 1 , wherein the specific image processing corresponds to a geometric correction of an orbit position of the artificial satellite.
