An imaging processing device includes an image acquisition module configured to acquire an image obtained by photographing the sky with a camera having a known orientation or slant; a time stamp acquisition module configured to acquire a photographing date and time of the image; a photographing position acquisition module configured to acquire position information of a photographing position of the image; a sun position determination module configured to determine a photographed sun position in the image; a reference sun position acquisition module configured to calculate a reference sun position indicating a sun position determined based on the photographing date and time and the position information; and a camera information identification module configured to determine any one of unknown orientation and slant of the camera based on any one of the known orientation and slant of the camera, the photographed sun position, and the reference sun position.

Information processing system, method, and program

A visibility determination system determines a visibility condition based on an image taken by a camera. The visibility determination system includes: an acquisition part, configured to acquire a first extracted image obtained by extracting an edge of an imaging target in a first image taken by the camera; and a determination part, configured to determine visibility based on the first extracted image and a second extracted image that is obtained by extracting the edge of the imaging target in a second image taken by the camera at a different time from the first image.

Visibility determination system, visibility determination method, and non-transitory computer-readable medium

To provide a cloud observation device capable of reducing calculation cost and predicting sunshine probability by a simple method. A cloud observation device includes an image acquisition module which acquires an image in which a camera photographs the sky, a cloud extraction module which extracts clouds in the image, a sun position determination module which determines a sun position in the image, a sunshine probability calculation area setting module which sets a sunshine probability calculation area having the sun position as a base point in the image, and a sunshine probability calculation module which calculates a sunshine probability after a predetermined time has elapsed based on the sunshine probability calculation area and the extracted clouds.
