System, method, and program for detecting abnormality

A system for detecting an abnormality, comprising:

• an airborne imaging device;
• and a computer that is communicatively connected with the airborne imaging device, wherein
• the airborne imaging device has:
• a wide-angle imaging unit that collectively images a plurality of objects to be analyzed that are distributed in a constant large area;
• and
• a detail imaging unit that focuses and images an area smaller than the area that can be imaged by the wide-angle imaging unit, and
• the computer has:
• an abnormality detection unit that detects an abnormality of some of the objects to be analyzed in the constant large area based on a first image taken by the wide-angle imaging unit;
• and
• a switch instruction unit that instructs an unmanned air vehicle to switch from the wide-angle imaging unit to the detail imaging unit to take an image if the abnormality detection unit detects an abnormality,
• wherein the object to be analyzed is laver cultivated in the sea,
• the abnormality detection unit detects that the color of a part of laver in the constant large area is different from that of normal laver based on the first image, and
• the detail imaging unit focuses and images around the laver, the color of which is different from that of normal laver, when the abnormality detection unit detects that the color of a part of laver is different from that of normal laver.

A method for detecting an abnormality, comprising the steps of:

• collectively imaging a plurality of objects to be analyzed that are distributed in a constant large area;
• detecting an abnormality of some of the objects to be analyzed in the constant large area based on a first image taken by the wide-angle imaging unit;
• and
• focusing and imaging around the object to be analyzed in which an abnormality was detected by the abnormality detection unit,
• wherein the object to be analyzed is laver cultivated in the sea,
• detecting the abnormality includes detecting that the color of a part of laver in the constant large area is different from that of normal laver based on the first image, and
• focusing and imaging around the object to be analyzed includes focusing and imaging around the laver, the color of which is different from that of normal laver, when detecting that the color of a part of laver is different from that of normal laver.

A computer program product for use in a system for detecting an abnormality, comprising a non-transitory computer usable medium having a set of instructions physically embodied therein, the set of instructions including computer readable program code, which when executed by the system causes a processor to execute the steps of:

• collectively imaging a plurality of objects to be analyzed that are distributed in a constant large area;
• detecting an abnormality of some of the objects to be analyzed in the constant large area based on a first image taken by the wide-angle imaging unit;
• and
• focusing and imaging around the object to be analyzed in which an abnormality was detected by the abnormality detection unit,.
• wherein the object to be analyzed is laver cultivated in the sea,
• detecting the abnormality includes detecting that the color of a part of laver in the constant large area is different from that of normal laver based on the first image, and
• focusing and imaging around the object to be analyzed includes focusing and imaging around the laver, the color of which is different from that of normal laver, when detecting that the color of a part of laver is different from that of normal laver.
