Monitoring system, monitoring method, program, and computer-readable recording medium in which computer program is stored

A monitoring method for monitoring an iron scrap, comprising:

• photographing the iron scrap a plurality of times at different timings including current time;
• inputting a plurality of images obtained by photographing in the photographing into a predetermined learning model to sequentially identify a type and a position of an incompatible object that is a target to be removed from the iron scrap and a probability of being an incompatible object, and inputting a probability of being an incompatible object at the current time identified by the learning model and a probability of being an incompatible object identified by the learning model at timings earlier than the current time into a predetermined function to recalculate a probability of being an incompatible object at the current time;
• and
• outputting each of the type and position of the incompatible object when the probability calculated by the inputting has exceeded a predetermined threshold value.

A monitoring system that is a system for monitoring an iron scrap, comprising:

• a photographing unit that photographs the iron scrap a plurality of times at different viewpoints and at different timings including a certain time;
• an incompatible object identifying unit that inputs a plurality of images obtained by photographing with the photographing unit into a learning model to identify each of a type and a position of an incompatible object that is a target to be removed from the iron scrap and a probability of being an incompatible object, and inputs a probability of a plurality of being incompatible objects obtained by inputting a plurality of images photographed at a plurality of viewpoints and at a plurality of timings including the certain time into the learning model to recalculate a probability of being an incompatible object at the certain time;
• and
• an output unit that outputs each of the type and position of the incompatible object when the probability calculated with the incompatible object identifying unit has exceeded a predetermined threshold value.

A non-transitory computer-readable recording medium having one or more executable instructions stored thereon causing a computer to function as a monitoring system which, when executed by processor circuitry, cause the processor circuitry to perform a monitoring method for monitoring an iron scrap, the method comprising:

• photographing an iron scrap that is monitored a plurality of times at different timings including current time;
• inputting a plurality of images obtained by photographing in the photographing into a predetermined learning model to sequentially identify a type and a position of an incompatible object that is a target to be removed from the iron scrap and a probability of being an incompatible object, and inputting a probability of being an incompatible object at the current time identified by the learning model and a probability of being an incompatible object identified by the learning model at timings earlier than the current time into a predetermined function to recalculate a probability of being an incompatible object at the current time;
• and
• outputting each of the type and position of the incompatible object when the probability calculated by the inputting has exceeded a predetermined threshold value.
