Abstract
A system includes a visual sensor provided in an industrial machine or in the vicinity thereof to acquire a plurality of image data, a calculation unit that calculates a contamination degree of a lens or a lens cover of the visual sensor on the basis of the image data acquired by the visual sensor, and a prediction unit that calculates information on a predicted cleaning timing to be performed in the future, of the lens or the lens cover on the basis of the calculated contamination degree of the lens or the lens cover.
Claims20
A visual sensor lens or lens cover abnormality detection system including a visual sensor that is provided in an industrial machine or the vicinity thereof to acquire a plurality of pieces of image data, comprising:
- a calculation unit that calculates a contamination degree of the lens or the lens cover of the visual sensor on the basis of the image data photographed by the visual sensor;
- and
- a prediction unit that calculates information on a predicted cleaning timing to be performed in the future, of the lens or the lens cover on the basis of a plurality of calculations of the contamination degree of the lens or the lens cover calculated by the calculation unit, each of the plurality of calculations being from a respective one of a plurality of images photographed by the visual sensor.
A non-transitory computer-readable medium having a visual sensor lens or lens cover abnormality detection program recorded thereon, the program causing a computer that forms an information processing device of a visual sensor lens or lens cover abnormality detection system including a visual sensor that is provided in an industrial machine or the vicinity thereof to acquire a plurality of pieces of image data to realize:
- a calculation function of calculating a contamination degree of the lens or the lens cover of the visual sensor on the basis of the image data photographed by the visual sensor;
- and
- a prediction function of calculating information on a predicted cleaning timing to be performed in the future, of the lens or the lens cover on the basis of a plurality of calculations of the contamination degree of the lens or the lens cover calculated by the calculation function, each of the plurality of calculations being from a respective one of a plurality of images photographed by the visual sensor.
