Abstract
A management device that manages a unit including a drum and a long object wound around the drum, the management device includes: a receiver that receives, from a user terminal, a captured image obtained by capturing an image of the unit; and a controller that accesses correspondence data obtained by associating each of image capture results, obtained by successively capturing images of the unit while winding the long object around the drum, with a corresponding winding amount of the long object wound around the drum at a time when the each of the image capture results was obtained. The controller determines a remaining amount of the long object based on the captured image and the correspondence data.
Claims10
A management method for managing a unit including a drum and a long object wound around the drum, the management method comprising:
- manufacturing the unit by winding the long object around the drum while rotating the drum;
- successively measuring, with a length measuring device, winding amounts of the long object wound around the drum while rotating the drum;
- successively capturing, with a camera, images of the unit while rotating the drum;
- while rotating the drum, successively acquiring, with a controller, the measured winding amounts and the captured images;
- generating, with the controller, a plurality of pieces of registration data each of which associates one of the captured images with a corresponding one of the measured winding amounts;
- generating, with a management device, correspondence data based on the generated plurality of pieces of registration data;
- acquiring, with the management device, an image of the unit captured by a user terminal;
- and
- determining, with the management device, a remaining amount of the long object in the unit by matching the image captured by the user terminal with the captured images in the correspondence data.
A method for generating correspondence data for determining a remaining amount of a long object wound around a drum, the method comprising:
- manufacturing a unit by winding the long object around the drum while rotating the drum;
- successively measuring, with a length measuring device, winding amounts of the long object wound around the drum while rotating the drum;
- successively capturing, with a camera, images of the unit while rotating the drum;
- while rotating the drum, successively acquiring, with a controller, the measured winding amounts and the captured images;
- generating, with the controller, a plurality of pieces of registration data each of which associates one of the captured images with a corresponding one of the measured winding amounts;
- and
- generating, with a management device, the correspondence data based on the generated plurality of pieces of registration data.
A management system that manages a unit including a drum and a long object wound around the drum, the management system comprising:
- a unit manufacturing device that manufactures the unit by winding the long object around the drum while rotating the drum;
- a length measuring device that successively measures winding amounts of the long object wound around the drum while rotating the drum;
- a camera that successively captures images of the unit while rotating the drum;
- a controller that:
- while rotating the drum, successively acquires the measured winding amounts and the captured images,
- generates a plurality of pieces of registration data each of which associates one of the captured images with a corresponding one of the measured winding amounts;
- and
- a management device that:
- generates correspondence data based on the generated plurality of pieces of registration data,
- acquires an image of the unit captured by a user terminal, and
- determines a remaining amount of the long object in the unit by matching the image captured by the user terminal with the captured images in the correspondence data.
