Abstract
An image capturing unit captures an image of a surface of a member treated by a surface treatment unit. A comparison unit obtains a correlation coefficient between a reference image stored in a storage unit and the image captured by the image capturing unit. A cross-correlation coefficient between power spectra of the reference image and the image captured by the image capturing unit is obtained. A control unit stops a surface treatment performed by the surface treatment unit when the correlation coefficient obtained by the comparison unit reaches a set value.
Claims20
A surface treatment system comprising:
- a storage configured to store reference images of a surface of a treatment target member, the reference images capturing a plurality of different final target treatment states of the surface of the treatment target member;
- a surface treater configured to perform a surface treatment on the surface of the treatment target member based on a selection instruction received from a user, the selection instruction indicating a selected final target treatment state from the plurality of different final target treatment states;
- an image recorder configured to capture an image of the surface of the treatment target member being treated by the surface treater;
- a comparer configured to obtain a correlation coefficient between the reference image for the selected final target treatment state stored in the storage and the image captured by the image recorder;
- and
- a controller configured to stop the surface treatment performed by the surface treater in response to the correlation coefficient obtained by the comparer reaching a set value.
A surface treatment method comprising:
- storing in a storage reference images of a surface of a treatment target member, the reference images capturing a plurality of different final target treatment states of the surface of the treatment target member;
- performing, by a surface treater, a surface treatment on the surface of the treatment target member based on a selection instruction received from a user, the selection instruction indicating a selected final target treatment state from the plurality of different final target treatment states;
- capturing, by an image recorder, an image of the surface of the treatment target member being treated by the surface treater;
- obtaining, by a comparer, a correlation coefficient between the reference image for the selected final target treatment state stored in the storage and the image captured by the image recorder;
- and
- stopping, by a controller, the surface treatment performed by the surface treater in response to the correlation coefficient obtained by the comparer reaching a set value.
