Image inspection system and image inspection method
Both improvement of a degree of freedom in selecting the model of the imaging device and improvement in accuracy of the image inspection are achieved by causing an imaging device conformable to a standardization standard to perform multi-stage processing in order. A setting device specifies a combination of values of a plurality of selectors for realizing multi-stage processing set by a user on a user interface, and transmits the values of the selectors and register information to the imaging device. The imaging device stores the values of the selectors in a location indicated by the corresponding register information, and sequentially executes the multi-stage processing specified by the combination of the values of the selectors.
1. An image inspection system that includes an imaging device for an image inspection device which captures an image of an inspection object, and a setting device which is connected to the imaging device via a network, acquires a file in which a setting item of the imaging device and register information indicating a location where a setting value of each setting item is stored are described from an outside, transmits data indicating the setting value of each setting item set by a user and the register information corresponding to each setting item included in the file, to the imaging device, and sets the imaging device,
wherein a plurality of selectors associated with the setting items for setting multi-stage processing to be applied to a captured image and register information indicating a location where a value of each selector is stored are included in the file before the captured image captured by the imaging device is output to the outside,
the setting device is configured to display a user interface, specify a combination of the values of the plurality of selectors for realizing the multi-stage processing set by the user on the user interface, and transmit the values of the plurality of selectors and the register information indicating the location where the plurality of selectors is stored, to the imaging device,
the imaging device is configured to store the values of the plurality of selectors in the location indicated by the corresponding register information, and sequentially execute the multi-stage processing specified by the combination of the values of the selectors,
the multi-stage processing is defined by a parameter set including filter processing for the captured image,
a plurality of parameter sets different from each other is prepared in advance, and
any one of the plurality of selectors is a setting item for selecting any one of the plurality of parameter sets prepared in advance.
2. The image inspection system according to claim 1 , wherein
the imaging device is configured to output an image on which the multi-stage processing is sequentially executed, to the outside.
3. The image inspection system according to claim 1 , wherein
a plurality of pieces of filter processing is included in each of the parameter sets, and
any one of the plurality of selectors is a setting item for selecting filter processing to be applied among the plurality of pieces of filter processing.
4. The image inspection system according to claim 1 , wherein
a plurality of pieces of imaging processing and combination processing of combining a plurality of captured images are included in each of the parameter sets.
5. The image inspection system according to claim 4 , wherein
the plurality of pieces of imaging processing is processing for acquiring three or more images by individually applying illumination in at least three or more different directions, and
the combination processing is processing for generating an image indicating a three-dimensional shape of the inspection object based on a principle of photometric stereo based on the three or more images acquired by the plurality of pieces of imaging processing.
6. An image inspection method of inspecting an inspection object by preparing an imaging device for an image inspection device which captures an image of the inspection object, and a setting device which is connected to the imaging device via a network, acquires a file in which a setting item of the imaging device and register information indicating a location where a setting value of each setting item is stored are described, from an outside, transmits data indicating the setting value of each setting item set by a user and the register information corresponding to each setting item included in the file, to the imaging device, and sets the imaging device, the method comprising:
adding, to the file, a plurality of selectors associated with the setting items for setting multi-stage processing to be applied to the captured image and register information indicating a location where a value of each selector is stored before a captured image captured by the imaging device is output to the outside;
by the setting device,
displaying a user interface,
specifying a combination of the values of the plurality of selectors for realizing the multi-stage processing set by the user on the user interface, and transmitting the values of the plurality of selectors and the register information indicating the location in which the plurality of selectors is stored, to the imaging device; and
by the imaging device,
storing the values of the plurality of selectors in the location indicated by the corresponding register information, and sequentially executing the multi-stage processing specified by the combination of the values of the selectors, and
wherein the multi-stage processing is defined by a parameter set including filter processing for the captured image,
a plurality of parameter sets different from each other is prepared in advance, and
any one of the plurality of selectors is a setting item for selecting any one of the plurality of parameter sets prepared in advance.
