Item inspecting device
An item inspection apparatus includes an image obtaining section and a control section. The image obtaining section obtains a captured image of at least a part of an item. The control section determines whether the item is defective by using the captured image of the item. The control section performs a first inspection for at least one of position, shape and size with respect to at least one of a first element and a second element. The first element has a predetermined shape and is formed on the item and the second element includes at least one of an opening, a depression and a through-hole formed in the item. The control section performs a second inspection for at least one of foreign substance adhesion, scratch and surface stain on the item. Thus, the defect inspection may be performed more precisely and effectively.
1. An item inspection apparatus comprising:
an image obtaining section obtaining a captured image of at least a part of an item; and
a control section determining whether the item is defective by using the captured image of the item,
wherein the control section performs:
a first inspection for at least one of position, shape and size with respect to at least one of a first element and a second element, wherein the first element has a predetermined shape and is formed on the item and the second element includes at least one of an opening, a depression and a through-hole formed in the item; and
a second inspection for at least one of foreign substance adhesion, scratch and surface stain on the item,
wherein the item has a defined shape of a solid state, and
wherein the control section establishes an area corresponding to at least one of an opening, a depression and a through-hole formed in the item as a masking area and performs only the first inspection of the first inspection and the second inspection for the masking area.
2. The item inspection apparatus of claim 1 , wherein the control section performs the first inspection by comparing the captured image with reference data of the item corresponding to the captured image, based on a feature defined by a shape-based characteristic of at least one of the first element and the second element externally input or automatically extracted.
3. The item inspection apparatus of claim 2 , wherein the feature includes at least one of information on a feature object corresponding to at least one of the first element and the second element and relationship information between a plurality of feature objects.
4. The item inspection apparatus of claim 3 , wherein
the information on the feature object includes at least one of dimension information of the feature object, position information of the feature object, and geometric shape information of the feature object, and
the relationship information between the plurality of feature objects includes at least one of relative distance information between the feature objects, offset information between the feature objects, and geometric shape information between the feature objects.
5. The item inspection apparatus of claim 3 , wherein the control section establishes an inspection area for the feature object, and establishes a good product standard for the feature object.
6. The item inspection apparatus of claim 3 , wherein the control section establishes a correlation between the feature objects and establishes a good product standard for the correlation.
7. The item inspection apparatus of claim 1 , wherein the control section performs the second inspection by comparing the captured image with reference data of the item corresponding to the captured image based on at least one of height, brightness, and color obtained from the captured image of the item.
8. An item inspection apparatus comprising:
an image obtaining section obtaining a captured image of at least a part of an item; and
a control section determining whether the item is defective by using the captured image of the item,
wherein the control section performs:
a first inspection for at least one of position, shape and size with respect to at least one of a first element and a second element, wherein the first element has a predetermined shape and is formed on the item and the second element includes at least one of an opening, a depression and a through-hole formed in the item; and
a second inspection for at least one of foreign substance adhesion, scratch and surface stain on the item,
wherein the item has a defined shape of a solid state, and
wherein the item corresponds to a component of a final finished product, and the control section excludes from the second inspection where the item is shielded from external exposure by assembly with other components.
