Apparatus and method for automated game ball inspection
View Patent ↗An automated game ball inspection apparatus and system for determining quality of surface treatments applied to the surface of game balls. The inspection system includes an imaging system including a detector for creating and providing an image signal of the ball being inspected to an analyzer. The inspection system also includes an environmental modification device to account for contours on the spherical surface of the ball such that the imaging system can create and analyze still images of the ball. A sorter or reject device, may be provided to act upon the ball based on an output signal from the analyzer.
1. A method of automatically inspecting a surface treatment on a game ball, which comprises the steps of:
applying the surface treatment to the game ball;
passing the game ball through an automated inspection system; and
determining conformance of the surface treatment to a predetermined standard, wherein the predetermined standard comprises a reference image of an acceptable surface treatment.
2. The method of claim 1 , wherein the step of determining conformance further comprises the step of:
generating an analysis signal indicative of whether the surface treatment conforms to the predetermined standard.
3. The method of claim 2 , wherein the step of determining conformance further comprises the step of:
using the analysis signal to perform a further operation on the game ball.
4. The method of claim 3 wherein the step using the analysis signal further comprises the step of:
transferring the game ball for further processing or rejecting the game ball depending on the analysis signal generated.
5. The method of claim 1 , wherein the step of determining conformance further comprises the step of:
using at least one analysis algorithm to determine whether extraneous marks are present on the game ball, wherein the extraneous marks comprise missing characters, ink smudges, ink smears, shadowing, missing sections of print, partial character thickness deviation, complete character thickness deviation, or misaligned characters; and
using the analysis algorithm to transfer the game ball for further processing or reject the game ball depending on the analysis signal generated.
6. The method of claim 1 , wherein the step of applying a surface treatment on a game ball comprises the step of:
applying an agent to the surface of a game ball, wherein the agent is able to be illuminated under non-ambient lighting conditions.
7. The method of claim 6 , wherein the step of passing the game ball through an automated inspection system further comprises the steps of:
illuminating the game ball;
detecting the illuminated agent with a machine vision system; and
comparing the illuminated agent to the predetermined standard with a machine vision engine.
8. The method of claim 7 , wherein the step of illuminating the game ball further comprises the steps of:
providing a light source having a wavelength of about 300 nanometers to about 400 nanometers;
directing the light source at the game ball.
9. A method of automatically inspecting a logo print on a game ball, which comprises the steps of:
applying the logo print to the game ball;
passing the game ball through an automated inspection system; and
determining conformance of the logo print to a predetermined standard.
10. The method of claim 9 , wherein the step of applying a logo print to the game ball further comprises the steps of:
preparing a mixture of at least one ink and at least one agent, wherein the agent illuminates upon application of a light source; and
applying the mixture to at least a portion of the game ball.
11. The method of claim 10 , wherein the step of passing the game ball through an automated inspection system further comprises the steps of:
illuminating the game ball;
detecting the illuminated agent with a machine vision system; and
comparing the illuminated agent to the predetermined standard with a machine vision engine.
12. The method of claim 9 , wherein the step of determining conformance further comprises the steps of:
generating an analysis signal indicative of whether the logo print conforms to the predetermined standard; and
using the analysis signal to transfer the game ball for further processing or reject the game ball depending on the analysis signal generated.
13. The method of claim 9 , wherein the predetermined standard comprises a reference image of an acceptable logo.
14. A method of automatically inspecting a surface treatment on a game ball, which comprises the steps of:
applying the surface treatment to the game ball;
passing the game ball through an automated inspection system; and
determining conformance of the surface treatment to a predetermined standard, wherein the step of determining conformance comprises the steps of:
using at least one analysis algorithm to determine whether extraneous marks are present on the game ball, wherein the extrapeons marks comprise missing characters, ink smudges, ink smears, shadowing, missing sections of print, partial character thickness deviation, complete character thickness deviation, or misaligned characters; and
using the analysis algorithm to transfer the game ball for further processing or reject the game ball depending on the analysis signal generated.
15. The method of claim 14 , wherein the step of determining conformance further comprises the step of:
generating an analysis signal indicative of whether the surface treatment conforms to the predetermined standard.
16. The method of claim 15 , wherein the step of determining conformance further comprises the step of:
using the analysis signal to perform a further operation on the game ball.
17. The method of claim 16 , wherein the step using the analysis signal further comprises the step of:
transferring the game ball for further processing or rejecting the game ball depending on the analysis signal generated.
18. The method of claim 14 , wherein the predetermined standard comprises a reference image of an acceptable surface treatment.
19. The method of claim 14 , wherein the step of applying a surface treatment on a game ball comprises the step of:
applying an agent to the surface of a game ball, wherein the agent is able to be illuminated under non-ambient lighting conditions.
20. The method of claim 19 , wherein the step of passing the game ball through an automated inspection system further comprises the steps of:
illuminating the game ball;
detecting the illuminated agent with a machine vision system; and
comparing the illuminated agent to the predetermined standard with a machine vision engine.
21. The method of claim 20 , wherein the step of illuminating the game ball further comprises the steps of:
providing a light source having a wavelength of about 300 nanometers to about 400 nanometers;
directing the light source at the game ball.
