Method, device, system, and computer program for detecting wheel fastener looseness and computer-readable medium storing computer program
An information device including a capturing function uses the capturing function to capture an image of a disc wheel to which a plurality of wheel fasteners are fastened. Then, the information device inspects whether any of the wheel fasteners appearing in the captured image is loose by comparing the captured image with a reference image in consideration of a reference point of the disc wheel appearing in the captured image.
1. A method for detecting wheel fastener looseness, the method comprising the steps of:
causing an information device including a capturing function to use the capturing function to capture an image of a disc wheel to which a plurality of wheel fasteners are fastened; and
causing the information device to inspect whether any one of the wheel fasteners appearing in the captured image is loose by comparing the captured image with a reference image in consideration of a reference point of the disc wheel appearing in the captured image.
2. The method for detecting wheel fastener looseness according to claim 1 ,
wherein the information device further includes a display function,
the method further comprising the step of causing the information device to use the display function to display an inspection result regarding whether any of the wheel fasteners is loose.
3. The method for detecting wheel fastener looseness according to claim 1 , wherein the step of causing the information device to inspect whether any of the wheel fasteners is loose includes causing the information device to correct a tilt of the captured image based on a contour of a wheel disc appearing in the captured image.
4. The method for detecting wheel fastener looseness according to claim 1 , wherein the step of causing the information device to inspect whether any of the wheel fasteners is loose includes causing the information device to correct a magnification of the captured image based on a contour of a wheel disc appearing in the captured image.
5. The method for detecting wheel fastener looseness according to claim 1 , wherein the step of causing the information device to inspect whether any of the wheel fasteners is loose includes causing the information device to correct a rotation angle of the captured image based on the reference point appearing in the captured image.
6. The method for detecting wheel fastener looseness according to claim 1 , wherein the reference point is a position at which an air valve is attached.
7. The method for detecting wheel fastener looseness according to claim 1 , wherein the wheel fasteners are wheel nuts or wheel bolts.
8. A device for detecting wheel fastener looseness configured to perform the steps according to claim 1 .
9. A non-transitory computer-readable medium carrying a computer program comprising a program code which, when executed on a computer, causes the computer to perform the steps according to claim 1 .
10. The method for detecting wheel fastener looseness according to claim 1 , wherein the reference image is an image of the disc wheel to which the plurality of wheel fasteners is fastened.
11. A method for detecting wheel fastener looseness, the method comprising the steps of:
causing an information device including a capturing function to use the capturing unction to capture an image of a disc wheel to which a plurality of wheel fasteners are fastened; and
causing the information device to inspect whether any one of the wheel fasteners appearing in the captured image is loose by comparing the captured image with a reference image in consideration of a reference point of the disc wheel appearing in the captured image, wherein the reference point is a position at which an air valve is attached.
12. A method for detecting wheel fastener looseness, the method comprising the steps of:
causing an information device including a capturing function to use the capturing function to capture an image of a disc wheel to which a plurality of wheel fasteners are fastened, the disc wheel comprising a cylindrical rim to which an inner peripheral edge of a tire is assembled, and a disc shaped wheel disc joined to the inner peripheral surface of the rim; and
causing the information device to inspect whether any one of the wheel fasteners appearing in the captured image is loose by comparing the captured image with a reference image in consideration of a reference point of the disc wheel appearing in the captured image.
13. The method for detecting wheel fastener looseness according to claim 12 , wherein the reference point is a position at which a QR code is attached to the wheel disc.
