Abstract

The disclosure provides an automatic wheel configuring device that configures a wheel according to the inclination of a hub of a vehicle. The automatic wheel configuring device includes a detection device. The detection device takes an image of the hub or the wheel of the vehicle, and detects the positions of the hub bolts or the positions of the bolt holes of the wheel. The detection device includes an acquisition portion and a circle extraction portion. The acquisition portion acquires basic position information on the positions of the hub bolts or the positions of the bolt holes of the wheel. The circle extraction portion extracts a plurality of circles present in the captured image. Among the combinations of a plurality of circles, the circle extraction portion extracts a combination that matches the basic position information as a combination of hub bolts or a combination of bolt holes.

First claim

What is claimed is:

1 . An automatic wheel configuring device for configuring a wheel according to an inclination of a hub of a vehicle, comprising:
a detection device, which takes an image of the hub or the wheel of the vehicle, and detects positions of hub bolts or positions of bolt holes of the wheel, wherein the detection device comprises:
an acquisition portion, which acquires basic position information on the positions of the hub bolts or the positions of the bolt holes of the wheel; and
a circle extraction portion, which extracts edges with circle elements in the captured image, detects a plurality of first circles formed by the edges with circle elements, extracts a plurality of second circles from the detected first circles according to a set radius, classifies the plurality of second circles into a plurality of groups based on center positions, and selects a plurality of representative circles from the plurality of groups based on roundness,
wherein among combinations of the plurality of representative circles, the circle extraction portion extracts a combination that matches the basic position information as a combination of the hub bolts or a combination of the bolt holes to configure the wheel.

2 . The automatic wheel configuring device according to claim 1 , wherein when there is no combination that matches the basic position information in the combination of the plurality of second circles, at least one imaginary circle is created, and in combinations of the plurality of second circles and the imaginary circle, the circle extraction portion extracts a combination matching the basic position information as the combination of the hub bolts or the combination of the bolt holes.
