Abstract
A lift-up determining device includes a detector and a determination unit. The detector acquires a captured image including a tire on an axle of a vehicle and detects the tire from the captured image. The determination unit determines, based on a detection result by the detector, whether the axle is lifted up.
Claims12
A lift-up determining device comprising:
- a detector that acquires a captured image including a tire of an axle of a vehicle and detects the tire from the captured image;
- a determination unit that determines whether the axle is lifted up, based on a detection result of the detector;
- and
- a position determination unit that determines, when the tire is a middle tire located between a front-most front wheel tire of the vehicle and a rear-most rear wheel tire of the vehicle, whether a lowest point of the middle tire is higher than a baseline by a distance greater than or equal to a predetermined value, the baseline extending in a traveling direction of the vehicle from a lowest point of the rear-most rear wheel tire,
- wherein when the position determination unit determines that the lowest point of the middle tire is higher than the baseline by the distance greater than or equal to the predetermined value, the determination unit determines that the axle is lifted up.

A lift-up determining device comprising:
- a detector that acquires a captured image including a tire of an axle of a vehicle and detects the tire from the captured image;
- a determination unit that determines whether the axle is lifted up, based on a detection result of the detector;
- and
- a deflection determination unit that determines, based on the captured image, whether a local region of a road surface located directly under a lowest point of the tire detected by the detector is deflected by a distance greater than or equal to a predetermined value,
- wherein when the deflection determination unit determines that the local region is not deflected by the distance greater than or equal to the predetermined value, the determination unit determines that the axle is lifted up.

- a rotation determination unit that determines, based on the captured image, whether the tire detected by the detector is rotating;
- and
- a deflection determination unit that determines, based on the captured image, whether a local region of a road surface located directly under the lowest point of the middle tire detected by the detector is deflected by a distance greater than or equal to a predetermined value,
- wherein the determination unit determines whether the axle is lifted up, based on a determination result of the position determination unit, a determination result of the rotation determination unit, and a determination result of the deflection determination unit.

A lift-up determining method comprising:
- acquiring a captured image including a tire of an axle of a vehicle;
- detecting the tire from the captured image;
- determining, based on a result of the detecting of the tire, whether the axle is lifted up;
- and
- determining, when the tire is a middle tire located between a front-most front wheel tire of the vehicle and a rear-most rear wheel tire of the vehicle, whether a lowest point of the middle tire is higher than a baseline by a distance greater than or equal to a predetermined value, the baseline extending in a traveling direction of the vehicle from a lowest point of the rear-most rear wheel tire,
- wherein when it is determined that the lowest point of the middle tire is higher than the baseline by the distance greater than or equal to the predetermined value, it is determined that the axle is lifted up.
