Abstract
There is provided a computerized system comprising a processing unit and associated memory configured to obtain a three-dimensional dataset informative of at least part of a tread of a tire, and determine, using the three-dimensional dataset, data informative of tread depth of the tire.
Claims20
A system comprising one or more processing circuitries configured to:
- obtain a three-dimensional dataset informative of at least part of a tread of a tire, wherein the three-dimensional dataset comprises a plurality of points, wherein at least some of the plurality of points have a position in the three-dimensional dataset which depends on at least one of:
- (1) a viewing angle of the tread by a device, or
- (2) a curvature of the tread,
- generate a corrected height for at least some of the plurality of points which is independent of at least one of (1) and (2) according to a criterion,
- use the three-dimensional dataset and said corrected height for said at least some of the plurality of points to determine data informative of tread depth of the tire.
2 more elements
A system comprising one or more processing circuitries configured to:
- obtain a three-dimensional dataset informative of at least part of a tread of a tire,
- determine at least one surface in the three-dimensional dataset of the tread which is flat according to a criterion,
- determine a local direction orthogonal to the surface, and
- determine data informative of tread depth of the tire using the local direction.
1 more element
A system comprising one or more processing circuitries configured to:
- obtain a three-dimensional dataset informative of at least part of a tread of a tire,
- fit a predefined shape to a representation of the tread in the three-dimensional dataset, and unwrap the predefined shape fitted to the representation of the tread, or data informative of said predefined shape, into a surface to generate a map informative of height profile of at least part of the tread.
A system comprising one or more processing circuitries configured to:
- obtain a three-dimensional dataset informative of at least part of a tread of a tire, wherein at least one image used to generate the three-dimensional dataset has been acquired by an imaging device from a first angle relative to a longitudinal direction perpendicular to a surface of the tread, and wherein the tire has been illuminated by an illumination device from a second angle relative to the horizontal direction, wherein the illumination device and the imaging device are positioned so as to have the first angle being smaller than the second angle, and
- determine, using the three-dimensional dataset, data informative of tread depth of the tire.
