Abstract
A solution for evaluating a component of a vehicle, such as a brake pad of a rail vehicle, is provided. An imaging component can acquire image data for a target area of the vehicle within which at least a portion of the component is visible. The target area can be illuminated by an illumination device that is, for example, horizontally offset from the imaging device to highlight the three-dimensional structure in the target area by creating shadows in the image data. A set of points corresponding to the component can be identified in the image data using the shadows. A measurement for at least one attribute of the component can be calculated from the set of points.
Claims20
A system comprising:
- an imaging component including:
- a first imaging device configured to acquire image data for a target area of a vehicle;
- and
- a first illumination device configured to direct electromagnetic radiation on the target area, wherein the first illumination device is at least one of:
- horizontally or vertically offset from the first imaging device;
- and
- a computer system for evaluating a target component at least partially visible to the computer system in the image data of the target area using the image data by:
- locating a region of interest within the image data by identifying at least one component of the vehicle visibly located near the target component to the computer system in the image data, wherein the region of interest corresponds to a location in the image data where the target component is expected to be at least partially visible to the computer system;
- identifying, within the region of interest, a set of points in the image data corresponding to at least two-visible edges of the target component visible to the computer system, wherein the identifying the set of points includes locating intersection points visible to the computer system in the image data, each intersection point corresponding to an intersection visible to the computer system in the image data between at least one component of the vehicle adjacent to the target component and the target component;
- and
- calculating a measurement for at least one attribute of the target component using the set of points.

A system comprising:
- an imaging component including:
- a first imaging device configured to acquire image data for a target area of a rail vehicle, wherein the target area includes at least a portion of a brake assembly of the rail vehicle;
- and
- a first illumination device configured to direct electromagnetic radiation on the target area, wherein the first illumination device is at least one of:
- horizontally or vertically offset from the first imaging device;
- and
- a computer system for evaluating the brake assembly using the image data by:
- locating a region of interest within the image data by identifying at least one component of the vehicle visibly located near the brake assembly to the computer system in the image data, wherein the region of interest corresponds to a location in the image data where the brake assembly is expected to be at least partially visible to the computer system;
- identifying, within the region of interest, a set of points in the image data corresponding to at least two edges of the brake assembly visible to the computer system, wherein the identifying the set of points includes locating intersection points visible to the computer system in the image data, each intersection point corresponding to an intersection visible to the computer system in the image data between at least one component of the vehicle adjacent to the brake assembly and the brake assembly;
- and
- calculating a measurement for at least one attribute of the brake assembly using the set of points.

A method comprising:
- evaluating a brake assembly using image data for a target area of a rail vehicle, wherein the target area includes at least a portion of a brake assembly of the rail vehicle, the evaluating including:
- a computer system locating a region of interest within the image data by identifying at least one component of the vehicle visibly located near the brake assembly to the computer system in the image data, wherein the region of interest corresponds to a location in the image data where the brake assembly is expected to be at least partially visible to the computer system;
- the computer system identifying, within the region of interest, a set of points in the image data corresponding to at least two edges of the brake assembly visible to the computer system, wherein the identifying the set of points includes locating intersection points visible to the computer system in the image data, each intersection point corresponding to an intersection visible to the computer system in the image data between at least one component of the vehicle adjacent to the brake assembly and the brake assembly;
- and
- the computer system calculating a measurement for at least one attribute of the brake assembly using the set of points.
