A system that includes a detection device, an imaging device, and a control device is disclosed. The detection device may generate proximity data relating to a proximity of an undercarriage of a rail vehicle, and the imaging device may capture one or more thermal images of the undercarriage. The control device may receive a first thermal image and a second thermal image of the undercarriage. The first thermal image may be captured using a first integration time, and the second thermal image may be captured using a second integration time. The control device may determine composite thermal data associated with the undercarriage. The composite thermal data may include information mapping a first range of thermal data and mapping a second range of thermal data to one or more components of the undercarriage. The control device may cause an action to be performed in connection with the composite thermal data.

A thermal image auxiliary processing method includes the following steps. A reference part is prepared. A reference positioning point or a reference positioning surface is established with the reference part. A cutting tool or a grinding tool is positioned with the reference positioning point or the reference positioning surface. According to a thermal image, a determined positioning point or a determined positioning surface is obtained. Through the above method, the present disclosure can be used for auxiliary positioning and wearing measurement of the cutting tool or the grinding tool, as well as for measuring the size, the angle or flatness of an object to be measured. Therefore, the present disclosure can avoid the problems of increased equipment downtime and realign errors caused by manual and visual measurement.

A system for detecting a temperature of a railroad train wheel or bearing includes a thermal line scanner and a processor. The thermal line scanner is positioned to capture a plurality of thermal line scans of the wheel or bearing. The processor is configured to analyze each of the plurality of thermal line scans, identify a selected line of the plurality of thermal line scans, and calculate the temperature of the wheel or the bearing based on the selected line. Thus, the system and method disclosed herein reduce the acquired thermal data first to a single line for one or both of the wheel temperature and bearing temperature and then to single values.

An example system for inspecting railcar axles includes a flash source, an infrared camera, and a trigger sensor. The flash source is configured to apply a thermal pulse toward a surface of a railcar axle of a railcar wheelset, while the railcar wheelset is on a track. The infrared camera is configured to capture infrared data indicative of a thermal response of the surface of the railcar axle to the thermal pulse. The trigger sensor is configured to trigger the flash source to apply the thermal pulse based on a position of the railcar wheelset on the track. The example system can also include a processor configured to determine whether the captured infrared data is indicative of a crack on the surface of the railcar axle, and a vision camera configured to capture an image of the surface of the railcar axle.

Embodiments relate to systems in which one or more infrared cameras or sensors are used to measure heat related to the wheels of carts, such as shopping carts. Wheels with bad bearings, that wobble, or that have other issues preventing normal operation tend to generate more heat than wheels that are in good working order, such that an infrared camera or sensor directed at wheel height (e.g., about 2-3 inches off the floor) can detect wheel issues by detecting heat emitted by the wheels.
