Undercarriage inspection assemblies and systems

An inspection assembly comprising:

• one or more line scan cameras configured to capture images in a generally vertical direction;
• a first light source configured to emit light in a first direction that extends at least partially in the generally vertical direction and at least partially in a first horizontal direction extending from the first light source toward the one or more line scan cameras;
• a second light source configured to emit light in a second direction that extends at least partially in the generally vertical direction and at least partially in a second horizontal direction extending from the second light source toward the one or more line scan cameras, the second horizontal direction being substantially opposite the first horizontal direction;
• a housing comprising:
• a base configured to at least partially support the one or more line scan cameras, the first light source, and the second light source;
• a first shroud located proximate the first light source and sloped downwardly in the second horizontal direction;
• and
• a second shroud located proximate the second light source and sloped downwardly in the first horizontal direction,
• wherein the second shroud is spaced apart from the first shroud to thereby form a gap within which the first light source, the second light source, and the one or more line scan cameras are positioned,
• wherein the housing is configured to attach to a railway at a location between opposing rails of the railway;
• and
• one or more air curtains configured to blow air across a lens of a corresponding one of the one or more line scan cameras.

An inspection system comprising:

• a first inspection assembly comprising:
• a first angled camera oriented at least partially in a vertical direction and at least partially in a first horizontal direction, the first angled camera being directed to a first target region in a three-dimensional space from a first viewpoint;
• a second angled camera oriented at least partially in the vertical direction and at least partially in a second horizontal direction that is substantially opposite the first horizontal direction, the second angled camera being directed to a second target region in a three-dimensional space from a second viewpoint;
• an upright camera oriented substantially in a vertical direction, the upright camera being configured to capture images of a third target region in the three-dimensional space from a third viewpoint;
• one or more lights;
• and
• a first housing configured to attach to a railway at a first location along a railway, the first location being between opposing rails of the railway;
• a second inspection assembly comprising:
• one or more line scan cameras configured to capture images in the vertical direction;
• a first light source configured to emit light in a first direction that extends at least partially in the vertical direction and at least partially in the first horizontal direction;
• a second light source configured to emit light in a second direction that extends at least partially in the vertical direction and at least partially in the second horizontal direction;
• a second housing comprising:
• a second base configured to at least partially support the one or more line scan cameras, the first light source, and the second light source;
• a first shroud located proximate the first light source and sloped downwardly in the second horizontal direction;
• and
• a second shroud located proximate the second light source and sloped downwardly in the first horizontal direction,
• wherein the second shroud is spaced apart from the first shroud to thereby form a gap within which the first light source, the second light source, and the one or more line scan cameras are positioned,
• wherein the second housing is configured to attach to the railway at a second location along the railway, the second location being between the opposing rails of the railway and different from the first location;
• and
• one or more computing devices in electrical communication with the first inspection assembly and the second inspection assembly, the one or more computing devices being configured to:
• control operations of the first angled camera, the second angled camera, the upright camera, the one or more lights, the one or more line scan cameras, the first light source, and the second light source;
• and
• determine capture timings for each of the first angled camera, the second angled camera, the upright camera, and the one or more line scan cameras based at least in part on an estimated speed of a passing railcar such that the first angled camera, the second angled camera, and the upright camera are configured to simultaneously capture images of the passing railcar as the passing railcar passes over the first inspection assembly and the one or more line scan cameras are configured to capture images of the passing railcar as the passing railcar passes over the second inspection assembly.
