Abstract
A system for inspecting a battery component includes a heating device configured to heat a surface of the battery component to a selected temperature, an optical-visible imaging device configured to take an optical image of the surface, a thermal imaging device configured to take a thermal image of the surface, and a processor configured to acquire the optical image and the thermal image. The processor is configured to correlate the thermal image with the optical image, identify a feature of interest in at least one of the optical image and the thermal image, determine a geometric characteristic and a temperature characteristic associated with the feature of interest, and determine whether the feature of interest is a defect based on the geometric characteristic and the temperature characteristic.
