ABSTRACT:
A container inspection system for inspecting a moving container includes a radiation source positioned to direct radiation at the moving container. A radiation detector is positioned to receive a portion of the radiation from the radiation source that is not absorbed or blocked by the moving container and to generate electrical signals in response thereto. Processing circuitry produces multi-dimensional image data for the moving container based on the electrical signals generated by the radiation detector, and compares at least a first portion of the multi-dimensional image data to a corresponding portion of the multi-dimensional image data for a standard container. Thereafter, the processing circuitry determines, based on a result of the comparison, one or more characteristics of the container from the set of characteristics including the fill level of the container, whether the container is underfilled, whether the container is overfilled, whether the container is properly pressurized, and whether the container is sealed.
