ABSTRACT:
A method and system to monitor randomly oriented objects on a process line are disclosed. A color camera is used initially to collect a set of reference images of at least one reference object. The reference images represent various spatial orientations of the reference object. The reference object serves as the standard for the process. The reference images are stored in a computer-based platform. The color camera is then used to capture images of monitored objects as the monitored objects pass by the color camera on a process line. The monitored objects may have a random spatial orientation with respect to the color camera as the monitored objects pass through the field-of-view of the color camera. The captured images of the monitored objects are processed by the computer-based platform and compared to the reference images in order to determine if certain characteristic parameters of the monitored objects have deviated from those same characteristic parameters of the reference object. If so, the process may be adjusted to correct for the deviations in order to bring the process back into tolerance.
