Abstract
Systems and techniques for detecting and reporting conditions of a conveyor belt by receiving image data from at least one camera structured and arranged to capture an image of a portion of a conveyor belt, detecting an object in the portion of the conveyor belt based on the received image data, and generating status information associated with the portion of the conveyor belt based on the detected object.
