Abstract
A method, system and computer program product are provided for monitoring a transverse position of a conveyor belt or its material load. A processor receives a digital video or digital images capturing movement of the conveyor belt and the material load. The processor segments the images or frames into a group of contiguous pixels representative of the conveyor belt, and the material load, such as by moving object detection, using background segmentation and threshold processing, pixel intensity-based segmentation or image texture-based segmentation. The processor determines a pixel coordinate of the group of contiguous pixels, which is indicative of the transverse position of the conveyor belt or the material load. The processor generates an alarm or report or a data signal, which depends, directly or indirectly, on the determined pixel coordinates.
