Abstract
A method, related system and related computer program product are provided for monitoring wear of teeth of a drum of a double roll crusher. A processor receives a digital video capturing rotation of the drum and the teeth. For each frame of the digital video, the processor segments the frame into groups of contiguous pixels, wherein each group is representative of one of the teeth. The processor determines parameter indicative of a geometry of at least one of the teeth based on segmented groups of contiguous pixels in at least one of the frames of the digital video. The processor generates a human-readable report based on the parameter indicative of the geometry of the at least one of the teeth.
