System and method for detecting missing tooth in mining shovel

A system, comprising:

• an imaging device fitted on a rope mine shovel disposed on a rope mine shovel configured to carry a mining load, configured to acquire a plurality of image frames;
• a processing device communicatively coupled to the imaging device and configured to:
• receive a pair of image frames wherein the pair of image frames comprises a first image frame and a second image frame;
• detect a corresponding tooth line region for the pair of image frames to generate a pair of tooth line regions based on a shovel template set, wherein the shovel template set comprises a plurality of bucket template images, a plurality of tooth line images, a plurality of locations corresponding to the plurality of bucket template images, and a plurality of locations of tooth line images, and wherein the pair of tooth line regions comprises a first tooth line region in the first image and a second tooth line region in the second image;
• determine a difference image based on the pair of image frames and the pair of tooth line regions;
• determine a response map representative of possible tooth positions based on the difference image using a tooth template matching technique;
• select a tooth line among a plurality of candidate tooth lines based on the response map;
• determine a tooth condition based on the tooth line and the difference image;
• and
• notify the tooth condition to an operator of the rope mine shovel.

A method, comprising:

• receiving a pair of image frames from a camera disposed on a rope mine shovel configured to carry a mining load, wherein the pair of image frames comprises a first image frame and a second image frame;
• detecting a corresponding metal part region for the pair of image frames to generate a pair of metal part regions based on a shovel template set, wherein the shovel template set comprises a plurality of shovel template images, a plurality of metal part images, a plurality of locations corresponding to the plurality of shovel template images, and a plurality of locations of metal part images, and wherein the pair of metal part regions comprises a first metal part region in the first image and a second metal part region in the second image;
• determining a difference image based on the pair of image frames and the pair of metal part regions;
• determining a response map representative of possible metal part positions based on the difference image using a metal part template matching technique;
• determining a metal part condition based on the response map and the difference image and
• notifying the metal part condition to an operator of the rope mine shovel.
