Image Processing Applied to Brick Quality Control

Abstract

The results from an investigation into the feasibility of using image processing in the quality control system at a particular brickworks is reported. Methods were developed that allowed the identification and measurement of cracks and surface inden-tations and protrusions, and the measurement of the area of uniform pink on the surface of the particular brick type considered. It is concluded that the methods used could be developed relatively easily into a commercial real-time quality control system, which could result in considerable cost savings. It is also concluded that quality control measurements additional to those considered could easily be incorporated into such a system.
