Image processing applied to brick quality control

The results from an investigation into the feasibility of using image proce ssing in the quality control system at a particular brickworks is reported. Methods were developed that allowed the identification and measurement of cracks and surface indentations and protrusions, and the measurement of the area of uniform pink on the surface of the particular brick type considere d. It is concluded that the methods used could be developed relatively easi ly into a commercial real-time quality control system, which could result i n considerable cost savings. It is also concluded that quality control meas urements additional to those considered could easily be incorporated into s uch a system.
