The objective of this thesis is to present a prototype of an optical wood control system, concretely, an optical measurement system for bamboo boards intended for parquet flooring. We used The Imaging Source DFK 23G018 color cameras for optical detection and measurement. In this thesis we present four methods for processing the images of wooden boards. The first method finds the edges of the boards and measures individual dimensions. By knowing the exact position of the boards in the images, the remaining three methods detect holes in the boards and different kinds of imperfections and sort the boards into appropriate color groups. To simulate the control part of the process line we used a step actuator. The functionality and the management of the actuator are also explained.
