In this paper we present a system for real-time quality inspection of wooden parts. The quality inspection system is based on computer vision and was developed for classifying wooden parts in an application with automated robotic handling operations. The quality inspection stands for evaluation of the surface quality, including image capture, and feature-based surface classification. The features are extracted from blobs and the classification algorithm relies on support vector machines. Based on our test results, the reliability of the classification is at a sufficient level.
