Abstract

This paper presents the existing standard methods of measurement and determination of the proportion of glued wood failure surface, disadvantages of their use and comparison of standard methods with the new one. The new test method for the determination of the proportion of failure surface eliminates the flaws of standard methods and decreases the subjective effects of the examiner, and at the same time increases the precision of measurement. The method is based on images made with digital camera, which are then processed and analysed by computer. The results show that this method is more objective and more accurate than standard methods.
