Popis: An automated PC-based machine vision system has been developed for measuring subsurface damage in glass based on the ball dimpling method [1,2]. The software automatically processes an image of the dimple and returns the SSD value. This paper provides a preliminary comparison of the result from this system and the result obtained by conventional visual measurements.
