Abstract

Over the past few years significant progress has been made in developing a computer vision system for locating and identifying defects on surfaced hardwood lumber. Unfortunately, until September of 1988 little research had gone into developing methods for analyzing rough lumber. This task is arguably more complex than the analysis of surfaced lumber. The prime motivation for developing such a system is the goal of creating an automatic grading system. This paper reports progress that has been made in developing a vision system for locating and identifying defects on rough lumber. It will point out some problems that are unique to the analysis of rough lumber and will report studies aimed at addressing these problems.
