A Cube Workpiece Positioning Method Based on Point Structured Light Scanning

In the automation upgrading process of traditional labor-intensive industries, positioning method of workpiece affects the automated operation quality, efficiency, and system cost directly. Traditional workpiece positioning methods based on image vision and line structured light usually require higher professional knowledge or cost, which increase the difficulty for widely application. Therefore, this paper proposes a workpiece positioning method based on point structured light scanning for cube-shaped workpieces. Positioning accuracy is analyzed and the feasibility of this method is verified through numerical example. The result of this research provides a precise and low-cost workpiece positioning method for the automation upgrade of traditional labor-intensive industries.
