Abstract: The method and procedure to handle the disk digital photo by using AutoCAD was introduced in this paper.The digital photo was zoomed into the physical size through calculating the scale,then the width of the annual ring on the east-west and south-north direction was measured by using the measuring tool in AutoCAD.And the error of the disk digital photo’s deformation was analysed by disc simulation.The method is accurate,convenient and practical in the production practices.

Key words: disk, digital photo, stem analysis, AutoCAD
