Abstract: A surface profile measurement visualization method of large aspheric lenses based on doubly-connected edge list (DCEL) are proposed, and a software system is designed and developed to realize it. Firstly, an improved data structure based on DCEL is proposed to load 3D model. The graphics units which compose the basic part of the software are modeled based on DCEL data structure. Secondly, the scene node which composes the display part of software is created by aspheric surface profile according to surface equation. And the measurement path is generated and displayed by the software. An experiment was performed on the noncontact measurement platform. The data were integrated and smoothed to compare with the equation of aspheric surface contour and then the peak-valley value and RMS value of the surface were calculated. The experiment indicates that the surface profile measurement visualization method is correct and stable.
