Title:
METHOD FOR FACILITATING AN IDENTIFICATION OF AN OPTICAL MARK AND DATA PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/038170
Kind Code:
A3
Abstract:
A computer-implemented method (100) for facilitating an identification of an optical mark (410) in an image (400) of a spectacle lens (402) is provided. The method (100) is characterized in that it comprises a step of generating (104) enhancement information based on the image (400) of the spectacle lens (402), wherein the enhancement information is configured to enhance a detectability of the optical mark (410) in an automated identification process when an impairing structure (406) impairs the detectability of the optical mark (410) in the image (400). Furthermore, the method (100) comprises a step of providing (106) the generated enhancement information to the automated identification process for identifying the optical mark (410) using the enhancement information.
