  • Surface inspection method using mold surface inspection device
    Patent number: 11733685
    Abstract: The present disclosure relates to a surface inspection method using a mold surface inspection device, and more specifically, to a surface inspection method using a mold surface inspection device including a setting part in which an inspection object is set, a light source part configured to irradiate the inspection object with irradiated light so that a reflective highlight is generated on a surface of the inspection object, an imaging part configured to image the surface of the inspection object so that a highlight region where a reflective highlight is generated is included, and an image processing part configured to process an image imaged in the imaging part to provide the image to a worker so that the worker determines whether defects are generated on the surface of the inspection object on the basis of the image.
    Type: Grant
    Filed: September 30, 2020
    Date of Patent: August 22, 2023
    Assignee: GIST(Gwangju Institute of Science and Technology)
