Abstract
The present application provides a detection method of a crease degree of a screen and a visual detection device, the detection method includes: providing detection rays, and obliquely irradiating the detection rays onto a surface to be measured of the screen; acquiring detection rays reflected by the surface to be measured of the screen to obtain a corresponding light source reflection image; analyzing the light source reflection image to obtain deformation curvatures of the light source reflection image and taking one of a maximum deformation curvature and an average deformation curvature that are obtained through the deformation curvatures as an evaluation index of a crease degree of the screen; and evaluating the crease degree of the screen.
