Summary:The invention discloses a device and a method for measuring the edging width of a glass panel, a coaxial light source is utilized to irradiate the glass panel on a conveying device, and a half-reflecting mirror is positioned below the conveying device, so that a first reflecting region of an unedged part of the glass panel can be obtained when the coaxial light source irradiates; a second reflection area of the edging part of the glass panel and a third reflection area of the half-reflection mirror are arranged, and the second reflection area is located between the first reflection area and the third reflection area. Therefore, the surface of the glass panel, the edging surface and the background can be obviously distinguished after the camera shoots, so that the edging size can be measured, and the edging width can be calculated. In this way, the edging width is detected through one light source, the detection cost and the adjustment difficulty in the measurement process are reduced, and the measurement stab
