Glass plane velocity measurement method based on binocular telecentric lens

The invention discloses a glass plane velocity measurement method based on a binocular telecentric lens, and the method comprises the following steps: S1, placing the device in the moving direction of the surface of glass, and enabling the lens to be perpendicular to the side surface of the glass; s2, adjusting the distance between the lens and the side surface of the glass; s3, initializing the two cameras, and setting corresponding acquisition parameters; and S4, the device is started, so that the lower edge of the glass appears from the upper lens and the lower lens in sequence. The upper lens detects whether the glass enters the visual field or not in real time, and if the glass enters the visual field, the upper camera and the lower camera respectively shoot two pictures according to a fixed time interval. And S5, processing and calculating the two pictures obtained by shooting to obtain the position of the lower edge of the glass in the picture, and calculating the accurate time interval of the two pict
