Polarizer size measurement device

The invention provides a polarizer size measurement device. The polarizer size measurement device is used for measuring the plane size of a product. The device comprises a base, a shooting module, a control host and a display module, wherein the product is placed on the base; the shooting module is movably fixed on the base; the shooting module moves according to a pre-set track, and is used for shooting different areas of the product, and transmitting shot image data; the control host is electrically connected to the shooting module, and used for receiving the image data, grabbing the outlineof the product in the image data, obtaining the position coordinate of the outline in a current view, and simultaneously, measuring the size of the product in combination with the position coordinateaccording to the movement displacement of the shooting module, so that a measurement result is obtained; and the display module is electrically connected to the control host, and used for displayingthe measurement result. The
