Glass fiber wettability detection method

The invention discloses a glass fiber wettability detection method. The method comprises the following steps: a detection mechanism is located on a sand outlet mechanism; the detection mechanism is matched with an internal industrial line-scan digital camera to shoot and collect a target area of the glass reinforced plastic pipe; the collected target area image is matched with an industrial line-scan digital camera to obtain an internal gray value of the glass reinforced plastic pipe image; the obtained gray value can be compared with a comparison threshold value of the equipment for judgment, whether the gray value is within a threshold value interval or not is known, and therefore whether the overall wettability of the glass fiber is qualified or not is obtained. And comparing the internal gray scale value proportion of the grey-scale map with a set threshold value proportion to judge whether the detection proportion accords with the set threshold value or not, so that the advantages of automatically measur
