  • Basis weight measuring apparatus and method for sheet tobacco, and manufacturing system and method for sheet tobacco
    Patent number: 10051882
    Abstract: A measuring apparatus for performing a basis weight measuring method for sheet tobacco according to the present invention includes: a light source (28) that emits light to sheet tobacco (ST) passing through a measurement position (P) on a transport path (18); and a visual sensor (30), the visual sensor (30) having a color camera (32) disposed with the transport path (18) put between the color camera (32) and the light source (28), a processing part (40) that transforms a color image of the sheet tobacco (ST) taken by the camera (32) into a grayscale image, and a conversion part (42) that converts an average gray level of the grayscale image into a basis weight of the sheet tobacco (ST) with reference to a conversion map which indicates a relationship between the average gray level of the grayscale image and an actual basis weight of sheet tobacco (ST).
