摘要：A method and apparatus for measuring the length of fibers is provided. Themethod includes the steps of separating the fibers in order to obtain a fiber in singleform. The method further involves passing the fiber by an optical measurement systemthat optically images the fiber. Another step includes calculating the length of the fiberby measuring an increment of the fiber in the x coordinate plane, the y coordinate plane,and the z coordinate plane. Also, the method involves repeating this step to obtainadditional increment measurements. These measurements are placed into an equation tocompute the length of the fiber. The apparatus for measuring the length of separatedfibers from a fiber band includes an apparatus for separating the fiber from the fiberband. Further, a duct is provided for transporting the fiber. At least one camera is
proximate to the duct for obtaining an image of the fiber, and a computer is connected tothe camera. The computer is configured to assign numerical values to image points of theimage of the fiber in the x, y, and z directions. The computer uses the image points toincrementalize the image of the fiber. Also, the computer measures each increment andplaces the increments into an equation to determine the length of the fiber.
