摘要： The quality measurement method for a long sheet material W includes measuring cellulose fibers, % moisture, and % ash of the paper web W by using area cameras 1102 to 1106 having an infrared light receiving element and a light source 1100 having an infrared light emitting LED element. Performance check for the infrared cameras 1102 to 1106 over the entire width and correction of measured values are performed by using consistency between measured values for the same point in an overlap area measured by adjacent cameras and reference samples 1107 at the off-sheet positions provided at both sides.

摘要： The invention relates to a method for illuminating a wood fibre web for deviation detection. The method comprises turning on LEDs of an overhead sidelight that are side-directed towards a first edge of the web for illuminating a first half of width of the web, capturing an image of the first half, turning off the LEDs, turning on LEDs of the overhead sidelight that are side-directed towards a second edge of the web for illuminating a second half of width of the web, capturing an image of the second half, and turning off the LEDs. The invention also relates to an overhead sidelight, a machine vision system, and a lighting system.
