| 摘要 | To count cords embedded in a rubber sheet with good working efficiency while improving the reliability and accuracy, a method includes a step S1 of acquiring raw waveform data D1 by scanning the outer surface of the rubber sheet with a displacement sensor, a step S2 of obtaining first corrected data D2 by performing a moving average processing on the raw waveform data D1, a step S3 of obtaining second corrected data D3 by converting the amplitude center j of waveform of the first corrected data D2 into a straight line, a step S4 of obtaining concave-center-position data D4 in which the concave-center-positions Q between the cords are defined by positions of lowest points of valleys of the waveform of the second corrected data D3, a step S5 of obtaining first corrected concave-center-position data D5 in which, by comparing intervals K between the Q with an upper threshold Kmax and lower threshold Kmin therefor, the concave-center-positions Q are added/deleted, and a step S5 of obtaining second corrected concave-center-position data D6 in which, by comparing the total number (m) of the concave-center-positions Q in the first corrected concave-center-position data D5, with the number (n) of the cords 3, the concave-center-positions Q are added/deleted. | ||||||
