PURPOSE:To measure the outer diameter of conveyed matter with high accuracy, by measuring the outer diameter of the matter to be measured on the basis of plural time series measuring data during a period when the matter to be measured is measured by each line sensor. CONSTITUTION:The outer diameter data of the matter 11 to be measured moving on a conveyor 9 are at first measured at plural places in a time series manner with respect to a certain direction by a first line sensor 13. Next, the outer diameter data in the direction having a definite angle to the above- mentioned direction are similarly measured at plural places by a second line sensor 15. These plural data are processed by a computer 18 and the shape based on the first line sensor 13 is further compared with that based on the second line sensor 15 and other data are corrected on the basis of max. value data receiving no effect of a speed and correcting operation is performed so as to allow both shapes to coincide with each other. |
