【Abstract】 A laser measurement system was designed in the paper,which could measure the hot-rolling wheel size by combining the principle of laser measurement and the method of vision measurement.The hardware structure of the measurement system and the measurement programs were described.At the same time,the way how to calibrate the target of measurement system was demonstrated,and the measurement of toroidal size at the condition of high temperature was carried out.The results showed that the single standard deviation of the wheel size measured at the condition of room temperature was 0.3865 mm,0.1862 mm and 0.1561 mm,respectively.When the measurement was carried out at 20 ℃ ~ 1000 ℃,the standard deviation was 0.0390 mm.更多还原
