摘要
设计了一种用于轧辊辊型非接触式检测的CCD传感系统,阐述了系统的检测原理、组成与检测过程。根据激光-线阵CCD检测技术原理,采用梯度强度均值法对检测信号进行处理,有效减小了噪音对成像质量的影响。利用插值法和数值滤波法处理数据,有效降低轴承振动和随机噪声的影响,提高了处理数据的速度。对辊型检测过程中易出现的轴线偏移现象,从垂直检测平面和平行检测平面2个方向采取补偿措施,有效地提高了系统检测精度。实验证明,系统的精度达到了实际生产过程辊型检测的要求,是一种快速、高精度的辊型检测方法。
A sensor-based system of non-contact detecting for roller shape was designed based on CCD. And the detective method, the composition of the detective system and the operational process were expatiated. Based on the detecting technology of laser-linear array CCD, the gradient intensity averaging method to process the measurment signals was adopted. It reduced the influ- ence of the noise to the CCD image contrast. By using interpolation method and value filtering to process the signals, the influence of random noise and the vibration of the roller bearing were reduced effectively. And all of above enhanced the speed of date pro- cessing. Aimed at the axes shifting of the roller during the detecting process, compensation steps were adopted from vertical and parallel the detecting surface. It enhanced the accuracy of the detecting system effectively. The experiments prove that the accuracy of the system can reach to the demand of practical production process for detecting roller shape. It provides a kind of high speed and high accuracy detecting method for roller shape.
