    Based on the technology of laser-linear array CCD,a kind of high speed and high accuracy method on detecting the roller shape was put forward.Also the composition of the detective system and the operation process were expatiated.Aiming at the axes shifting of the roller during the detecting process,compensation steps were adopted from vertical and parallel the detecting surface.And it enhanced the accuracy of the detecting system effectively.At the same time the gradient intensity averaging method to process the signal of the CCD was adopted,which reduced the influence of the noise to the CCD image contrast,and enhanced the speed of data processing effectively.It also enhanced the accuracy and the resolution of the system remarkably.The experiments prove that the accuracy of the system can reach to the demand of practical production process.It provides a new method for the high speed,accurate and automatic on line detection of the roller shape.
