摘要:
将数字图像处理技术用于转速的测量,提出了数字图像时间平均相关方法.将该方法与时间平均成像结合,只需获取被测物体在转动状态下的一幅图像及其在静止状态下的一幅参考图像即可确定该物体的转速.文中给出了求解问题的迭代算法.实验表明数字图像时间平均相关及其迭代算法用于测量分析物体的转速具有较高的精度.
Abstract:
Based upon digital-image time-average correlation, a new method was developed to nonintrusively measure the angular velocity of a rotating object. By this technique, for determining the angular velocity of a rigid body, only its static image recorded when it was motionless and its motion-blurred image captured when it was in uniform rotation were needed. An iterative algorithm was also presented to solve the derived nonlinear equation. It was shown that the time-average correlation method can be used to measure angular velocities of rigid objects with reasonable accuracy.
