一种基于像差分析的非接触速度、长度检测方法

A contactless velocity and length detection method based on pixels difference analysis

传统机械方法测量移动物体的速度或移动长度,需用靠轮与被检测物表面直接接触,测量中易产生滑动误差和磨损,在许多工业场合无法应用。本文基于像差分析,给出了一种非接触的移动物体速度、长度检测方法,该方法具有准确、简单、稳定性好等特点,实用于各种工业生产过程中不同材质物品的移动速度及移动长度测量。

The traditional mechanical ways for detecting velocity and length need to keep the wheels contacting with the objects to be detected, which will easily cause sliding tolerances and abrasions and cannot he used in many industrial applications. Based on the method of pixels difference analysis, a contactless method to realize the detection of velocity and length of a moving object is proposed in this paper. With the advantages of simple structure , high accurate and great stability, this method can be applied in various industrial fields to detect velocity and length of objects with different materials.
