摘要

使用照相机进行非接触式测量具有很大的潜力。本文探讨了利用频闪效应确定旋转或周期性重复动作的运动参数的可能性。这种现象由高速摄像机记录。利用相机设置算法,被测量的运动物体可以在光学上减速、停止或反向运动。整个测量过程可以作为快照记录下来。在一个模型(直流电机)上测量了运动参数,并为测量结果确定了适当的滤波方法。

Stroboscopic Measurement of Kinematic Parameters Using Highspeed camera
The non-contact measurement by using the cameras has a high potential. The paper deals about possibilities to determine the kinematic parameters of rotating or periodically repeating actions using the stroboscopic effect. This phenomenon is recorded by a highspeed camera. Using the camera setup algorithm, the measured moving object can be optically slowed down, stopped or this object can move in the opposite direction. The whole measurement can be recorded as a snapshot. Kinematic parameters were measured on a phantom (DC motor) and the appropriate filter method was determined for results.
