设计出一种非接触式高速运动物体速度测量系统,在CCD单帧曝光时间内利用闪光灯对飞行中的物体进行两次闪光照明,CCD对两个不同位置的飞行物体成像,设定两个光脉冲之间的时间间隔以及测量出两个物体像之间的距离即可算出其飞行速度.该系统能够进行实时测量,突破了空间单点测量技术的局限,可在同一幅图像上记录下不同时刻多个空间点目标的图像信息,以及同一时刻不同空间点目标的图像信息,从而可以获得目标运动的瞬时速度.
A non-contact, high-speed moving object velocity measurement system was designed to flash two objects in flight with a flash during the CCD single-frame exposure time. The CCD imaged two flying objects at different positions and set two lights The time interval between pulses and the distance between two objects can be calculated to calculate the flight speed.The system can make real-time measurements, breaking the limitations of spatial single-point measurement technology can be recorded in the same image under different The image information of multiple spatial points at a time, and the image information of the target at different spatial points at the same moment, so that the instantaneous speed of the target movement can be obtained.
