利用水下高速摄影机和水下照明灯对水下高速直线运动的物体进行拍摄，并通过分析连续拍摄的水下图像，比较不同图片之间运动物体的变化情况，可以计算出水下物体的运动速度。

Consecutive images of an underwater moving object can be gained using underwater high-speed camera and lamps to shoot the object . Through analyzing these images and comparing the differences of motion states between them , the velocity of the underwater moving object can be calculated .
