Method for acquiring continuous video images by using high-speed photographing system

The invention provides a method for acquiring continuous video images by using a high-speed photographing system, which comprises the following steps of: firstly, connecting trigger interfaces of N high-speed cameras with different signal output channels of a multi-channel signal generator; secondly, aiming at a shooting object which moves at a high speed in a plane and moves in a spatial axial symmetry manner, ensuring that the distance from a lens to the shooting object is equal, and respectively adopting a plane placement manner and an annular placement manner; then, the focal lengths of the high-speed cameras are adjusted to be consistent, and when the high-speed cameras are annularly distributed, the heights of the high-speed cameras are guaranteed to be the same, and parameter setting of a signal generator is adjusted, so that different signal channels synchronously output square wave pulse signals with certain phase differences; setting the same resolution, exposure time and pre-trigger delay for diffe
