Device and method for photographing object moving at high speed

The invention relates to the technical field of object photographing and discloses a device and a method for photographing an object moving at high speed. The device comprises a triggering control unit, a pulse generator, a light source controller, a flash lamp and a camera, the pulse generator is connected with a triggering control board which is connected with the camera and the light source controller, and the flash lamp is connected with the light source controller. The method includes that the pulse generator converts moving information of the object moving at the high speed into a pulse signal and sends the pulse signal to the triggering control unit; the triggering control unit acquires realtime position and realtime speed of the moving object according to pulse quantity calculated by the pulse generator, generates a flash triggering signal and an exposure triggering signal according to the realtime position and the realtime speed, sends the flash triggering signal to the flash lamp and sends the exposure triggering signal to the camera. By the device and the method, accurate realtime speed of the moving speed can be acquired through a rotary encoder and a pulse grating ruler, so that optimized exposure and flash triggering signals can be acquired.
