Method for inhibiting shooting moire of LED film and television background screen

The invention discloses a method for inhibiting shooting moire patterns of an LED film and television background screen, and belongs to the field of image acquisition and imaging simulation. Aiming at the problem that an existing moire simulation analysis method is difficult to effectively guide the inhibition of moire in shooting practice due to the fact that model parameters cannot correspond to a real shooting process, the method comprises the following steps of: modeling and simulating screen dot matrix projection, virtual focus imaging and a sensor image acquisition process during shooting of an LED film and television background screen; and establishing a relation between the calculated and simulated shooting moire pattern effect and various parameters of the LED screen and the camera in the shooting process through a constraint inequality of sufficient inhibition of the moire of the LED background screen. Based on the moire simulation result and the inequality, the real shooting parameters for suppress
