The invention discloses a method and a device for correcting insufficient simulation of vertical acceleration in a missile separation launching test, and the method comprises the steps: obtaining a change curve of the motion characteristics of a carrier missile along with time through image recognition; according to the change curve of the motion characteristics of the carrier bomb along with time, an aerodynamic parameter identification method is adopted to obtain the aerodynamic coefficient of the carrier bomb in the carrier aircraft disturbing flow field; modeling the interference aerodynamic force of the carrier bomb by using the free flow aerodynamic coefficient of the carrier bomb and the aerodynamic coefficient of the carrier bomb in the interference flow field of the carrier aircraft; and carrying out kinematics simulation on the loaded projectile by utilizing the full-size kinetic parameters of the loaded projectile and based on the interference aerodynamic model of the loaded projectile, and obtaini
