The invention discloses an intelligent adjustment projection system, and belongs to the technical field of projectors, and the system comprises a projector, a projection transfer mechanism and a positioning mechanism, the top of the projector is fixedly connected with a mounting column, the projector is internally provided with a light condensation mechanism, one side of the projector is fixedly connected with a lens cone, and the other side of the projector is fixedly connected with a camera. The outer side of the second bevel gear is sleeved with a projection transfer mechanism, and the outer side of the projection transfer mechanism is sleeved with a positioning mechanism. According to the invention, by arranging the projection transfer mechanism, under the action of two reflectors, light emitted by the projector can be effectively refracted to other positions, by arranging a motor, the motor drives a clamping block to rotate during working, the motor drives a first bevel gear to move downwards to be engaged with a second bevel gear, and when the motor drives the first bevel gear to rotate during working, the motor drives the first fixing cylinder and the second fixing cylinder to rotate under the effect of the second bevel gear, so that the light projection position can be effectively adjusted, and the light can be effectively projected on the curtain through double adjustment.
