The invention provides projection equipment and a projection area correction method. When the projection area correction instruction is obtained, the projection device can obtain the mapping relation between the graphic card projected by the ray machine and the projection plane. According to the mapping relation, an initial projection area, namely a projection area before correction, of the graphic card projected to the projection plane by the ray machine can be obtained. The projection equipment can perform contour correction on the initial projection area to obtain the target projection area, so that the target area set by the user can be determined, and the target area can be a curtain. The target position information of the target projection area is determined according to the mapping relation, and the light machine can project the target graphic card to the target projection area, so that the projection area is corrected, the projection equipment is ensured to completely project the image to the curtain,
