Summary:The invention discloses a three-dimensional sphere surface full-coverage projection device. The device comprises multi-level platforms and a spherical screen arranged between the multi-layer platforms. The spherical screen is a sphere, a plurality of projectors are uniformly arranged on the multi-layer platforms around a central axis of the sphere along a circumference. A warp and weft is arrangedon a surface of the sphere, projection sensing points are arranged at joint points of the warp and weft on the surface of the sphere. The projection sensing points are provided with projection sensors. Each projection sensor is connected with an induction transmission line for output. Each projector projects images of the spherical screen from different directions of the multi-layer platforms. The projection sensors sense projected images, and overlapped projection cutting is controlled by image control software so that three-dimensional spherical images can be displayed on the spherical screen. By using the three-di
