Problems solved by technology
The advantage of this method is that it can guarantee the resolution of each viewing angle picture, and theoretically, the number of viewpoints can be increased without limit if the hardware conditions are met; this method also has some significant disadvantages, the most prominent being the high cost, High energy consumption and complicated system modulation
At the same time, the size of the projector is limited, resulting in insufficient display brightness, making it difficult to apply outdoors

The present invention provides a multi-view naked-eye three-dimensional display system and a display method thereof. The system includes: a laser projector for projecting light; a scanning system for receiving the light projected by the laser projector and scanning it into an image; The image of the cylindrical lens grating forms a multi-view image; the cylindrical lens grating system includes the first cylindrical lens grating and the diffusion film, and the diffusion film is located on the side of the first cylindrical lens grating facing away from the plane mirror array; the image emitted by each plane mirror of the plane mirror array Two pairs overlap on the first cylindrical lens grating; the multi-view naked-eye three-dimensional display system and its display method of the present invention adopts a plane mirror array to replace the projector array in the traditional technology, which greatly saves cost and reduces energy consumption. At the same time, due to Using only one projector, the size of the projector will not be limited, and it can realize high-brightness projection, so it can be applied in various complex environments such as outdoors.
Description
technical field [0001] The invention relates to the field of computer vision technology and stereoscopic video, in particular to a multi-view naked-eye stereoscopic display system and a display method thereof. Background technique [0002] Stereoscopic display is a technology that projects different images in the left and right eyes to virtualize the depth information of the objects in the image, and finally realizes the stereoscopic display of the scene. The usual stereoscopic display has only one viewing angle, that is, no matter moving the viewing angle or the viewing position, the amount of information that the viewer can receive cannot be increased. [0003] The multi-view stereoscopic display is based on the ordinary stereoscopic display, and certain corrections are made to the device, so that the viewer can see different display images after moving a certain position or turning a certain angle. Although this display method has a certain gap compared with the holograp...
