Problems solved by technology
However, due to the distance between the stereoscopic projection equipment and the projection screen, the two cannot be firmly connected together. During the projection process, if there is a slight touch, wind or vibration, etc. Movement or shaking will cause misalignment between the image projected by the projector and the lens unit of the lens array screen, which will cause distortion and blurring of the displayed image and affect the stereoscopic display effect

The invention belongs to the technical field of optical projection display, and in particular relates to a method for maintaining alignment of projected images of a stereoscopic projection device. The method is applicable to a projection device in which multi-pixel group images are projected on a lens array screen to achieve a stereoscopic display effect, and the steps include: setting an alignment reference point on the screen, setting a projection device fixedly connected to the projector, and simultaneously projecting A group of reference pixel groups are projected to the alignment base point, and sensors, controllers and adjustment mechanisms are set at the same time. When the reference pixel group deviates from the alignment base point, the adjustment mechanism adjusts the position or projection of the lens array screen or projector according to the offset signal. The angle is adjusted to align the reference pixel groups with the alignment reference point so that the pixel groups in the projected image remain aligned with the lens elements on the lenticular array screen. The method can effectively avoid misalignment between the projected image and the lens unit, so that the stereoscopic projection device can realize a continuous and stable stereoscopic display effect during the working process.
Description
technical field [0001] The invention belongs to the related technical field of optical projection equipment, and in particular relates to a method for maintaining alignment of projected images of a stereoscopic projection equipment. Background technique [0002] A projector is an optical instrument that projects images and videos onto a screen. It is widely used in homes, offices, schools and entertainment venues. Some projection equipment can realize stereoscopic projection and display, bringing a better viewing experience to the audience. In the existing optical stereoscopic display device, the principle that the lens array screen can reflect or refract light in different directions is used to realize the stereoscopic display, so that the viewer can watch the stereoscopic image without the aid of auxiliary settings, which is the realization of naked-eye 3D display. A more commonly used technical means. The prior art discloses an optical stereoscopic projection device (aut...
