Problems solved by technology

[0004] However, the inventors have found that at least the following problems exist in the prior art: in order to ensure a clear display effect, it is necessary to ensure that the image formed by the reflected light beam projected onto the screen is aligned with the image formed by the transmitted light beam projected onto the screen
In the actual operation of the theater, manually adjusting the coincidence of the transmitted beam and the reflected beam is a complicated and tedious task

Description

technical field [0001] The invention belongs to an automatically adjusted stereoscopic projection equipment and method, and further relates to the fields of effective alignment of graphic images, automatic control technology, stereoscopic display technology and the like. Background technique [0002] Generally speaking, three-dimensional stereoscopic image display is realized by projecting different images to the user's eyes. Conventional stereoscopic image display systems include single-projector systems that utilize a single projector to alternately and continuously emit stereoscopic image content comprising left and right images, utilizing left image polarizing filters and right image polarizing filters The left image and the right image are alternately filtered out and displayed on the screen, thereby achieving a stereoscopic display effect. [0003] However, in this single-projector type stereoscopic image display system, since the image light emitted by a single proje...
