The invention relates to stereo projection systems for displaying stereopaired images on mirror-spherical or parabolic screens and for collectively watching a stereo effect without using stereo spectacles. Said invention makes it possible to continuously dynamically superimpose the projections of the left and right picture frames of a steropair with the user's left and right eyes, respectively. Such impositions are carried out simultaneously and independently for each viewer. The technical result is attainable by that the inventive stereo projection system comprises stereo projectors which are individually allocated to each viewer and in-series connected, a monitoring system for continuously and accurately determining the viewers' eye positions, a self correcting device, video-correcting devices, automatic drives for the mechanical self-correction of the stereo projectors and the system optical elements, units which are used for forming stereopair projected images in the stereo projector and which are coupled with the video-correcting device for the video-correction of the optimal parameters of the screen images. The inventive system makes it possible to carry out the self- and video-correction in an integral manner in such a way that the comfort of the stereo effect viewing is maximally satisfied.
