The invention discloses a space display platform angle distance active adaptation algorithm, and mainly solves the problem that a space display platform cannot actively adapt to changes of a user position and a visual angle. The realization process is as follows: (1) according to the data obtained by the face recognition technology, the positioning technology and the sensing technology, the orientation can be quickly determined, and the optimal distance between the display platform and the user is determined by combining the most comfortable viewing distance in the health model; (2) the vectordirection of the user's line of sight is calculated based on the analysis data of the user's overall shape; (3) the inclination direction and the height of the display platform are obtained accordingto the sight direction, and the specific position of the display platform is obtained by combining the previous data; and (4) the moving distance and the moving direction of the display platform arecalculated based on the influences of factors such as time, user comfort and eye fatigue. In the research self-adaption field, the method not only can meet the requirement that a user can watch a display platform comfortably to the maximum extent at different positions, but also has very high efficiency and accuracy.
