1. An optimal viewing angle adjustment method for a multi-dimensional spatial three-dimensional display screen, comprising:
step 1: setting optimal angle parameter data between the multi-dimensional spatial three-dimensional display screen and a viewer at a front end of the multi-dimensional spatial three-dimensional display screen;
step 2: disposing a detection device on the multi-dimensional spatial three-dimensional display screen for viewer identification and distance identification;
step 3: identifying a distance between the viewer and the multi-dimensional spatial three-dimensional display screen by the detection device in real time; and
step 4: transmitting a position and a direction of the viewer to the multi-dimensional spatial three-dimensional display screen, and controlling the multi-dimensional spatial three-dimensional display screen to zoom in or out according to the position and the direction of the viewer;
wherein the step 4 comprises:
step 4.1: sending an adaptive adjustment state request and displaying the adaptive adjustment state request on the multi-dimensional spatial three-dimensional display screen when the position of the viewer is detected to be unchanged at a fixed time;
step 4.2: confirming the adaptive adjustment state request, by the viewer;
step 4.3: taking a center point of the viewer as a fixed point, adjusting the multi-dimensional spatial three-dimensional display screen to swing left and ring, so that the viewer is in front of the multi-dimensional spatial three-dimensional display screen; and
step 4.4: taking the center point of the viewer as the fixed point; connecting two lines to two ends of the multi-dimensional spatial three-dimensional display screen, by the fixed point, where an included angle of the two lines is 60-120°.
