Method and system for correcting visual depth of field of head-mounted display

The invention discloses a method and a system for correcting the visual depth of field of a head-mounted display, and the system comprises a first distance measurement unit which is used for judging a first distance between a first object and a viewer or a second distance between a second object and the viewer; and a first light direction adjuster and a second light direction adjuster for changing directions of the first light signal and the second light signal emitted by the first emitter and the second emitter, respectively, such that the first light signal and the second light signal are emitted toward the first eye and the second eye at a first angle and a second angle, respectively, wherein the first angle and the second angle are changed relative to the frontal plane of the viewer so as to present a binocular virtual image with variable depth-of-field feeling to the viewer. 本发明公开一种头戴式显示器视觉景深校正的方法和系统，其中所述系统包括：第一距离测量单元，用于判定第一物体与观看者之间的第一距离或第二物体与观看者之间的第二距离；以及第一光方向调节器和第二光方向调节器，用于分别改变由第一发射器和第二发射器发射的第一光信号和第二光信
