Abstract

Disclosed are an angle measurement method and measurement device applied to an optical system. The optical system comprises a lens and a display screen. The display screen includes test marks, and the test marks include a first mark and a second mark. The angle measurement method comprises: acquiring a first spacing distance between the first mark and the second mark (S100); acquiring a first optical signal of the first mark and a second optical signal of the second mark (S200); obtaining a first height value based on the first optical signal and a second height value based on the second optical signal (S300); and obtaining a first included angle between the lens and the display screen according to the first height value, the second height value and the first spacing distance (S400). The angle measurement method and measurement device applied to the optical system solve the problem of unmanageable and poor assembling quality of the optical system in the existing art due to the failure in directly measuring the angle between the lens and the display screen in the optical system.

Description

technical field [0001] The present application relates to the technical field of optical measurement, in particular to an angle measurement method and a measurement device applied to an optical system. Background technique [0002] Virtual reality (Virtual Reality, VR) technology is an advanced human-computer interaction technology that comprehensively applies various technologies to create a realistic artificial simulation environment, and can effectively simulate various sensory system behaviors of people in the natural environment. The VR optical system is mainly composed of lenses, display screens and structural parts. Among them, the assembly position relationship between the lens and the display screen directly affects the imaging quality of the optical system. During the assembly process of the lens and the display screen, there is usually an angle error, and The included angle error cannot be directly measured, so that the assembly quality cannot be controlled during...
