Abstract

The embodiment of the invention provides a lens curved surface determination method, and the method comprises the steps: carrying out the iterative updating based on an initial curved surface, and determining a shaping curved surface which is used for reflecting the content of a light-emitting screen into eyes; each iterative update comprises the following steps: dividing a to-be-updated curved surface into a plurality of segments, and updating each segment based on a curved surface segment before updating, a reference curved surface segment and an update weight; the reference curved surface segment is a corresponding spherical surface segment taking a corresponding point on the light-emitting screen as a focus, and the updating weight is related to the position of the point to be updated.

Description

technical field [0001] This specification relates to the field of lens design, in particular to a method and system for determining a curved surface of a lens. Background technique [0002] With the development of science and technology and the needs of various scenarios, various glasses (such as AR glasses, etc.) appear. Glasses can satisfy the user's detection and experience of the real world and the virtual world, so the requirements for the lens of the glasses are getting higher and higher. However, the lens of the glasses used by the user has a small field of view angle and relatively large distortion. [0003] Therefore, it is desired to provide a method and system for determining the curved surface of the lens, which can transmit the optical signal of the display screen to the eyes of the user with a larger viewing angle and a smaller degree of distortion, so as to improve the physical examination of the user. Contents of the invention [0004] One of the embodimen...
