Embodiment Construction
[0056] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0057] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

The invention discloses a uniformity compensation method, an optical waveguide system, and an augmented reality device. The optical waveguide includes a first optical waveguide and a second optical waveguide. The method includes: acquiring a first brightness distribution of the first optical waveguide and the second brightness distribution of the second optical waveguide; determine the first brightness distribution direction of the first optical waveguide and the second brightness distribution of the second optical waveguide according to the first brightness distribution and the second brightness distribution Brightness distribution direction: determining a first placement mode of the first optical waveguide according to the first brightness distribution direction and determining a second placement mode of the second optical waveguide according to the second brightness distribution direction. The invention provides a uniformity compensation method, an optical waveguide system and an augmented reality device, aiming at solving the problems in the prior art that the brightness of the outcoupling area is different and the image is not uniform due to the design and processing errors of the optical waveguide.
Description
technical field [0001] The invention relates to the technical field of optical imaging, in particular to a uniformity compensation method, an optical waveguide system and an augmented reality device. Background technique [0002] Augmented reality (Augmented Reality, AR) technology is a technology that integrates virtual information with the real world. When using augmented reality equipment, it is necessary to ensure that both virtual information and the real external world can be observed. [0003] Generally, the display system of an augmented reality device for displaying virtual information is usually composed of a display screen and an optical system. The image displayed on the display screen is transmitted to the human eye through the optical system. The image emitted by the display screen is transmitted by means of the method, and the image emitted by the display screen enters from the coupling end of the optical waveguide and emits from the coupling end.
