Problems solved by technology

[0004] Since the lenses of AR glasses are set transparently, when the ratio between the light incident on the lens from the front of the wearer (incident light) and the light formed by the virtual image reflected by the lens (reflected light) is not coordinated, the The virtual image in the wearer's eyes will become too dim or too bright compared to the real scene, affecting the wearer's perception

Embodiment 1

[0059] A kind of AR glasses, such as figure 1 and figure 2 As shown, it includes a frame 1, a lens 2, a projection device 3, a power supply device and a controller, and also includes an adjustment mechanism for adjusting the intensity ratio of the incident light to the reflected light of the lens 2. The above-mentioned controller is connected to the projection device 3 for control, and controls the projection device 3 to project the set content to be projected onto the lens 2 .

[0060] The above-mentioned power supply device adopts an independent battery provided in the frame 1, or adopts a battery or other power supply equipment outside the AR glasses, and the AR glasses are electrically connected to the external power supply equipment through a power supply line.

[0061] The projection device is arranged on the frame (1), and the projection device is used to project the to-be-projected image on the lens facing the wearer's eye side, so as to utilize the reflection functi...

Embodiment 2

[0070] A kind of AR glasses, such as Figure 4 As shown, the difference from the first embodiment is that the adjustment mechanism includes an electrochromic film 8 fixed on the surface of the lens 2 or inside the lens 2 , or the lens 2 is set as an electrochromic lens 2 .

[0071] Wherein, the electrochromic film 8 or the electrochromic lens 2 is electrically connected with the controller and the power supply device, and its own transparency is changed according to the voltage output by the control terminal of the controller.

[0072] Compared with the first embodiment, the transparency of the lens 2 is controlled based on the electrochromic principle, and the control is simpler, more convenient and more flexible.

[0073] In specific implementation, as Figure 4 As shown, the electrochromic film 8 or the discolored area of ​​the electrochromic lens 2 covers the entire lens 2, that is, the transparency of the lens 2 can be changed as a whole. or as Figure 5 As shown, the ...

Embodiment 3

[0075] A kind of AR glasses, which is different from the second embodiment in that the adjustment mechanism includes a transparent display screen disposed on the side of the lens 2 away from the wearer's eyes, the transparent display screen is connected to the controller and the power supply device, and receives And in response to the control signal of the controller, the color and brightness of each pixel on the transparent display screen are controlled to change. The above-mentioned transparent display screen can be fitted with the above-mentioned lens 2. For the setting effect, please refer to Figure 4 . It can also be used as a shield 4, and its setting effect can be found in figure 1 or image 3 .

[0076] Since the color and brightness of any pixel can be changed on the transparent display screen according to the control signal, for example, a black pattern is displayed on the transparent display screen. Obviously, the light transmittance of the above pattern area wi...

Abstract

The invention provides AR glasses and a control method thereof, and relates to the technical field of visual projection devices.The AR glasses comprise a glasses frame, lenses, a projection device, a transparent display screen and a controller, the projection device is arranged on the glasses frame, and a to-be-projected image is projected to the lens facing the side of the eyes of a wearer so that the to-be-projected image can be projected through the reflection function of the lenses; reflecting the to-be-projected image to the eyes of the wearer; the transparent display screen is arranged on the lens on one side far away from the eyes of a wearer and is used for adjusting the intensity ratio of incident light to reflected light of the lens; the controller is connected with the transparent display screen and generates a control signal according to the to-be-projected image; the control signal is used for controlling the color and brightness change of each pixel point on the transparent display screen, so that the proportion of the light intensity of the real image and the light intensity of the virtual image in the AR glasses is more coordinated, the virtual image can be highlighted, the influence of the virtual image on the real image is greatly reduced, and the impression of a wearer of the AR glasses is improved.

Description

[0001] This application is a divisional application of a patent application entitled "AR Glasses and Control Method thereof". The application date of the original application is October 18, 2019, and the application number is 201910995950.5. technical field [0002] The present invention relates to the technical field of visual projection devices, in particular to AR glasses and a control method thereof. Background technique [0003] The working principle of AR (Augmented Reality) glasses is that the projection device in the glasses projects the image to be presented on the lens on the side of the glasses facing the wearer's eye, and uses the reflection function of the lens to reflect the above-mentioned image light to the wearer's eye. In the eyes of the wearer, an overlap of the real scene and the virtual image is formed on the retina of the wearer to realize the perception of augmented reality. [0004] Since the lenses of AR glasses are set in a transparent manner, when ...
