Problems solved by technology

When displaying virtual objects based on objects in the real world, the slight displacement of the frame will cause the displayed position to be inaccurate. For example, from the perspective of the eyes, the virtual screw cap may not be screwed to the screw in the real world at all.

Embodiment Construction

[0018] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] exist figure 1 Among them, at a suitable position of the picture frame (1), the control circuit (2) can be placed on the temple, or the control circuit (2) can be placed on the upper edge of the picture frame directly in front of the picture frame (1). There are two lens groups on the left and right of the frame (1), and each lens group is composed of an outer lens (3b) and an optional inner lens (3a), wherein the outer lens (3b) is made of a TFT array (5) and other suitable layers to form a glare blocking lens. The camera module (4) can be positioned at the upper part directly in front of the mirror frame.

[0020] On the inner side of the upper edge of the frame, an optical flow positioning module (6) is placed, which emits light, preferably infrared light or infrared laser invisible to the human eye, to the human skin to realize th...

Abstract

The invention relates to an augmented reality realization method and device with an optical flow positioning function. Pixel-level augmented reality is realized based on optical flow positioning and aparticular display lens. The device comprises a camera module, a control circuit, an optical flow positioning sensor and an augmented reality lens set. The realization method comprises the steps thata control circuit is based on CPLD / FPGA / ASIC / CPU / DSP and the like, and is responsible for reading a digital video signal from one or more camera modules; a region therein beyond a certain brightnessthreshold is analyzed to carry out specific image operations, such as expansion and interpolation, to acquire the most suitable image; the center of the pupil of a human eye is analyzed according to optical flow positioning; and the image is displayed to augmented reality lens set to realize a certain degree of augmented reality effect.

Description

technical field [0001] The invention belongs to the field of augmented reality, and in particular relates to a pixel-level augmented reality method and device based on optical flow positioning and a specially customized lens group. Background technique [0002] In daily life, glare, as a common phenomenon, has a great impact on normal life and has caused harm to human vision health. Therefore, the suppression of glare has attracted the attention of many fields such as modern urban lighting and transportation. Blocking glare can also be said to be an augmented reality requirement to some extent. [0003] Now there are many technical solutions to try to solve the glare problem, and the typical ones are based on ordinary liquid crystal and electrochromic. Ordinary liquid crystals generally include TN / STN / TFT LCD panels, plus front and rear polarizers. The disadvantages of this type of solution have been pointed out in ZL2008200349991: due to the existence of polarizers, the o...
