Augmented reality display device and method, and augmented reality glasses

An augmented reality glasses comprising:

• an augmented reality display device;
• and
• a frame and a temple,
• wherein, the augmented reality display device comprises:
• an adjustable light transmissive sheet, comprising a plurality of pixels, a light transmission of each of the plurality of pixels being controllable;
• a spatial three-dimensional reconstruction portion, configured to obtain a depth value of each real point of a real scene in a field of view of a user;
• and
• a controller, configured to compare a depth value of a virtual point displayed in a pixel with the depth value of the real point of the real scene corresponding to one of the plurality of pixels, when the depth value of the real point is greater than the depth value of the virtual point, the one of the plurality of pixels is controlled to be opaque;
• and when the depth value of the real point is smaller than the depth value of the virtual point, the one of the plurality of pixels is controlled to be transparent,
• wherein, the adjustable light transmissive sheet is provided in the frame, the spatial three-dimensional reconstruction portion is provided on the frame, and the controller is provided at the temple,
• wherein the spatial three-dimensional reconstruction portion comprises:
• a light emitter, configured to emit light, the light being reflected by the real scene in the field of view of the user to form reflected light;
• and
• an optical receiver, configured to receive the reflected light and determine the depth value of each real point of the real scene in the field of view of the user according to the reflected light,
• wherein the light comprises a structured light, and wherein the structured light comprises a standard stripe or grid light.
