Augmented reality display method based on a transparent display device and augmented reality display device

An augmented reality display device, comprising:

• a transparent display device disposed between an user and an object;
• a first camera unit for obtaining a face image of the user;
• a second camera unit for obtaining a field image at a back side of the transparent display device;
• a processor being configured to perform step of:
• determining a viewpoint of the user based on the face image, and determining a first three-dimensional coordinate location of the viewpoint of the user related to the transparent display device;
• determining the object in the field image based on the field image being obtained, obtaining the auxiliary information of the object, and determining a second three-dimensional coordinate location of the object related to the transparent display device;
• determining a position of the object on a viewing region of the transparent display device according to the first three-dimensional coordinate location and the second three-dimensional coordinate location;
• determining a displaying position of the auxiliary information of the object on the transparent display device according to the position of the object on the viewing region, and controlling the transparent display device to display the auxiliary information of the object at the displaying position.
