Image processing method and computing device for augmented reality device, augmented reality system, augmented reality device as well as computer-readable storage medium

A computing device for an augmented reality device, comprising:

• an additional image generation module configured to generate an additional image according to a target object within a user's field of vision, wherein the additional image is viewable for the user and the resolution of the additional image is smaller than the resolution of a display area in the display screen of the augmented reality device;
• a position determination module configured to determine position information of the additional image with respect to the display area, the position information defining a target area for displaying the additional image in the display area, wherein the position information comprises coordinates of a reference point in the additional image in the display area and a rotation angle of the additional image with respect to the display area;
• a transmission module configured to output the additional image and the position information to the display screen;
• and
• a display image generation module configured to display the additional image in the target area to generate a display image,
• wherein the position of the target area in the display area is automatically adjusted according to the approximate form of the target object in the user's field of vision and its approximate position within the user's field of vision.
